CAREER: From Surface to Solution: Bond Scission and Templating for Fabrication of Nanoscale Structures

利伯曼该项目旨在开发将化学图案化表面用作纳米粒子生长模板的方法。自混合单层中的微接触打印将用于固定多层材料的生长。通过切断合成到锚定自组装单分子层中的容易断裂的键，颗粒将从衬底上分离出来，保留完整的化学图案表面以供进一步使用--一台生成颗粒的同上机器。我们的目标也是能够产生新的粒子形貌，并复制溶液中的粒子。最初，材料的重点将是层状金属磷酸盐，由密集排列的有机柱基共价连接的层叠金属磷酸盐片层组成，其中分层和再生长的循环可能导致纳米颗粒的指数放大，类似于生化系统中已知的过程。将研究主题与强调非理科专业化学和公共政策的教育主题相结合，作为支持材料被开发和测试，并纳入化学课程。%这项涉及材料化学基础研究的研究和教育针对几个环境领域的技术应用，以说明材料化学在实践中的应用--在工业、政府和法院--向学生展示它是如何在现实世界中使用的。*

9875788LiebermanThis project aims to develop ways to use chemically patterned surfaces as templates for the growth of nanoscale particles. Microcontact printing in a self-asssembled monolayer will be used to anchor the growth of multilayer materials. The particles will be detached from the substrate by severing easily cleaved bonds that have been synthesized into the anchoring self-assembled monolayer, leaving intact the chemically patterned surface for further use - a ditto machine for generating particles. The goal is also to be able to generate novel particle topographies and to make copies of particles in solution. Initially, the materials focus will be on layered metal phosphonates consisting of stacked sheets of metal phosphonates covalently linked by densely packed organic pillaring groups where a cycle of delamination and regrowth could lead to exponential amplification of the nanoparticles similar to processes known to occur in biochemical systems. The integration of research themes together with a focus on educational themes that emphasize chemistry and public policy for non-science majors will be developed and tested as supporting materials to be incorporated into the chemistry curriculum.%%%This research and education involving fundamental investigations of materials chemistry is directed at technological applications in several environmental areas to illustrate materials chemistry in practice - in industry, government, and the courts - to show students how it is used in the real world.***
