Prof. Lidija Fras Zemljič, Vice-Dean for Research FS in cooperation with the Service for Research Activities BRIEF HISTORY The beginnings of the activities of the Faculty of Mechanical Engineering of the University of Maribor (FS Maribor) date back to 1959, when, on 26 November, the People's Assembly of the Republic of Slovenia adopted the Act on the Establishment of the Higher Technical School in Maribor. Departments were established of Mechanical Engineering, Textiles and Electrical Engineering. The Department of Textile Technology has remained an integral part of the faculty to this day. In 1973, the Higher Technical School developed into a college, and its largest department, the Department of Mechanical Engineering, began to implement a four-year Study Programme. We were the first to start postgraduate studies in Mechanical Engineering and awarded the first Master's and Doctorate degrees in 1976. In 1975, the College of Engineering became a member of the newly established University of Maribor, and, after ten years, it developed into the Faculty of Engineering, with the Department of Mechanical Engineering becoming one of the four departments of the Faculty of Engineering, with programmes in Mechanical Engineering and Textile Engineering. By 1995, the Faculty of Engineering had expanded to such an extent that it was transformed into four Faculties (the Faculty of Mechanical Engineering with the Department of Textiles, the Faculty of Civil Engineering, the Faculty of Computer and Information Science, and the Faculty of Chemistry and Chemical Technology). Today, the Faculty of Mechanical Engineering contributes to the development of science, and to the technological progress of the economy and the social environment by combining high-quality scientific research, professional and educational work in the field of Engineering Sciences. The highest values of our work are:  excellence, autonomy and openness of research and educational work,  honesty, sincerity, professional ethics and social responsibility in research and education,  the orientation of research and education towards the well-being of humanity and the creation of an inclusive society. 1 FACULTY ORGANISATION Name of the institution: University of Maribor, Faculty of Mechanical Engineering Address of the institution: Smetanova ulica 17, 2000 Maribor Web page: www.fs.um.si Dean Prof. Matej Vesenjak Tel: +386 2 220 7501 E-mail: tajnistvo.fs@um.si Vice-Dean for Studies Assis.

The heat engines are crucial for electricity and heat production. Currently one of the research areas is focused on conversion of plastic waste into fuel and its possible usage in internal combustion engines and other heat engine. The focus is on fuel injection, spray formation and possible effects on emissions formation. The laboratory disposes with own data acquisition (DAQ) system for temperature, pressure, displacement and flow measurements under different operating conditions. The staff uses NI software and hardware for measurement. The software for data acquisition, analysis and process control is developed for each application using the LabVIEW environment. MAJOR RESEARCH EQUIPMENT Internal combustion engine test bench The test bed consists of two engine brakes, Zoellner B-150 AC and Zoellner B-350 AC. The engine brakes enable rotational speeds of up to 6500 min-1 and maximum torques of 1000 Nm and 2000 Nm. The supporting measuring equipment enable measurements of air flow, fuel consumption, temperatures and emissions. It is possible to measure in cylinder pressure. Testing Facility for Mechanical High-Pressure Injection Systems Friedmann & Maier The Friedmann & Maier test facility is dedicated to testing classic in-line diesel engine pumps. The system is additionally equipped with numerous sensors (pressure, needle lift and temperature), and is connected to the NI DAQ system for data acquisition. 8 High-pressure chamber for fuel spray development recording The chamber was developed according to our experience and requirements and is designed to enable the study of the development of the fuel spray jet under the conditions prevailing in the combustion chamber of a diesel engine at the time of fuel injection (pressures up to 60 bar). The chamber provides optical access from four directions and has a separate inert gas supply (N2). The chamber can be used in conjunction with a test bench for mechanical high-pressure injection systems. Laboratory Pyrolysis Reactor The reactor allows the thermal decomposition of various polymer, composite or natural materials to be carried out. Processes in the reactor can be performed in inert atmosphere (e.g. N2) at temperatures up to 450 °C. Heat is supplied using an electric heater, which allows us to regulate the temperature in the reactor chamber. The system is computer-controlled (LabVIEW) and enables computer data acquisition and processing of measurement data. Measuring system for measuring pressure fluctuations and filter loads The system was developed for the pharmaceutical industry, for the purpose of validating the microfiltration process and analysing the factors that affect the load on filters due to the operation of quick-shut-off valves. The system works on the deterministic system NI cRIO 9047 and enables adjustment of valve timing and measurements the valve stroke, pressure waves, fluid flow and temperature.

MOST IMPORTANT RESEARCH ACHIEVEMENT The research discusses the influence of fuel properties on the occurrence of cavitation inside the injection nozzle of a diesel engine, and on the process of primary breakup of the injected fuel spray jet. The part of the study, that deals with the phenomena of cavitation inside the injection nozzle, was performed using CFD computational program AVL FIRE. The process of primary spray jet breakup, was monitored experimentally, using a high-pressure fuel injection chamber and a high-speed camera. To process the images, obtained with the high-speed camera, an innovative method has been developed in the LabVIEW software environment, which allowed us to determine the length and angle of the injected fuel spray jet. The results obtained indicate that the geometry of the injection nozzle has a major influence on the occurrence of cavitation, and that small changes in fuel properties do not have a significant effect on the angle and length of the fuel spray jet. From the comparison of numerical and experimental results can be concluded, that the occurrence of cavitation in the injection nozzle hole has a significant influence on the primary spray jet breakup, which is accelerated in the area od cavitation phase occurrence.

