Extensional rheometry of cellulose ether solutions: flow instability

Journal Article
Vadodaria, S. S., & English, R. J. (2015)
Extensional rheometry of cellulose ether solutions: flow instability. Cellulose, 23(1), 339-355. https://doi.org/10.1007/s10570-015-0838-1
Capillary breakup extensional rheometry of semi-dilute hydroxyethyl cellulose (HEC) solutions was performed under several step-stretch conditions. The resulting parameters, i....

The water vapor sorption behavior of natural fibers

Journal Article
Hill, C. A. S., Norton, A., & Newman, G. (2009)
The water vapor sorption behavior of natural fibers. Journal of Applied Polymer Science, 112(3), 1524-1537. https://doi.org/10.1002/app.29725
The water vapor sorption behavior of a range of natural fibers (jute, flax, coir, cotton, hemp, Sitka spruce) has been studied. The data was analyzed using the Hailwood Horrob...

Brownian Dynamics Simulations of Associating Diblock Copolymers

Journal Article
Cass, M. J., Heyes*, D. M., & English, R. J. (2007)
Brownian Dynamics Simulations of Associating Diblock Copolymers. Langmuir, 23, 6576-6587. https://doi.org/10.1021/la063210j
A novel coarse-grained computational model for associating polymers is proposed that is based on a Gaussian “blob” representation of the polymer chains. The model allows a lar...
