Chemical Instrumentation Facility - is
engaged in a number of ongoing activities, all broadly related to the structure
and properties of molecular crystals. We apply a variety of experimental and
computational techniques to these investigations.
1711 Gilman Hall
Laboratory DescriptionThe X-Diffraction Laboratory is part of the
Chemical Instrumentation Facility of
the Department of Chemistry of
Iowa State University. The facility is
located in room 1709 on the first floor of Gilman Hall on the Iowa State campus.
The X-ray laboratory is both a service and user facility for the university.
Sample compounds may be submitted to the laboratory for data collection and
structure determination by the staff. After supervised training users my collect
data on there own. The X-ray laboratory serves the faculty, staff and students
of the entire University community. The primary users of the laboratory are from
the departments of Chemistry,
Material Sciences and
Chemical Engineering. Available InstrumentationSingle Crystal Diffractometer Bruker-AXS SMART 1000 CCD diffractometer with a charge-coupled-device detector, solid state generator, Mo target tube, and low temperature device. Available for student use or sample submission. The diffractometer is PC controlled (Windows NT) using Bruker AXS SHELXTL software package Powder Diffractometer Scintag XDS-2000, theta-theta goniometer with sealed tube, solid state generator , Cu radiation source and air cooled Kevex Psi Peltier Silicon detector. The bulk of the samples run on the system are powders, but the system can be configured for collection of thin-film data. Instrument is PC controlled (Windows NT) running Scintag DMS software package.Polarization Microscope equipped with Instec hot-stage and digital imaging processing system allow optical study of crystals at different temperatures ( -170C till +350 deg. C)Computing Resources allow authorized users collect and proceed their own data using a variety of networked PC's with different software packages installed. In addition ISU's Project Vincent workstations available through the Department of Chemistry and the Chemical Instrumentation Facility.ServicesThe X-ray laboratory provides the following services:
Cyber-Enabling and Outreach Program The goals of the project are to enhance the current collaborations we have with researchers at other universities, and to offer both educational and research opportunities to all four-year and two-year colleges in Iowa. This project requires the upgrade of the current system to state-of-the-art APEX SMART II CCD detector with APEX software suit. APEX II hardware and software represent a good starting point for designing multi-user cyber-infrastructure. Advanced remote access and control of the Frame Buffer Computer is standard, allowing the remote user to perform all operations associated with testing crystals, determining cell parameters, data acquisition and processing. We have verified with Bruker that their software can be loaded on multiple CPU’s in the lab at no additional cost, as long as each CPU is only used to process data acquired in our lab. There is no specific restriction regarding remote desktop access and use of the software. Even more critical than infrastructure issues to the success of any outreach project (but often overlooked) are the time-intensive personal contacts necessary to establish and develop these relationships. Fortunately, we are well-positioned to overcome that problem. |
