9605197 Somasundaran Description: This award is for the US-India Cooperative Research: Dispersion-Flocculation Phenomena in Colloidal Oxide Suspensions at Low Concentrations of Polymers. The collaborators are Dr. P. Somasundaran, Department of Chemical Engineering, Columbia University and Dr. Pradip of the Tata Research, Development & Design Centre, Pune, India. This research will focus on usage of combinations of low polymer concentrations for flocculation of oxide minerals. The motivation stems from novel results obtained from a current project on iron oxide-alumina where at low concentrations of polyacrylic acid, it was found that alumina can be effectively flocculated. The researchers will study the fundamental mechanisms of polymer-polymer, particle-particle and polymer-particle interactions in order reach the goal of this research which is to develop a unified theory of polymeric flocculation. The knowledge gained from this study will help develop strategies for an industrially important and technologically challenging problem--the selective separation of fine particulates in general and oxide suspensions in particular. Scope: This project supports pioneering research at two well regarded laboratories and between scientists with complementary expertise and excellent research track records. Students in both countries will be involved in the research. The project enhances international collaboration in an area of high scientific interest and mutual benefit. The project meets INT objectives. ***

9605197 Somasundaran描述：该奖项授予美国-印度合作研究：低浓度聚合物下胶体氧化物悬浮液中的分散絮凝现象。 合作者是哥伦比亚大学化学工程系的P. Somasundaran博士和印度浦那塔塔研究开发设计中心的Pradip博士。 这项研究将集中在使用低聚合物浓度的组合絮凝氧化物矿物。 动机源于从当前的氧化铁-氧化铝项目中获得的新结果，其中在低浓度的聚丙烯酸下，发现氧化铝可以有效地絮凝。 研究人员将研究聚合物-聚合物，颗粒-颗粒和聚合物-颗粒相互作用的基本机制，以达到本研究的目标，这是发展一个统一的理论聚合物絮凝。 从这项研究中获得的知识将有助于制定一个工业上重要的和技术上具有挑战性的问题-在一般情况下，特别是氧化物悬浮液的选择性分离的战略。 适用范围：该项目支持两个备受推崇的实验室的开创性研究，以及具有互补专业知识和优秀研究记录的科学家之间的研究。 学生 两国都将参与这项研究。 该项目加强了在一个具有高度科学意义和互利的领域的国际合作。 该项目符合INT目标。 ***
