项目摘要

This grant provides support for the acquisition and development of a fast confocal polarizing microscope for liquid crystal (LC) materials research and education at Kent State University. The goal of this project is to expand the recently developed technique of three-dimensional (3D) non-destructive imaging of orientational order into the time domain of real-time scanning to study processes at the millisecond time scale with spatial resolution of 1 micrometer. This new microscope will significantly sharpen the insight of researchers and educators into the complex word of molecular arrangements and their collective dynamics in modern materials and is of great fundamental and applied interest. With high speed imaging it will be indispensable in characterization of structure, properties, and performance of new materials such as LC-colloidal and LC-polymer composites, photonic crystals, biosensors, as well as the traditional materials in complex geometries (for example, LCs with 3D director defects). As many of these materials are new and not well studied, the instrument will bring discoveries of fundamental properties. It will be of great help in development of practical devices such as LC displays, beam steering devices and optical switches. Using this microscope in the development of real-time bacterial detection would be a contribution to the safety and health of the public. The instrument will be installed at the Liquid Crystal Institute (LCI), Kent State University (KSU), a recognized center with well-developed infrastructure combining fundamental and applied research with strong industrial partnership program and with strong educational programs at all levels. Graduate and undergraduate students in physics, chemistry, biology and interdisciplinary programs will benefit, as will undergraduate summer students and K-12 students involved in outreach programs. This new capability will allow the educators to demonstrate the physical essence of fundamental phenomena in modern materials and devices.
该补助金为肯特州立大学用于液晶(LC)材料研究和教育的快速共焦偏振显微镜的获得和开发提供支持。该项目的目标是将最近开发的三维(3D)非破坏性成像技术的取向顺序扩展到实时扫描的时域,以研究在毫秒时间尺度上的过程,空间分辨率为1微米。 这种新的显微镜将大大提高研究人员和教育工作者对现代材料中分子排列及其集体动力学的复杂世界的洞察力,具有重要的基础和应用价值。通过高速成像,它将在表征新材料的结构,性质和性能中不可或缺,如LC-胶体和LC-聚合物复合材料,光子晶体,生物传感器,以及复杂几何形状的传统材料(例如,具有3D指向矢缺陷的LC)。由于这些材料中有许多是新的,没有得到很好的研究,该仪器将带来基本性质的发现。这对液晶显示器、光束控制器、光开关等实用器件的研制具有重要的指导意义。使用这种显微镜进行实时细菌检测将有助于公众的安全和健康。该仪器将安装在肯特州立大学(KSU)的液晶研究所(LCI),该中心是一个公认的中心,拥有完善的基础设施,将基础和应用研究与强大的工业合作伙伴计划以及各级强大的教育计划相结合。 物理,化学,生物和跨学科课程的研究生和本科生将受益,参与外展计划的本科暑期学生和K-12学生也将受益。这种新的能力将使教育工作者能够展示现代材料和设备中基本现象的物理本质。
