0091547SomasundaranThis two-year award, which supports U.S.-Italy cooperative research on interactions of nanoparticles of dendrimers/liposomes with polymers and surfactants, involves Ponisseril Somasundaran of Columbia University and M.F. Ottaviani of the Institute of Chemical Sciences in Urbino, Italy. The objective of their research is to enable the use of electron spin resonance to monitor conformation of polymers and surfactants at interfaces. The U. S. principal investigator brings to this collaboration his group's expertise in identifying the best conformation of polymers and proteins for determining the interactions between nanoparticles and dendrimers with surface active species. The US co-PI provides experience with applied supramolecular structure-function and structure-reactivity relationships toward understanding the behavior of adsorption at interfaces. This work is complemented by the Italian investigator's expertise in the use of electron spin resonance probes for examination of adsorption at interfaces. The results of this research are expected to contribute to knowledge of the behavior of vital industrial systems.

0091547SOMASUNDARANITHIS两年奖，该奖项支持美国质的合作研究，涉及哥伦比亚大学和硕士的Ponisseril Somasundaran，涉及树枝状聚合物/脂质体与聚合物和表面活性剂的纳米颗粒相互作用。意大利乌尔比诺化学科学研究所的Ottaviani。 他们研究的目的是使使用电子自旋共振来监测接口处的聚合物和表面活性剂的构象。美国首席研究人员将这一合作带来了他的小组在确定聚合物和蛋白质的最佳构象方面的专业知识，用于确定纳米颗粒与树突聚合物与表面活性物种之间的相互作用。 美国Co-Pi提供了用于理解接口上吸附行为的超分子结构功能和结构反应关系的经验。 意大利研究者在使用电子旋转谐振探针方面的专业知识以检查接口处的吸附。这项研究的结果预计将有助于了解重要工业系统的行为。
