Advanced Functional Materials, EarlyView.Inspired by natural silicified wood, a biomimetic mineralized chitin‐derived aerogel is constructed. It can withstand 81 000 times its own weight, and its backside temperature is 130.4°C after exposure to ∼1300°C butane flame for 600 s, exhibiting high‐strength, fire‐resistance, and super thermal‐insulation properties.

Vibrations of Fluid-Structuré Coupled Systems
, 1991 It is proposed to investigate alternative symmetric formulations valid for static and modal analysis based either on the representation of the liquid by a pressure field and a displacement potential field, either on the representation of the structure by a displacement field and a reaction force (or acceleration) field.

Solvent Co‐Intercalation Enabled Ca Storage in MoS2 for Ca‐Ion Batteries
Advanced Functional Materials, EarlyView.Regulating electrolyte solvation levels enables otherwise non‐intercalatable Ca2+ ions to reversibly co‐intercalate into molybdenum disulfide (MoS2) as ether‐solvated species. The intercalation reversibility is strongly governed by solvent chain length, as demonstrated using diethylene glycol dimethyl ether (G2) and tetraethylene glycol dimethyl ether (
