Valency is the combining power of an element. Elements in the same group of the periodic table have the same valency. The valency of an element is related to how many electrons are in the outer shell.

Spectral tunability, to allow control over the direction of energy flow among constituent quantum dots in a single complex. Ideally, the tunability is realized based on systematically varying a single ...

Researchers analyzed the effects of solvation and ion valency on metallopolymers, with implications for critical materials recovery and recycling, and environmental remediation. In a new paper ...

Designing a vaccine starts with finding the right ingredients. Every infectious agent has molecules, called antigens, that the immune system could potentially recognize and attack. So scientists must ...