MOST IMPORTANT RESEARCH ACHIEVEMENT Research on the behaviour of inhaled droplets in the human airways. As the Covid epidemic evolved, we responded and contributed to the understanding of droplet deposition in the human respiratory tract. We investigated the influence of activity level, age, room size, and compared the behaviour of exhaled droplets with the behaviour of droplets produced by sneezing and coughing. Furthermore, we developed a numerical model that allows simulations of flows with particles that are non-spherical in shape. In process and environmental engineering, we often encounter problems involving the movement of non-spherical particles in liquids. PUBLICATIONS 1.

In such cases, computer simulation of the operation of the device can reveal the causes of the defects, which allows engineers to identify these defects already in the process of developing the device, and eliminate them, or improve the performance of the device. Especially for devices that operate with liquids (gases or liquids), optimisation with classical engineering approaches such as dimensional analysis and model experiments is of very limited use, which highlights the importance of computer simulation in the development of these systems. The field of development of computational methods for simulating the flow of liquids and the transfer of heat and mass in multiphase systems, which characterises what is happening in most process devices, is, thus, the central area of the laboratory's research work. With the advancement of the computing power of accessible computer systems, research work overlaps increasingly with research and development work for the Slovenian industry, which is recognising the added value of such solutions increasingly, as well as for international companies. Among the many examples of good practice, we highlight the development of the sublimation drying model, which is the basis of the developed digital twin of the freeze dryer for use in pharmaceuticals, the model of fouling and loading of the microfiltration membrane for the implementation of sterile filtration, the spray drying model, and the development of advanced models for the analysis of thermal and moisture loads in modern automotive lighting.

MOST IMPORTANT RESEARCH ACHIEVEMENT Development of a computer model of freeze-drying for use in scale-up procedures in pharmaceutical practice. The modelling and simulation of the freeze-drying process for use in the development and transfer of the technological process, developed within the framework of a long-term cooperation with the company LEK, enables a better understanding and simplification of the development and transfer of the process, the reduction of costs and the reduction of energy consumption consumed in the freeze-drying process. The developed computational model and virtual simulation of freeze-drying enables faster and more cost-effective development and transfer of the process, and, since the development is based on knowledge and understanding of the process, the risk of errors and problems is also reduced in large-scale technological transfer i.e. scale-up 14 procedures.

In addition to the ability to predict flow and flow phenomena with Computational Fluid Dynamics (CFD), the prediction of the occurrence of erosion due to cavitation and particles in the flow is of great importance for the design of hydraulic systems. We compiled a numerical model that allows the prediction of erosion due to cavitation and particulate matter as part of a commercial CFD programme and validated it on the example of a Venturi channel.

The focus of the basic research work of the LTN laboratory includes the development of modern analytical and numerical models for the analysis and optimisation of transport, lifting, mobile robotic and warehouse order-picking systems. The industrial (applied) research is focused on the development and construction of prototypes of transport and lifting technology, warehouse order-picking systems, logistic analysis of material flow in intralogistics, the use of sensor systems and the identification and tracking of logistics processes. In our work, we use modern Standards and Technical Regulations, as well as special computer-aided tools that enable the development, modelling, simulation, optimisation and analysis of transport and lifting technology, and warehouse order-picking systems. MAJOR RESEARCH EQUIPMENT ANSYS ROCKY Synopsys, Inc. is a specialised computer-aided tool for the modelling and analysis of the transport of bulk materials and powders and is based on the discrete element method (DEM). With the Ansys Rocky tool, we can precisely study the dependencies and relationships between individual particles that occur in the transport phase. The latter is crucial for understanding particle transport, and increasing the efficiency of transport systems in terms of achieving the required capacity, analysis of mixing processes, measurement of the wear of exposed parts of the conveyor, analysis of resistance during transport, etc. SOLID WORKS Dassault Systèmes for the design and modelling of transport and lifting devices is a powerful software tool for computer-aided CAD design. In the LTN laboratory, we use SolidWorks to design various engineering challenges, with an emphasis on modelling conveyor and lifting devices and their systems. SolidWorks is distinguished by several key functionalities, including the ability to model in 3D, the creation of technical drawings and plans, and the implementation of structural analyses of transport and lifting devices. AUTO CAD Autodesk, Inc. is a software tool for the design of transport and warehouse order-picking systems that is used in the LTN laboratory for logistic analyses of material flow in the design of transport and storage systems. AutoCAD allows you to display the layout of the production and warehouse system or logistics processes with the precise technical drawings, plans and 3D models. 33 The device, for the characterisation of powders with a rotating drum, was manufactured in the LTN laboratory, and is intended for the material characterisation of bulk materials (powders), which includes the analysis of the dynamics of the bulk angle, cohesion index and internal friction. It is used to determine the properties of powders in transportation. The LTN laboratory also uses its own software and modules, which are developed within the API Application Programming Interface. The latter allows us to customise and improve our tools for optimal performance in specific projects.

