Surface Analysis
A surface is the outermost layer of any physical object. It is the portion of the object that can be perceived by an observer using their sense of sight and touch and is the portion with which surrounding materials first interact. The outermost part of a material is an extremely important component responsible for interfacial characteristics such as chemical reactivity, adhesion, wetness, electrical properties, optical properties, corrosion-resistance, friction, and biocompatibility of the material.
