An Integrated Stainless Steel‐Based Electrode for Durable Direct Natural Seawater Electrolysis
Advanced 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
Advanced 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
MathematicsTwo-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
Advanced 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.

Advanced 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 ...
