9314129 Reiss This three-year award supports U.S.-France cooperative research in theoretical chemistry between Howard Reiss of the University of California, Los Angeles and Pierre Schaaf of the Institut Charles Sadron in Strasbourg, France. The objective of their research is to use newly developed methods of optical microscopy to study the deposition and adsorption of colloid particles on various surfaces, for example, melamine particles on silica surfaces. They plan experiments on particle deposition, kinetic theory, the radial distribution function, and especially, the fluctuation of particle density over surfaces. The U.S. investigator brings to this project considerable expertise in theoretical chemistry, especially in the area of colloid particles. This is complemented by the French experimentalist who developed a method to measure fluctuation density. They will be involved with theoretical aspects of the project as well. The deposition of particles and fluctuation of particle density are of considerable importance in science and technology, and of particular interest to the biochemistry field, where the focus has been on the adsorption of proteins on surfaces. ***

9314129 Reiss这一为期三年的奖项支持加州大学洛杉矶分校的Howard Reiss和法国斯特拉斯堡Charles Sadron研究所的Pierre Schaaf在理论化学方面的美法合作研究。他们的研究目的是使用新开发的光学显微镜方法来研究胶体颗粒在各种表面上的沉积和吸附，例如三聚氰胺颗粒在二氧化硅表面的沉积和吸附。他们计划进行粒子沉积、动力学理论、径向分布函数，特别是表面上粒子密度波动的实验。这位美国研究人员为这个项目带来了理论化学方面的大量专业知识，特别是在胶体粒子领域。这一点得到了法国实验学家的补充，他开发了一种测量波动密度的方法。他们还将参与该项目的理论方面。颗粒的沉积和颗粒密度的波动在科学和技术中具有相当重要的意义，尤其是生物化学领域，其重点一直是蛋白质在表面的吸附。***
