Chemical Reactions at Solid/Solution Interfaces and in Aerosols

将进行一项固体/溶液界面研究计划，包括制备定义明确的胶体分散体，研究气溶胶中的化学反应，以及颗粒-颗粒相互作用。将特别强调由一种以上阳离子组成的颗粒的制备和表征。我们将研究固相组成与溶液组成之间的关系。将检查具有不同表面和核心的包覆颗粒，以期开发表面含有高价值组分的颗粒。在不同离子强度的介质中，不同组成、不同尺寸和不同表面电势的颗粒之间的相互作用将从实验和理论上得到检验。%在分析和表面化学的一般领域，这项研究侧重于研究固体/溶液界面和气溶胶中的化学反应。该项目有望扩大我们对胶体粒子的理解。这一研究成果对几项重要技术(如陶瓷、涂料、催化)具有相当大的实际应用价值。

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).
