1D-chiro-Inositol [2] or D-chiro-inositol [3] (often abbreviated DCI) is a chemical substance with formula C6H12O6, one of the nine isomers of cyclohexane-1,2,3,4,5,6-hexol (which may be collectively called "inositol"). The molecule has a ring of six carbon atoms, each bound to one hydrogen atom and one hydroxyl (OH) group.
Glossary of mathematical symbols. A mathematical symbol is a figure or a combination of figures that is used to represent a mathematical object, an action on mathematical objects, a relation between mathematical objects, or for structuring the other symbols that occur in a formula. As formulas are entirely constituted with symbols of various ...
This was defined by Todeschini and Consonni as: " The molecular descriptor is the final result of a logic and mathematical procedure which transforms chemical information encoded within a symbolic representation of a molecule into a useful number or the result of some standardized experiment. " [1]
Computational chemistry is a tool for analyzing catalytic systems without doing experiments. Modern electronic structure theory and density functional theory has allowed researchers to discover and understand catalysts. [37] Computational studies apply theoretical chemistry to catalysis research.
Mole ratio. In atmospheric chemistry, mixing ratio usually refers to the mole ratio ri, which is defined as the amount of a constituent ni divided by the total amount of all other constituents in a mixture: The mole ratio is also called amount ratio. [2] If ni is much smaller than ntot (which is the case for atmospheric trace constituents), the ...
This glossary of chemistry terms is a list of terms and definitions relevant to chemistry, including chemical laws, diagrams and formulae, laboratory tools, glassware, and equipment. Chemistry is a physical science concerned with the composition, structure, and properties of matter , as well as the changes it undergoes during chemical reactions ...
e. In information theory, the noisy-channel coding theorem (sometimes Shannon's theorem or Shannon's limit ), establishes that for any given degree of noise contamination of a communication channel, it is possible (in theory) to communicate discrete data (digital information) nearly error-free up to a computable maximum rate through the channel.
