We report a simple yet highly efficient chemical motor that can be controlled with visible light. The motor made from a noble metal and doped silicon acts as a pump, which is driven through a light-activated catalytic reaction process. We show that the actuation is based on electro-osmosis with the electric field generated by chemical reactions at the metal and silicon surfaces, whereas the con...

Dopamine  (DA)  and  uric  acid  (UA)  are  two  of  important bimolecular widely  circulated  in  body blood. Therefore, development of simple and rapid methods for simultaneous determination of them in  routine  analysis  has  a  great  significance  for  many  researchers. Therefore,  for  the  first  time, nanocomposite  of  graphene  (Gr)LaMnO3has  been  utilized  to  fabricate  the  new  ...

Abstract Catalytic conversion of CO 2 into chemicals and fuels is a viable method to reduce carbon emissions achieve neutrality. Through thermal catalysis, electrocatalysis, photo(electro)catalysis, can be converted wide range valuable products, including CO, formic acid, methanol, methane, ethanol, acetic propanol, light olefins, aromatics, gasoline, as well fine chemicals. In this mini-review...

In this research, we reported a novel modified carbon ceramic electrode (CCE) using Ni/Al Layered double hydroxide as modifier was fabricated by sol-gel technique. The Ni/Al Layered double hydroxide modified sol gel derived carbon ceramic (Ni/Al LDH-SGD-CC) electrode was used for electrocatalytic oxidation of acetaldehyde. The oxidation of acetaldehyde happens at the potential where Ni (III) sp...

In this paper, density functional theory (DFT) calculations are performed to analyze the electrochemical water-splitting process producing molecular oxygen (O2) and hydrogen (H2). We investigate the trends in the electro-catalytic properties of (110) surfaces of three rutile-type oxides (RuO2, IrO2, and TiO2). The two first of these oxide anodes show lower O2-evolving over-potentials than metal...
