Scientists created dye-based molecules that self-assemble into ring-shaped structures, mimicking nature’s light-harvesting systems. These stacked rings allow electrons and energy to circulate freely, demonstrating a phenomenon called toroidal conjugation. The work could inspire new materials for solar energy, optoelectronics and next-generation electronic devices.

The formation of humins during lignocellulosic biomass refining is a key factor causing low efficiency and separation challenges. This study systematically analyzes the mechanism and influencing factors of humins formation, proposes targeted inhibition strategies and value-added utilization pathways, offering important guidance for the development of humins chemistry.

In a study published in National Science Review, a research team led by Professor YAO Huajian from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) revealed the significant impact of tidal forces on the changes in seismic wave speeds in the fault fracture zone by monitoring the temporal changes in seismic wave speeds.

A research team led by Prof. KANG Yanbiao from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS) has developed a supercapacitor (SC)-assisted electrophotocatalysis for the efficient defluorination of the polytetrafluoroethylene (PTFE) and poly- and perfluoroalkyl substances (PFASs) at low temperatures. They incorporated the strength of both electrochemical and photochemical energy, providing more possibilities for solving environmental problems caused by PTFE and PFASs. The study was published in Angewandte Chemie International Edition.

With the rapid development of the space industry, enhancing the stealth and survivability of spacecraft has become a critical challenge. Professor Qiang Li’s team at Zhejiang University has developed an innovative multilayer thin-film camouflage device, enabling invisibility across H, K, MWIR, and LWIR bands while efficiently radiating heat to address thermal control issues in space. This technology achieves precise management of solar and thermal radiation, offering significant support for future space exploration.
