An Atomic Redistribution Study of the 440°C Ageing Kinetics in Maraging-300 Steel
Silva,Jean Jefferson Moraes da; Vasconcelos,Igor Frota de; Silva,Francisco Iran Sousa da; Ribeiro,Thiago Soares; Abreu,Hamilton Ferreira Gomes deMӧssbauer spectroscopy, X-ray diffraction and hardness measurements were used to investigate the atomic redistribution and phase transformation of solution-treated and 440°C aged Maraging-300 steel specimens. The ageing temperature that resulted in the best mechanical properties in this steel was 480ºC. At 440ºC, the formation of the precipitates that assure excellent mechanical properties of the maraging steel...
Flexible, Large-Area Organic Solar Cells With Improved Performance Through Inco...
Pereira,Maurício de Sousa; Lima,Francisco Anderson de Sousa; Almeida,Rodrigo Queiros de; Martins,Juliana Luiza da Silva; Bagnis,DiegoCobalt ferrite (CoFe2O4) nanoparticles (NPs), with an average diameter of about 4-10 nm, were produced by the proteic sol-gel method and successfully doped into the active layer of poly(3-hexylthiophene-2,5-diyl) (P3HT):[6,6]-phenyl-C61-butyric acid methyl ester (PCBM) organic solar cells. Pristine and CoFe2O4 NPs-doped blends of P3HT:PCBM were dispersed in a mixture of o-xylene:tetralin (1 mg/mL) based non-hal...
Use of SnOx:F in the Recycling of Silicon Solar Cells
Lima,Francisco Marcone; Alves,Jean Faber Araújo; Maia Júnior,Paulo Herbert França; Martins,Felipe Mota; Teixeira,Edwalder SilvaAmongst the many parts of a silicon cells photovoltaic module, silicon is the most important and expensive constituent. Thus, research on silicon recycling from damaged cells can lead to economic and environmental benefits. In this work, the broken silicon cells were tailored to function along with the fluorine-doped tin oxide as the transparent electric conductors. The broken silicon cells were analyzed by the...
