Porous, structurally well-defined anionic nanocapsules with varying charge density: interactions with their environment and with each other

李海伊大学化学系刘天波教授在无机、生物无机和有机金属化学项目的支持下，通过NSF-DFG项目与德国比勒菲尔德大学的Achim m<e:1> ller教授进行了国际合作。该联合研究项目探索新颖的、结构明确的、多孔的溶液阴离子纳米胶囊。这是无机化学和物理化学交叉的一个令人兴奋的新领域。该团队将开发合理的方法来修饰巨大的球形氧化钼纳米胶囊，以便在溶液/组装实验中精确调整电荷密度和内部/外部功能。合作者计划使用各种物理技术来了解阴离子胶囊和小阳离子之间的吸引力，以及纳米胶囊对外部条件变化的反应。这项研究将有助于理解带电纳米粒子和自组装过程之间的强引力。这项研究将对材料科学、合成化学、物理学和生物学等其他领域产生广泛的影响。刘教授和ms . ller将组织一些重要的国际研讨会，与各国的顶尖科学家广泛交流他们的研究成果。还计划通过通俗科学杂志上的文章进行传播。博士后研究员、研究生和本科生将参与丰富美国和德国之间的技术和文化交流。

Professor Tianbo Liu of the Department of Chemistry at Lehigh University is suppoted by the Inorganic, Bioinorganic, and Organometallic Chemistry Program to participate in an international collaboration with Professor Achim Müller of the University of Bielefeld in Germany through the NSF-DFG Program.The joint research project explores novel, structurally well-defined, porous anionic nanocapsules in solution. This is an exciting new area at the intersection of inorganic chemistry and physical chemistry. The team will develop rational methods to modify giant, spherical molybdenum-oxide based nanocapsules so that charge densities and internal/external functionalities can be accurately adjusted for solution/assembly experiments. The collaborators plan to use various physical techniques to understand the attraction between anionic capsules and small cations, as well as the response of the nanocapsules to changes in external conditions. This study will facilitate the understanding of strong attractive forces between charged nanoparticles and self-assembly processes in general. The research will have a broad impact on other fields, such as materials science, synthetic chemistry, physics and biology. Professors Liu and Müller will organize a number of important international symposia to extensively communicate their results with leading scientists from various countries. Dissemination is also planned via articles in popular science magazines. Postdoctoral associates and graduate and undergraduate students will be involved in enriching technical and cultural exchanges between the US and Germany.
