The experimental investigations of the (USP) method were performed with an ultrasonic source of 0.8 MHz and 2.5 MHz, acting on the water solution of HAuCl4 forming aerosols with micron-sized and nanosized droplets. The results of the investigation show that the final shape and size of the Au particles depend on the characteristics of the solution and the frequency of the ultrasound. The second step of synthesizing the Au nanoparticles includes the subsequent thermal decomposition of the aerosol droplets in a hydrogen atmosphere between 260°C and 500°C. The investigations showed that the Au nanoparticles prepared in this way are smaller and more homogeneous</dc:description><dc:description xml:lang="sl">Zlate nanodelce različnih velikosti in oblik (sferični, cilindrični, trikotni in okrogli) smo pripravili s sintezo zlata z uporabo ultrazvočne razpršilne pirolize (USP) in redukcije. Eksperimentalne raziskave USP-metode so bile izvedene z ultrazvočnim izvirom s frekvenco med 0,8 MHz in 2,5 MHz z delovanjem na vodno raztopino HAuCl4, kjer je prišlo do formiranja aerosolov z mikro- in nanovelikostjo kapljic. Rezultati preiskav kažejo, da je oblika in velikost nastalih Au-delcev odvisna od karakteristik raztopine in od frekvence ultrazvoka. Drugi proces sinteze Au-nanodelcev je vključeval kasnejšo toplotno dekompozicijo kapljic aerosola. Izveden je bil v vodikovi atmosferi med 260°C in 500°C. Preiskave so pokazale, da so tako izdelani Au-delci bolj homogeni in manjši</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-YFGUPNST"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-YFGUPNST" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-YFGUPNST/c93f308e-a3fa-4d07-aa0a-33c474343f75/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:intermediateProvider xml:lang="en">National and University Library of Slovenia</edm:intermediateProvider><edm:dataProvider xml:lang="sl">Inštitut za kovinske materiale in tehnologije</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-YFGUPNST/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-YFGUPNST" /></ore:Aggregation></rdf:RDF>
