Topochemical treatment of sugar cane bagasse for enzymatic hydrolysis of sugars

Topochemical treatment of sugar cane bagasse for enzymatic hydrolysis of sugars

In this work, dilute alkaline and alkaline peroxide pretreatments were conducted in comparison with hydrotropic pretreatment to improve the delignification of bagasse prior to enzymatic hydrolysis. The surface chemical composition of bagasse...

Surfaces of chitosan treated viscose fibres

Time-of-flight secondary ion mass spectrometry (ToF-SIMS) was employed to analyse cellulose viscose fibres treated with different chitosan-based solutions. The analysis reports several new features in the TOF-SIMS spectra for systems with various...

In Situ Hybridization of Pulp Fibers Using Mg-Al Layered Double Hydroxides

Inorganic Mg2+ and Al3+ containing layered double hydroxide (LDH) particles were synthesised in situ from aqueous solution onto chemical pulp fibers of pine (Pinus sylvestris). High super saturated (hss) solution with sodium...

Controlled depolimerization of cellulose via HyCellSolv

The degree of polymerization of cellulose is very relevant for physical and chemical properties of highly engineered biomaterials. The ability to control the level of depolymerisation to a final specific value opens...

Hydrotropic extraction of birch lignin

In this work an environmentally friendly hydrotropic process was used to extract lignin from industrial birch wood chips. Two hydrotropic treatments were performed, a conventional and a modified process. The lignins were...

Multi-technique surface characterization of bio-based films from sisal cellulose and its esters

Bio-based films were prepared from LiCl/DMAc solutions containing sisal cellulose esters (acetates, butyrates and hexanoates) with different degrees of substitution (DS 0.7–1.8) and solutions prepared with the cellulose esters and 20 wt%...

Supramolecular design of cellulose hydrogel beads

In the present study, we report the supramolecular design of cellulose-sulfonate hydrogel beads by blending water soluble sodium cellulose ethyl sulfonate (CES) with the pretreated cellulose in sodium hydroxide-ureawater solvent system at...
