In order to reveal to what extent tritium (H or T) can be incorporated into hydroxides, the isotope exchange reaction (OT-for-OH exchange reaction) between alkali metal hydroxides (MOH), where M means alkali metal, and HTO water was observed homogeneously at 70 C under equilibrium after ...

reaches the Rayleigh instability limit, which leads to a ‘coulomb explosion’ of the alkali metal drop. Consequently, a new metal surface in contact with water is formed, which explains why the reaction does not become self-quenched by its products, but can rather lead to explosive behaviour....

electrostatic spray-assisted vapor deposited Cu2ZnSn(S,Se)4 solar cells Giovanni Altamura, Mingqing Wang & Kwang-Leong Choy Electrostatic Spray-Assisted Vapor Deposition (ESAVD) is a non-vacuum and cost-effective method to deposit metal oxide, various sulphide and chalcogenide at large ...
Carboxylations of alkali metal phenoxides with carbon dioxide. The reaction mechanism of the Kolbe–Schmitt reaction of phenol and 2-naphthol has been investigated. An alkali metal phenoxide–CO2complex is not an inter... Y Kosugi,Y Imaoka,F Gotoh,... - 《Organic & Biomolecular Chemistry》...
Small particles of cellulose-containing plants, fine granular oxidated, silicon compounds and an alkali metal hydroxide are mixed, then heated to 150° C. to 220° C. while agitating until the plant particles soften or melt, thereby producing an alkali metal cellulose silicate condensation product...
The tests also indicated that the removal of alkali metal vapor with activated Al2O3is a physical adsorption process in the absence of water that supports the chemical reaction involved. From these studies, it is inferred that a) adsorption of alkali compounds on activated alumina will occur ...

The platinum-catalysed hydrogen evolution reaction (HER) generally shows poorer kinetics in alkaline electrolyte and represents a key challenge for alkaline water electrolysis. In the presence of alkali metal cations and hydroxyl anions, the electrode–electrolyte (platinum–water) interface in an alkaline...
