Topological semimetals are one of the major discoveries in condensed-matter physics in recent years. The magnetic Weyl semimetal, in which the Weyl nodes can be generated and modulated by magnetization, provides an ideal platform for the investigation of the magnetic field-tunable link between Weyl physics and magnetism.
The Experimental Advanced Superconducting Tokamak (EAST) had its 100,000th discharge on 8 June, marking another memorable moment in its fifteen-year history since its first operation in 2006. This is just ten days after setting new world record at the end of May when they set a record for sustained heat in nuclear plasma－a temperature of 120 million C for 101 seconds.
Recently, a research team led by Prof. ZHAO Bangchuan from the institute of Solid Materials, Hefei institutes of Physical Science (HFIPS) developed a new anode material (NiCo2N) for lithium-ion batteries (LIBs). This material, which can be obtained via a simple synthesis process, exhibits superior cycling stability with large reversible specific capacity and high-rate performance.
Creating an efficient fusion plasma in a tokamak requires balancing competing temperature needs of the plasma – extremely hot in the core to allow fusion to occur but cool enough at the edge not to damage the walls of the device. Recently, China’s Experimental Superconducting Tokamaks (EAST) team from Institute of Plasma Physics (ASIPP), Hefei Institute of Physical Science (HFIPS), together with their international collaborator from DIII-D National Fusion Facility, developed an innovative solution to this challenge that uses active injection of gases to cool the plasma in the edge region of an advanced tokamak plasma, reducing the heat before it reaches the walls of the tokamak. Even better, they have done this while maintaining high plasma performance in the core region.
A roving photo exhibition organized by division of international collaboration, HFIPS was telling the stories of international cooperation of science islanders in the past decades.
