Low E glass — Low emission glass reflects up to 90% of long wave radiation, which is heat, but lets in short wave radiation, which is light. Windows are glazed with a coating that bonds a microscopic, transparent, metallic substance to the inside surface of… … Energy terms
Surface reconstruction — refers to the process by which atoms at the surface of a crystal assume a different structure than that of the bulk. Surface reconstructions are important in that they help in the understanding of surface chemistry for various materials,… … Wikipedia
Surface science — is the study of physical and chemical phenomena that occur at the interface of two phases, including solid liquid interfaces, solid gas interfaces, solid vacuum interfaces, and liquid gas interfaces. It includes the fields of surface chemistry… … Wikipedia
