A new type of X-point radiator that prevents tokamaks from overheating

Nuclear fusion reactors are highly powerful technologies that can generate energy by fusing (i.e., joining) two light atomic nuclei to form a heavier nucleus. These fusion reactions release large amounts of energy, which can then be converted into electrical power without emitting greenhouse gases.

One of the most reliable and promising fusion reactor designs is the so-called tokamak. Tokamaks are devices that use a doughnut-shaped magnetic field to confine and heat plasma (i.e., superhot, electrically charged gas) for the time necessary for fusion reactions to take place.

Despite their potential for the generation of large amounts of clean energy, future reactor tokamaks may face huge challenges in managing the intense heat produced by . Specifically, some of the confined plasma can interact with the walls of the reactors, damaging them and adversely impacting both their durability and performance.

Supercapacitor-assisted catalytic system strips fluorine from PTFE and PFAS at low temperatures

A research team led by Prof. Kang Yanbiao from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has developed a supercapacitor (SC)-assisted electrophotocatalysis for the efficient defluorination of the polytetrafluoroethylene (PTFE) and poly- and perfluoroalkyl substances (PFAS) at low temperatures.
