Stability constants of complexes
In coordination chemistry, a stability constant (also called formation constant or binding constant) is an equilibrium constant for the formation of a complex in solution. It is a measure of the strength of the interaction between the reagents that come together to form the complex.There are two main kinds of complex: compounds formed by the interaction …
Polyaniline-intercalated manganese dioxide nanolayers as …
Rechargeable zinc–manganese dioxide batteries that use mild aqueous electrolytes are attracting extensive attention due to high energy density and environmental friendliness. Unfortunately ...
Rechargeable aqueous zinc-manganese dioxide batteries …
The development of rechargeable aqueous zinc batteries are challenging but promising for energy storage applications. With a mild-acidic triflate electrolyte, here the authors show a high ...
Carbon dioxide
Carbon dioxide (chemical formula CO 2) is a chemical compound made up of molecules that each have one carbon atom covalently double bonded to two oxygen atoms. It is found in the gas state at room temperature. In the air, carbon dioxide is transparent to visible light but absorbs infrared radiation, acting as a greenhouse gas.It is a trace gas in …
Lithium-ion battery
A Lithium-ion or Li-ion battery is a type of rechargeable battery which uses the reversible reduction of lithium ions to store energy. It is the predominant battery type used in portable consumer electronics and electric vehicles.It also sees significant use for grid-scale energy storage and military and aerospace applications. Compared to other …
Competitive extraction and stripping behaviors of rare …
Furthermore, Pavon et al., developed an extraction process for purifying phosphoric acid through removing trivalent metal impurities and recovering REEs via a cross-flow solvent extraction process. Fe 3+ was removed in two stages using Cyanex 572 with extraction ratio of 98.1 %, and 96.6 % of REEs were subsequently recovered by Cyanex 923 in ...
