20.500.12556/DKUM-86535 Melting point of dried gold nanoparticles prepared with ultrasonic spray pyrolysis and lyophilisation A coupled process of ultrasonic spray pyrolysis and lyophilisation was used for the synthesis of dried gold nanoparticles. Two methods were applied for determining their melting temperature: uniaxial microcompression and differential scanning calorimetry (DSC) analysis. Uniaxial microcompression resulted in sintering of the dried gold nanoparticles at room temperature with an activation energy of 26–32.5 J/g, which made it impossible to evaluate their melting point. Using DSC, the melting point of the dried gold nanoparticles was measured to be around 1064.3°C, which is close to pure gold. The reason for the absence of a melting point depression in dried gold nanoparticles was their exothermic sintering between 712 and 908.1°C. gold nanoparticles melting point ultrasonic spray pyrolysis characterisation zlati nanodelci tališče ultrazvočna razpršilna piroliza karakterizacija true false true De Gruyter https://www.degruyter.com/document/doi/10.1515/ntrev-2022-0568/html Angleški jezik Slovenski jezik https://www.degruyter.com/ Published source must be acknowledged Must link to journal homepage with DOI Članek v reviji 2023-12-08 09:15:47 2023-12-08 09:15:47 2024-04-05 14:20:08 0000-00-00 00:00:00 2023 0 0 12 str. iss. 1 Vol. 12 July 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 2023-04-07 2023-06-12 2023-07-10 669.2/.8:620.3 158645507 10.1515/ntrev-2022-0568 2191-9097 10.1515_ntrev-2022-0568_(1).pdf 10.1515_ntrev-2022-0568_(1).pdf 1 81FF6B867DD4ADC0C96E482BB24ED7B8 c290d1900b836e9b1aaec6288d7abb2fc22a97a1a3183baa1a2cd51d977cbd2b 2fed310e-95a7-11ee-a137-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174750 https://www.degruyter.com/document/doi/10.1515/ntrev-2022-0568/html 0 7406c1da-95aa-11ee-a137-00155d000105 https://dk.um.si/Dokument.php?lang=slv&id=174752 Fakulteta za strojništvo 0 0 0
