Researchers report an in-situ passivation strategy for pure-blue perovskite light-emitting diodes (PeLEDs), promising for next-generation displays, fabricated by vacuum thermal evaporation. Co-evaporating a phenanthroline ligand (BUPH1) with perovskite precursors coordinates Pb(II) and suppresses halide-vacancy defects, reducing non-radiative losses and spectral drift. Devices emit at 472 nm (FWHM 19 nm) with an EQE of 3.1%—among the highest for thermally evaporated pure-blue PeLEDs—and maintain color stability, compatible with the ITU-R Rec.2020 wide-gamut standard. Next steps target luminance and longer lifetime via additional passivation strategies, toward thermally evaporated device stacks for industrial manufacturing.

SciOpen, a digital publishing platform for scientific, technical, and medical (STM) journals developed by Tsinghua University Press, has recently reached a major milestone: it now hosts more than 200 journals. This achievement not only highlights its strong capacity to attract high-quality journals, but also reflects its growing success in enhancing the global visibility of local journals. SciOpen has also drawn interest from international recognized institutions such as the American Institute of Mathematical Sciences (AIMS) and Tech Science Press.

E-scooters have often been identified as more dangerous than e-bikes, but that picture changes when they are compared on equal terms. A recently published study from Chalmers University of Technology, Sweden, shows in fact that the crash risk is eight times higher for e-bikes than for e-scooters, calculated based on the trip distance with rental vehicles in cities. This surprising result provides a better basis for cities to make decisions on how much to facilitate different types of micromobility.

In 2018 the National Institute of Neurological Disorders and Stroke (NINDS) awarded a five-year, $2.9 million R01 grant to a TTUHSC research team in Amarillo to help uncover and develop much needed therapies for the treatment of ischemic stroke. Due to their high level of productivity and potential to create new medications for stroke injury, NINDS recently awarded a new $3 million competitive renewal that extends the grant for an additional five years to 2030.

The University of Texas at San Antonio launched the College of AI, Cyber and Computing on Sept. 1 bringing together academic programs in artificial intelligence, cybersecurity, computing and data science. The new college positions UT San Antonio at the forefront of technological education and research and brings the number of academic colleges at UT San Antonio to nine.

Earthquake-induced liquefaction of loose, sandy soil can be extensively damaging for built environment. In recent times, chemical grouting of the sand is being used as a method to enhance soil stability and reduce the risk of liquefaction. However, a standardized and effective method to test the resistance is necessary in order to refine the method. In this study, scientists explored the potential of stress-controlled and strain-controlled cyclic triaxial testing.
