Researchers from the Shanghai Advanced Research Institute and collaborating institutions have achieved high-precision measurements of the 27Al(γ,n)26Al photoneutron cross section using quasi-monochromatic γbeams at the Shanghai Laser-Electron Gamma Source (SLEGS). By employing a novel flat-efficiency neutron detector array, the team reduced measurement uncertainties to below 4%, resolving discrepancies in existing experimental data and improving theoretical models for nuclear astrophysics. The results, spanning 13.2–21.7 MeV, provide critical insights into the production of 26Al in cosmic environments and address inconsistencies with prior datasets.
High-performance neodymium-iron-boron (Nd-Fe-B) magnets are susceptible to environmental degradation. In a recent breakthrough, researchers from Hangzhou Dianzi University in China have pioneered a novel coating technology to overcome their long-standing vulnerability in harsh conditions. This work is expected to pave the way for the reliable use of Nd-Fe-B magnets in offshore wind turbines, aerospace systems, as well as other extreme environments.
