Topochemical fractionation of lignin and polysaccharides

Topochemical fractionation of lignin and polysaccharides

Sugarcane bagasse is abundant agro-industrial waste that can be potentially utilized as a source of valuable compounds and biopolymers. In the present study, sugarcane bagasse from Brazil was fractionated employing an environmentally...

Ionic Liquids — Promising but Challenging Solvents for Homogeneous Derivatization of Cellulose

In the past decade, ionic liquids (ILs) have received enormous interest as solvents for cellulose. They have been studied intensively for fractionation and biorefining of lignocellulosic biomass, for dissolution of the polysaccharide,...

Buccal discs for oromucosal drug delivery

Mucoadhesive formulations have a wide scope of application for both systemic and local treatment of various diseases. In the case of recurrent aphthous stomatitis, to ensure effective therapy, the concentration of corticosteroids,...

Anionic cellulose beads for drug encapsulation and release

Cellulose beads were prepared from water-based solvent and oxidised by modified Anelli’s reaction at 20– 80∘C80∘C for 2–48 h (Fig. 1). The maximum amount of anionic groups (AGs) was 1.85mmolg−11.85mmolg−1 . The...

Polysaccharide-based polyelectrolyte complexes

Molecular assemblies, namely, polyelectrolyte complexes (PECs) composed of negatively charged xylan-based derivatives and a novel positively charged cellulose derivative (CN+), were used for interfacial modification of wood fibers by charge directed self-assembly....
