This review examines bio‐based polyurethanes from renewable feedstocks, focusing on structure‐property relationships governing mechanical performance. It analyzes reinforcement strategies, benchmarks against petrochemical counterparts, and explores future directions, including non‐isocyanate routes and circular economy integration for sustainable high ...

The graphical abstract illustrates a circular waste to value pathway in which coal fly ash is upgraded by isolating unburned carbon and converting it into functional carbon materials. Through carbonization and activation, UC‐derived carbon is transformed into high surface area electrodes for supercapacitors, supporting sustainable energy storage and ...

Hydrogen‐powered aviation offers a transformative pathway to zero‐emission flight by eliminating in‐flight CO2 emissions. Key considerations include propulsion systems (fuel cells and hydrogen combustion), cryogenic storage and insulation challenges, infrastructure and cost barriers, and supply‐chain constraints.

ABSTRACT Under low reagent dosage, the flotation performance of diesel as a collector was enhanced, and the synergistic mechanism of diesel blended with oleic acid and CTAB was investigated. Results showed that compared to pure diesel, the oleic acid blended system (Blend A) increased clean coal yield by 81.52% to 92.24%, while the CTAB blended system (

Direct Ink Writing 3D Printing of Recyclable and Thermally Stable Vitrimers
Vitrimers hold great promise in additive manufacturing as defect‐insensitive, repairable, and recyclable feedstocks. A thin‐film additively manufactured process is developed for a high‐performance vitrimer that is difficult to process traditionally.

ABSTRACT The present work systematically compares the performance differences between two novel homologous materials employed as co‐carbonization agents in the synthesis of mesophase pitch. Low‐cost FCC slurry was used as the raw material, with bio‐tar (BT) and bio‐tar pitch (BTP) as co‐carbonization agents.

Hard Carbon in Alkali Metal Ion Batteries
Analyze the storage mechanism of hard carbon materials in alkali metal ion batteries, explore the relationship between microstructure and performance, and provide countermeasures to improve performance. Hard carbons (HCs) are nongraphitizable and consist of numerous short‐range carbon layers stacked together.