Prof. Tomaž Vuherer, IWE, IWI-c E-mail: tomaz.vuherer@um.si Tel.: +386 2 220 7677 Web: https://www.fs.um.si/laboratorij-za-varjenje/ The laboratory has excellent research equipment, and special knowledge in the field of testing materials and welded joints, which enables us to carry out scientific research and development activities in the field of welds, materials and welding technologies. Our fundamental focus is on the characterisation of welds and joints, especially metallic, polymer and composite materials. The goals of our research are the design and optimisation of welding technologies, and the achievement of the desired mechanical, technological and metallurgical properties of welded and joined materials throughout the life of the welded joint. Our laboratory specialises in performing various mechanical tests, fracture mechanics, material fatigue and crack growth analysis, which is confirmed by our excellent expertise in the field of material testing and welded joints. MAJOR RESEARCH EQUIPMENT Vibrophore 100 Zwick is a resonant tearing machine with a capacity of 100 kN, which is designed for the fatigue of materials, production of S-N curves and Wöhler curves with frequencies up to 100 Hz. Testing can be carried out on tension or bending. By pre-setting the machine, it is possible to perform static tensile, bending and shear tests on it. It is also intended for fracture mechanical tests, to produce cracks before testing, for the performance of fracture mechanical tests and for marking after the fatigue test. The machine is shared with the Structural Evaluation Laboratory. Varmig 271-i LCD (MAG, MIG, FCAW, SMAW); VARTIG 221 AC/DC (TIG, SMAW); VPS 4000 (MAG, MIG, FCAW SMAW); Welbee 500L (MAG, MIG, FCAW, SMAW) Daihen Varstroj; AVP A13, Rade Končar 1000 A (EPP) AVP; Flame Welding & Cutting Kit Messer. The equipment enables the production of welded joints using REO, MAG, MIG, TIG, EPP, FCAW procedures, as well as cutting of the base material and welds. The instrumented Charpy pendulum Amsler RPK 300 with its own Vuhi-Charpy 2024-ver1 program, is intended for an in-depth study of impact testing, where the total fracture energy can be determined, which is divided into crack formation energy and crack propagation energy. Also determined are the behaviour of the material during the fracture itself and the percentage of tough fracture. The Amsler 20 t servo hydraulic tearing machine is designed for static testing of welds and materials. Tensile, compressive, bending and shear tests of welds and materials can be carried out on it. The capacity of the tearing machine is 200 kN, and it has a tensile area and a pressure zone. With the machine's own instrumentation and extensiometers it is possible to capture signals directly on the computer. The following are available: - screw fixtures from M6 to M24, round fixtures from Æ2 to Æ25 mm and flat fixtures up to 20 x 50 mm. 36 The Rumul Cracktronic 160 Nm is designed to measure crack propagation in material and weld under dynamic loads. The machine is resonant, which allows for rapid cyclic loading of materials with a frequency of up to 100 Hz. It is possible to produce Wöhler and S-N curves for materials and welded joints. It is also intended for the manufacture of cracks for fracture mechanics in the phase of pre-fatigue and in the phase of fatigue of material and welds. The Rumul Fractomat, in combination with the Rumul Cracktronic 160 Nm, makes it possible to monitor crack growth under different dynamic loads in materials and welds. This is possible by tearing the foil, which is glued to the material and allows the crack to be measured to 1 mm accurately. With this, it is possible to determine the rate of crack propagation and the Paris curve of how the crack spreads through a particular material or weld. These allow us to predict the remaining service life of a material or component made of that material. The fractomat is portable and can also be used on other machines, such as the Vibrophore 100, or elsewhere in the field to monitor crack growth under dynamic loads. Smitweld Welding Thermal Cycle Simulator 1405 Smitweld The welding thermal cycle simulator is an excellent choice to produce microstructures that occur in the heat-affected area, such as the coarse-grained part of the HAZ, the fine-grained part of the HAZ, the inter-critical part of the HAZ and the subcritical part of the HAZ. This allows for a comprehensive study of the individual parts of the HAZ that occur in the weld. It also allows you to simulate the formation of residual stresses resulting from impeded shrinkage during welding. Smitweld 1405 - 10 kN tensile machine Smitweld The mechanical tensile machine is designed for static tensile, compressive, bending and shear tests. It can also be used to perform dynamic tests with a low fatigue frequency, so that the test subjects do not heat up during fatigue, and it is also suitable for testing composite materials and plastics. In addition, tensile compressive load cells of 20 N or 200 N can be connected to it, which is suitable for testing samples with a small cross-section. When we connect a CMOD sensor to the machine, we can perform fracture mechanical tests on it. The Vishay RS200 Vishay is designed to measure macro residual stresses on material and welded joints. The system works by measuring micro deformations due to drilling a hole that deforms due to residual stresses present in the material. Measurements are carried out with a three-element resistive measuring rosette, which is glued to the material. With the help of three Wheatstone bridges that measure deformations in individual strain gauges, deformations can be measured, and the released residual stresses can be calculated. We get the principal residual stresses and the angle of orientation of the principal residual stresses with respect to the position of the measuring rosette. 37 The Zwick rotary bending machine UBM-200 is designed for dynamic loading with rotary bending for determining S-N and Wöhler curves on materials. It can operate in displacement control or in force control at frequencies up to 85 Hz. It can be used to test materials for fatigue and predict the service life or remaining service life of materials, components and welds. The machine can handle loads of up to 200 Nm. On the machine, we can produce a fatigue crack on the test pieces of round shapes with a pre-prepared notch. Then, the specimens are used for fracture mechanics. Wild M10 Leica Stereo Optical Microscope Leica It allows you to observe and measure cracks that occur in the material, or when the material is fatigued. It is indispensable in the measurement of crack shape, in the evaluation of fracture-mechanical tests, where the shape and front of the fatigue crack and the crack propagation in the fracture-mechanical test are measured on the fractured surfaces of the specimen. It allows magnifications of up to 200x with different angles of exposure. Shimatzu Hardness Meters HMV-2000 Shimatzu They are designed for semi-automatic hardness measurements according to Vickers, Brinell and Rockwell. The Shimaztsu HMV-2000 hardness meter allows you to measure hardness and microhardness according to Vickers with a load of 2 g to 2 kg on the material, or in various microstructures of the welded joint. The microscope has a hardness meter that allows magnifications of 100x and 500x. Zwick 3202 Hardness testers Zwick is also designed to measure hardness according to Vickers and Brinell, where it is possible to measure hardness with weights up to 10 kg. The portable kraut gauge is designed for field hardness measurements using the Vickers and Rockwell method. Measurement System National instruments It is designed to capture deformation signals from resistive gauge sheets, to measure force, displacements, accelerations and pressures on various machines during operation and testing. It is also possible to transfer the equipment to the field and carry out measurements of various quantities there. A data acquisition speed is possible up to 2 M/s. The equipment consists of various modules – an SCXI 1000 housing, SCXI1100 voltage + thermocouples, an SCXI 1520 Wheatstone bridge amplifier, SCXI 1314, SCXI terminal blocks, and several data capture cards with different data capture speeds with additional sensors.

