0 the simplest unit of a chemical substance, usually a group of two or more atoms
1 the smallest unit into which a substance can be divided without chemical change, usually a group of two or more atoms
It permits simulation of the coupled dynamics of valence electrons and ionic cores in a molecule or a material.
In addition, the dielectric constant in the pore region should be set to 1 where the water molecules are represented explicitly (but see discussion below).
The surface density of streptavidin molecules was sufficiently small that each of the pinning sites represented a single streptavidin-biotin cross-bridge.
Table 1) that determines how close two molecules or surfaces can get.
A force that exists only between charged molecules (ions) or surfaces.
Newer strategies have emerged that interfere with the activities of endothelial-cell molecules without targeting immune cells and eliciting the adverse effects associated with steroid usage.
All of these adhesion molecules have been proposed as vaccine targets.
The energy taken up by the sorbent is transferred to the adsorbed substances, both water and acid molecules.
