    Scientists from the National University of Singapore (NUS) have developed a highly effective and general molecular design that enables an enhancement in radioluminescence within organometallic scintillators by more than three orders of magnitude. This enhancement harnesses X-ray-induced triplet exciton recycling within lanthanide metal complexes. Detection of ionizing radiation is crucial in diverse fields, such as medical radiography, environmental monitoring and astronomy. As a result, significant efforts have been dedicated to the development of luminescent materials that respond to X-rays. However, current high-performance scintillators are almost exclusively limited to ceramic and perovskite materials, which face issues such as complex manufacturing processes,...

    Harnessing these molecules can significantly impact agriculture, pharmaceuticals, and electronics. Chemists at the University of Minnesota Twin Cities College of Science and Engineering have successfully synthesized a highly reactive chemical compound that has eluded sicentists for over 120 years. This breakthrough may pave the way for the development of innovative drug treatments, safer agricultural products, and enhanced electronics. For decades, researchers have been investigating molecules called N-heteroarenes, which are ring-shaped chemical compounds that contain one or more nitrogen atoms. Bio-active molecules having a N-heteroarene core are widely used for numerous medicinal applications, lifesaving pharmaceuticals, pesticides and herbicides, and even electronics....
