9624562 Chaudhuri Description: This award supports a US-Indo cooperative project between US scientists, Drs. Brij Moudgil, postdoctoral fellow Michael L. Free, Department of Materials Science and Engineering, University of Florida, and Drs. N.C. Chaudhuri, Pradip of the Tata Research Development & Design Centre (TRDDC), Pune, India. The objective of this research is to understand the basic mechanism involved in selective adsorption of hydroxamate and fatty acid reagents in the iron oxide-titania systems. Physical and surface chemical characterization would involve x-rays, SEM, pore size distribution and electrokinetic measurements. Adsorption, FT-IR and microflotation tests would be conducted to identify the conditions for achieving the desired separation. Selectivity observed would be explained on the basis of conditional stability constants, crystal structure specificity and molecular orbital considerations. It is expected that the fundamental knowledge base generated in this study would be useful in scientific design of reagent schemes for processing of low grade complex ores. Scope: This project allows cooperation between two well known scientists whose capabilities complement each other and who work in institutions with complementary facilities for the proposed research. Dr. Moudgil is the director of the newly established Engineering Research Center for Particle Science and Technology, University of Florida. He has published extensively, including several co-publications with Pradip. The collaboration with Dr. Chaudhuri is new and likely to benefit both institutions. This project meets a number of important objectives of the Division of International Programs, especially the inclusion of a postdoctoral fellow and a new Indian participant in the collaboration.

9624562 Chaudhuri 描述：该奖项支持美国科学家 Drs. Chaudhuri 之间的美印合作项目。 Brij Moudgil，佛罗里达大学材料科学与工程系博士后研究员 Michael L. Free 和博士。 N.C. Chaudhuri，印度浦那塔塔研究开发与设计中心 (TRDDC) 的 Pradip。 本研究的目的是了解氧化铁-二氧化钛系统中异羟肟酸盐和脂肪酸试剂选择性吸附的基本机制。 物理和表面化学表征涉及 X 射线、SEM、孔径分布和动电测量。 将进行吸附、FT-IR 和微浮选测试，以确定实现所需分离的条件。 观察到的选择性将根据条件稳定性常数、晶体结构特异性和分子轨道考虑因素进行解释。 预计本研究中生成的基础知识库将有助于科学设计低品位复杂矿石加工的试剂方案。 范围：该项目允许两位知名科学家之间的合作，他们的能力相互补充，并且在具有互补设施的机构中工作，以进行拟议的研究。 Moudgil博士是佛罗里达大学新成立的粒子科学与技术工程研究中心的主任。 他发表了大量著作，包括与普拉迪普合作出版的多本著作。 与 Chaudhuri 博士的合作是新的，并且可能使两个机构都受益。 该项目满足了国际项目部的许多重要目标，特别是在合作中纳入了一名博士后研究员和一名新的印度参与者。
