Interfacial Nanofluids

Grant number: DP0880152 | Funding period: 2008 - 2012

Completed

Abstract

The fundamental understanding of Colloid and Surface Chemistry will be significantly enhanced through the understanding of the formation and properties of interfacial nanofluids. In addition, this project will provide the knowledge of the influence of nanofluids on the lubrication and the surface interaction. The future results will likely have great impact on the development of miniature devices, lab-on-a-chip and microfludics or nanofluidics systems, water treatment, minerals processing, the food industries, pumping of fuel and water, and other processes. And the research described in this proposal will help to maintain the high international profile of Australian science in the field of C..
