Interfaces are the quasi two-dimensional regions of separation between pieces of matter: they may be free surfaces, or the internal surfaces of separation between liquid or micro-crystalline blocks of matter. The maze of such interfaces is the essence of polycrystalline substances such as metals, ceramics and intermetallics. In this paper a wide variety of interfacial phenomena are presented, including solid surfaces, grain boundaries and fluid interfaces. It is demonstrated that the same fundamental laws of capillarity apply to processes and properties which are of practical interest. A basic understanding of interfaces is the key that will open up opportunities to engineer materials for the growing demands of new technologies.