With the help of a magnetic sensor, the total energy for refraction can be divided into the energy for refraction, the energy for initiation and the energy for the propagation of refraction. It is also possible to determine the moment when the crack is initiated from the mechanical notch. Capture occurs at a frequency of 4 x 106 data per second. The data, however, are processed in a self- developed Vuhi – Charpy program. The data in the instrumented Charpy test shall be used on heterogeneous materials, such as welded joints, and materials for military purposes. They also use our program for military purposes at home and abroad. The results obtained from the Charpy hammer experiment are used for research purposes, where quite a few publications have been published. PUBLICATIONS 1.

MOST IMPORTANT RESEARCH ACHIEVEMENT Development of new high-strength aluminium alloys. Cooperation in the development of new commercial aluminium alloys of the 6086 group. We have developed a new type of aluminium alloys that have three types of nanoparticles in their microstructure, which are well resistant to elevated temperatures, while, at the same time, providing high levels of strength at room temperature, for which we have obtained the European EPO patent. These types of nanoparticles are icosahedral quasicrystals, dodecahedral quasicrystals, and an ordered crystal phase, with the structure L12. The main advantage of these alloys is that large cooling rates are not required to achieve the desired microstructure, and the appropriate size and arrangement of nanoparticles is achieved by stepwise heat treatment. Heat-resistant nanoparticles retain the strength properties of alloys up to at least 450 °C, while most aluminium alloys soften significantly after heating to 250°C.

These activities pursue the fundamental goal of achieving the desired, targeted microstructure and planned properties by optimising the parameters of the transformation or design of the products. In all areas of human activity, new materials are being introduced constantly, and, as a result, alternative product design processes. In the Laboratory for Materials Forming, we follow these trends through research work on a new compounding system, studies of the production of modern polymer composite and hybrid materials using 3D printing, analyses of plastic flow mechanisms in modern engineering materials, and the development of special transformation processes (e.g., ECAP). Studies of material recycling processes and analyses of the impact of technological processes on the environment are also carried out, with the aim of following sustainable development in the field of Materials and Technology Development. MAJOR RESEARCH EQUIPMENT PROCESS 11 ThermoFisher Scientific The experimental system for compounding nano- and microstructural polymer composites and metal glasses enables basic research in the field of the synthesis of polymer composites, metal glasses and metal and ceramic powder mixtures. The modular design of the system offers a study of the influence of process parameters on the microstructure and properties of composites, a study of the geometry of screws on the homogeneity of mixtures, the mechanism of mixing and kneading, the study and measurement of rheological properties of composite melts, the study of the influence of additives (stabilisers, lubricants, antioxidants, UV stabilisers, pigments...) on the properties of melts, the influence of technological parameters on the homogeneity of melts and the influence of crystallisation on the structure and properties of metal glasses. The system also enables research into the recyclability of polymer composite mixtures – polymer alloys. This laboratory extruder is ideal for various types of compounding, such as: 3D filaments, a foil making system, a pellet making device. The device for monitoring processes in materials with the measurement of electrical resistance is designed to monitor the processes of melt crystallisation, and enables continuous and non-destructive monitoring: directional solidification (the rate of solidification front, temperature gradient in liquid), equiaxed solidification (solidification interval, cooling velocity) and heat treatment (the kinetics and mechanisms of phase changes in the solid state in many heat treatments: recrystallisation, normalisation, soft annealing, tempering, cementing, nitriding, high temperature oxidation...). 55 HAAKE MiniJet Pro ThermoFisher Scientific The device for injection moulding of polymer and composite materials is capable of injection moulding of various sample geometries and standard test testers with the help of a piston injection moulding system.

