We explore in science to push boundary of human knowledge by uncovering mysteries in matter, figuring out why behind phenomenon, finding innovative way to go deep and far.
As looking back at the year of 2022, we organize here those brilliant work published in well-known journals shines like stars above but also pictures what HFIPSers do and how they explore in science.
MENG Guowen with Institute of Solid State Physics and their collaborators developed a structurally integrated, highly-oriented carbon tube grids as electrodes of electric double-layer capacitors, to significantly improve the frequency response performance and the areal and volumetric capacitances at the corresponding frequency. It is expected to be used as a high-performance small-sized alternating current line-filtering capacitor in electronic circuits, providing the essential materials and technology for the miniaturization and portability of electronic products.

In-house researchers with Institute of Plasma Physics and their collaborators prove experimentally, for the first time, the current driven by turbulence, via observed data during the experiment and simulations after. The turbulence-driven current, according to the team, was also an important factor to sustain the 100 million degrees of electron temperature stationary long-pulse plasma on EAST.
