Mg₃Sb₂ is a thermoelectric compound composed of cheap and abundant elements. NIMS has successfully improved the thermoelectric performance of Mg₃Sb₂ by doping it with indium and precisely controlling the sintering duration. This approach resulted in substantially increased electronic conductivity while effectively reducing thermal conductivity. The Mg₃Sb₂-based material exhibited a very high figure of merit (zT) of approximately 2.0 at 723 K. In addition, a module made of this material achieved a thermoelectric conversion efficiency of approximately 12.6%—the highest efficiency ever recorded for a single-leg module. These results may greatly advance the development of practical thermoelectric devices.

The combination of low temperature, atmospheric pressure and water vapor pressure on Mars means any liquid water found there would likely freeze, boil or evaporate immediately, making its presence unlikely.  

For the first time, however, the structure of this protective mantle and its interactions with the virus' RNA have been described on an atomic scale by scientists from the CNRS and l’Université Grenoble Alpes – a result that has been awaited by the scientific community for almost forty years. The research team has also revealed the precise positioning of the RNA molecules in their protective coat, and the interactions between the two helix strands.

A strong and impact-resistant plastic that is comparable to steel could be on its way to more efficient processing thanks to new strategies introduced and tested by researchers based in England.

UTSA’s Office of Research today announced the launch of the Center for Space Technology and Operations Research (CSTOR), a new research center dedicated to advancing engineering, technology and operations that will support space missions between the Earth and the Moon, an area referred to as cislunar space, as well as the lunar surface. The center will address the growing demand for research and workforce development by civil, commercial and national security space agencies and companies. David Silva, UTSA distinguished professor of physics and astronomy, will serve as the center’s inaugural director.

CSTOR will provide enhanced support to the more than 35 UTSA researchers and over 200 students working on space technology related research and career development in areas such as uncrewed spacecraft, lunar habitation, hypersonics and propulsion. It will further augment the university’s effort to attract even more of the nation’s brightest minds in space technology through UTSA's clustered and connected faculty hiring plan, supported by the UT System Board of Regents’ Research Excellence Program.

“UTSA has intentionally expanded its capacity, facilities and expertise in space technology to meet the rapidly growing demand for innovation and enable stronger comprehensive partnerships with key organizations like Southwest Research Institute and Department of Energy National Labs,” said UTSA President Taylor Eighmy. “The launch of this new center positions UTSA as a destination for innovation, knowledge creation and talent development for the space economy.”
