Mécanismes de gonflement et de dissolution des fibres de cellulose [PDF]
, 2007 La cellulose est un polymère semi-cristallin naturel, renouvelable et biodégradable issue principalement des fibres de coton et de bois. Cependant, son utilisation pour des applications techniques est limitée par la structure spécifique des fibres.

Asian Journal of Organic Chemistry, Volume 14, Issue 12, December 2025.We established a metal‐free, late‐stage diversification of terminal alkynes into nitriles using tert‐butyl nitrite (tBuONO). Replacing 2‐picoline N‐oxide with N‐methylmorpholine N‐oxide (NMO) as the oxidant enabled efficient nitrile formation under mild conditions. Abstract The small nucleoside molecule LJ‐4827 exhibited potent kinase inhibition and in

Recent Advances in Stereospecific Transformations of Organoboron Reagents
Transformative Chemistry, Volume 1, Issue 1, December 2025.Enantioenriched boronic esters when activated with organolithiums, can be transformed into boronate complexes that act as chiral organometallic‐type nucleophiles and can engage a wide variety of electrophiles in stereospecific cross‐coupling reactions.

Ethylene glycol assisted intermolecular Pauson-Khand reaction [PDF]
, 2017 The use of ethylene glycol as additive in the N-oxide-promoted intermolecular Pauson-Khand reaction (PKR) has been studied. The addition of 15% ethylene glycol to the reaction mixture consistently increased (from 20% up to 2-4-fold) the reaction ...

SUBSTRATE CHARACTERISTIC ANALYSIS FOR ANAEROBIC DIGESTION: A STUDY ON RICE AND TRITICALE STRAW
BioResources, 2012 Different substrate characteristic analyses have been studied on rice and triticale straw pretreated with NMMO (N-methylmorpholine-N-oxide) prior to biogas production.

Cellulosic materials as biopolymers and supercritical CO2as a green process: chemistry and applications [PDF]
, 2012 In this review, we describe the use of supercritical CO2 (scCO2) in several cellulose applications. The focus is on different technologies that either exist or are expected to emerge in the near future.
