Caractérisation des sous-produits d'oxydation des boues en conditions sous-critiques et supercritiques [PDF]
, 1995 L'élimination de la matière organique et la réduction de volume des boues peuvent être obtenues par incinération, par oxydation sous pression en milieu humide ("wet air oxidation") ou par combustion en eau supercritique ("supercritical water oxidation").

Étude théorique d'un mécanisme de co-oxydation Theorical Analysis of Cooxidation Mechanism
Oil & Gas Science and Technology, 2006 L'étude théorique de la co-oxydation de deux substances oxydables RH et R'H est effectuée systématiquement à partir d'un schéma cinétique général et en envisageant successivement les différents cas possibles. Dans cette étude, on admet que RH s'oxyde, en

Oxydation de solutions d’acide iodhydrique par l’air en présence de lumière
CHIMIA, 1972 The reaction 4 HI + O2 →hν 2 H2O + I2 has been studied as a possibility of regeneration of the cathodic fuel in a cell using the cathodic reaction I2 + 2 e- → 2 I-.

Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis
Asian Journal of Organic Chemistry, Volume 14, Issue 8, August 2025.This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.

International Journal of Cosmetic Science, Volume 47, Issue 4, Page 604-625, August 2025.The protein carbonylation biomarker is validated as reliable molecular damage marker to monitor hair oxidative damage (chemical and photo oxidation). It is slightly more sensitive than the cysteic acid in the case of photochemical oxidation and allows to geolocate qualitatively and quantitatively the oxidation within the hair fibre substructures ...

Stoichiometries of remineralisation and denitrification in global biogeochemical ocean models [PDF]
, 2009 Since the seminal paper of Redfield (1934), constant stoichiometric elemental ratios linking biotic carbon and nutrient fluxes are often assumed in marine biogeochemistry, and especially in coupled biogeochemical circulation models, to couple the global ...

Oxydation de Fe2+ par O3 en réacteur semi-continu parfaitement agité
CHIMIA, 1972 Ferrous ion oxidation by ozonised air was carried out in a laboratory well-mixed semi-flow batch reactor. Ozone transfer is shown to proceed according to Astarita’s fast reaction regime. Experimental data are compared to figures obtained by means of the
