Professor Xiaokong Liu's team at Jilin University proposed an "activation-quenching" strategy for dynamic covalent chemistry, achieving precise and controllable "on-off" switching of dynamic bond exchange reactions in dynamic covalent polymers (covalent adaptive networks or CANs). This strategy enables the polymer network to reversibly switch between a remodelable dynamic state and a highly stable thermosetting state on demand, effectively balancing the material's remodeling processability and thermal stability, and providing a novel approach to resolving the contradiction between sustainability and stability in dynamic covalent polymers.  The article was published as an open access research article in CCS Chemistry, the flagship journal of the Chinese Chemical Society. 

Researchers in China have discovered an innovative way to improve the stability and efficiency of biogas production by using carbon materials made from lignin, a major byproduct of the paper industry. The study, published in Carbon Research, demonstrates that two lignin-derived materials, lignin hydrochar (LHC) and carbon quantum dots (CQDs), can effectively reduce ammonia inhibition, a long-standing challenge in anaerobic digestion systems.

As the planet warms and rainfall patterns shift, new research suggests that the world’s largest grassland region may become a growing source of nitrous oxide, a greenhouse gas nearly 300 times more potent than carbon dioxide.

When compost piles reach nearly boiling temperatures, most life would perish—but not the resilient microbes thriving within.

An AI from the University of Würzburg autonomously controlled a satellite in orbit for the first time, demonstrating the potential of intelligent, self-learning space systems.
