项目摘要

This Faculty Early Career Development Program award to Dr. Sarah Tolbert of the University of California is supported by the Advanced Materials and Processing Program in the Chemistry Division. The focus of the research will be the synthesis of new mesoporous intermetallic Zintl phase clusters, and controlling their assembly, order and orientation using surfactants in solvents. The ultimate goal of the program will be the synthesis of complex periodic structures that contain rigid inorganic nanostructured framework with a wide range of metallic and semiconducting phases. Potential applications of these materials will be in size-selective electrochemical sensors and photovoltaic cells. The educational plan will be to design new experiments in Materials Chemistry for upper-division undergraduates with interdepartmental activities to explore connections between materials and their properties, and to expose students to a variety of materials related approaches and solutions.Nanoclusters with controlled structure, pore size and functions will be prepared for high performance applications in catalysis, electrochemical sensors and electrooptic devices. The teaching part of the award will provide excellent training opportunities to undergraduate and graduate students in different aspects of Materials Chemistry, including synthesis, characterization, study of structure-function relationships and fabrication of optical devices such as light emitting diodes.

该学院早期职业发展计划授予加州大学的Sarah Tolbert博士，由化学系的先进材料和加工计划提供支持。研究的重点将是合成新的介孔金属间化合物Zintl相簇，并在溶剂中使用表面活性剂控制它们的组装、有序和取向。该计划的最终目标将是合成复杂的周期性结构，其中包含具有广泛金属和半导体相的刚性无机纳米结构框架。这些材料的潜在应用将是尺寸选择性电化学传感器和光伏电池。本课程将为高年级本科生设计新的材料化学实验，通过跨部门的活动探索材料与其性质之间的联系，并让学生接触到各种与材料相关的方法和解决方案。具有可控结构，孔径和功能的纳米团簇将为催化，电化学传感器和电光器件的高性能应用做准备。该奖项的教学部分将为材料化学不同方面的本科生和研究生提供极好的培训机会，包括合成，表征，结构-功能关系的研究和发光二极管等光学器件的制造。
