Zinc alloy powders for alkaline batteries
<p>"Zinc (Zn) powders form the anode of a modern alkaline battery. During discharge of the battery, zinc oxidizes to produce zinc oxide and electrons. Alkaline batteries are prone to leakage during storage. This phenomenon is caused by zinc dissolving into the alkaline solution and producing …

Moderately-rapid assessment of alkaline desiccation environmental systems
… and technical data. The treatment process was an alkaline-desiccation process with mean pH values of 8.2 ± sd 1.1 and water content of 18.3% ± sd 9.9, which resulted in mean fecal coliform values of 15.0 MPN/g ± sd 31.8, drastically lower than the 1000 MPN/g United States Environmental Protection …

Amorphous Ni-based Alloys as Alkaline Oxygen Evolution Electrocatalysts
The overall efficiency of many electrochemical conversion and storage technologies, such as water electrolysis and CO2 conversion, is hindered by sluggish oxygen evolution reaction (OER) kinetics. Amorphous alloys display enhanced OER kinetics and stability over their crystalline counterparts but …

Mineral sequestration of CO2 by reaction with alkaline residues
… mineral sequestration of CO2 was studied, using alkaline residue materials. This study examined for the first time a process that allows for rapid removal of CO2 from flue gas through reaction with lignite fly ashes in aqueous solution. In this process the basicity of the residues is utilized for …
