Constraining snow water equivalent of wet snowpacks in Southeast Alaska

Annals of Glaciology
Quantifying snow water equivalent (SWE) with ground-penetrating radar (GPR) in a warming climate is complicated by the incidence and variability of liquid water in snow.

Shapeshifting Liquid Metal Droplets for Soft Fluidic Machines

Advanced Materials, EarlyView.
This study presented a liquid metal shape shifting strategy which harnesses Lorentz force, surface tension and fluid instabilities to achieve autonomous fluidic power. By using a liquid metal droplet as a mobile current carrier, this strategy enables the development of low‐voltage, self‐oscillating pumps that outperform existing soft pumps.

Tunable and Persistent Macroscopic Polarization in Nominally Centrosymmetric Defective Oxides

Advanced Materials, EarlyView.
This work introduces an approach to defect‐mediated symmetry breaking and built‐in polarization in nominally centrosymmetric defective oxides, Gd‐doped CeO2‐δ films, by controlling macroscopic charge asymmetry. Electric field‐driven asymmetric redistribution of oxygen vacancies induces a switchable, stable polarization, leading to a notable, persistent

Beyond Conventional Cooling: Advanced Micro/Nanostructures for Managing Extreme Heat Flux

Advanced Materials, EarlyView.
This review examines the design, application, and manufacturing of biomimetic or engineered micro/nanostructures for managing high heat‐flux in multi‐level electronics by enhancing conductive, convective, phase‐changing, and radiative heat transfer mechanisms, highlighting their potential for efficient, targeted thermal management, and future prospects.
