Advances in the development of materials having desired properties provide the basis of future technologies. Many advances are dependent on synthesis and careful characterization. This grant provides support for an X-ray powder diffractometer for use in research at UCLA on the development of new materials that address several areas of need including chemical control of nanostructured inorganic materials; nitrides; antiferroelectric liquid crystals; and mesostructured thin films. This new instrument will provide rapid data collection capabilities important for dynamic studies of sample reactions as a function of temperature. This new instrument provides for low angle measurements, important for structure measurements, and simultaneous collection of low and high angle X-ray scattering data. The research topics include the synthesis of Zintl phases, the control of high temperature phase stability of tetragonal zirconia, development of metathesis routes to nitrides by control of pressure and/or temperature, the design of antiferromagnetic liquid crystals and the design of mesostructured thin films. The new instrument will be used primarily by the UCLA Department of Chemistry and Biochemistry crystallography laboratory.This work has potential benefits in the near and long term: potential to impact fundamental technology related to the synthesis, assembly and characterization of materials with future practical applications and, more immediately, through the training of graduate and undergraduate students. The UCLA Department of Chemistry and Biochemistry will place this instrument in a shared facility, accessible to all graduate students in the department. This department has eleven tenure track women faculty; also, UCLA is able to attract underrepresented students from across the nation. In keeping with the educational mission of the University, trained student technicians and faculty operate the instruments in the X-ray laboratory.

具有所需特性的材料开发的进步提供了未来技术的基础。 许多进步取决于综合和仔细的表征。 该赠款为在UCLA的研究开发新材料的开发中提供了X射线粉末衍射仪的支持，该材料解决了一些需求领域，包括对纳米结构的无机材料的化学控制；硝酸盐；抗纤维液晶；和介质薄膜。该新仪器将提供快速的数据收集能力，对于样品反应随温度的函数的动态研究很重要。 这种新仪器提供了低角度测量，对于结构测量值很重要，并同时收集了低角度和高角度X射线散射数据。 研究主题包括ZINTL阶段的合成，四方氧化锆高温相稳定性的控制，通过控制压力和/或温度通过控制压力和/或温度的氮化途径的开发，抗磁性液晶的设计以及介质结构薄膜的设计。新仪器将主要由UCLA化学和生物化学晶体学实验室使用。这项工作在近期和长期内具有潜在的好处：影响与未来实际应用的材料的综合，组装和表征相关的基本技术，并且更直接地通过对研究生和研究生学生的培训进行培训。 加州大学洛杉矶分校化学和生物化学系将将该工具放置在该系的所有研究生的共享设施中。 该部门有11个任期妇女教师；此外，加州大学洛杉矶分校能够吸引来自全国各地的人数不足的学生。 为了与大学的教育任务保持一致，训练有素的学生技术人员和教职员工在X射线实验室中操作工具。
