Liquid Metal–Polyphenol Hybrids for Solar Steam Generation
Advanced Science, EarlyView.The combination of liquid gallium nanoparticles, graphene, and a metal‐phenolic gel creates a unique architecture that can act as a highly efficient broad–spectrum solar light absorber. The resulting composite applied for solar steam generation can produce clean water with an evaporation rate of 3.4 kg m−2 h−1 under 1 Sun illumination from seawater ...

Advanced Science, EarlyView.This study utilizes surface chemistry engineering to enhance coal‐based carbon materials for sodium storage. By introducing oxygen‐containing functional groups (OFGs) via pre‐oxidation, the researchers found that carboxyl groups delay decarboxylation during pyrolysis, enabling extended intermolecular rearrangement up to 600 °C while suppressing soft ...

Advanced Science, EarlyView.A sustainable high‐performance epoxy vitrimer (F9T1) was developed via a rigid‐flexible integrated design using rigid and flexible bio‐based epoxy monomers. F9T1 features superior mechanical property, char‐forming ability, fire safety, chemical degradability and recyclability due to its rigid‐flexible network with abundant dynamic disulfide and ester ...
