Determination of Asphaltene Critical Nanoaggregate Concentration Region Using Ultrasound Velocity Measurements
A. Svalova, N. G. Parker, M. J. W. Povey +1
Asphaltenes constitute the heaviest, most polar and aromatic fraction of petroleum crucial to the formation of highly-stable water- in-crude oil emulsions. The latter occur during…
Post-processing of polymer foam tissue scaffolds with high power ultrasound: a route to increased pore interconnectivity, pore size and fluid transport
N J Watson, R K Johal, Y Reinwald +6
We expose thick polymer foam tissue scaffolds to high power ultrasound and study its effect on the openness of the pore architecture and fluid transport through the scaffold. Our a…
Ultrasonic study of the gelation of gelatin: phase diagram, hysteresis and kinetics
N. G. Parker, M. J. W. Povey
We map the ultrasonic (8 MHz) speed and attenuation of edible-grade gelatin in water, exploring the key dependencies on temperature, concentration and time. The ultrasonic signatur…
Longitudinal acoustic properties of poly(lactic acid) and poly(lactic-co-glycolic acid)
N G Parker, M L Mather, S P Morgan +1
Acoustics offers rich possibilities for characterising and monitoring the biopolymer structures being employed in the field of biomedical engineering. Here we explore the rudimenta…
A preliminary study of acoustic propagation in thick foam tissue scaffolds composed of poly(lactic-co-glycolic acid)
N. G. Parker, M. L. Mather, S. P. Morgan +1
The exclusive ability of acoustic waves to probe the structural, mechanical and fluidic properties of foams may offer novel approaches to characterise the porous scaffolds employed…
Temperature dependence of bulk viscosity in water using acoustic spectroscopy
M. J. Holmes, N. G. Parker, M. J. W. Povey
Despite its fundamental role in the dynamics of compressible fluids, bulk viscosity has received little experimental attention and there remains a paucity of measured data. Acousti…
