Advanced Separators for Liquid and Quasi‐Solid Lithium Rechargeable Batteries: Design and Development

Advanced Materials, EarlyView.
This review traces the evolution of lithium‐ion battery separators from passive barriers to multifunctional components central to cell safety and performance. Polymer‐ceramic hybrids, nanofiber architectures, and bio‐derived membranes deliver ionic conductivities above 3 mS cm−1, thermal stability beyond 200 °C, and effective suppression of lithium ...

Study on the influence of enclosed vertical channels on downward flame spread over XPS thermal insulation materials

Case Studies in Thermal Engineering, 2019
In this paper, the small-scale combustion experiments are carried out in combination with theoretical analysis to study the influence of length-width ratio (α) of enclosed vertical channel on the downward flame spread of XPS insulation material attaching

Small-scale Interaction of Turbulence with Thermonuclear Flames in Type Ia Supernovae [PDF]

, 1999
Microscopic turbulence-flame interactions of thermonuclear fusion flames occuring in Type Ia Supernovae were studied by means of incompressible direct numerical simulations with a highly simplified flame description.

Strong Lateral Confinement of Hydrophilic Silica Nanoparticles on Mg‐Al Layered Double Hydroxides Nanoflakes for Enhanced Thermal Properties

Advanced Materials Interfaces, EarlyView.
A nanostructured, naturally flame‐retardant, and non‐toxic inorganic composite is introduced, which is laterally associated with silica nanoparticles to induce the restacking of the LDH lamella structure, thereby serving as an efficient thermal insulator.

Water‐Stable Paper‐Based Laser‐Induced Graphene With Asymmetric Water Adhesion and Wettability

Advanced Materials Interfaces, EarlyView.
Paper‐based electronics are attractive for sustainable and disposable devices, but often fail in wet environments. By introducing Parafilm into cellulose paper combined with laser conversion, two graphene surfaces with different water interactions are created.

Chemically Doped Conductive Polymers for Wearable Health Monitoring

Advanced Materials Technologies, EarlyView.
Among conductive polymers, poly(3,4‐ethylenedioxythiophene):poly(styrenesulfonate) (PEDOT:PSS), polyaniline (PANI), and polypyrrole (PPy) are the most studied and applied. Chemical doping significantly boosts intrinsic conductivity and mechanical robustness.
