The ionizable groups incorporated into the polymer are formed by the reaction of an acid and a base to form a salt. The particular charge, positive or negative, which is imparted to the polymer depends on the chemical nature of the ionizable group. If the ionizable groups on the polymer are acids, the polymer will carry a negative charge when ...
Arc discharges at atmospheric pressure are self-sustained DC electric discharges with large electric currents, typically higher than 1 A, in some cases reaching up to 100.000 A, and relatively low voltages, typically of the order of 10 – 100 V. Due to high collision frequencies of plasma species, atmospheric pressure arcs are in thermal equilibrium having temperatures of the order of 6.000 ...
Ethyl acetate, a nail polish solvent. [1]A solvent (from the Latin solvÅ, "loosen, untie, solve") is a substance that dissolves a solute, resulting in a solution.A solvent is usually a liquid but can also be a solid, a gas, or a supercritical fluid.
When a chemical reaction is driven by an electrical potential difference, as in electrolysis, or if a potential difference results from a chemical reaction as in an electric battery or fuel cell, it is called an electrochemical reaction. Unlike in other chemical reactions, in electrochemical reactions electrons are not transferred directly ...

The chemical will still be available for certain purposes, but with new guidelines meant to keep workers safe. EPA implements toughest restrictions yet on use of highly toxic chemical in paint ...
Redox couple for a viologen.The 2+ species on the left is colorless, and the 1+ species on the right is deep blue or red, depending on the identity of R. [1] Electrochromism is a phenomenon in which a material displays changes in color or opacity in response to an electrical stimulus. [2]
The Environmental Protection Agency said Tuesday it has finalized a ban on consumer uses of methylene chloride, a chemical that is widely used as a paint stripper but is known to cause liver ...
