Professors receive $1M to study fundamental bonding in metallic alloys

Principal investigator Dr. Srinivasan Srivilliputhur and co-PI Dr. Rajarshi Banerjee in lab

A UNT Engineering research team is working to better understand how metal alloys function at the atomic level with a $1 million grant from the Department of Defense, under the U.S. Air Force Office of Scientific Research.

The team consists of three experts from the Department of Materials Science and Engineering: Principal investigator professor Srinivasan Srivilliputhur and co-PIs Rajarshi Banerjee, a Presidential and Regents Professor and University Distinguished Research Professor Michael Baskes, a member of the U.S. National Academy of Engineering.

The UNT team will create a model using physical experimentation and advanced computer simulations that will allow scientists to understand exactly what properties and tolerances will result from mixing different kinds of atoms. They hope to develop a generalized model useful to predict strengths of alloys. Learn more.

Researcher to change protective surface of mechanical systems

UNT faculty Diana Berman

Materials science and engineering Assistant Professor Diana Berman has received a $290,000 National Science Foundation grant to help mechanical systems, like combustion engines and turbines, last longer and go farther by changing how their protective surface coatings are designed.

Currently, coatings are deposited into a mechanical system where they will eventually wear and tear down due to interaction with water, fuel or other hydrocarbons. Once this happens, the system will need to be completely disassembled so the coatings could once again be deposited into the system. Berman’s approach will allow the damaged surfaces to be repaired without having to disassemble the entire mechanical system, saving time, energy and resources. Learn more.

NSF grant to help with private information retrieval

Hua Sun

Imagine a world in which you could privately send and receive information on the web without anyone tracking that data. That’s what Hua Sun, an assistant professor in the Department of Electrical Engineering, is trying to do.

Sun’s research focuses on private information retrieval, and thanks to a new $218,259 National Science Foundation grant, he will be able to dive deeper into the fundamentals of understanding what is and isn’t possible in the field. Learn more.

DIY 3D printed mask and nose plugs

Yijie Jiang and student working in the lab

A researcher and his students have developed open source codes for a new mask and nose plug that uses smart technology to respond to a wearer’s breathing. And the best part? Anyone with a 3D printer at home could make their own.

It’s a project the team started in early May as an effort to help the general public combat the COVID-19 epidemic. The masks and nose plugs are designed with an array of channels that include curved micropillars in each channel that move inward or outward as a person breathes. Learn more.
