FeSe is an important prototype material to study the superconducting related properties, and the electron-phonon coupling (EPC) plays an important role in FeSe. Pressure changes the structure of the FeSe, which results in the changes of the EPC.
Volatile organic compounds (VOCs) are important precursors for SOA formation. As a significant aromatic compound of VOC, 1,3,5-trimethylbenzene (1,3,5-TMB, C9H12) has been attracting much attention. It’s mostly emitted from automobile exhaust, solvent use and industry. In the atmosphere, the oxidation reaction of 1,3,5-trimethylbenzene is mainly initiated by OH radicals.
Recently, a research team led by Prof. Jiang Changlong from Institute of Solid State Physics, Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences, developed two nanosensors based on upconversion nanoparticles(UCNPs) to detect semicarbazide(SEM) and heparin, respectively.
Near-infrared spectroscopy (NIRS) is a rapid and non-destructive spectroscopic analytical technique that can play an important role in in the fields of food production and crop breeding. Data fusion technology is a framework containing methods and tools to combine data from different sources, which has received a lot of attention in recent years.
On Dec.26, Long March-4C carrier rocket was successfully launched. Together with it were three sets of metallic damping components for orbit HD optical imaging satellite. They will help to deal with the strong-vibratory shock damage and micro-vibratory interference in the control moment gyro (CMG) of high-definition satellite during rocket launch and in-orbit operation.
