WEB Accessible Single Crystal X-Ray Diffractometer for Undergraduate Instruction at a Consortium of Predominantly Undergraduate Institutions

化学(12)最近在衍射硬件、理论和软件以及计算机方面的改进使衍射方法越来越成为许多学科的科学家、工程师和专业人员的常规方法。这也让它们越来越容易被本科生等新手接触到。各种机构的经验表明，这些方法可以有效地整合到各种学科的本科课程中，包括：生物化学、生物、化学、地质学、物理、材料科学、工程学和科学师范教育。将衍射学更广泛地融入本科课程的最大障碍之一是缺乏接触到合适的衍射仪的实际机会。该项目正在调整和实施几个现有的协作模式，这些模式来自以地区为主的本科院校(PUI)和研究仪器网络。在该研究所建立了一个网络可访问的衍射设备，强调单晶法，但具有一定的粉末能力。它致力于正规课程和本科研究的本科生教学。该设施完全可以通过网络访问，因此参加PUI的教职员工和他们的学生能够远程观察和控制衍射仪器，以及访问位于该机构的数据库。提供了在每个家庭站点使用的结构解决方案软件，以及为22个参与的PUI提供的教师培训和课程实施帮助。由于建议的仪器访问远距离操作模式，该设施对地理偏远地区的教职员工和学生、资金较少的机构的教职员工和学生，或那些残疾导致旅行困难的人特别有用。

Chemistry (12) Recent improvements in diffraction hardware, theory, and software, and in computers have made diffraction methods increasingly routine for scientists, engineers, and professionals in many disciplines. It has also made them increasingly accessible to novices such as undergraduates. Experience at a variety of institutions has shown that these methods can be effectively integrated into the undergraduate curriculum in a wide variety of disciplines, including: biochemistry, biology, chemistry, geology, physics, materials science, engineering, and science teacher education. One of the biggest impediments to integrating diffraction more widely into undergraduate coursework is the lack of hands on access to appropriate diffractometers. This project is adapting and implementing several existing collaborative models from regional Predominantly Undergraduate Institutions (PUIs), and research instrumentation networks. A WEB-accessible diffraction facility that emphasizes single crystal methods but with some powder capabilities has been established at this instituion. It is dedicated to undergraduate instruction in both formal courses and undergraduate research. The facility is fully accessible over the WEB so that participating PUI faculty and their students are able to both observe and control the diffraction instruments remotely as well as access databases located at the institution. Structure solution software for use at each home site is provided as are faculty training and curriculum implementation help for the twenty two participating PUIs. Because of the operation over a distance model proposed for instrument access, this facility is particularly useful to faculty and students in geographically remote regions, to those from less well funded institutions, or to those whose disabilities make travel problematic.
