Laser Ablation Laser ablation is the process of removing material from a solid (or occasionally liquid) surface by irradiating it with a laser beam. At low laser flux, the material is heated by the absorbed laser energy and evaporates or sublimates. At high laser...

Phase Rule For a system at equilibrium the phase rule relates: P = number of phases that can coexist, to C = number of components making up the phases, and F = degrees of freedom. Where these three variables are related in the equation P + F = C + 2 The degrees of...
