Looking inside 18th Century Ivory Mannequins

Duke’s Shared Materials Instrumentation Facility (SMIF) is working with conservationists at Rubenstein Library to carefully image anatomical models that have been housed behind glass since the 1950s. Once the original has been scanned, researchers use a 3D printer to create a plastic replica. The model can be handled to prevent damage to the original.

Non-ambient X-ray Diffraction Symposium

Non-ambient X-ray diffraction is a useful tool for determining phase stability, studying phase transformations, and following reaction pathways and kinetics. Practical examples include in-situ battery analysis for developing new cathode materials, understanding pharmaceutical stability with temperature and humidity, quantifying growth kinetics of nanocrystalline systems, and many more. New non-ambient chambers, faster instruments, and automatic data processing make non-ambient diffraction an ever-increasingly powerful technique. However, there are issues that can trip up the unwary, such as thermal gradients, unwanted reactions, systematic errors, etc. This symposium will feature lectures by leading researchers developing and using non-ambient diffraction on laboratory instruments, synchrotrons, and neutron beamlines. Lectures will focus on the research potential of non-ambient diffraction and practical advice for collecting accurate and useful data.

Attendees are encouraged to present a poster on their work related to this symposium. Speakers will judge the posters and prizes will be awarded to the top 3.

X-ray Diffraction Short Course

NC State’s Analytical Instrumentation Facility (AIF) is giving a hands-on short course on X-ray Diffraction (XRD). This introductory course will cover basic principles of X-ray diffraction, operation of diffractometers in Bragg-Brentano geometry (that typically used for powders), and basic phase identification. It is meant for first-time XRD users and/or those interested in learning phase identification and pattern matching in HighScore software. The course will include a 1-hour theory component, 1-hour of phase identification training in the AIF Data Analysis center, and 1-3 hours of a practical component in the XRD lab (as needed). After completion of this course and the EH&S course on Analytical X-ray Safety, attendees will be able to independently operate a diffractometer in basic mode.

In order to facilitate authorization to use the equipment, participants are encouraged to take the Analytical X-ray Safety offered by EH&S (see details at here for this information and other requirements to gain future access to the instruments).

For more details and to register, please contact Dr. Ching-Chang Chung at his email cchung4@ncsu.eduCourse limited to 10 people. Registration costs: $50 for academic, government, and non-profit participants; $350 for industry participants.
