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.

Cellulose swelling and dissolution as a tool to study the fiber structure

, 2006
International audienceThe swelling and dissolution mechanisms of cotton or wood fibers cellulose fibers in aqueous (as N - methylmorpholine N-oxide and water mixtures, or soda solutions) or in ionic liquids are studied.

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.

Water-accelerated organic transformations [PDF]

, 2001
Rather than quenching all reactive intermediates and arresting the reaction, the addition of catalytic or stoichiometric (1-10 equiv.) quantities of H2O to organic and organometallic processes can lead to surprisingly beneficial effects on reaction rate,

Upcycling cotton gin byproducts into bioplastics: A sustainable approach to Co-dissolution of lignin and cellulose using a DES/NMMO binary solvent

Materials Today Sustainability
In this work, a sustainable and efficient approach was developed to address the challenges associated with the dissolution of the entire biomass lignocellulosic components. This was carried out using a deep eutectic solvent (DES) and N-methylmorpholine N-

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.

Metal-organic frameworks as selective or chiral oxidation catalysts [PDF]

, 2014
Since the discovery of Metal Organic Frameworks (MOFs) in the early 1990s, the amount of new structures has grown exponentially. A MOF typically consists of inorganic nodes that are connected by organic linkers to form crystalline, highly porous ...

Direct production of regenerated cellulose films from pretreated corn stover using NMMO/water: Effects of pretreatment and crosslinking on film properties

Industrial Crops and Products
Although the fabrication of regenerated cellulose (RC) films from highly purified cellulose has been extensively studied, few efforts have explored their direct production from chemically pretreated biomass with varying lignin and xylan contents.
