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.

If you want to learn about China, you won’t miss the Spring Festival that is indisputably considered by all the Chinese people the most important traditional festival around the year to celebrate the coming of Chinese New Year.
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.
A huge plume of ash, steam and gas rising up high from the underwater near Tonga has captured attention around the world on January 14 just two weeks later from the beginning of 2022. The communication to the outer world has been cut off immediately after the volcano eruption, the devastating explosion was still captured by the satellite orbiting the earth. The explosion may not be the one impacting the planet the most, “but to witness it with the modern array of instruments we have is truly unprecedented”, just as Lori Dengler said, an emeritus professor of geophysics at Humboldt State University in California.