HAAKE MARS ThermoFisher Scientific The rheometer enables the determination of the rheological properties of composite melts, the mechanical properties of composite materials, and the analysis of the impact of manufacturing process parameters on the structure, properties and recyclability of the developed composites. The device can be used to measure viscosity, elasticity and temperature-related mechanical changes in samples. With this type of measurement, we can optimise product development, improve productivity and quality. It is designed to allow the use of all related assemblies, including the head and electronic measuring systems, which can be replaced at will.

UCEM's activities are aimed at connecting materials science with the 59 materialographic preparation of samples, and with the characterisation techniques that electron microscopy at UCEM enables (SEI, BEI, EDX analysis, EBSD analysis, SXES analysis, FIB, etc.), with the aim of identifying microstructural constituents and determining the properties of materials depending on the technological processes of production/treatments. It is also possible to observe in environmental mode, which is used successfully for research in the fields of biology, chemistry and medicine. Support is also provided for the analysis of specific samples that are poorly thermally and electrically conductive, soft (e.g., aerogels), volatile (e.g., vanillins), or liquid (e.g., oil droplets). The use of FIB/SEM ion microscopy also enables the physical processing of individual atomic layers of samples. With the help of knowledge and experience, UCEM offers reliable, high-quality and professionally competent support in the characterisation of materials. Research work in the field of Electron Microscopy is related to acquired research projects and programmes, within which new ways and methods of characterisation are also introduced. The contents of research programmes and projects include the identification and characterisation of microstructural elements, the analysis of the impact of manufacturing technologies on the development of microstructure, and studies of the interdependence between microstructure, properties and technology of material production. MAJOR RESEARCH EQUIPMENT JSM-IT 800 SHL JEOL high-resolution scanning electron microscope FEG SEM with EDX, EBSD and SXES spectrometers JEOL The high-resolution field electron microscope is designed for the observation of microstructural constituents using various detectors (SED-topography, BED-composition or Z- contrast, UHD high-resolution topography, UED-high- resolution composition) in different observation modes (STD, BD, LDF). With the STEM detector, it is possible to analyse transmitted electrons in samples of thickness up to 50 nm. With integrated EDX, EBSD and SXES spectrometers, the system enables qualitative and quantitative microchemical analysis, crystallographic phase analysis, determination of crystal grain orientation, detection of light trace elements, and spectroscopy of the chemical state of atoms in microstructural phases. The system enables accurate microchemical analysis in a very short time at high resolution. The SXES spectrometer, which enables the determination of the energy states of binding electrons or the density of the states of valence electrons, is distinguished by its superior energy resolution (1.2 eV). The microscope is distinguished by high resolution (0.5 nm) at an acceleration voltage of 15 kV, and excellent resolution (0.9 nm) at a very low acceleration voltage of 0.5 kV. It also enables observation at extremely low accelerating voltages – 0.01 kV, which is favourable for observing non-conductive samples (polymeric materials, ceramics, biological preparations). The SIRION 400 NC FEI high-resolution field-emission- emission line electron microscope FEI, equipped with an EDX-analyser is a high-resolution field-emission electron microscope that enables extremely high magnifications and high resolution (1 nm). It is equipped with an EDX spectrometer for qualitative and semi-quantitative microchemical analysis and enables qualitative and semiquantitative microchemical spot and area analysis, qualitative line analysis and surface distribution of elements (mapping). Elements ranging from beryllium to uranium can be analysed. Its good resolution at low accelerating voltage also allows the observation of non-conductive samples and materials containing components with a low atomic number. Samples can be observed in a high or low vacuum (up to 130 Pa). The microscope is equipped with an SED (topographic contrast) and BED (topographic and Z-contrast) detector. In addition, it is possible to analyse transmitted electrons in samples of thickness up to 50 nm with a STEM detector. 60 The QUANTA 200 FEI 3D Environmental Line Electron Microscope with an Ion Gun and Platinum Deposition System is an environmental electron microscope with thermal emission of electrons. The microscope allows you to work at different pressures and at 100% humidity. The environmental mode of operation – ESEM, is suitable for the analysis and characterisation of non-conductive samples (polymeric materials, ceramics, non-conductive surface layers, biological and medical preparations, etc.), and is especially important for the observation of moist, oily and dirty samples, and for the observation of in-situ processes (hydration, dissolution, etc.). In addition to the electron source (electron gun), the microscope is also equipped with an ion source (ion gun), which, in addition to observing the surface, also allows surface treatment and analysis of the microstructure below the surface. Non-standard equipment on the microscope is a platinum deposition system that protects the surface from damage that would occur during ion cutting. COOLING CROSS SECTION POLISHER IB-19520CCP JEOL The CCP device is designed for superior cross-sectional preparation of a sample for observation with a scanning electron microscope. The device is equipped with a TVBA holder, that allows the prepared sample to be transferred in a vacuum to the chamber of the JSM-IT 800 SHL electron microscope in such a way that the sample does not meet the atmosphere after cross-sectional preparation. The CCP also includes a CCA adapter for carbon spraying. Compared with conventional mechanical polishing, CCP creates a very uniform cross-section without milling defects. The device is also useful for the preparation of cross- sections of heat-sensitive materials. With the option of the intermittent milling of samples (On-OFF-ON mode) cooled with liquid nitrogen (down to -120 °C), the concentration is reduced of defects on the surface of polished samples that may arise due to the influence of heat. CRYO ION SLICER ONE-09090CIS JEOL An apparatus for the automatic preparation of thin wafers for observation by means of a transmission electron microscope (TEM). A beam of Ar ions is used for the preparation of wafers, with the possibility of cooling the sample carrier down to - 120 °C.

