On March 29, 2023, Advanced Materials reported that Yan Jianfeng and his team at Tsinghua University assembled metal nanocrystals (gold nanoparticles) into an interconnected network based on a laser-plasma fabrication strategy using glue molecules. They found that the nanogaps triggered by the cement molecules between nanocrystals can be controlled by molecular modulation to form locally oscillating electrons. Through the decomposition of glue molecules and the excitation of multi-plasma modes, the optical absorption of the bridge receptive rice crystal is enhanced, so that the optical thermal conversion ability is stronger. The optical response information encryption and soft actuator constructed by this method have good photothermal stability. This work provides a promising strategy for creating a wide range of functional plasma nanocrystals through laser material interactions at the nanoscale.

The main object studied in this work is gold nanoparticles from XFNANO.

On April 9, 2023, Advanced Energy Materials reported on the solid-phase conversion of lithium-sulfur batteries by Ke Fusheng and Chen Shengli's team at Wuhan University. In this work, an electrode/electrolyte interface membrane with high stability, high ionic conductivity and self-repair function was constructed in situ through the interaction between a solvent with low Donor Number (DN) and lithium salts and lithium polysulfide, which prevented the subsequent dissolution of lithium polysulfide. The shuttle problem of multi - lithium sulfide in lithium - sulfur battery is solved fundamentally. This study fully demonstrates that the electrochemical performance of high specific capacity electrode materials can be significantly improved by adjusting the composition and structure of electrolyte and interface, and provides a new idea for the development of high safety and high energy density battery systems.

Article chose two kinds of porous carbon (CMK-3 and MCF-C) as the carrier of sulfur, CMK-3 are from XFNANO.
