A three-year collaboration of scientists from Y‑12 National Security Complex and the University of Tennessee in Knoxville resulted in the innovation of a patented chemical sensor that is unique in several aspects: it’s inexpensive, tiny, and portable; it promises virtually limitless applications; and it allows readings through barriers.

The sensor, named ChIMES (Chemical Identification by Magneto-Elastic Sensing), received one patent last fall, and scientists anticipate approval this spring of a second patent for applications outside national security.

ChIMES is based on chemical recognition materials called molecular recognition phases, or MRPs. Using strategically selected MRPs, sensors can be made that detect chemical and biological warfare agents, toxic industrial chemicals, waterborne and airborne pollutants, explosives, illegal drugs, food pathogens, and exhaled gases that indicate disease or illegal drug use, just to name a few possibilities. In fact, the list of applications for the sensor is virtually unlimited, said Y‑12’s Vincent Lamberti, who managed the project. [Read more…]

In developing countries where white rice is the dominant food, a half million pregnant women and young children become blind and two million die every year because of a Vitamin A deficiency.

On a mission to use genetic engineering to benefit humankind, scientists have genetically modified one type of rice so the grain, not just its leaves, makes Vitamin A. One published study showed that the improved nutritional content of “golden rice” could save sight and lives.

Golden rice was ready to be marketed in 2002, but critics have been calling it a Frankenfood. Golden rice is still not commercially adopted, even though in 2013, Pope Francis personally blessed its use.

This is one of the examples that Tessa Burch-Smith gave in her recent talk as part of the new Roane State Community College–Oak Ridge Institute for Continued Learning Intergenerational Lecture Series. An assistant professor at the University of Tennessee at Knoxville, she teaches and conducts research in UT’s Department of Biochemistry and Cellular and Molecular Biology. [Read more…]

KNOXVILLE—High-entropy alloys—substances constructed with equivalent quantities of five or more metals—might hold the key to future manufacturing and construction, and two researchers from the University of Tennessee in Knoxville could help pave the way.

Doctoral candidate Louis Santodonato, along with his adviser Professor Peter Liaw, both in materials science, did an extensive study into this class of materials, which are considerably lighter and less prone to fracture, corrosion, and oxidation than conventional alloys.

The pair used various methods to observe and model the atomic mixing behavior of high-entropy alloys, work that was picked up by the prestigious journal Nature Communications. [Read more…]