Precise surgical planning is common in all medical fields when it comes to invasive procedures on the human body, regardless of medical specialisation. Surgical planning is always based on diagnostic data which must be collected, visualised and evaluated in a way that corresponds to the final goal. To understand the general needs of surgical planning, the Additive Manufacturing Laboratory has studied and analysed several surgical cases over the last 10 years. In all cases, the diagnostic data was converted into three-dimensional models which were later used for planning and, after confirming the planned therapeutic parameters, transformed into a tangible surgical device using additive manufacturing. The three-dimensional planning process has many advantages but requires some skills that are not common among physicians. The results of our research summarise the specifics of three-dimensional planning and provide guidelines for the wider use of patient-friendly medical devices made with additive manufacturing technologies.

MOST IMPORTANT RESEARCH ACHIEVEMENT The development of two-level cyber-physical machining systems for monitoring the condition of the cutting tool, the quality of the treated surface, energy consumption and clamping stability. A cloud-based system structure is created for real-time monitoring of the tool's condition, by detecting the size of cutting chips in face milling. The system is designed to connect an IoT (Internet of Things) platform for monitoring the condition of tools in a private cloud with a machine tool and an optical system in the tool shop. The optical system takes care of capturing and transmitting the cutting chip size signals to the IoT application, where they are used as an indicator to determine the condition of the tool and the quality of the surface. The IoT cloud platform uses real-time Internet analytics services to monitor the surface quality and process correction in material processing, 77 where sudden wear and frequent tool damage occur. Analytical services in the form of Internet applications can be shared with other geographically distributed production systems in the machining shop. Artificial Intelligence, integrated into the platform with sample recognition capability, monitors the surface quality status by identifying the current trend of the calculated cutting force, and protects the tool from excessive loads by correcting the process parameters.

MOST IMPORTANT RESEARCH ACHIEVEMENT Analysis of the processing capacity of aluminium foams by cutting and incremental transformation processes. Mechanical processing tests were performed of turning, milling, drilling and single-point incremental forming of aluminium foam samples. The influence of machining parameters on the porosity of the treated surface was determined with the help of the method of responsive surfaces. From the test results, it was found that the number of revolutions has the maximum and the feed velocity the least effect on the reduction of surface porosity. Incremental transformation of aluminium foam Pressure Diagram of Foamtech Aluminium Foam Sample Testing The compressive properties of the treated samples, whose surface porosity was reduced due to surface deformation, increased significantly. It has been established that the thickness of the deformed surface depends on the transforming properties of the material of aluminium foams. It has been established and proven that elements manufactured by material removal processes can increase compressive strength and reduce notching effects by subsequent transformation processes such as incremental transformation and friction rolling. Such a combination of machining processes, which can be carried out on the same machine, makes sense to use in small-scale production of products. PUBLICATIONS 1.

Prof. Julija Volmajer Valh E-mail: julija.volmajer@um.si Tel.: +386 2 220 7897 Web: https://www.fs.um.si/laboratorij-za-kemijo-in-okoljevarstvo/ The basic activities of the laboratory are educational and research work in the fields of chemistry, organic chemistry, analytical methods, recycling and the study of the negative impact of textile and plastic waste on the environment. The laboratory performs spectroscopic characterisation of ATR FTIR, RAMAN UV-/VIS analyses and spectroscopic characterisations at the micro-level with FTIR microscopy. The general characterisation of waters, which includes the determination of various parameters such as hardness, pH value, electrical conductivity, turbidity, colouring, COD, BPK and TOC values as well as the determination of heavy volatile lipophilic substances 106 (TLS) and toxicity test using the Vibrio Fisheri method, is also part of the laboratory's range of services. In the field of research, the group focuses on the development of new technologies for wastewater treatment using advanced oxidation processes, and on the chemical and thermomechanical recycling of textile and plastic materials, with the aim of obtaining new secondary raw materials. MAJOR RESEARCH EQUIPMENT NANOCOLOR Macherey-Nagel The device consists of a thermoblock and a measuring unit. With the help of prefabricated reagent kits, it enables standard tests for water analysis to be carried out based based on photometric analysis. The manufacturer offers more than 500 kits. The device enables the measurement of UV/VIS values at selected wavelengths. Luminometer Dr. Lange Vibrio fischeri Bacteria Toxicity Determinant. Exposure to toxic substances in water leads to an inhibition of the bioluminescence of Vibrio fischeri bacteria, which is measured with a luminometer before exposure to the test substance and after a certain incubation time. The decrease in light intensity is inversely proportional to the toxicity of the test substance.

