Surface
71Surface charge — is the electric charge present at an interface, for instance on the surface of a semiconductor material, or for example, on the surface of a protein in water.There are multiple factors generating surface charge. First of all, surface charge… …
72Surface plasmon — Surface plasmons, also referred to in the literature as surface plasma polaritons, are fluctuations in the electron density at the boundary of two materials. Plasmons are the collective vibrations of an electron gas (or plasma) surrounding the… …
73Surface de riemann — Pour les articles homonymes, voir Surface (homoymie). En géométrie différentielle, une surface de Riemann est une variété différentielle analytique complexe de dimension 1. Par oubli de structure, une surface de Riemann se présente comme une… …
74Surface grinding — is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or non metallic substance from a workpiece, making a… …
75Surface area — is the measure of how much exposed area an object has. It is expressed in square units. If an object has flat faces, its surface area can be calculated by adding together the areas of its faces. Even objects with smooth surfaces, such as spheres …
76Surface-mount technology — (SMT) is a method for constructing electronic circuits in which the components (SMC, or Surface Mounted Components) are mounted directly onto the surface of printed circuit boards (PCBs). Electronic devices so made are called surface mount… …
77Surface engineering — is the sub discipline of materials science which deals with the surface of solid matter. It has applications to chemistry, mechanical engineering, and electrical engineering (particularly in relation to semiconductor manufacturing).Solids are… …
78Surface de derniere diffusion — Surface de dernière diffusion Pour les articles homonymes, voir Surface (homoymie). La surface de dernière diffusion est la région de l espace d où a été émis le rayonnement électromagnétique le plus ancien de l univers que l on observe aujourd… …
79Surface condensation — Surface Sur face , n. [F. See {Sur }, and {Face}, and cf. {Superficial}.] 1. The exterior part of anything that has length and breadth; one of the limits that bound a solid, esp. the upper face; superficies; the outside; as, the surface of the… …
