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

Small, 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

Small, 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

Small, 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.

Defects That Magnetize Beyond Monolayer PtSe2

Small, EarlyView.
The presence of a complex point defect consisting of a Pt vacancy (black circle) and a PtSe antisite (red circle) revives and increases the quenched magnetism in bilayer PtSe2. Magnetic properties can be further modulated by the presence of an Se vacancy (blue circle), which can convert the ferromagnetic behavior into antiferromagnetic when it occurs ...
