International Journal of Biological Macromolecules, 135, 462-471. https://doi.org/10.1016/j.ijbiomac.2019.05.194

There is an increased interest on changing the synthetic based materials to biodegradable ones, especially with natural polymers, polysaccharides or proteins. In this research we prepared bio-nanocomposite formulations with different component concen...

High-shear rate rheometry of micro-nanofibrillated cellulose (CMF/CNF) suspensions using rotational rheometer (2018)
Journal Article
Vadodaria, S. S., Onyianta, A. J., & Sun, D. (2018). High-shear rate rheometry of micro-nanofibrillated cellulose (CMF/CNF) suspensions using rotational rheometer. Cellulose, 25(10), 5535-5552. https://doi.org/10.1007/s10570-018-1963-4

Suspensions of cellulose micro- and nanofibrils are widely used in coatings, fibre spinning, 3D printing and as rheology modifiers where they are frequently exposed to shear rates > 104 s−1, often within small confinements. High-shear rate rheologica... Read More about High-shear rate rheometry of micro-nanofibrillated cellulose (CMF/CNF) suspensions using rotational rheometer.

The water vapor sorption behavior of a galactomannan cellulose nanocomposite film analyzed using parallel exponential kinetics and the Kelvin-Voigt viscoelastic model. (2013)
Journal Article
Keating, B. A., Hill, C. A. S., Sun, D., English, R., Davies, P., & McCue, C. (2013). The water vapor sorption behavior of a galactomannan cellulose nanocomposite film analyzed using parallel exponential kinetics and the Kelvin-Voigt viscoelastic model. Journal of Applied Polymer Science, 129, 2352-2359. https://doi.org/10.1002/app.39132

Nanocomposite films have been developed where a galactomannan (guar) matrix was reinforced with cellulose nanowhiskers and plasticized using sorbitol. The properties of these films were compared with films made from guar only. The films were examined...
