RTNN’s Dr. David Berube to serve on FDA’s Risk Communication Advisory Committee

Posted on by

We are excited to announce that RTNN’s Dr. David Berube will serve as a member on the Risk Communication Advisory Committee for the Food and Drug Administration (FDA) beginning this October and spanning into the next administration. As a committee member, Dr. Berube will advise the FDA Commissioner on strategies to effectively communicate the risks and benefits of FDA-regulated products to the public. The committee is also tasked with reviewing and evaluating relevant research and facilitating the implementation of public communication programs.

New Approach to Determine Atomic Arrangement in Materials

Posted on by

RTNN researchers at NC State University have published an article describing a new way to determine how atoms are arranged in materials. The work, “Use of Bayesian Inference in Crystallographic Structure Refinement via Full Diffraction Profile Analysis” published in Scientific Reports describes the application of Bayesian statistical methods to X-ray diffraction patterns. This method allows researchers to characterize and better estimate the variability in a material’s atomic structure. The technique is under development for use with spectra collected from other analytical tools like X-ray photoelectron spectroscopy. This tool-set will inform the development of materials for a variety of novel applications.

A press release describing the work can be found here. The article in its entirety can be found here.

RTNN congratulates Houston Dycus, Dr. Jim LeBeau, and Matt Cabral for their recent awards at the 2016 Microscopy & Microanalysis meeting. Dycus (left picture), LeBeau, and Cabral (right picture) are all in the Department of Materials Science and Engineering at NC State. Dycus and LeBeau were awarded the best paper in the Microscopy and Microanalysis Journal (Materials Science Category) for their paper: “Accurate nanoscale crystallography in real-space using scanning transmission electron microscopy.” Dycus also received the best poster award for his work, “Resolving Atomic Scale Chemistry and Structure at NO and Ba Passivated SiC/SiO2 Interfaces.” Cabral won a Student Scholar award for his contribution entitled: “Direct Observation 
of Local Chemistry and Local Cation Displacements in the Relaxor Ferroelectric PMN-PT.”

Upcoming seminar: “Materials Science in Caribbean Art and Archaeology”

Posted on by

We are excited to announce an upcoming seminar by Professor Antonio Martínez-Collazo. Professor Martínez will discuss his work using materials characterization techniques to study works of art and archaeological artifacts. Following the talk, the Analytical Instrumentation Facility (AIF) at NC State will host tours for interested attendees to learn more about available characterization techniques and instrumentation.

RTNN to host a microfluidics workshop

Posted on by

RTNN is excited to announce an upcoming microfluidic workshop at the Chapel Hill Analytical and Nanofabrication Laboratory (CHANL). This workshop will offer participants the opportunity to learn about patterning structures across different length scales (nm→μm) and become familiar with a number of important application areas – microfluidics and nanofluidics for biological/biomedical applications. There will be lectures covering relevant technological and application areas with on-site visits and demonstrations of relevant equipment. The last day of the workshop will involve a hands-on experience; making a microfluidic device. More details can be found here and on the CHANL website.
