Prof. JIA Yu from the Institute of High Energy Physics, and his collaborators, unveiled for the first time some deep connections between two fundamental nonperturbative parameters that characterize the intrinsic properties of heavy mesons, which is helpful for predicting heavy meson hard exclusive production processes with better accuracy.
Insight-HXMT, China's first space X-ray astronomical satellite, has discovered a low-frequency quasi-periodic oscillation (QPO) above 200 kiloelectron volts (keV) in a black hole binary, making it the highest energy low-frequency QPO ever found. The scientists also found that the QPO originated from the precession of a relativistic jet (high-speed outward-moving plasma stream) near the event horizon of the black hole. These discoveries have important implications for resolving the long-running debate about the physical origin of low-frequency QPOs.
Recently, scientists of EAST team found that series of Alfven Eigenmodes were excited during the formation of internal transport barrier, i.e. beta-induced Alfven Eigenmodes (BAEs), reversed shear Alfven Eigenmodes (RSAEs) and beta-induced Alfven-Acoustic Eigenmode (BAAE).
Researchers from Shanghai Institute of Technical Physics, University of L'Aquila in Italy and Nanjing University, developed a new kind of photodetector linked to topological. They realized type-II Dirac semimetal-based PDs with room-temperature capabilities of fast response, broadband as well as high signal-to-noise ratio operational in the high-frequency microwave and terahertz band.
A research team from the Shanghai Institute of Optics and Fine Mechanics has recently demonstrated perovskite colloidal quantum dots (CQDs) single-mode laser with good performance across the entire visible spectra range.
Recently, scientists at the Institute of Solid State Physics, Hefei Institutes of Physical Science developed a non-precious alloy catalyst with excellent catalytic activity, selectivity and stability for selective hydrogenation (SH) of cinnamaldehyde (CAL).
