美国国家科学基金会-化学运输系统分部颗粒多相过程计划（1415）摘要提案编号：0644789主要研究员：Kretzschmar，Ilona所属机构：&& CUNY City College提案标题：职业：独特的功能化纳米粒子的分层自组装的三维结构智力优点：在这项工作中提出的T-结构的合成可以作为一个有趣的模型系统的等离子体开关。颗粒表面的位点特异性修饰，即，补丁颗粒和随后的分子定向组装通过提供用于选择结合能、颗粒浓度和补丁尺寸的指导来推进自组装的领域。T型结构组件作为一个模型系统，用于实现包含三维组件的关键元素的分支结构。此外，斑片状颗粒还可以用作表面活性剂、传感器和颗粒探针，以促进对胶体悬浮液和乳液稳定性的理解。更广泛的影响：CCNY是公认的少数民族服务机构，为西班牙裔（36%），非洲裔美国人（30%），亚洲（23%）和白色（21%）学生的多样化本科生群体提供服务。学生将从分子定向粒子组装领域的积极研究中获益。IREU计划的组织为CCNY本科生提供了国际水平的研究机会。此外，拟议的个人辅导将在女学生和少数民族学生的职业生涯早期为他们提供一个辅导网络。与路易斯-斯托克斯少数民族参与联盟（LSAMP）的合作将引导来自代表性不足群体的学生进入该计划。未来的记者，作家和生产者接触到纳米技术可能会对我们的媒体导向的社会产生强烈的影响，并将有助于提高非技术作家对纳米技术的潜在应用和公众舆论对该领域发展的影响的认识。

National Science Foundation - Division of Chemical &Transport Systems Particulate & Multiphase Processes Program (1415)ABSTRACTProposal Number: 0644789Principal Investigator: Kretzschmar, IlonaAffiliation: CUNY City CollegeProposal Title: CAREER: Uniquely functionalized nanoparticles for hierarchical self-assembly of three-dimensional structures Intellectual Merit:The synthesis of T-structures proposed in this work could serve as an interesting model system for a plasmonic switch. The site-specific modification of particle surfaces, i.e., patch particles, and subsequent molecularly directed assembly advance the area of self-assembly by providing guidelines for the choice of binding energies, particle concentrations, and patch sizes. The T-structure assembly serves as a model system for achieving branched structures containing the elements crucial for three-dimensional assembly. Further, the patchy particles may also serve as surfactants, sensors, and particle probes for the advancement of the understanding of colloidal suspensions and emulsion stabilization. Broader Impact: CCNY is a recognized minority-serving institution, which serves a diverse undergraduate student body of Hispanic (36%), African American (30%), Asian (23%), and White (21%) students. The students will profit from the active research in the area of molecularly directed particle assembly. The organization of an IREU program provides CCNY undergraduates with exposure to research at an international level. Further, the individual mentoring proposed will provide female and minority students with a mentoring network early on in their careers. Collaboration with the Louis-Stokes Alliance for Minority Participation (LSAMP) will channel students from underrepresented groups into the program. The exposure of future journalists, writers, and producers to nanotechnology is likely to have a strong impact on our media-oriented society and will help to increase the awareness of non-technical writers to the potential applications of nanotechnology and the effect of public opinion on the development of the area.
