Roads to pentazolate anion: a theoretical insight [PDF]
Royal Society Open Science, 2018 The formation mechanism of pentazolate anion (PZA) is not yet clear. In order to present the possible formation pathways of PZA, the potential energy surfaces of phenylpentazole (PPZ), phenylpentazole radical (PPZ-R), phenylpentazole radical anion (PPZ ...

Mechanistic evidence for a front-side, SNi-type reaction in a retaining glycosyltransferase [PDF]
, 2011 A previously determined crystal structure of the ternary complex of trehalose-6-phosphate synthase identified a putative transition state–like arrangement based on validoxylamine A 6?-O-phosphate and uridine diphosphate in the active site.

Reaction mechanism of sulfate attack on alkali-activated slag/fly ash cements
, 2022 In this work, the effects of slag/fly ash ratios, Na2O concentration, and silicate modulus (Ms) of activators on the reaction mechanism of sulfate attack on alkali-activated slag/fly ash cements are elucidated by XRD, FTIR, and TG/DTG analysis.

The Mechanism of the Agglutination Reaction [PDF]
Epidemiology and Infection, 1917 Since Gruber and Nicolle expressed the opinion that the agglutination of bacteria by specific immune sera was due to the surfaces of the bacteria becoming viscous under the influence of the specific sera, many theories have been advanced aiming at a more complete explanation of the reaction. Bordet (1899) considered that the agglutinins by uniting with

Hydration mechanism of heterogeneous alkaline deacetylation of chitin [PDF]
Vestnik MGTU, 2017 In the work the hypothesis has been proposed explaining the features of the kinetics of chitin/chitosan alkali deacetylation reaction in highly concentrated solutions of sodium hydroxide, which almost completely stops after 30–60 min after the start of ...

A DFT investigation of the blue bottle experiment: E∘half-cell analysis of autoxidation catalysed by redox indicators [PDF]
Royal Society Open Science, 2017 The blue bottle experiment is a collective term for autoxidation reactions catalysed by redox indicators. The reactions are characterized by their repeatable cycle of colour changes when shaken/left to stand and intricate chemical pattern formation.
