2,6-diaminopyridine is extensively used as a pharmaceutical intermediate and a hair dye coupler as oxidation formulations. it is soluble in protic solvents. primary and secondary amines are n-methylated by various methods such as direct alkylation of amines with hofmann mechanism, but in many of these methods due to overalkylations, we earn a mixture of amino products. consequently, they aren't...

Hotly debated these days is whether nickel or iron the active site in nickel–iron water oxidation electrocatalysts. We have previously argued that a likely candidate for highly materials because it can reach high-oxidation (high-ox) states at potentials relevant to splitting. Here, we further assert not an electrocatalysis materials. Our 3-fold argument supported by electrochemical measurements...

In this paper, the photochemical degradation of azure-b by Cu2+/S2O82− process has beenpresented. Cu2+ as photocatalyst and S2O82− ion as photooxidant used in this process. Atextremely low concentrations, cupric ion showed true catalytic activity in the overall process.The influence of various parameters on the performance of the treatment process has beenconsidered, such as pH, concentration o...

Using a first-principles pseudopotential technique within a generalized gradient approximation of the density functional theory, we have investigated the mechanism of adsorption of molecular oxygen on the CdTe(110) surface. The determination of the more favorables structures and their formation through the activation barrier analysis indicates that the formation can occur in the regimes of low ...
