Cellulose nanofibrils (CNF) are cellulose nanomaterials with desirable properties and offer great potentials to be applied in diverse fields. While various pre-treatments have been studied with the aim of reducing the intensity of mechanical fibrilla...

In this study, pulped cellulose fibres were pre-treated with aqueous morpholine prior to mechanical disruption in the production of cellulose nanofibrils (CNF). The properties of the morpholine pre-treated CNF (MCNF) were closely compared with CNF ob...

A new instrument, the virtual gap rheometer (VGR) for the determination of dynamic shear moduli (and mechanical relaxation spectra therefrom) at frequencies above 100 Hz is described. Several features of the VGR which make it particularly suited to t... Read More about Rheological spectroscopy of concentrated colloidal dispersions.
