A cation refers to an atom or a group of atoms that bear one or multiple positive electric charges. An anion refers to an atom or a group of atoms that bear one or multiple negative electric charges.

Anion exchange membrane fuel cells (AEMFCs) have gained attention in the process of fuel cell development because they operate in alkaline environments, the redox reaction rate at the electrodes is ...

The New Philadelphia Science Club is back with another science question in The Times-Reporter. Each week a new science-related question will be given, and everyone is invited to participate by either ...

Chemists have found that the all-cis isomer of hexafluorocyclohexane, a molecule that made headlines last year for being the most polar aliphatic compound known, is capable of binding both cations and ...

Charged particles in aqueous solutions are always surrounded by a shell of water molecules. However, much is still unknown about the nature of this so-called hydration shell. Using terahertz ...

A unique phenomenon of mitochondria-targeted protonophores is described. lt consists in a transmembrane H⁺-conducting fatty acid cycling mediated by penetrating cations such as 10-(6'-plastoquinonyl) ...

Cations can be identified with flame tests or precipitate tests using sodium hydroxide and ammonia solutions. Anions (halide, sulfate, and carbonate ions) can be identified using precipitate tests or ...

Chromatography is the science of separating molecules of interest to identify, quantify or even purify them. Properties of the target molecules such as their solubility, size or hydrophobicity give ...
