Recently, a research team led by Prof. HUANG Liansheng from Institute of Plasma Physics (ASIPP), Hefei Institutes of Physical Science (HFIPS) of Chinese Academy of Sciences, developed a new generation of poloidal field coil power supply (rated current ± 15kA).
Low-power FRS nitrogen dioxide sensor basing on ring array permanent was proposed by a research team led by Prof. GAO Xiaoming from Hefei Institutes of Physical Science of Chinese Academy of Sciences, according to a paper published in Analytical Chemistry. Gaseous medium immersed in an external longitudinal magnetic field leads to changes in the polarization state of the linearly polarized light. Faraday rotation spectroscopy (FRS) can detect paramagnetic molecules by sensing the changes.
According to a research published in Advanced Science recently, scientists successfully improved the specific capacity of Na3V2(PO4)3, a new electrode material. They also found its relatively exotic extrinsic pseudocapacitance behavior.
Recently, the research team led by prof. Kong Lingtao from Institute of Solid State Research, Hefei Research Institute of Chinese Academy of Sciences (CAS) proposed a pre-assembly strategy to anchor single atoms on carbon nitride nanosheets. They prepared a series of single atom-loaded carbon nitride Fenton-like catalysts for the degradation of tetracycline pollutants in water, which increased the catalytic activity by 1-2 orders of magnitude.
In recent years, lithium ion batteries have been widely used in many fields. Compared with traditional lithium ion battery cathode materials, more lithium ions in lithium rich manganese based cathode materials of unit mass participate in energy storage. However, in the process of battery reaction, stress accumulation and lattice oxygen loss will cause some microcracks in lithium rich manganese based materials. The migration of transition metal ions will lead to phase transition of materials and other harmful side reactions, making the actual battery performance less than ideal.
