Blocking of the interfaces of polymeric ion sensors - implications for novel sensor applications. Control of the transmembrane fluxes of polymeric ion sensors represents a paradigm shift that has revolutionised the use of these analytically important devices. This project will develop and characterise innovative methods for controlling these fluxes by using blocked interfaces, and this has important ramifications for the development of robust and reliable sensors, as well as novel biosensors.

Composite cathode Materials for Lithium Ion Battery Using Chemical Coating Technique. Commercial Li-ion batteries have LiCoO2 as a cathode material due to its excellent cycle stability and rate capability. However, cobalt is a relatively rare and very expensive transition metal, so attention has been focussed on LiMn2O4 with a view to taking advantage of its low cost and environmentally friendly nature compared to LiCoO2. The aim of this develop new composite cathode materials by using a LCo02. ....Composite cathode Materials for Lithium Ion Battery Using Chemical Coating Technique.

Active polymer surfaces for control of fluid movement. The realisation of a diverse array of remote or portable chemical/biological monitoring systems depends on the development of low power fluid management protocols. The use of appropriate conducting polymer surfaces should enable this to occur. We envisage the integration of these fluid management platforms into portable, remote autonomous monitoring systems for environmental industrial and biomedical applications.
