Abstract:

Dentre os processos de oxidação avançados (POAs), a fotocatálise heterogênea mediada por óxidos semicondutores como ZnO e TiO2 tem sido muito efetiva na remoção de cor com baixo nível de contaminante. As caracterizações estruturais e morfológicas dos fotocatalisadores utilizados neste processo são importantes, pois o conhecimento da composição da camada superficial do sólido, viabiliza a compreensão da capacidade de adsorção e de fotocatálise. Este trabalho tem como objetivo sintetizar e caracterizar nanocristais de ZnO e Ag2O-ZnO obtidos em diferentes temperaturas e aplicar na fotocatálise do

Abstract:

La croissance rapide de la population ainsi que l'industrialisation ont suscité des inquiétudes majeures quant à la disponibilité de l'énergie et à la pollution de l'environnement. La résolution de ces problèmes est au cœur de nombreuses recherches à l'échelle mondiale. L'énergie solaire, en tant que source d'énergie propre et pratiquement inépuisable, devrait être efficacement exploitée, notamment via des processus photocatalytiques, pour améliorer la dépollution environnementale. Les nanomatériaux hybrides, tels que ZnO/métal noble et ZnO/oxydes métalliques, se positionnent comme des candida

Abstract:

One-dimensional nanomaterials (NMs) have become the focus of intensive research due to their unique physicochemical properties and their application in the fabrication of nanoscale devices. Silver (Ag) and zinc oxide (ZnO) nanowires (NWs) are considered as potential building blocks for the next generation of optical, electronic and sensing devices. However, there is currently limited information on human health effects from Ag and ZnO NW exposures, but concerns have been raised about a potentially greater toxicity compared to their non-fibrous counterparts. Inhalation of Ag and ZnO NWs represe

Останнім часом виготовлення елементів побуту переходить від адитивного методу виробництва до формування цілісного об’єкта методом 3D друку. Це пов’язано з тим, що цей метод дає змогу здешевити і пришвидшити виробництво, а в подальшому перенести виготовлення нескладних предметів побуту безпосередньо в людські домівки. Технологія друку чорнилами на основі наночастинок металів та напівпровідників дає змогу швидко та дешево створювати електричну розводку і напівпровідникові елементи приладів сенсорики, прозорої електроніки та геліоенергетики.
