Interfacial Salt Redistribution Enables Rapid Atmospheric Water Harvesting in a Biomimetic Multi‐Layer Hygroscopic Membrane

open access: yesAdvanced Science, EarlyView.
A biomimetic multi‐layer hygroscopic membrane redistributes salt toward an air‐accessible nanofiber interface, enabling rapid interfacial deliquescence while a brush‐like hydrogel promotes efficient liquid transport and storage. By decoupling vapor capture from bulk water storage, the membrane achieves fast sorption kinetics and enables rapid‐cycling ...

Effects of Various Bipolar Approximations of Active Regions on Solar Surface Magnetic Field Simulations

open access: yesThe Astrophysical Journal
The evolution of solar surface magnetic fields is essential for understanding solar activity and the underlying dynamic process. The surface flux transport (SFT) model is a widely used and effective tool for simulating this evolution.

Ionically Counter‐Programmable Phase‐Separation of Superstable Star‐Biopolyamide Coacervates for Electrothermally‐Responsive Pseudosolid Smart Windows

open access: yesAdvanced Science, EarlyView.
We develop bio‐based, star‐branched polyamides from itaconic acid and cadaverine with tunable lower critical solution temperature (LCST) transitions for dynamic solar modulation. Specific metal ion coordination with pyrrolidone moieties drives precise phase transitions via calcium‐induced salting‐in and sodium‐induced salting‐out mechanisms. Formulated

Martian Crustal Magnetic Field Effects on the Ionospheric Main Peak

open access: yesThe Astrophysical Journal
Planetary magnetic fields can affect ionospheric plasma transport and coupling with the solar wind. In contrast to the terrestrial global magnetic field, there are only weaker and sporadic crustal magnetic fields on Mars. Many studies have indicated that

Toward Rational Design of Aqueous Battery Membranes Beyond the Selectivity‐Conductivity Trade‐Off

open access: yesAdvanced Science, EarlyView.
This review examines sulfonated membranes for redox flow batteries. It focuses on proton transport mechanism, membrane design, performance limits, optimization strategies, and the pathway from molecular design to membrane manufacturing. ABSTRACT Electrochemical energy‐storage systems increasingly require membranes that can simultaneously deliver fast ...

Habitat‐Specific Design Strategies for Untethered Soft Robots

open access: yesAdvanced Science, EarlyView.
Habitat shapes the design of untethered soft robots. Across land, water, air, and living tissues, environmental constraints govern viable combinations of compliant structures, actuation mechanisms, and energy delivery. This review connects these constraints with robotic performance and identifies design principles for advancing adaptable, durable, and ...
