A research group led by Prof. WANG Hui from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences has introduced a metal-free nanozyme based on graphene quantum dots (GQDs) for ...

This diagram illustrates the process of upcycling waste plastics, including various polyesters (PET, PEF, PEA, PES, PLA) and polycarbonates (PC, PPC), using ionic liquid catalysts. The method involves ...

Direct oxidation of methane to methanol is dominated by transition- or noble-metal-based catalysts, thus making the reaction quite expensive. To make the process efficient and cost-effective, ...

Mining metals for lithium-ion batteries carries environmental and ethical concerns. To make batteries more sustainable and to reduce costs, carmakers are trying new strategies, including cutting the ...
