Interfacial chemical and transport kinetics in aggressive environments

拟议的研究涉及实验和计算研究，以发展在电离辐射或类似的侵蚀性化学环境中的金属氧化物-水和离子液体（IL）-水界面现象的基本理解。 在这样的动态环境中，每个均相中的化学反应和运输以及在界面处或穿过界面的化学反应和运输是强烈相互依赖的，并且通常是协同的。 多相动力学系统的这种协同相互作用尽管在工业上很重要，但实际上却被忽视了。 一个广泛的方法将适用于涉及个别反应和综合化学系统的研究，并使用有限元法的多相动力学模型的发展。 拟议的研究将有一系列工业应用：开发先进核燃料循环和废物储存和处理的新型分离技术，以及水、石油和天然气管道等系统的微生物腐蚀。

The proposed research involves experimental and computational studies to develop a fundamental understanding of metal oxides-water and ionic liquid (IL)-water interfacial phenomena in ionizing irradiation, or similarly aggressive chemical environments. In such dynamic environments, chemical reactions and transport in each homogeneous phase and those at or across the interface are strongly inter-dependent, and often synergistic. This synergistic interaction of multiphase kinetic systems has been practically ignored despite its industrial importance. A wide ranging approach will be applied involving the study of individual reactions and integrated chemical systems, and the development of multiphase kinetic models using a finite element method. The proposed research would have a range of industrial applications: development of novel separation technologies for advanced nuclear fuel cycles and waste storage and treatment, and microbial corrosion of systems such as water and oil and gas pipes.
