An Integrated Stainless Steel‐Based Electrode for Durable Direct Natural Seawater Electrolysis

open access: yesAdvanced Materials, EarlyView.
We report an integrated stainless steel‐based electrode featuring Pt atomic clusters anchored on a NiFe‐LDH anticorrosive layer. By regulating interfacial water dynamics to suppress chloride attack, this hierarchical architecture achieves superior durability (over 1000 h) and energy efficiency in direct seawater electrolysis, offering a cost‐effective ...

Perspective: OLED Displays Singing with the Blues

open access: yesAdvanced Materials, EarlyView.
While blue pixels consume approximately 50% of the energy of OLED display front planes, in the 25 years since their invention, 100% internal efficiency triplet‐controlled phosphorescent OLEDs have not met the stability standards necessary for their adoption.

Optimizing Finite Population Mean Estimation Using Simulation and Empirical Data

open access: yesMathematics
Two-phase sampling is an effective sampling approach that is useful in sample surveys when prior auxiliary information is not available. When two variables have an association, the ranks of the auxiliary variable are proportional to the study variable ...

Toward a Consensus Characterization Protocol for Organic Thermoelectrics

open access: yesAdvanced Materials, EarlyView.
We advocate a common consensus on accurate and standardized reporting of performance metrics in the field of organic thermoelectrics. We summarize prevalent issues in the literature and propose a pre‐submission checklist to support the publication of reproducible results.

Ultra‐Sensitive Nanofiber‐Based Triboelectric Nanogenerator for Energy Harvesting and Self‐Powered Sensing

open access: yesAdvanced Materials, EarlyView.
A multidimensional molecular strategy optimizes the tribonegative layer by electrospinning PVDF‐HFP for dipole alignment and crystallinity, followed by 2D borophene doping to enhance conductivity and charge trapping. Integrated with Nylon‐66 nanofibers, the composite device delivers a record sensitivity of 53.8 ± 1.2 V kPa−1 at 3 Hz, enabling ultra ...

Bio‐Inspired Hierarchical Nanoreactor With Hetero‐Coordinated Fe–P–Co Bridges for Whole‐Pathway‐Regulated Electrocatalytic Oxygen Reduction

open access: yesAdvanced Materials, EarlyView.
A bioinspired Co‐doped Fe2P on N‐doped carbon with a hierarchical eucalyptus‐like nanoarchitecture is engineered to regulate oxygen across the entire electrochemical pathway, achieving a half‐wave potential of 0.938 V vs. RHE, sustaining 373 h of discharge in Al‐air batteries, and delivering an energy density of 3487 Wh/kg.
