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

衍射硬件、理论和软件以及计算机的最新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。这也使他们越来越容易接近新手，如本科生。在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，包括：生物化学，生物学，化学，地质学，物理学，材料科学，工程和科学教师教育。将衍射更广泛地整合到本科课程中的最大障碍之一是缺乏适当的衍射仪。该项目正在调整和实施区域主要本科院校（PUI）和研究仪器网络的几种现有合作模式。一个WEB访问衍射设施，强调单晶方法，但与一些粉末的能力已经建立在这个instituion。它致力于本科教学的正式课程和本科研究。该设施完全可以通过WEB访问，以便参与PUI的教师和学生能够远程观察和控制衍射仪器，并访问位于该机构的数据库。结构解决方案软件，用于在每个家庭网站提供的是教师培训和课程实施的帮助，为22个参与PUI。由于操作在一个远程模型提出的仪器访问，这个设施是特别有用的教师和学生在地理上偏远地区，那些从资金不足的机构，或那些残疾人的旅行造成问题。

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.
