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).

固体/溶液界面的研究计划将是 包括制备定义明确的胶体 气溶胶中的化学反应研究， 粒子间的相互作用 将特别强调 置于颗粒的制备和表征 由一个以上的阳离子组成。 的关系 固相的组成与溶液的组成将是 考察 具有不同表面和核的包覆颗粒 将进行检查，以便开发具有 含有高价值成分的表面。 的相互作用 不同成分、尺寸和表面的颗粒之间 将检查不同离子强度介质中的电位 无论是实验上还是理论上。 %%% 在分析和曲面的一般领域， 化学，侧重于研究化学反应， 固体/溶液界面和气溶胶中。 项目 有望扩展我们对胶体粒子的理解。 该研究成果具有相当的实用价值 影响几项重要技术的应用（例如， 陶瓷、油漆、催化）。
