Rheometrical Studies of Blood Clot Formation by Oscillatory Shear, Thromboelastography, Sonoclot Analysis and Free Oscillation Rheometry (2008)
Journal Article
Evans, P. A., Hawkins, K. M., Lawrence, M. J., Williams, P. R., & Williams, R. L. (2008). Rheometrical Studies of Blood Clot Formation by Oscillatory Shear, Thromboelastography, Sonoclot Analysis and Free Oscillation Rheometry. AIP conference proceedings, https://doi.org/10.1063/1.2964777

We report studies of the coagulation of samples of whole human blood by oscillatory shear techniques, including Fourier Transform Mechanical Spectroscopy (FTMS). These techniques are used herein to identify the Gel Point of coagulating blood in terms...

Rheometry and associated techniques for blood coagulation studies (2007)
Journal Article
Evans, P. A., Hawkins, K., Lawrence, M., Williams, R. L., Barrow, M. S., Thirumalai, N., & Williams, P. R. (2008). Rheometry and associated techniques for blood coagulation studies. Medical engineering & physics, 30(6), 671-679. https://doi.org/10.1016/j.medengphy.2007.08.005

This review considers various rheometrical approaches that have been adopted to study blood coagulation, with special reference to the rheological assessment of clotting time and studies of the evolution of viscoelasticity during the course of fibrin...

Cavitation erosion in polymer aqueous solutions (2007)
Journal Article
Brujan, E. A., Al-Hussany, A. F. H., Williams, R. L., & Williams, P. R. (2008). Cavitation erosion in polymer aqueous solutions. Wear, 264(11-12), 1035-1042. https://doi.org/10.1016/j.wear.2007.08.007

We report the results of experiments designed to test the hypothesis that the enhanced levels of extensional viscosity conferred upon a liquid due to a polymer additive substantially mitigate cavitation damage, in addition to substantially increasing...

A study of gelatin gelation by Fourier transform mechanical spectroscopy (2007)
Journal Article
Hawkins, K., Lawrence, M., Williams, P. R., & Williams, R. L. (2008). A study of gelatin gelation by Fourier transform mechanical spectroscopy. Journal of Non-Newtonian Fluid Mechanics, 148(1-3), 127-133. https://doi.org/10.1016/j.jnnfm.2007.05.016

This paper reports the results of experiments which were designed to test the hypothesis that the recording of anomalous values of rheological exponents in the gelation of gelatin may, under some circumstances, be due to inappropriate rheometry. Resu... Read More about A study of gelatin gelation by Fourier transform mechanical spectroscopy.

Rheometrical detection of incipient blood clot formation by Fourier transform mechanical spectroscopy (2007)
Journal Article
Evans, P. A., Hawkins, K., Williams, P. R., & Williams, R. L. (2008). Rheometrical detection of incipient blood clot formation by Fourier transform mechanical spectroscopy. Journal of Non-Newtonian Fluid Mechanics, 148(1-3), 122-126. https://doi.org/10.1016/j.jnnfm.2007.04.020

We report a study of the coagulation of whole blood by oscillatory shear Fourier transform mechanical spectroscopy. The results include the first identification of the Gel Point of coagulating blood in terms of the Chambon–Winter Gel Point criterion...

New techniques in sol–gel characterisation – mechanical measurements and fractal characteristics (2001)
Journal Article
Williams, P., Williams, R. L., Jones, R., Al-Hussany, A., & Ravji, S. (2001). New techniques in sol–gel characterisation – mechanical measurements and fractal characteristics. Journal of Non-Crystalline Solids, 293-295, 731-745. https://doi.org/10.1016/S0022-3093%2801%2900852-3

We report theoretical and experimental work which demonstrates how the viscoelastic dispersion of shear waves may be exploited in studies of the rheological properties of systems such as `critical-gels' – systems at the gel point. At the gel point a... Read More about New techniques in sol–gel characterisation – mechanical measurements and fractal characteristics.
