The Compendium of Analytical Nomenclature is an IUPAC nomenclature book published by the International Union of Pure and Applied Chemistry (IUPAC) containing internationally accepted definitions for terms in analytical chemistry. [1] It has traditionally been published in an orange cover, hence its informal name, the Orange Book.
A fundamental difference exists between chemistry as it is performed in most laboratories and chemistry as it occurs in life. Laboratory processes are mostly designed such that the (closed) system goes thermodynamically downhill; i.e. the product state is of lower Gibbs free energy, yielding stable molecules that can be isolated and stored.
Also acid ionization constant or acidity constant. A quantitative measure of the strength of an acid in solution expressed as an equilibrium constant for a chemical dissociation reaction in the context of acid-base reactions. It is often given as its base-10 cologarithm, p K a. acid–base extraction A chemical reaction in which chemical species are separated from other acids and bases. acid ...
Chemistry stencils that used to be used for drawing equipment in lab notebooks. A laboratory notebook (colloq. lab notebook or lab book) is a primary record of research. Researchers use a lab notebook to document their hypotheses, experiments and initial analysis or interpretation of these experiments.

For example, the E. coli 70S was represented as 4 PDB files in 2009: 3I1M Archived 2016-10-05 at the Wayback Machine, 3I1N Archived 2016-10-16 at the Wayback Machine, 3I1O, and 3I1P. In 2014, they were consolidated into a single file, 4V6C. In 2014, the PDB format was officially replaced with mmCIF, and newer PDB structures may not have PDB ...
Structural chemistry can contribute to the design of eco-friendly materials and catalysts, promoting sustainable practices in the chemical industry. Recent development of metal-free nanostructured catalysts is one of the advancements in the field of structural chemistry that has the potential to drive organic transformations in a sustainable ...
Organic chemistry is a subdiscipline within chemistry involving the scientific study of the structure, properties, and reactions of organic compounds and organic materials, i.e., matter in its various forms that contain carbon atoms. [1]
