51gas chromatography — n. chromatography in which a gas, often nitrogen, combines with a vaporized mixture that is then passed through a long column of adsorbent material to identify its constituents * * * ▪ chemistry in analytical chemistry, technique for… …
52Auxiliary field Monte Carlo — is a method that allows the calculation, by use of Monte Carlo techniques, of averages of operators in many body quantum mechanical (Blankenbecler 1981, Ceperley 1977) or classical problems (Baeurle 2004, Baeurle 2003, Baeurle 2002a).The… …
53Cellulose — is an organic compound with the formula chem|(C|6|H|10|O|5|)|n, a polysaccharide consisting of a linear chain of several hundred to over ten thousand β(1→4) linked D glucose units.cite book author=Crawford, R. L. title=Lignin biodegradation and… …
54Gel permeation chromatography — (GPC) is a separation technique based on hydrodynamic volume (size in solution). Molecules are separated from one another based on differences in molecular size. This technique is often used for polymer molecular weight determination. GPC is… …
55Dye-sensitized solar cell — A selection of dye sensitized solar cells A dye sensitized solar cell (DSSC, DSC or DYSC[1]) is a low cost solar cell belonging to the group of thin film solar cells.[2] …
56Time-frequency representation — A time frequency representation (TFR) is a view of a signal (taken to be a function of time) represented over both time and frequency. Time frequency analysis means analysis of a TFR. TFRs are often complex valued fields over time and frequency,… …
57Fractionation — See also: Fractionated spacecraft Fractionation is a separation process in which a certain quantity of a mixture (solid, liquid, solute, suspension or isotope) is divided up in a number of smaller quantities (fractions) in which the composition… …
58Riemann-Lebesgue lemma — In mathematics, the Riemann Lebesgue lemma (one of its special cases is also called Mercer s theorem), is of importance in harmonic analysis and asymptotic analysis. It is named after Bernhard Riemann and Henri Lebesgue. The lemma says that the… …
59Molar mass distribution — In linear polymers the individual polymer chains rarely have exactly the same degree of polymerization and molar mass, and there is always a distribution around an average value. The molar mass distribution (or molecular weight distribution) in a …
