Past Projects

• Structure Analysis.
  The primary role of the laboratory is the determination of molecular structures. The IUMSC has a capability of examining over 400 crystals per year. In addition to the instruments available in the laboratory, we have active collaborations which provide access to synchrotron sources as well as neutron data. The laboratory currently has a SMART6000 CCD instrument (from Bruker-AXS), an R-Axis imaging plate system with a rotation anode source (from Molecular Structure Corporation), a Scintag powder diffraction system, and six Picker four-circle instruments. The laboratory also has an excellent assortment of support equipment including microscopes and other tools essential to the study of crystals.
  
• Remote Access to Instrumentation.
  A major effort is underway to develop the hardware and software to provide researchers access to remote instrumentation. Such systems provide nearly continuous monitoring capabilities for work in progress in the laboratory, and are being developed primarily to allow remotes access to synchrotron and neutron sources at remote sites. Check out the SCrAPS, MBCAT, and XPort links on the www.iumsc.indiana.edu home page for details on these projects. The remote links to the IUMSC are available through the home page.
  
• The Reciprocal Net-A Distributed Molecular Database.
  The Reciprocal Net is a major project directed by the IUMSC and funded by the NSF. As a collection project of the National Science Digital Library the project will provide not only a significant teaching resource for K-12, but will also provide a global network of molecular databases. Details are available from the IUMSC home page or through http://www.recipnet.org.
  
• Analysis and Visualization of Instrument Driven Data (AVIDD).
  To aid in the analysis of crystallographic data the IUMSC is a significant participant in the AVIDD project at Indiana University. The system will be used for storage and preliminary analysis of CCD data from the local instruments as well as from the instruments located at the National Laboratories. With access to Internet2, several hundred processors, and several terrabytes of rotating storage, the system allows unprecedented analysis capabilities for the crystallographer. Details are available at http://www.indiana.edu/~uits/rac/avidd/ and http://www.indiana.edu/~uits/rac/avidd/demo.html.
  
• Molecular Visualization
  In conjunction with the Advanced Visualization Laboratory and the School of Informatics, the IUMSC is developing a series of scalable graphics programs that can be used for the visualization of molecules. The software can be deployed on Windows based systems and can be scaled to work in the CAVE environment available to researchers at IU Bloomington. High quality graphics are generated using a dedicated BeoWulf system located in the IUMSC (see http://www.iumsc.indiana.edu/SC2000.htm).
