Academician Yu-Zhong Wang's team at Sichuan University proposed an innovative "LEGO" strategy, successfully upgrading and recycling waste polyethylene (PE) into high-performance materials with multiple functions. This strategy degrades PE into oligomers, which are then modularly assembled with different functional monomers through dynamic imine bonds. This allows for customized functionalization, achieving multiple functions such as flame retardancy, antistatic properties, UV shielding, and dyeability. Simultaneously, the resulting material exhibits good physical and chemical recyclability. The article was published as an open access Research Article in CCS Chemistry, the flagship journal of the Chinese Chemical Society.

Removing part or all of the breast during breast cancer treatment is a potential outcome for some people. Reconstructive surgical procedures often involve prosthetic implants or transplanted tissue from elsewhere in the body. So, researchers reporting in ACS Applied Bio Materials developed a prototype injectable paste derived from human skin cells that could help restore breast volume after tumor removal, with less scarring and shorter healing time than current options.

Chinese researchers have successfully developed and mass-produced a next-generation superconducting magnet jacket, designated CHSN01, marking a significant stride in China's pursuit of clean fusion energy. This homegrown advanced material far surpasses current international standards in key performance metrics, positioning China at the forefront of cryogenic structural material technology for future fusion reactors.

A newly designed robust mechanophore provides early warning against mechanical failure while resisting heat and UV, report researchers from Institute of Science Tokyo. They combined computational chemistry techniques with thermal and photochemical testing to show that their mechanophore scaffold, called DAANAC, stays inert under environmental stress yet emits a clear yellow signal when mechanically activated. This could pave the way for smart, self-reporting materials in construction, transportation, and electronics.

Researchers from the Fritz Haber Institute of the Max Planck Society have unveiled fundamental new insights into the working principles of fuel-cell catalysts. Their study, published in Nature Communications, reveals how multiple steps during the conversion of oxygen (O₂) to water (H₂O) give rise to the overall catalyst kinetics, and how this is related to changes at the catalyst-solution interface. The study constitutes a profound step forward in our understanding of multi-step electrocatalytic reactions.

Through theoretical derivation, researchers have concluded that a simple linear relationship exists between the reactivity of molten salt reactors and the reciprocal of uranium concentration in the fuel salt. This relationship has been validated through numerical simulations, demonstrating its general applicability, which is expected to have a far-reaching impact on the theoretical development of reactor physics.
