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.***

9875788 Lieberman该项目旨在开发使用化学图案化表面作为纳米级颗粒生长模板的方法。 自组装单层中的微接触印刷将用于锚多层材料的生长。 通过切断已经合成到锚定自组装单层中的容易裂解的键，颗粒将从基底分离，留下完整的化学图案化表面以供进一步使用-用于产生颗粒的同上机器。 我们的目标也是能够产生新的颗粒形貌，并在溶液中复制颗粒。 最初，材料的重点将是层状金属膦酸盐，其由通过密集堆积的有机柱撑基团共价连接的金属膦酸盐的堆叠片组成，其中分层和再生长的循环可能导致纳米颗粒的指数扩增，类似于已知在生化系统中发生的过程。 将研究主题与强调化学和非科学专业公共政策的教育主题相结合，并将其作为支持材料进行开发和测试，以纳入化学课程。这种研究和教育涉及材料化学的基础研究是针对技术应用在几个环境领域，以说明材料化学在实践中-在工业，政府和法院-向学生展示它是如何在真实的世界中使用。
