Chemical Reactions at Solid/Solution Interfaces and in Aerosols

本课程将进行固/溶界面的研究，包括制备明确的胶体分散体、研究气溶胶中的化学反应和粒子间的相互作用。特别强调将放在制备和表征粒子组成的一个以上的阳离子。将研究固相组成与溶液组成的关系。将检查具有不同表面和芯的涂覆颗粒，以开发表面含有高价值成分的颗粒。在不同离子强度的介质中，不同组成、大小和表面电位的粒子之间的相互作用将从实验和理论两方面进行研究。在分析化学和表面化学的一般领域，主要研究固/液界面和气溶胶中的化学反应。该项目有望扩展我们对胶体粒子的理解。这项研究的结果对几个重要的技术（如陶瓷、油漆、催化）有相当大的实际应用影响。

A program of study of the solid/solution interface will be performed involving the preparation of well defined colloidal dispersions, studies of chemical reactions in aerosols, and particle-particle interactions. Special emphasis will be placed on the preparation and characterization of particles consisting of more than one cation. The relationship of the composition of the solid phase to that of the solution will be examined. Coated particles having different surfaces and cores will be examined with a view to developing particles with surfaces containing high value components. The interaction between particles of different composition, size and surface potential in media of varying ionic strength will be examined both experimentally and theoretically. %%% The research, in the general area of Analytical and Surface Chemistry, focuses on the study of chemical reactions at solid/solution interfaces and in aerosols. The project promises to extend our understanding of colloidal particles. The outcome of this research has considerable practical applications impacting on several important technologies (e.g. ceramics, paints, catalysis).
