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...

New zwitterionic cellulose beads

The design and synthesis of polysaccharide-based materials utilizing a systematic approach is essential to develop sustainable and biodegradable value added products. In this work, new zwitterionic cellulose beads of desired size range...

Topochemical characterisation of sugar cane internodes

Biomass pretreatments and subsequent conversion to fuels and materials involve a multitude of topochemical interactions. Detailed knowledge about changes in surface composition of biomass caused by pretreatments allows tailoring of biomass processing...

Layered double hydroxides decorated with Au-Pd nanoparticles

MgZnAl-Cl layered double hydroxides were prepared by co-precipitation method and further used as support to immobilize gold-palladium (Au-Pd) bimetallic nanoparticles by colloidal sol immobilization method. These materials were characterized by XRD, FT-IR,...

Photocrosslinking of cellulose fibres

Photoresponsive pulp fibers are prepared by self‐assembly of photoactive cationic cellulose derivatives with pulp fibers in aqueous environment. Photoactive groups of the derivatives undergo 2π + 2π cycloaddition reaction under UV‐light irradiation. Fast photocrosslinking...
