国家科学基金会-化学和运输系统颗粒和多相过程计划(1415)摘要建议编号：0644789主要研究人员：Kretzschmar，ILonaAffiliation：CUNY City Collesis建议标题：Career：用于三维结构分级自组装的独特功能化纳米颗粒智力优点：本工作中提出的T-结构的合成可以作为等离子体开关的有趣模型系统。颗粒表面的定点修饰，即斑块颗粒，以及随后的分子定向组装，通过为结合能、颗粒浓度和斑块大小的选择提供指导，从而推进了自组装区域。T-Structure组件用作实现分支结构的模型系统，其中包含对三维组件至关重要的元素。此外，片状颗粒还可以用作表面活性剂、传感器和颗粒探测器，以促进对胶体悬浮液和乳状液稳定性的了解。更广泛的影响：CCNY是一家公认的为少数族裔服务的机构，服务于不同的本科生群体，包括西班牙裔(36%)、非裔美国人(30%)、亚裔(23%)和白人(21%)。学生将从分子定向粒子组装领域的积极研究中受益。IREU项目的组织为CCNY本科生提供了接触国际研究的机会。此外，拟议的个人辅导将为女性和少数族裔学生在职业生涯早期提供一个辅导网络。与路易斯-斯托克斯少数族裔参与联盟(LSAMP)的合作将把代表人数不足的群体的学生引导到该计划中。未来的记者、作家和制片人接触纳米技术可能会对我们这个以媒体为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.
