These positively charged molecules help attract and guide negatively charged ions—called anions—through the membrane while repelling positively charged ions—called cations. The membranes are ...

There are three isotopes of hydrogen: hydrogen, deuterium (hydrogen-2) and tritium (hydrogen-3): if the atom loses one or more electrons, it becomes a positively-charged ion if the atom gains one ...

The scientists determined the three-dimensional structure of the protein and found that there are positively charged calcium ...

“At low temperatures, models of reactivity must include the effects of the permanent electric dipoles and quadrupole moments ...

The acid reacts with any carbonate ions present. This removes them, so stopping them giving a false positive result. Sulfuric acid, H 2 SO 4 (aq), contains sulfate ions. These would react with ...

Focused on the flow of ions AEMs are thin, specially designed materials embedded with positively charged molecules. These positively charged molecules helps attract and guide negatively charged ...
