Recently, scientists from Shanghai Institute of Optics and Fine Mechanics and the Department of Physics and Astronomy, University of New Mexico, had cooperatively proposed a "reflectivity and laser-resistance in one" design by using tunable nanolaminate layers with co-evaporated interfaces (NLD coating).
A research group led by Prof. GUO Guangcan, LI Chuanfeng, and XIANG Guoyong from University of Science and Technology of China (USTC) of the Chinese Academy of Sciences enhanced the performance of quantum orienteering with entangling measurements via photonic quantum walks.
A little over a year after landing, China's spacecraft Chang'E-4 is continuing to unveil secrets from the far side of the Moon. The latest study led by scientists from the National Astronomical Observatories of the Chinese Academy of Sciences reveals what lurks below the surface.
A research team led by Prof. LU Xiaochun from the National Time Service Center analyzed the origin of Beidou Navigation Satellite System (BDS) pseudorange biases for the first time, and proposed several effective methods for mitigating the biases.
Researchers from the Institute of Mechanics, teaming up with scientists from Singapore and the U.S., have found that nanoscale precipitates provide a unique sustainable dislocation source at sufficiently high stress. They discovered that densely dispersed nanoprecipitates simultaneously serve as dislocation sources and obstacles, leading to a sustainable and self-hardening deformation mechanism that enhances ductility and strength.
The research team led by Shanghai Institute of Optics and Fine Mechanics, together with East China Normal University and Nanjing University of Aeronautics and Astronautics, has recently demonstrated single-mode lasing with low threshold, highly linear polarization degree and good stability at ~531 nm by Vernier effect in coupled perovskite microspheres.
