In this work, a new mechanism is proposed for the redox of hypophosphorous acid catalyzed by a nickel cluster through a combined study of density functional theory (DFT) calculations and electrochemical impedance spectroscopy (EIS) measurements. The DFT results indicate that the concentration of OH is a crucial species to control the oxidation and reduction of hypophosphorous acid. The oxidatio...

Herein, a technological process for the fabrication of n-type doped V-shaped structures on (100) single-crystalline diamond substrates, designed to overcome limitations doping surfaces, is presented. This enhancement can be applied realize electronic power devices such as junction barrier Schottky diode or field effect transistors with low on-resistance. catalytic etching performed by using squ...

Acrylic acid is an important commodity chemical and is widely used as a base material for the industrial production of paints, plastics, superabsorbent polymers, rubber, and so on. Currently acrylic acid is produced by partial oxidation of propene, which is refined from petroleum. Catalytic hydrocarboxylation of acetylene with CO is another way to synthesize acrylic acid with high atom-economy....

introduction: sequential batch reactor (sbr) is one of the modified biological treatment systems which is able to remove bod5, nitrogen, and phosphorus from wastewater. the object of this study is to determine the removal efficiency of nitrogen, phosphorus, and heavy metals from municipal wastewater by the advanced sbr system. methods: this descriptive-analytical and cross-sectional study was c...
