Oxygenation strategies provide an easy route to long wave infrared layered crystals
Large crystal and transmission spectra of rb2sb2ocl6 in sb3+ of rb13Sb8cl37, rb3sb2ocl7, and rb2sb2ocl6, sb3+ of rb13sb8cl37, rb3sb8cl37. Credit: Dr. Li Xinyang Long-wave infrared layered crystals are essential materials for infrared optical applications in fields such as infrared imaging, laser technology, and optical communications. High-performance long-wave infrared layered crystals have rarely been reported due to birefringence, infrared transmission and limitations…

Megastudy finds easy ways to increase math progress
Credit: Pexel American students have lagged behind mathematics for decades, with a consistently ranked test score of 25% worldwide compared to students in other developed countries, and the situation has been exacerbated by the Covid-19 pandemic. Previous research has shown that behavioral science-based interventions targeting student motivations are effective in increasing mathematical scores, suggesting that taking a similar “behaviorally informed”…

Chemists discover easy way to make biodiesel from waste oil
Graphical summary. Credit: Energy and Fuels (2024). DOI: 10.1021/acs.energyfuels.4c03643 Chemists at the University of California, Santa Cruz have discovered a new way to make biodiesel from waste oil that simplifies the process and requires relatively mild heat. The discovery has the potential to make alternative fuel sources more attractive to the large industrial sector that is the backbone of the…

Nuclear rockets may reach Mars in half the time, but designing the reactors to power them is not easy
Nuclear-powered rockets may one day enable faster space travel. Credit: NASA NASA plans to send a crewed mission to Mars over the next decade, but the 140 million mile (225 million kilometer) journey there could take months or years round trip. This relatively long flight time is a result of the use of conventional chemical rocket fuel. The agency is…
