Optical microscopy is a common technique for the examination of small objects under magnification.  Polarized optical microscopy makes use of polarized light, instead of normal light, to study samples.  The polarized optical microscope with heating stage will be used to study the nature of new liquid crystalline materials as well as microcrystalline solids.  Both of these types of materials are birefringent: the transmission of polarized light through the sample depends on the orientation of the sample.  This phenomenon arises because the molecules that make up crystalline solids and liquid crystalline are ordered and oriented in specific directions.  Birefringence makes polarized optical microscopy an important tool for studying these types of ordered materials.  It can provide information about the crystal form and degree of crystallinity in solid materials, and it can allow the identification of different types of liquid crystal phases by virtue of the textural features observed under the microscope. This equipment will be used to support a research program that focuses on the preparation of new liquid crystalline and crystalline materials that are assembled using reversible chemical bonds.  The primary motivation for this research program is to further understand how molecules self-assemble and to control this self-assembly process.  A second goal of this innovative program is to make materials with potential applications in areas such as hydrogen storage, catalyzing chemical reactions, liquid crystal displays, and solar cells.

光学显微镜是一种常用的技术，用于在放大倍率下检查小物体。偏振光学显微镜使用偏振光而不是正常光来研究样品。带加热台的偏振光学显微镜将用于研究新的液晶材料和微晶固体的性质。这两种材料都是双折射的：偏振光通过样品的透射率取决于样品的取向。这种现象的出现是因为组成结晶固体和液晶的分子是有序的，并且在特定的方向上取向。双折射使偏振光显微镜成为研究这些类型的有序材料的重要工具。它可以提供有关固体材料中的晶体形式和结晶度的信息，并且它可以允许借助于在显微镜下观察到的纹理特征来识别不同类型的液晶相。该设备将用于支持一项研究计划，该计划的重点是制备利用可逆化学键组装的新型液晶和晶体材料。该研究计划的主要动机是进一步了解分子如何自组装并控制这种自组装。组装过程。这个创新计划的第二个目标是制造具有潜在应用领域的材料，例如储氢，催化化学反应，液晶显示器和太阳能电池。
