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 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 ...

Dual-ion batteries (DIBs), in which both cations and anions are involved in the electrochemical redox reaction, are one of the most promising candidates to meet the low-cost requirements of commercial ...

The spontaneity of redox reactions is demonstrated using copper, zinc, and silver, and their cations. When solid zinc is placed in Cu2+ solution, the blue color of the solution becomes less intense as ...

A team of engineers has transformed simple nanowires into reconfigurable materials and circuits, demonstrating a novel, self-assembling method for chemically creating nanoscale structures that are not ...

Figure 1: Schematic of electrochemical reactions and experimental configuration. Figure 2: Core-level binding energy shifts as a function of ohmic-corrected bias. Figure 3: Operando oxygen K-edge and ...

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 ...

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 ...

(Nanowerk News) A team of engineers from the University of Pennsylvania has transformed simple nanowires into reconfigurable materials and circuits, demonstrating a novel, self-assembling method for ...
