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 ...
Methylisothiazolinone (/ ˌ m ɛ θ əl ˌ aɪ s oʊ ˌ θ aɪ. ə ˈ z oʊ l ɪ n oʊ n /), MIT, or MI, is the organic compound with the formula S(CH) 2 C(O)NCH 3. It is a white solid. Isothiazolinones, a class of heterocycles, are used as biocides in numerous personal care products and other industrial applications.
According to AI Index at Stanford, the annual number of AI-related laws passed in the 127 survey countries jumped from one passed in 2016 to 37 passed in 2022 alone. [ 324 ] [ 325 ] Between 2016 and 2020, more than 30 countries adopted dedicated strategies for AI. [ 326 ]
The artificial intelligence (AI) boom has brought with it a cornucopia of jargon — from "generative AI" to "synthetic data" — that can be hard to parse. An AI glossary: The words and terms to ...
Pronounced "A-star". A graph traversal and pathfinding algorithm which is used in many fields of computer science due to its completeness, optimality, and optimal efficiency. abductive logic programming (ALP) A high-level knowledge-representation framework that can be used to solve problems declaratively based on abductive reasoning. It extends normal logic programming by allowing some ...
In the Simmons–Smith reaction, it is a source of methylene. [4] In fact the Simmons–Smith reaction does not produce free carbene but proceeds via Zn-CH 2 I intermediates. Diiodomethane is also a source of the equivalent of CH 2+ 2. The synthesis of Fe 2 (CH 2)(CO) 8 illustrates this reactivity: [5] Na 2 Fe 2 (CO) 8 + CH 2 I 2 → Fe 2 (CH 2 ...
Second, medical roots generally go together according to language, i.e., Greek prefixes occur with Greek suffixes and Latin prefixes with Latin suffixes. Although international scientific vocabulary is not stringent about segregating combining forms of different languages, it is advisable when coining new words not to mix different lingual roots.
Combinatorial chemistry comprises chemical synthetic methods that make it possible to prepare a large number (tens to thousands or even millions) of compounds in a single process. These compound libraries can be made as mixtures, sets of individual compounds or chemical structures generated by computer software. [ 1 ]
