2surface analysis — ▪ chemistry Introduction in analytical chemistry (chemistry), the study of that part of a solid that is in contact with a gas or a vacuum. When two phases of matter are in contact, they form an interface. The term surface is usually… …
3Surface 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… …
4Surface 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… …
5Surface 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… …
6Surface enhanced Raman spectroscopy — Surface Enhanced Raman Spectroscopy, or Surface Enhanced Raman Scattering, often abbreviated SERS, is a surface sensitive technique that results in the enhancement of Raman scattering by molecules adsorbed on rough metal surfaces. The enhancement …
7Surface second harmonic generation — is a method for probing interfaces in atomic and molecular systems. In second harmonic generation (SHG), the light frequency is doubled, essentially converting two photons of the original beam of energy E into a single photon of energy 2 E as it… …
8Surface weather observation — Surface weather observations are the fundamental data used for safety as well as climatological reasons to forecast weather and issue warnings worldwide. [Office of the Federal Coordinator of Meteorology. [http://www.ofcm.gov/fmh 1/pdf/B CH2.pdf… …
9Surface diffusion — [ adatom diffusing across a square surface lattice. Note the frequency of vibration of the adatom is greater than the jump rate to nearby sites. Also, the model displays examples of both nearest neighbor jumps (straight) and next nearest neighbor …
10Surface phenomenon — A Surface phenomenon is a phenomenon that take place on or near the surface of a substance or phase. In most cases, the special properties of a surface cause these unique phenomena. There are two important surface related phenomena:… …
