Cellulose biotemplate for inorganic porous networks

Cellulose biotemplate for inorganic porous networks

Synthesis of porous network structures of layered double hydroxides (LDH) has been studied using microcrystalline cellulose (MCC) as a hard template. LDH was synthesized using cellulose as biotemplate and post treated by...

Antimicrobial hybrid cellulose-lignin beads

In the present study, cellulose-lignin beads were prepared using pretreated dissolving grade-pulp and extracted from birch wood hydrotropic lignin as starting materials. The preparation involved dissolution of both polymers in environmentally friendly...

Tailored cellulose beads for drug release

In the frame of this work, we have investigated drug entrapping and release abilities of new type of porous cellulose beads (CBs) as a spherical matrix system for drug delivery. For that...

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....

Nanofibrous graft for bone tissue engineering

Nanofibers coated onto the bone implant as a dual-layered material has supported the regeneration of bone cells suitable for bone tissue engineering. Herein, we report the electrospinning of Poly(3-Hydroxybutyric acid)-Poly(N-vinylpyrrolidone) NanoFibrous Matrix...

Reactive interfaces on fibres

Cellulose fibres have poor reactivity and limited potential for surface engineering with advanced chemical functionalization in water. In this work, cellulose fibres were decorated with azide functions by charge-directed self-assembly of a...
