Carbon nitrides are polymeric compounds with a C3N4 stoichiometric ratio and formed by sp2 nitrogen bonds. Most of the works in the literature uses polymeric carbon nitride as a catalyst for application in organic reactions, ...

As propriedades mecânicas da liga 'TI'-13'NB'-13'ZR' (TNZ) são modificadas de maneira significativa com a presença de elementos intersticiais tais como oxigênio, carbono, nitrogênio e hidrogênio, principalmente suas ...

Tailoring the properties of a material for a target application often depends on combining features of different components. To effectively arrange these components in a material, several methods have been developed to ...

The slow kinetics of the oxygen reduction reaction is the main cause of the severe performance losses of fuel cell cathode. Pt is the most active pure metal to catalyze this reaction. However, because of their limited ...

This work describes studies on the underpotential deposition (UPD) of selenium, zinc, as well for Zn/Se systems deposited on polycrystalline Pt electrodes in acid solutions. The effects of Zn presence in the Se dissolution ...

A fim de desenvolver novos desinfetantes capazes de desativar a longo prazo os agentes patogênicos, incluindo o coronavírus (SARS-CoV-2), presentes em múltiplas superfícies, o presente trabalho mostra um método de síntese ...

The microwave-assisted hydrothermal method was implemented in the synthesis of alkaline earth titanates under ABO3 stoichiometric known as perovskites, being efficient and innovative. For that, OH- groups played an important ...
