O objetivo do presente estudo foi avaliar a toxidade aguda de nanopartículas de prata em tambaqui Colossoma Macropomum. Para isso, foi realizada a síntese da nanopartícula de prata com 300mg de nitrato de prata dissolvido em 5 mL de água destilada. Em seguida, esta solução foi adicionada outra solução contendo 95mL de álcool polivinílico sob agitaç...
Suétone est un auteur latin des Ier-IIe siècles de notre ère, aujourd’hui connu pour son œuvre de biographe. Cependant, ce n’est en vérité qu’une maigre partie de son œuvre complète ; des témoignages d’auteurs postérieurs nous apprennent qu’il était également l’auteur d’un grand nombre d’ouvrages aux sujets très variés, dont il ne nous reste que qu...
Dissertação (mestrado) - Universidade Federal de Santa Catarina, Centro Tecnológico, Programa de Pós-Graduação em Engenharia Química, Florianópolis, 2021. / Os carbon dots (CDs) são nanopartículas com grande potencial em aplicações ambientais, biomédicas e analíticas, com destaque para sua aplicação como sensores de íons metálicos. Contudo, desafio...
Abstract : This work assessed the photocatalytic activity of TiO2 modified with lanthanum and silver (Ag-La/TiO2) in the decolorization of methylene blue and in the degradation of propranolol hydrochloride.The obtained photocatalysts were characterized by XRD, FE-SEM, EDX, TEM, BET, DRS and PL techniques. Moreover, a particle analyzer assessed the ...
The aim of this study was to evaluate the antimicrobial/antibiofilm activities and the cell viability of silver nanoparticles (AgNPs) obtained by a ‘green’ synthesis associated or not to β-calcium glycerophosphate (CaGP) against Streptococcus mutans and Candida species (reference strains and oral clinical isolates including azole-resistant strains)...
Materiais opticamente ativos tem atraído atenção visando aplicações tecnológicas em razão da possibilidade de controlar absorção, reflexão e transmissão. Dentre esses materiais incluem-se os materiais fotocrômicos, que são conhecidos por apresentar mudança de cor sob exposição de radiação eletromagnética (como no caso da radiação ultravioleta (UV))...
Abstract : In this work we studied the influence of organic molecules, principally Dithiothreitol molecule (DTT), in the electrical and mechanical properties of the isotropic conductive adhesives (ICA). The ICAs were filled with commercial silver micro flakes (AgC) or submicron silver particles from waste jewelry (AgR). The results showed that DTT ...
The present work reviewed in the literature studies of phythosynthesis of silver nanoparticles (AgNP) between 2006 and 2017, highlighting the variety of plants used to and how they can influence the characacteristics and properties of AgNP. This work also evaluated the influence of temperature (25, 50, 70 and 95°C) and concentration of peel extract...
