Hierarchically Biporous Wick Vapor Chamber With Micro/Nano Condenser for Exceeding 600 W/cm2 Heat Dissipation

open access: yesSmall, EarlyView.
An integrated vapor chamber couples a hierarchically biporous copper wick with a micro/nano‐textured superhydrophobic condenser to form a self‐sustained liquid–vapor loop. The device dissipates extreme heat fluxes above 600 W/cm2, even when the condenser is above the heater, by overcoming the permeability‐capillarity trade‐off in conventional vapor ...

Exploiting Device Deformability for Fluid and Particle Manipulation

open access: yesSmall, EarlyView.
Deformable devices enable fluid and particle manipulation modes that are inaccessible to rigid platforms. This review examines soft materials and architectures that translate controlled deformation into microscale fluid operations such as pumping, valving, mixing, and particle handling.

Synergizing Polysulfide Trapping and Fast Ion Kinetics Enabled by Poly(Acrylamide‐co‐Lithium Acrylate) Aqueous Binder for High‐Sulfur‐Loading Lithium–Sulfur Batteries

open access: yesSmall, EarlyView.
A water‐soluble AmLA binder anchors lithium polysulfides and reinforces sulfur cathodes by combining amide and lithium acrylate functional groups. The dual‐function network retards polysulfide dissolution in operando and preserves electrode integrity under large volume changes.

Physical Anchoring‐Assisted Mechanically Guided Assembly for Material‐Independent 3D Mesostructures

open access: yesSmall, EarlyView.
Conventional mechanically guided 3D assembly relies on selective chemical bonding between 2D precursors and elastomeric substrates, imposing fundamental limitations on material compatibility and scalability. Here, we present a physically anchored, buckling‐guided assembly platform based on a rod array patterned elastomeric substrate (RPES).

Manganese Oxide Catalysts for Lithium–Oxygen Batteries: Structures, Mechanisms, and Reaction Pathway Engineering

open access: yesSmall, EarlyView.
How do the morphologies, crystal structures, and electronic properties of manganese oxides influence oxygen reaction pathways in lithium–oxygen batteries (LOBs)? This review systematically summarizes structure‐dependent catalytic mechanisms and recent engineering strategies, highlighting how defect engineering, compositional modulation, and reaction ...
