41Surface forces apparatus — The surface force apparatus (SFA) is a scientific instrument and technique pioneered by D. Tabor, R.H.S. Winterton, J.N. Israelachvili in the early 1970s at Cambridge University. By the mid 70 s Israelachvili had adapted the original design to… …
42Surface metrology — is the measuring of small scale features on surfaces, and is a branch of Metrology. Surface primary form, surface waviness and surface roughness are the parameters most commonly associated with the field. It is important to many disciplines and… …
43Surface states — are electronic states found at the surface of materials and are part of condensed matter physics. They are formed due to the sharp transition from solid material that ends with a surface and are found only at the atom layers closest to the… …
44Surface supplied diving — (also known as Hooka diving) refers to divers using equipment supplied with breathing gas using an umbilical cord from the surface, often from a diving support vessel but possibly, indirectly via a diving chamber.cite journal |author=Gernhardt,… …
45Surface brightness — is a concept used in astronomy when describing extended astronomical objects such as galaxies and nebulae.General descriptionThe apparent magnitude of an astronomical object is generally given as an integrated value mdash;if a galaxy is quoted as …
46Surface wave magnitude — The Surface wave magnitude (MS) is one of the magnitude scales used in seismology to measure the size of an earthquake. It is based on measurements in Rayleigh surface waves that primarily travel along the uppermost layers of the earth. It is… …
47Surface finishing — is a broad range of industrial processes that alter the surface of a manufactured item to achieve a certain property.[1] Finishing processes may be employed to: improve appearance, adhesion or wettability, solderability, corrosion resistance,… …
48Surface conductivity — is an additional electric conductivity of fluid in the vicinity of the charged surface. Fluid conductivity is associated with ions motion in electric field. Concentration of ions is higher close to the charged surfaces. They are attracted there… …
49Surface Water Ocean Topography Mission — The Surface Water Ocean Topography (SWOT) Mission is a proposed NASA mission to make the first global survey of Earth’s surface water. It is one of 15 missions that the 2007 National Research Council’s decadal survey of Earth science recommends… …
50Surface layer — The surface layer is the layer of a turbulent fluid most affected by interaction with a solid surface or the surface separating a gas and a liquid. In surface layers the characteristics of the turbulence depend on distance from the interface.… …
