Interfacial chemical and transport kinetics in aggressive environments

拟议的研究包括实验和计算研究，以发展对电离辐射或类似侵袭性化学环境中金属氧化物-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，化学反应和传输在每一个均相和那些在或越过界面是强烈相互依赖的，往往是协同的。尽管多相动力学系统具有重要的工业意义，但这种协同作用实际上被忽视了。将应用广泛的方法，包括单个反应和综合化学系统的研究，以及使用有限元方法开发多相动力学模型。拟议中的研究将有一系列工业应用：开发用于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.
