In chemistry,cationsare indicated with a plus sign (+) andanionsare indicated with a minus sign (-), with the number of symbols indicating the number of electrons lost or gained (this is called an atom’svalence). For example, the symbolsNa+andCa++indicatecations, whileCl-indicates ananion...
Contaminant Analysis: Cation vs Anion Cations and anions are both types of ions that are electrically charged. While they each have important natural roles to play in chemistry, they can also be a serious problem if they find their way into systems where they are not supposed to belong. This...
The neutral silicon chemistry in the flame is dominated by SiO, but evidence was obtained from both the cation and the anion chemistry for the presence of HSiO(OH), silanoic acid; SiO(OH)2, metasilicic acid; and Si(OH)4, orthosilicic acid. The silicon ion chemistry differs markedly ...

This work presents a versatile chemistry platform for the fabrication of hierarchical cation and anion exchange membranes (hCEMs and hAEMs) with tuneable transport properties. A strong focus was put onto developing cost-effective membranes fabricated through a sustainable and easily scalable process, wit...

(pDOS). We did not include Co in our calculations due to its low concentration in our experimentally studied material. Ceder and coworkers have recently shown that anion redox chemistry is most strongly affected by the anion nearest-neighbor coordination environment23. We therefore designed the ...

(Fig.6b). Three-coordinate borenium dications are extremely rare66,67, and no further redox chemistry has been reported for the isolated systems, possibly due to the presence of strongly π-donating ligands tailor-made to stabilize these highly electron-deficient species68,69,70. Hence,12+...