We focus primarily on advanced functionalisation and characterisation of polymeric materials, with special attention paid to textile materials and composites. The aim of our research is to develop smart and (multi)functional textiles, nanofibres and polymer composites for various purposes, such as bioactive packaging, medical and engineering applications. In doing so, we are starting from the horizontal integration of nano- and biotechnologies and are developing a (new) concept of closed-loop waste and environmentally friendly materials. We have expert knowledge and analytical tools for determining the physicochemical properties of polymer materials, and we focus on the analysis of surfaces and surface phenomena, and on an in-depth understanding of the interactions on the intermediate surfaces between solid and liquid and solid and gaseous. MAJOR RESEARCH EQUIPMENT LITESIZER 500 Anton Paar The Litesizer 500 is an excellent choice for determining the properties of nano- and microparticles in dispersions and solutions. The particle size is determined by the dynamic method (DLS) and the zeta potential by the electrophoretic light scattering method (ELS). Titrators T70, DL53, DL28 Mettler Toledo Titration techniques: potentiometric, conductometric, and polyelectrolyte titrations are used commonly to determine the charge of charged monomers and polymers in solutions or suspensions (fibres, cellulose, foils, membranes, etc.) and the type of dissociating and surface accessible groups, the dissociation constant (pK values) in solvents of different polarities. SurPASS 3 Anton Par The SurPASS 3 instrument is used to analyse the zeta potential of solids of almost any shape and size, such as fibres, foils, plates, textiles, powders or granules. The principle of zeta potential analysis with the SurPASS 3 instrument is based on the flow potential and flow current method. Adsorption experiments can also be done with this machine. 110 Quartz Microbalance with Dissipation Biolin Scientific A quartz microbalance with dissipation is a device that analyses surface phenomena, including thin film formation, interactions and reactions, at the nanoscale and in real time. It can be used to monitor the adsorption/desorption behaviour in real time at the solid-liquid intermediate phase. 3D BIO-printer GeSiM BioScaffolder GeSiM Bioinstruments and Microfluids Bioscaffolder is a unique 3D bioprinter that allows simultaneous printing of cell carriers and living cells. It uses two different technologies, pneumatic extrusion and piezoelectric printing. Nanospider NS 500 Elmarco The nano-fronting device enables the so-called needle-free formation of nanofibres from a viscous polymer solution using a strong electrostatic field. This enables the production of nanofibrous structures (coprene), useful e.g., in medicine as wound dressings or air filters, etc. SEM with EDXS- SUPRA 35 VP Carl Zeiss EDXS spectrometer Ultim Max 100 Oxford, VB A line electron microscope (FESEM) for the analysis of the morphology, topography and chemical composition characteristics of many types of materials.

The research work focuses on the planning and constructing of linear and flat textiles for different applications (clothing, interiors and technical applications). We also work on the modernising flat textile production processes, particularly the digitalisation of weaving preparation. Important thematic areas of our research include mechanical and physical properties planning of classical and technical textiles, auxetic textiles and other flexible engineering materials, 118 such as foams, rubbers, gels, composites and the like. In addition, we carry out porosity analysis of textile and other engineering materials and functional property modelling of textiles, as well as updating the process of sampling and constructing of dobby and jacquard fabrics. MAJOR RESEARCH EQUIPMENT Force Testing System H10KT Tinius Olsen. The system enables the measurement of the mechanical properties of linear (yarns, threads, tapes, ropes) and flat (woven fabrics, knitted fabrics, non-woven fabrics, compound fabrics) textiles and non-textile materials, such as paper, leather, plastic, rubber, composites, gels, etc. The system currently enables the analysis of the behaviour of materials under tensile and compressive loads up to 50 N, 1000 N and higher loads, up to 10 kN, making it particularly suitable for testing technical materials such as conveyor belts, belts, laminates, geotextiles, etc. in accordance with the relevant Standards. Mercury Porosimeter Pascal The 140/440 instrument is used to analyse the porosity of solid materials. It operates at lower Hg injection pressures (up to 400 kPa), and is suitable for measuring the porosity of macro and mesoporous solids with pore size classes ranging from 900 μm to 3.8 μm, or at higher Hg injection pressures (up to 400 MPa), and is suitable for measuring the porosity of microporous solids with pores in the pore size class from 5 μm to 3.6 nm. Image Analysis System Lucia Optoteam The system enables the capture, analysis and archiving of microscopic images of test samples of linear and flat textiles. It is suitable for both translucent and opaque samples. It enables the capture and processing of image information (measurements of details in the image (length, width, area, circumference...), determination of the characteristics of textile materials (systematics of effects, structure, defects), determination of the shape and distribution of pores in flat textiles, determination of the type of defects in yarns/threads and flat textiles. SERVICE OFFER AND SUPPORT TO THE ECONOMY  Analysis of the behaviour of linear and flat textiles and other materials (plastics, rubber, paper, leather, composites, gels, etc.) under tensile and compressive loads, according to the protocols in respect to various Standards.

MOST IMPORTANT RESEARCH ACHIEVEMENT Development of functional non-woven fabrics with auxetic properties. Using the geometry of rotating square cells, we have developed modified classic non-woven textiles used in the footwear industry with auxetic properties. Due to their auxetics, such materials are easier to shape or model into various forms, thus enabling a better fit to the mould, while, at the same time, they do not shrink under tensile loads but expand. This allows for more comfortable footwear, because, for example, in the case of a swollen foot, the footwear "expands" in proportion to the size of the swelling of the instep. PUBLICATIONS 1.

