Electron irradiation effects on the nucleation and growth of Au nanoparticles in silicon nitride membranes
(2017) [Journal article]The formation of Au nanoparticles (NPs) in Auþ ion-implanted silicon nitride thin films and membranes was investigated as a function of post-implantation thermal treatments or room temperature electron irradiation at ... -
Eucalyptus oil-mediated synthesis of gold nanoparticles
(2018) [Journal article]The search for efficient methods for the synthesis of metal nanoparticles has been widely explored. Within this context, the use of biological materials such as plants, algae, bacteria and fungi has been reported to various ... -
Gold nanoparticles inhibit steroid-insensitive asthma in mice preserving histone deacetylase 2 and NRF2 pathways
(2022) [Journal article]Background: Gold nanoparticles (AuNPs) can inhibit pivotal pathological changes in experimental asthma, but their effect on steroid-insensitive asthma is unclear. The current study assessed the effectiveness of nebulized ... -
Growth of TiO2 nanotube arrays with simultaneous Au nanoparticles impregnation: photocatalysts for hydrogen production
(2010) [Journal article]Um novo método para a fabricação de nanotubos (NTs) de TiO2 organizados e impregnados com nanopartículas (NPs) de ouro foi desenvolvido, e as propriedades estruturais, morfológicas e ópticas dos NTs obtidos foram investigadas. ... -
Interface dependent plasmon induced enhancement in dye-sensitized solar cells using gold nanoparticles
(2015) [Journal article]We report a study on plasmon-induced photoelectrochemistry from gold nanoparticles incorporated in dye-sensitized solar cells, assembled in two different configurations: TiO2/Aunanop/Dye and TiO2/Dye/Aunanop. Although the ... -
Magnesium surface enrichment of CoFe2O4 magnetic nanoparticles immobilized with gold : reusable catalysts for green oxidation of benzyl alcohol
(2018) [Journal article]Gold nanoparticles have shown excellent activity for selective oxidation of alcohols; such catalytic systems are highly dependent on the initial activation of the substrates, which must occur on the catalyst surface in ... -
SPR biosensors based on gold and silver nanoparticle multilayer films
(2014) [Journal article]Filmes em multicamadas de nanopartículas de ouro e prata foram utilizados para o desenvolvimento de um sensor plasmônico para detecção de ligações entre moléculas orgânicas e/ou com atividade biológicas. A sensibilidade a ...
