A research team led by Prof. XIONG Wei from Hefei Institutes of Physical Science (HFIPS), Chinese Academy of Sciences (CAS), monitored and analyzed the greenhouse gas concentrations before and after Tonga eruption with the Greenhouse Gases Monitoring Instrument (GMI).
With good properties, heavy/high-Z metal material has been considered as the first choice for plasma facing components in International Thermonuclear Experimental Reactor (ITER). However, at thermonuclear fusion relevant temperatures, the accumulation of heavy/high-Z particles (impurities) in the core region may significantly cool the plasmas, deteriorating the plasma performance and leading to H to L-mode back transition and even further to radiative collapse. Therefore, it is important to know more about the core heavy impurities transport so as to control their central accumulation for the stable operation of Tokamak fusion devices.
When the Chinese Lunar New Year of Tiger is approaching, alongside is the Beijing Winter Olympic 2022, making Beijing the world’s first "Dual Olympic City".
The traditional refrigerant represented by Freon is a strong greenhouse gas that leads to serious climate problems. Stimulated by the excellent cooling performance of plastic crystal materials, barocaloric (BC) cooling received much attention recently as a promising green refrigeration technology. However, problems like high driving pressure and low thermal response remain unsolved, which hindered their practical applications.
Recently, the team from the Institute of Solid State Physics, Chinese Academy of Sciences obtained a catalyst composed of the hollow carbon sphere and inner Ni nanoparticles (Ni@HCS), which displayed good performance when applied in the aqueous phase hydrogenation rearrangement tandem reaction of furfural (FAL), a typical aqueous phase reaction.
