This award from the Instrumentation for Materials research will allow Brandeis University to acquire a light scattering spectrometer that will be the keystone f a facility to perform both static and dynamic light scattering measurements. The facility will be multi-user and multi-disciplinary, as well as fulfill research and educational needs. The facility will consist of an ALV light scattering spectrometer ($80k), a homemade static light scattering spectrometer (built in 1999), and a Brookhaven differential refractometer (purchased in 2000). Currently there are no general-purpose light scattering spectrometers at Brandeis. The equipment will be used as a non-invasive probe to study complex fluids, such as liquid crystals, colloidal suspensions, and protein crystallization in the Physics department. Several members of Biology and Chemistry departments will have access to this facility as secondary users. Their research goals are to study protein complexes. The equipment be used to train physics graduate and undergraduate students and biology graduate students in light scattering, an important technique in its own right, which additionally shares many principles with other techniques such as neutron and x-ray scattering. Students will take either a six or nine week intensive training course in light scattering that will integrate pedagogical instruction with research experience. Instructional exercises will be developed to elucidate both physical phenomena of macromolecules and to provide training in light scattering techniques. This combination will give students a greater understanding of complex fluids in general and will enable them to participate in research, at Brandeis with a deeper understanding of scattering techniques and principles. Finally, this will be the only research-grade general-purpose light scattering instrument at Brandeis University. Thus establishment of this facility will have a large impact on research program of the investigators, as well as serve as a resource for the entire campus.This award from the Instrumentation for Materials research will allow Brandeis University to acquire a light scattering spectrometer that will be the keystone f a facility to perform both static and dynamic light scattering measurements.

来自材料研究仪器的这一奖项将使布兰代斯大学获得一台光散射光谱仪，这将是进行静态和动态光散射测量的设施的基石。该设施将是多用户和多学科的，并满足研究和教育需求。该设施将包括一台ALV光散射光谱仪（8万美元）、一台自制静态光散射光谱仪（1999年建造）和一台布鲁克海文差示折光仪（2000年购买）。目前，Brandeis没有通用的光散射光谱仪。该设备将被用作非侵入式探针，用于研究复杂的流体，如液晶，胶体悬浮液和物理系的蛋白质结晶。生物和化学系的几名成员将作为二级用户使用该设施。他们的研究目标是研究蛋白质复合物。该设备可用于培训物理学研究生和本科生以及生物学研究生的光散射，光散射本身就是一种重要的技术，它还与中子和X射线散射等其他技术共享许多原理。学生将参加为期六周或九周的光散射强化培训课程，将教学指导与研究经验相结合。将开发教学练习，以阐明大分子的物理现象，并提供光散射技术的培训。这种结合将使学生更好地了解复杂的流体一般，并将使他们能够参与研究，在布兰迪斯与散射技术和原理的更深入的理解。最后，这将是布兰代斯大学唯一的研究级通用光散射仪器。因此，该设备的建立将对研究人员的研究计划产生重大影响，并成为整个校园的资源。材料研究仪器的这一奖项将使布兰迪斯大学获得一台光散射光谱仪，这将是进行静态和动态光散射测量的关键设备。该设施将是多用户和多学科的，并满足研究和教育需求。该设备将被用作非侵入性探针，以研究复杂的流体，如液晶，胶体悬浮液，蛋白质结晶和蛋白质复合物。该设备可用于培训物理学研究生和本科生以及生物学研究生的光散射，光散射本身就是一种重要的技术，它还与中子和X射线散射等其他技术共享许多原理。学生将参加为期六周或九周的光散射强化培训课程，将教学指导与研究经验相结合。将开发教学练习，以阐明大分子的物理现象，并提供光散射技术的培训。这种结合将使学生更好地了解复杂的流体一般，并将使他们能够参与研究，在布兰迪斯与散射技术和原理的更深入的理解。最后，这将是布兰代斯大学唯一的研究级通用光散射仪器。因此，该设施的建立将对研究人员的研究计划产生重大影响，并作为整个校园的资源。
