20.500.12556/RUL-187239 Nadaljnja rast srebrnih nanospiral Further growth of silver nanospirals Srebrne nanostrukture imajo zaradi svojih značilnih optičnih lastnosti in možnosti nadzorovanja njihove morfologije velik potencial za uporabo na različnih področjih. Srebrne nanospirale so anizotropne nanostrukture, katerih optične lastnosti so močno odvisne od njihove oblike, velikosti in površinske sestave. Na njihovo nastajanje in nadaljno rast vplivajo reakcijski pogoji ter ligandi, ki se vežejo na površino srebrnih nanostruktur in usmerjajo njihovo rast. V okviru diplomskega dela smo srebrne nanospirale pripravljali ob prisotnosti 3-merkaptopropionske kisline (MPA) ter ugotavljali, pri katerem molskem razmerju MPA/Ag nastanejo nanospirale. To nam je uspelo doseči pri molskih razmerjih 0,01 in 0,015. Nato smo preučevali njihovo nadaljnjo rast ob dodatku različnih količin srebrnih nanodelcev ter v prisotnosti in odsotnosti MPA. Pri izbranih eksperimentalnih pogojih nadaljnje spiralne rasti ni bilo mogoče potrditi. Silver nanostructures have considerable potential for applications in various fields due to their characteristics optical and the possibility of controlling their morphology. Silver nanospirals are anisotropic nanostructures whose optical properties strongly depend on their shape, size and surface composition. Their formation and further growth are influenced by reaction conditions and ligands that bind to the surface of the nanostructures and direct their growth. In this thesis, silver nanospirals were prepared in the presence of 3-mercaptopropionic acid (MPA) and determined at which molar ratio of MPA/Ag nanospirals are formed. We managed to achieve this at molar ratios of 0,01 and 0,015. Then we studied their further growth upon the addition of different amounts of silver nanoparticles and in the presence and absence of MPA. Under the selected experimental conditions, further spiral growth could not be confirmed. srebrne nanospirale srebrni nanodelci nadaljnja rast MPA SEM silver nanospirals silver nanoparticles further growth MPA SEM true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-09 12:45:01 2026-09-09 12:45:03 2026-10-26 13:12:03 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 26219 302519299 Nemanic_Anze_-_Nadaljnja_rast_srebrnih_nanospiral.pdf Nemanic_Anze_-_Nadaljnja_rast_srebrnih_nanospiral.pdf 1 3362EC1CDDD762307364861520FC33B2 7760970428f24c04b2d67033590a93f2d94f40b089d992c86e288a46371fbe1b 7d358f14-ac3b-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246763 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
