The Calvin cycle, also known as the dark reactions, is a series of biochemical reactions that fixes CO2 into G3P sugar molecules and uses the energy and electrons from the ATP and NADPH made in the light reactions.
The Calvin cycle takes place in the stroma of the chloroplast.
While named ""the dark reactions"", in most plants, they take place in the light, since the dark reactions are dependent on the products of the light reactions. 
Dynamical properties of reaction networks were studied in chemistry and physics after invention of the law of mass action.
The essential steps in this study were introduction of detailed balance for the complex chemical reactions by Rudolf Wegscheider (1901), development of the quantitative theory of chemical chain reactions by Nikolay Semyonov (1934), development of kinetics of catalytic reactions by Cyril Norman Hinshelwood, and many other results.
The mathematical discipline "chemical reaction network theory" was originated by Rutherford Aris, a famous expert in chemical engineering, with support of Clifford Truesdell, the founder and editor-in-chief of the journal "Archive for Rational Mechanics and Analysis".
The paper of R. Aris in this journal was communicated to the journal by C. Truesdell.
It opened the series of papers of other authors (which were communicated already by R Aris).
The well known papers of this series are the works of Frederick J. Krambeck, Roy Jackson, Friedrich Josef Maria Horn, Martin Feinberg and others, published in the 1970s.
In his second "prolegomena" paper, R. Aris mentioned the work of N.Z.
Shapiro, L.S.
Shapley (1965), where an important part of his scientific program was realized.
Since then, the chemical reaction network theory has been further developed by a large number of researchers internationally. 
The names for chemical elements in East Asian languages, along with those for some chemical compounds (mostly organic), are among the newest words to enter the local vocabularies.
Except for those metals well-known since antiquity, most elements had their names created after modern chemistry was introduced to East Asia in the 18th and 19th century, with more translations being coined for those elements discovered later.
While most East Asian languages use—or had used—the Chinese script, only the Chinese use the characters as the predominant way of naming elements.
On the other hand, the Japanese, Koreans and Vietnamese primarily employ native alphabets for the names of the elements (Katakana, Hangul and Quốc Ngữ, respectively). 
Calorimetry is the measurement of the heat released or absorbed by chemical reactions.
These assays are very general, since many reactions involve some change in heat and with use of a microcalorimeter, not much enzyme or substrate is required.
These assays can be used to measure reactions that are impossible to assay in any other way. 
While the dimensions of the individual channels are small, a microprocess engineering device ("microstructured reactor") can contain manythousands of such channels, and the overall size of a microstructuredreactor can be on the scale of meters.
The objective of micro processengineering is not primarily to miniaturize production plants,but to increase yields and selectivities of chemical reactions, thusreducing the cost of chemical production.
This goal can be achieved byeither using chemical reactions that cannot be conducted in largervolumina, or by running chemical reactions at parameters (temperatures,pressures, concentrations) that are inaccessible in larger volumina dueto safety constraints.
For example, the detonation of thestoichiometric mixture of two volume unit of hydrogen gas andone volume unit of oxygen gas does not propagate in microchannelswith a sufficiently small diameter.
This property is referred to as the"intrinsic safety" of microstructured reactors.
The improvement of yieldsand selectivities by using novel reactions or running reactions at moreextreme parameters is known as "process intensification".
