The Analytical and Surface Chemistry Program in the Division of Chemistry makes this Career award to the State University of New York at Binghamton to study nanoparticle-structured materials and their sensing applications. With this award, Professor Chuan-Jian Zhong will investigate mediator-template pathways as a general strategy for assembling nanoparticles. Factors that control the size, shape, and interparticle spatial properties of assembled units will be assessed, and applications of the materials in chemical sensing will be explored. Initial focus will be on thioether mediators and tetraalkylammonium templates for the assembly of metal, alloy and oxide nanoparticles. The project will examine a variety of mediator and template systems by manipulating functional groups and chain lengths. The PI will also develop new course modules centered on nanoscale-chemistry for integration into the undergraduate and graduate curriculum and provide summer research opportunities to local high school teachers and students.Strategies based on mediator-template chemistry will be developed for assembling nanoparticles into different shapes (e.g., spherical, cylindrical, cubic, hexagonal, etc.) and sizes. Factors essential to controlling the separation distances between nanoparticles and the dimensions of assembled units on scales ranging from several nanometers to a few micrometers will be identified. The materials will be employed for use in gas and microfluidic sensing devices. The research and education plan will train teachers and provide hands-on experiences for students at the high school, undergraduate and graduate levels that develop cutting-edge technological skills.

化学系的分析和表面化学项目将此职业奖授予位于宾厄姆顿的纽约州立大学，以研究纳米颗粒结构材料及其传感应用。 有了这个奖项，Chuan-Jian Zhong教授将研究介体-模板途径作为组装纳米颗粒的一般策略。 控制组装单元的大小，形状和颗粒间空间特性的因素将被评估，并将探索材料在化学传感中的应用。 最初的重点将是硫醚介体和四烷基铵模板的组装金属，合金和氧化物纳米粒子。 该项目将通过操纵官能团和链长来检查各种介体和模板系统。 PI还将开发以纳米尺度化学为中心的新课程模块，以整合到本科和研究生课程中，并为当地高中教师和学生提供暑期研究机会。将开发基于介体模板化学的策略，用于将纳米颗粒组装成不同形状（例如，球形、圆柱形、立方体、六边形等）和尺寸。 控制纳米颗粒之间的分离距离和组装单元的尺寸范围从几纳米到几微米的尺度上的重要因素将被确定。 这些材料将用于气体和微流体传感设备。 研究和教育计划将培训教师，并为高中、本科和研究生提供实践经验，以发展尖端技术技能。
