Chaotic Combustion in Spark Ignition Engines

, 2002
We analyse the combustion process in a spark ignition engine using the experimental data of an internal pressure during the combustion process and show that the system can be driven to chaotic behaviour.

Ultrastable Photoactive Halide Perovskite Nanocrystal‐Sensitized SnO2 Nanorods for Room‐Temperature NO2 Detection

Advanced Functional Materials, EarlyView.
ABSTRACT Metal oxide (MOx)‐based NO2 gas sensors typically require high temperatures or ultraviolet light, limiting their practical use. To enable visible‐light activation at room temperature, efficient and stable photosensitizers should be integrated with nanostructured MOx hosts.

Engineering Intelligent Graphene Oxide‐Cellulose Membranes: Suppressing Thermal Runaway for a Safer Aqueous Zinc‐Ion Batteries

Advanced Functional Materials, EarlyView.
A novel thermos‐responsive hydroxypropyl cellulose/graphene oxide (HPC/GO) composite membrane is fabricated for reversible temperature‐gated ion transport in aqueous zinc‐ion batteries. Enabled by LCST‐driven structural transition, unimpeded ion diffusion at room temperature delivers high capacity, while elevated temperature suppresses transport; full ...

Silicified Wood‐Inspired, High‐Strength Fire‐Resistant Chitin‐Based Aerogels for Sustainable High‐Temperature Thermal Insulation

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.

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 (
