Design Strategies and Emerging Applications of High‐Performance Flexible Piezoresistive Pressure Sensors

Advanced Functional Materials, EarlyView.
Flexible piezoresistive pressure sensors underpin wearable and soft electronics. This review links sensing physics, including contact resistance modulation, quantum tunneling and percolation, to unified materials/structure design. We highlight composite and graded architectures, interfacial/porous engineering, and microstructured 3D conductive networks

Efficient Membranes Made of a Nanohybrid of Fluorine‐Doped Carbon Dots Coupled With Metal Organic Framework for High‐Performance Vanadium Redox Flow Battery

Advanced Functional Materials, EarlyView.
A sulfonated poly(ether ether ketone)‐based hybrid membrane is fabricated with fluorine‐doped carbon dot (FCD) and functionalized metal organic framework (MIL−101−NH2). The novel design reduces unwanted ion crossover while maintaining a sufficient proton transport pathway.

Thermal expansion in carbon nanotubes and graphene: nonequilibrium Green's function approach

, 2009
The nonequilibrium Green's function method is applied to investigate the coefficient of thermal expansion (CTE) in single-walled carbon nanotubes (SWCNT) and graphene. It is found that atoms deviate about 1% from equilibrium positions at T=0 K, resulting

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 (

Evolution of constrained layer damping using a cellular automaton algorithm

, 2008
Constrained layer damping (CLD) is a highly effective passive vibration control strategy if optimized adequately. Factors controlling CLD performance are well documented for the flexural modes of beams but not for more complicated mode shapes or ...
