Synthesis of Coal Tar‐Based Hypercrosslinked Polymers via Friedel‐Crafts Alkylation: An Efficient Way to Access Carbon Electrode Material for Supercapacitors

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Liquid coal tar (CT) is synthesized into hypercrosslinked polymers (HCPs) via the Friedel–Crafts alkylation, followed by oxidation‐carbonization to form disordered microporous carbon. The resulting CF2CT exhibits a high three‐electrode specific capacitance of 342 F g−1 at 1 A g−1, and the assembled symmetric supercapacitor illuminates a light sign ...

Sustained and Enhanced Nucleate Boiling Using Hierarchical Architectures at Large Superheats

open access: yesExploration, EarlyView.
Sustained nucleate boiling and Leidenfrost delay are critical for thermal and energy industries. Leveraging vapor buffer and reducing water‐hammer pressure, this study realizes the enhancement of nucleate boiling and postponement of Leidenfrost by rationally designing and developing hierarchical nano–micro structured surfaces. Besides, AI technology is
