Synergistic Regulation of Hierarchical Anode Interphase and Cathode Electronic Structure by a Fe(III) Complex for High‐Performance Aqueous Zinc‐Manganese Battery

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The NGB additive can concurrently address anode and cathode issues during Zn‐Mn battery cycling by constructing a hierarchical interfacial layer on the anode surface to alleviate side reactions and modulate zinc deposition and by incorporating Fe3+ ions into the α‐MnO2 cathode to improve its structural stability and electrical conductivity.

Metal‐Free Halogen‐Engineered Carbon Nanotubes for Highly Efficient Oxygen Reduction Reaction

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
In work employs density functional theory screening to guide the halogen engineering of metal‐free, Cl‐mediated carbon nanotubes for a highly efficient oxygen reduction reaction (ORR). Cl‐mediation optimally tunes the electronic structure and binding energies of oxygen intermediates, delivering an ORR activity rivaling that of commercial Pt/C, high 4e−

Molecularly Engineered Dual‐Crosslinked Polymer Dielectrics for 200 °C Capacitive Energy Storage

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This work establishes a molecular engineering strategy that constructs a robust dual‐crosslinked network in polymer nanocomposites, achieving a record‐high energy density of 5.17 J cm−3 with >90% efficiency at 200 °C. The multiscale‐validated design simultaneously enhances dielectric polarization and introduces deep electron traps, resulting in ...

Linear‐Nonlinear‐Linear Sandwich‐Structured Polymer Composites With Metal‐Organic Framework (MOF)‐Enhanced Insulating Layers and Horizontally Oriented Nanotube‐Filled Polarization Layer for High Energy Storage Performance

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A linear‐nonlinear‐linear (LNL) sandwich dielectric film was rationally designed for high energy storage. Its outer linear layers are MOF (ZIF‐8)‐enhanced PEI composites (EZ), and the middle nonlinear layer is an electrospun‐hot‐pressed P(VDF‐HFP)/TNTs composite (PT) with horizontally oriented TNTs.

Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile

Fire and Materials, EarlyView.
ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Multi‐synergistic strategy for dual‐sensing conductive hydrogels capable of simultaneous strain and temperature monitoring

FlexMat, EarlyView.
In this study, a multicomponent synergistic strategy is utilized, which capitalizes on the “intersection” of multiple functional influencing factors to achieve the successful development of a multifunctional hydrogel. Through the construction of a unique three‐dimensional dynamic cross‐linked network, the material combines mechanical strength ...

Monitoring and assessment for obstructive sleep apnea

FlexMat, EarlyView.
This review systematically classifies Obstructive Sleep Apnea (OSA) monitoring indicators into three categories: physical, biochemical, and electrophysiological indicators, and lists several methods for each category. Abstract Obstructive sleep apnea (OSA) is a common chronic sleep‐disordered breathing disease characterized by recurrent upper airway ...

Review of millimeter‐wave and terahertz near‐field synthetic aperture radar imaging technology

InfoScience, EarlyView.
Abstract This paper comprehensively reviews the development of millimeter‐wave (MMW) and terahertz (THz) near‐field imaging technologies, with an emphasis on the state of synthetic aperture radar (SAR)‐based imaging technologies. Near‐field imaging technologies are categorized into passive and active imaging modes, among which active imaging is favored
