A study by an environmental health expert with the Texas A&M University School of Public Health, along with others at Texas A&M, found that environmental weathering doesn’t just break plastics down; it can actually make them more harmful.

New UNLV-led research is helping to unravel clues to a cosmic mystery that has eluded scientists for decades. Modern astronomical instruments have enabled scientists to understand many of the mechanisms that drive Cataclysmic Variable Systems. But one phenomenon – periodic brightness variations referred to as superhumps – has proven more difficult to explain. In a new paper published March 23 in The Astrophysical Journal Letters, a team of astrophysicists offers a new explanation for the occurrence of negative superhumps in CVs. 

Researchers have designed a nitrogen-rich porous aromatic framework material and investigated its electrochemical performance as the cathode material for sodium organic batteries. The aromatic framework material synthesized by introducing the redox-active hexaazatrinaphthylene (HATN) motif has a high redox potential and multi-ion storage capacity, and can still maintain a high capacity and excellent stability within the temperature range of -20 °C to 50 °C.

Junge Zhang et al., at Jiangsu University, China, provide a comprehensive review published by Frontiers of Materials Science on the challenges and opportunities in the field of hydrogenation catalysis. Despite its fundamental importance in producing everything from pharmaceuticals to fuels, current hydrogenation methods often fall short, struggling with efficiency, selectivity, and durability, leading to higher costs, more waste, and environmental concerns. Researchers are constantly seeking ways to make these reactions greener, more precise, and more sustainable.
