Neptunium is the main radioactive component of nuclear waste, with a complex atomic structure that can be explored through mass spectrometry. This analysis is crucial for understanding its inherent characteristics and determining the isotopic composition of neptunium waste. Magdalena Kaja and her team from Johannes Gutenberg University in Mainz, Germany have developed a novel laser spectroscopy te...
Recently, a team led by Gao Chunqing and Fu Shiyao from the School of Optoelectronics at Beijing University of Technology combined optical spatial coordinate transformation with photon spin Hall effect to construct a photon angular momentum filter for the first time internationally, achieving on-demand regulation of photon spin angular momentum and orbital angular momentum.The related achievements...
