72BCS theory — is a microscopic theory of superconductivity, proposed by Bardeen, Cooper, and Schrieffer. It describes superconductivity as a microscopic effect caused by Bose condensation of pairs of electrons.HistoryBCS theory was developed in 1957 by John… …
73HSAB theory — The HSAB concept is an acronym for hard and soft (Lewis) acids and bases. Also known as the Pearson acid base concept, HSAB is widely used in chemistry for explaining stability of compounds, reaction mechanisms and pathways. It assigns the terms… …
74Entropy in thermodynamics and information theory — There are close parallels between the mathematical expressions for the thermodynamic entropy, usually denoted by S , of a physical system in the statistical thermodynamics established by Ludwig Boltzmann and J. Willard Gibbs in the 1870s; and the …
75Bragg-Gray Cavity Theory — According to the Bragg Gray cavity theory, the ionization produced within a gas filled cavity inside a medium is related to the energy absorbed in that surrounding medium. If the cavity is small enough that it does not change the number or… …
76Receptor theory — is the application of receptor models to explain drug behaviour. [cite journal |author=Kenakin T |title=What systems can and can t do |journal=Br. J. Pharmacol. |volume=153 |issue=5 |pages=841–3 |year=2008 |pmid=18204481… …
77Drip gas — is a naturally occurring form of gasoline found near many oil and natural gas wells, in natural gas pipelines, and as a byproduct of natural gas extraction. It is also known as natural gasoline, casing head gas, raw gas, white gas, and liquid… …
78Polymer field theory — A polymer field theory within the framework of statistical mechanics is a statistical field theory, describing the statistical behavior of a neutral or charged polymer system within the field theoretic approach.It can be derived by transforming… …
79perfect gas — Physics. See ideal gas. [1840 50] * * * or ideal gas Gas whose physical behaviour conforms to the general gas law, which states that for a given quantity of gas, the product of the volume V and pressure P is proportional to the absolute… …
80Electrochemical gas sensor — Electrochemical gas sensors are gas detectors that measure the volume of a target gas by oxidizing or reducing the target gas at an electrode and measuring the resulting current. ConstructionThe sensors contain two or three electrodes,… …
