0076014Mays授予阿拉巴马大学伯明翰分校(UAB)购买ALV/DLS/SLS-5022F测角仪系统。这是一种研究级仪器，能够同时执行静态和动态光散射测量，并具有雪崩光电二极管探测器，允许高计数强度，同时使用廉价的低功率(22 MW)氦-霓虹灯。它还具有非常大的可用角度范围(12度至155度)、从亚环境到90摄氏度的温度控制，并提供轻松对准和卓越的软件功能。该仪器将为UAB在聚合物材料领域的研究和教育提供新的基础设施。从研究角度来看，该仪器在表征UAB合成的各种线型和支化聚合物、共聚物和树枝状大分子的相对分子质量、回转半径、维里系数和流体动力学半径方面将是非常有价值的。它还将为表征聚合物胶束提供一个强有力的手段，这是目前化学系感兴趣的一个研究领域。此外，该仪器将允许UAB为生物化学和聚合物化学课程开发新的教学实验室，从而使每年约40名学生接触到利用光散射来表征天然和合成大分子。*该仪器奖授予阿拉巴马大学伯明翰分校，以表彰购买用于表征聚合物、聚合物胶束和树枝状大分子的最先进的光散射仪器。该仪器将为UAB在聚合物材料领域的研究和教育提供新的基础设施。从研究角度来看，该仪器在表征在UAB合成的各种线型和支化聚合物、共聚物和树枝状大分子的质量和尺寸方面将是非常有价值的。它还将为表征聚合物胶束提供一个强有力的手段，这是目前化学系感兴趣的一个研究领域。总体而言，UAB化学系约30名研究科学家的新的和现有的研究计划将受到有利的影响。此外，该仪器将允许新的生物化学和聚合物化学课程的教学实验室，从而使每年约40名学生接触到使用光散射来表征天然和合成的大分子。%

0076014MaysAn award is made to the University of Alabama at Birmingham (UAB) to purchase a ALV/DLS/SLS-5022F goniometer system. This is a research grade instrument capable of performing simultaneous static and dynamic light scattering measurement and features an avalanche photodiode detector that allows high counting intensity while employing an inexpensive, low power (22mW) Helium-Neon laser. It also features a very large useable angular range (12 degrees to 155 degrees), temperature control from sub-ambient to 90 degrees C, and offers ease of alignment and superior software features. This instrument will provide new infrastructure at UAB for research and education in the area of polymeric materials. From a research perspective, this instrument will be extremely valuable in characterizing molecular weights, radii of gyration, virial coefficients, and hydrodynamic radii of various linear and branched polymers and copolymers and dendrimers being synthesized at UAB. It also will provide a powerful means for characterizing polymer micelles, a research area of intense current interest in the Department of Chemistry. In addition, this instrument will allow UAB to develop new teaching laboratories for both Biochemistry and Polymer Chemistry classes, thus exposing approximately forty students annually to the use of light scattering for characterizing natural and synthetic macromolecules.***This instrumentation award to the University of Alabama Birmingham is for the purchase of a state-of-the-art light scattering instrument for use in characterizing polymers, polymeric micelles, and dendrimers. This instrument will provide new infrastructure at UAB for research and education in the area of polymeric materials. From a research perspective, this instrument will be extremely valuable in characterizing masses and sizes of various linear and branched polymers and copolymers and dendrimers being synthesized at UAB. It also will provide a powerful means for characterizing polymer micelles, a research area of intense current interest in the Department of Chemistry. Overall, new and existing research programs of about thirty research scientists in the UAB Chemistry Department will be favorably impacted. In addition, this instrument will allow new teaching laboratories for both Biochemistry and Polymer Chemistry classes, thus exposing approximately forty students annually to the use of light scattering for characterizing natural and synthetic macromolecules.%%%
