Células solares sensibilizadas surgiram como uma possibilidade de superar o limite fotoconversão termodinâmica além da redução custos. Neste estudo é proposta cossensibilização, combinando um corante natural extraído do jenipapo amazônico com pontos quânticos CdS. Os resultados observados pelas análises absorção no UV-Vis e caracterizações fotoeletroquímicas permitiram garantir potencial cossensibilização por pigmento ponto quântico fotoanodos. Esses fotoanodos foram testados em células...
Flexible substrates are being sought after as an alternative to meet the demand of integrated circuit industry. Polyimide (PI) is a promising option due its excellent mechanical and electrical properties. This study uses PI substrate test different copper (Cu) seed deposition processes via sputtering. Results showed that time, pressure, power have greatest impact on film thickness sheet resistance. Reliability was evaluated through peel tape tests deposition, temperature cycling,...
O presente trabalho teve como objetivo avaliar a estabilidade do óleo da semente de inajá (Maximiliana maripa) sob duas condições distintas: refrigerado e protegido luz (RAL) temperatura ambiente (TLA). Para tanto, foram utilizados parâmetros físico-químicos os índices acidez, peróxidos iodo, quais determinados segundo as metodologias descritas nas Normas Analíticas pelo Instituto Adolfo Lutz (2008). método estatístico utilizado foi análise variância. Os resultados revelaram que ao longo...
