20.500.12556/RUL-158985 Analiza hitrosti pretvarjanja srebrovih nanojeder v mikroploščice Analysis of the rate of conversion of silver nanocores to microplates Srebrove nanoploščice so posebna morfologija srebra, kot posledica defektov v kristalni strukturi, za katere je značilna oblika trikotnika ali šestkotnika in izredno tanka debelina. Kemijska pretvorba najpogosteje poteka z dodatkom H2O2. Tekom diplomskega dela sem sledil reakciji preko absorbance in posnetkov z elektronsko vrstično mikroskopijo (SEM), na osnovi česar sem opisal odvisnost deleža pretvorbe in morfologije nanoploščic v odvisnosti od dodane količine vodikovega peroksida in naredil računalniški model uporabljenega reaktorja. Reakcija AgNPjev z vodikovim peroksidom v pretočnem reaktorju z membrano poteka lokalizirano na steni membrane. Edina plasmonična barva, ki jo lahko vidimo je modra preden se razbarva in izgine v IR spekter. Silver nanoplates are a special morphology of silver, as a result of defects in the crystal structure, which are characterized by a triangular or hexagonal shape and an extremely thin thickness. The chemical conversion most often takes place with the addition of H2O2. During the thesis, I followed the reaction through absorbance and scanning electron microscopy (SEM), based on which I described the dependence of the conversion rate and the morphology of the nanoplates depending on the added amount of hydrogen peroxide and wrote a computer model of the used reactor. Reaction with AgNPs and hydrogen peroxide in a plug flow reactor with a membrane is localized on the wall of the membrane. The only plasmonic color that can be observed is blue before it decolors as it moves to the IR spectre. srebrovi nanodelci srebrove nanoploščice pretočni reaktor Python model semipermeabilna membrana kinetika reakcije silver nanoparticles silver nanoplates plug flow reactor Python model semipermeable membrane reaction kinetics true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2024-06-26 11:05:00 2024-06-26 11:05:04 2024-07-24 10:21:26 0000-00-00 00:00:00 2024 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 23005 202642691 Jelen_Kalvin_-_Analiza_hitrosti_pretvarjanja_srebrovih_nanojeder_v_mikroploscice.pdf Jelen_Kalvin_-_Analiza_hitrosti_pretvarjanja_srebrovih_nanojeder_v_mikroploscice.pdf 1 54C78B1B89C7B8097B3B31D444F55636 8c69456ee537826db3232855f22bcbd9de912cce9a1ef55b14ab7b59f96c0227 2e14e6f3-339b-11ef-8fa5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=186729 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
