Open Access research with a real impact on health...

The Strathprints institutional repository is a digital archive of University of Strathclyde's Open Access research outputs. Strathprints provides access to thousands of Open Access research papers by Strathclyde researchers, including by researchers from the Physical Activity for Health Group based within the School of Psychological Sciences & Health. Research here seeks to better understand how and why physical activity improves health, gain a better understanding of the amount, intensity, and type of physical activity needed for health benefits, and evaluate the effect of interventions to promote physical activity.

Abstract

It has been shown that the polarized Raman scattering method previously developed for quantitative analysis of molecular orientation in polyethylene can be applied to polysulfone hollow fibre membranes. The orientation parameters for the in-plane vibration of the benzene ring in the active layers of the membranes were determined for different processing conditions of the fibres. The results reported here confirm the fact, revealed previously by IR spectroscopy, that the spinning of membrane fibres at high shear rates may induce anisotropy at the molecular level in the active layer.
