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.

Gelatin Nanosphere‐Decorated 3D Aramid Nanofiber Hybrid Nanoporous Separators with Regulated Ion Transport for Li‐Metal Batteries

Small, EarlyView.
Gelatin nanosphere‐decorated aramid nanofiber hybrid nanoporous separators with high porosity are fabricated via a phase separation‐induced self‐assembly method. This separator enhances cation transport and regulates ion distribution, enabling the formation of a stable solid electrolyte interphase layer and suppression of Li dendrite growth.

Tailoring Model‐Based Systems Engineering for Sub‐100 g PlanarSats: A Power‐First View Stack

Systems Engineering, EarlyView.
ABSTRACT This paper addresses how to apply model‐based systems engineering (MBSE) to ultrasmall planar satellites under severe power and resource constraints. PlanarSats are sub‐100‐gram spacecraft built as single printed‐circuit boards where the same surface must host both electronics and solar cells, so power generation, geometry, and component ...

Staging concept for aging management: Definition, mechanism, and coping strategies

VIEW, EarlyView.
We divided the overall aging stage into “pre‐aging”, “aging compensation”, and “aging disability”. For each stage, we delineate the clinical presentations, biological phenomena, theoretical underpinnings, and key management priorities. Abstract Aging, as a gradual and largely irreversible biological process, characterized by declining organismal ...
