Huang Feihe at Zhejiang University, Jonathan Sessler of the University of Texas at Austin, and colleagues reported a novel cation recognition mode which mimics the biological allosteric effect and ...

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.

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 ...

Cations are ions that are positively charged. Anions are ions that are negatively charged. Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it will become a ...

A chemistry professor has uncovered a major development in the study of anions, negatively-charged molecules such as chloride, bromide and nitrate, which have strategic roles within the human body.

Cations are ions that are positively charged. Anions are ions that are negatively charged. Ions are charged atoms or molecules. If a balanced atom loses one or more electrons, it will become a ...
