This award supports Professor Asit Ray and a U.S. graduate student from the University of Kentucky to collaborate in chemical engineering research with Professor Gustav Schweiger and others from the Faculty of Mechanical Engineering at the Ruhr University of Bochum, Germany. The objectives of their joint research are to develop techniques for generation of layered particles of precise composition, and to develop techniques for in situ physical and chemical characterization of layered spheres. In particular, they will focus on techniques involving elastic and inelastic (Raman) scattering of light with the goal of developing a technique that combines the two simultaneously for complete quantitative characterization of layered microparticles. The challenge here is the complexity of scattering introduced by the small size of the particles. Progress will require a computational approach based on light scattering theory and controlled experimentation. The success of the effort relies heavily on the complementary expertise of Dr. Ray in elastic scattering techniques and of his German colleague, Dr. Schweiger, in Raman spectroscopy of microparticles. They will also make use of unusual facilities including the specialized Aerosol Laboratory at the University of Kentucky and the state-of-the-art laser spectroscopy laboratory of Dr. Schweiger in Bochum. Better understanding of the formation and behavior of microparticles will have immediate and important applications in many technologies and processes. These include the manufacture of high purity ceramics and thin films, separation technologies related to pollution control and remediation, chemical reaction processes in many industries, and even atmospheric processes and the generation of artificial rain.

该奖项支持Asit Ray教授和一名来自肯塔基州大学的美国研究生与德国波鸿鲁尔大学机械工程学院的Gustav Schweiger教授和其他人合作进行化学工程研究。 他们联合研究的目标是开发生成精确成分的层状颗粒的技术，并开发层状球体的原位物理和化学表征技术。 特别是，他们将专注于涉及光的弹性和非弹性（拉曼）散射的技术，目标是开发一种同时结合这两种技术的分层微粒的完整定量表征。这里的挑战是由颗粒的小尺寸引入的散射的复杂性。 这方面的进展需要一种基于光散射理论和受控实验的计算方法。 这一努力的成功在很大程度上依赖于雷博士在弹性散射技术方面的互补专业知识和他的德国同事施魏格博士在微粒拉曼光谱学方面的互补专业知识。 他们还将利用不寻常的设施，包括肯塔基州大学专门的气溶胶实验室和波鸿Schweiger博士最先进的激光光谱实验室。 更好地理解微粒的形成和行为将在许多技术和过程中具有直接和重要的应用。 其中包括高纯度陶瓷和薄膜的制造，与污染控制和补救有关的分离技术，许多行业的化学反应过程，甚至大气过程和人工降雨的产生。
