Aqueous micellar solutions and gels of the diblock copolymer E398B19 (E = oxyethylene, B = oxybutylene) have been investigated by rheology and small-angle neutron scattering (SANS) in the liquid, soft gel, and hard gel phases. Rheology experiments w... Read More about SANS and Rheology Study of Aqueous Solutions and Gels Containing Highly Swollen Diblock Copolymer Micelles.

Measurements of the Cavitation Threshold of Liquids Under Dynamic Stressing by Pulses of Tension (2002)
Presentation / Conference Contribution
Williams, P. R. W., & Williams, R. (2002, February). Measurements of the Cavitation Threshold of Liquids Under Dynamic Stressing by Pulses of Tension. Presented at NATO Advanced Research Workshop on Liquids Under Negative Pressure

This paper addresses discrepancies between the results of different measurements of the effective tensile strength F(F c ) of liquids, in experiments in which a pulse of tension (or ’negative pressure’) is created by the reflection of a pressure puls...