CEEPUS NETWORK SI-0217 ARS-TECHNE: CREATIVE DESIGN AND INNOVATION is the first network at the Faculty of Mechanical Engineering at the University of Maribor, founded in 1997 as the Slovenian network CEEPUS SI-0007. It is the first network that connected faculties in the field of textile and clothing engineering and promotes the mobility of students and professors between the participating countries. The network has been operating successfully since 1997, when four universities joined the network as part of the programme Modelling of Credits Transfer System in Textile Higher Education. Today, the network comprises 14 partner institutions and is often presented as an example of good practice. The established network has played an important role in the field of textile education, as it was the first to open the door to an active Central European network of partner institutions and has led to active multilateral cooperation through its activities, which is also reflected in the successfully organised international CEEPUS Winter Schools Design Week, which has further strengthened this cooperation. In 2018, the SI-0217 Ars-Techne: Creative Design and Innovation network received the Apple of Quality 2018, a national award from the Ministry of Education, Science and Sport, and CMEPIUS, that annually rewards the most outstanding stories of international cooperation, while in 2019, the coordinator of network received the Ministers' Prize of Excellence 2019 for outstanding achievements. In 2024, the network coordinator received the Diploma for his outstanding work in the Slovenian network Ars-Techne: Creative Design and Innovation. INTERNATIONAL CEEPUS WINTER SCHOOL DESIGN WEEK is a visible and recognisable activity of the network. The beginnings of the international CEEPUS Winter School Design Week date back to 2012, when the concept of the Winter School was designed, which covers the spectrum of modern engineering design of clothing and/or other textile forms in the broadest sense of connecting scientific and artistic disciplines. The motto of these is human-centric design and innovation:  Design as a driver of people-centred innovation, 2nd international CEEPUS Winter School Design Week 2013, Maribor, 20-26 October 2013.  New challenges for the innovative solutions, 3rd international CEEPUS Winter School Design Week 2014, Maribor, 19-25 October 2014. 129  New challenges - new ideas - new solutions, 4th international CEEPUS Winter School Design Week 2015, Maribor, 18-24 October 2015.  Design in the light of light - new challenges ‒ new solutions, 5th international CEEPUS Winter School Design Week 2016, Maribor, 16-22 October 2016.  Design & Transdisciplinarity - New Challenges, 6th International CEEPUS Winter School Design Week 2017, 15-21 October 2017.  Smart Design, Science & Technology - New Challenges, 7th International CEEPUS Winter School Design Week 2022, Maribor, 16-22 October 2022.  Transdisciplinary: Design, Science & Technology - the basis for the development of people- and environmentally friendly solutions, 8th international CEEPUS Winter School Week 2023, Maribor, 15-21 October 2023.  Transdisciplinary: Design, Science & Technology - the basis for the development of people- and environmentally friendly solutions, 9th international CEEPUS Winter School Design Week 2024, Maribor, 20-26 October 2024.

In addition, the members of the laboratory are active in research in the fields of atomic physics, biophysics and soft matter physics, and didactics of physics. In atomic physics, using X-ray absorption and fluorescence methods, we study multi-electron photoexcitations in an atom and analyse the close neighbourhood of the atom. Most of the research work is done at synchrotrons in Hamburg, Grenoble and Trieste. The EXAFS and XANES measurement techniques enable the precise determination of the valence and atomic environment of the selected element, the work is done in collaboration with research groups in the field of materials and chemistry. The research in biophysics focuses on biologically important molecules, specifically, guanosine and short, guanine-rich DNA sequences. The self-assembly of these molecules in solutions is studied by light scattering and UV-VIS spectrometry, and their organisation on solid surfaces by an atomic force microscope. In soft matter physics, liquid crystalline phases formed by condensed solutions of short, guanine-rich DNA sequences are studied using optical polarisation microscopy. Experimental work in soft matter physics and biophysics is carried out in cooperation with the Jožef Stefan Institute in Ljubljana. In the field of didactics, together with students, we explore new thematic and methodological approaches to teaching physical problems.

In graph theory, which has a wide range of applications in physics, chemistry, biology and other sciences, we study the modelling of relationships and processes. We study different graph invartiants, such as the chromatic number, the domination number, connectivity and hamiltonicity of graphs. These invariants are studied for various classes of graphs, such as planar graphs or graph products. In the second part of the research work, we examine identities with additive mappings, which turn out to be derivations, Jordan *-derivations, or centralizers under certain conditions for rings. We also deal with solving functional equations on operator algebras, where the operators act on Banach or Hilbert spaces. COOPERATION WITH RESEARCH AND OTHER INSTITUTIONS  University of Ljubljana, Ljubljana, Slovenia  Institute of Mathematics, Physics and Mechanics, Ljubljana, Slovenia  University of Kragujevac, Kragujevac, Serbia  University of Montenegro, Podgorica, Montenegro  Vanderbilt University, Nashville, USA MOST IMPORTANT RESEARCH ACHIEVEMENT We investigate plane triangulations and their properties. We are particularly interested in the dominantion number of planar triangulations, for which the well-known Matheson-Tarjan conjecture asserts that any planar triangulation on n-vertices has a dominating set of size not more than n/4. We introduce a class of planar graphs called weak near-triangulations. It turns out that the class of weak near-triangulations is closed under certain graph operations, and, by means of these operations, we proved that each weak near-triangulation has a dominanting set of size at most 17n/53. 133 The paper was published in the Journal of Combinatorial Theory Series B.
