High-consistency enzymatic fibrillation (HefCel) – a cost-efficient way to produce cellulose nanofibrils (CNF)

Kangas H., Pere J., Qvintus P., VTT Technical Research Centre of Finland Ltd., FI

Cellulose nanofibrils (CNF) are promising bio-based materials for numerous applications, either as replacement of oil-based materials in existing products, potentially with added functionality, or in generating completely new materials and products. The production of material [...]

Abuse Prevention by Controlled Release of Opioids from Micro to Nano-structured Silica Xerogel Delivery Systems

Toworfe G., Anku C., Radin S., Zeiger A., Ducheyne P., Flowers Sch of Technology & Management, DE

This study proposes that release concentrations, of opioid, not exceeding therapeutic target levels can be achieved by incorporating the dosage in a nano-structurally optimized delivery material.

Allyl, glycidyl methacrylate and cyclodextrin-modified nanocelluloses. Preparation, characterisation and adsorption-release specific properties

Vismara E., Zarattini M., Bernardi A., Nanni D., Bertini S., Freire C., Politecnico di Milano, IT

Advances in the chemical modification of nanocelluloses have been recently reviewed by Youssef Habibi.1 Our work aims to enlarge the number of nanocellulose chemical modifications and broaden the horizon of nanocellulose applications. Oxidized and hydrolyzed [...]
