Topology‐Orchestrated Multi‐physical Energy Control in Turtle Shell‐Inspired Metamaterials

open access: yesAdvanced Materials, EarlyView.
A turtle shell‐inspired lattice metamaterial efficiently manages acoustic, fluid‐thermal, and mechanical energy flows simultaneously. The unique hybrid‐coupling architecture achieves superior sound attenuation via pore‐cavity resonance, facilitates effective airflow transport, and maximizes mechanical energy absorption through multistage cell ...

High‐Entropy Ceramic‐Enhanced Deformable Triboelectric Nanogenerator for Noncontact Biomechanical and Raindrop Energy Harvesting

open access: yesAdvanced Materials, EarlyView.
A large‐area, deformable high‐entropy‐ceramic (HEC)‐doped triboelectric nanogenerator with a trilayer architecture is developed, consisting of an HEC‐doped triboelectric layer, a graphite‐like textile charge‐storage layer, and stretchable carbon black electrodes.

Fluorinated Deep Eutectic Gel Electrolytes with Simultaneously Enhanced Mechanical Strength and Ionic Conductivity for Solid‐State Lithium Metal Batteries

open access: yesAdvanced Materials, EarlyView.
The synergistic integration of rigid polyacrylamide (PAM) and flexible poly(N,N‐dimethylacrylamide) (PDMA) phases offers exceptional toughness to suppress lithium dendrites, simultaneously enhancing mechanical strength and ionic conductivity. ABSTRACT Gel polymer electrolytes for lithium‐metal batteries face an inherent trade‐off between mechanical ...

Species-environment relationship in the herb-subshrub layer of a moist Savanna site, Federal District, Brazil

open access: yesBrazilian Journal of Biology
The soils are seasonally or permanently saturated in the moist grassland savanna, locally known as Campo Limpo Úmido. Soil moisture variation seems to determine spatial distribution of communities.

Controlling Radiative Phonons in the van der Waals Ferroelectric NbOI2

open access: yesAdvanced Materials, EarlyView.
Using a simple mirror geometry, this work demonstrates local‐density‐of‐optical‐states control of THz phonon emission in van der Waals ferroelectric NbOI2. By engineering the photonic environment, the phonon Q‐factor, linewidth, peak frequency, and emission intensity are reversibly tuned by over an order of magnitude, revealing radiative phonons as ...

Resolved Convection in Hydrogen-rich Atmospheres

open access: yesThe Planetary Science Journal
In hydrogen-rich atmospheres with low mean molecular weight (MMW), an air parcel containing a higher-molecular-weight condensible can be negatively buoyant even if its temperature is higher than the surrounding environment.

Ultrathin Hydrogel Membranes Inspired by Soap Films Enable Physiologically Relevant Breathing Lung Models

open access: yesAdvanced Materials, EarlyView.
A soap‐film inspired strategy enables the fabrication of ultrathin yet robust GelMA‐PAAm membranes for breathing lung culture. The hydrogel membrane supports long‐term cyclic deformation under air‐liquid interface conditions, enabling physiologically relevant breathing motions of engineered lung tissue culture. ABSTRACT Breathing continuously stretches

Cu‐Pd Dual Single Atoms Promoting Selective CO2 Photoreduction to C2 Products in Seawater

open access: yesAdvanced Materials, EarlyView.
Cu and Pd dual single atoms anchored on TiO2 cooperatively enhance C─C coupling during CO2 photoreduction in seawater. Under xenon‐light irradiation and without a sacrificial reagent/alkaline trapping agent, the catalyst achieves highly selective acetic acid formation.
