Density refers to the mass of a material per unit volume. Cured density is determined in an adhesive after the curing (hardening) process. Density measurements are useful for evaluating the uniformity ...

The normal modes and the density of states (DOS) of any material provide a basis for understanding its thermal and mechanical transport properties. In perfect crystals, normal modes are plane waves, ...
