Comprehensive Analysis of the Degradation Phenomena of Proton Exchange Membrane Water Electrolyzers with Iridium on Antimony Tin Oxide Anodes

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
This study examines the structural and chemical evolution of low‐loaded Ir/ATO anodes during PEM water electrolysis under realistic conditions. Iridium dissolution is largely suppressed. In the early stages, both ionomer and support degradation are detected. Morphological reorganization occurs at the interface between the anode catalyst layer (ACL) and

RuO2‐Based High‐Entropy Oxide and Its Asymmetric Catalysis on Polysulfide Conversion in Lithium–Sulfur Batteries

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
RuO2‐based high‐entropy metal oxide shows an asymmetric catalysis on polysulfide conversion with an inferior kinetics enhancement of polysulfide generation, but a superior promotion of Li2S deposition, which greatly favors the inhibition of shuttle effect and the improvement of battery performance. High‐entropy oxides with five or more metal components

A Boric Acid‐SnO2 Composite for Interfacial Stabilization of Highly Efficient Perovskite Solar Cells

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
The interaction between BA and FAI can inhibit the oxidation of iodide ions to elemental iodine (I2) in perovskite films, significantly improving the films' UV stability, and the power conversion efficiency (PCE) of the device containing BA reaches 25.7%.

Constructing Interface‐Enhanced S‐Heterojunctions Via Surface Functionalization Strategies to Improve Photocatalytic Hydrogen Production Efficiency in Inorganic/Organic Composite Systems

open access: yesENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
A surface in situ growth strategy was employed to fabricate a COF/TiO2 S‐scheme heterojunction with enhanced interfacial forces. This enhanced interfacial heterojunction significantly improved photocatalytic hydrogen production capacity. S‐scheme heterojunctions play a crucial role in enhancing charge‐carrier separation efficiency and redox capability.

High‐Titanium Zircon Rims in Rhyolite – A Reflection of Adiabatic Ascent?

open access: yesGeological Journal, EarlyView.
The ascent of granitic magma from source to emplacement is rapidly achieved through dyking, resulting in negligible heat loss to the surrounding wallrock (i.e., adiabatic). Zircon growth during ascent can record the changing magma conditions including adiabatic cooling and heating, resulting in high titanium rims on low titanium cores without ...

Geochemical and Geological Investigation of Skarn‐Type Pb–Zn Mineralization in Hastanetepe (Balya‐Balıkesir, Türkiye): An Approach Based on Fluid Inclusions, Sulphur Isotopes and Geochemical Data

open access: yesGeological Journal, EarlyView.
Integrated petrographic, mineralogical and geochemical data from the Hastanetepe Pb–Zn deposit (Balya, Türkiye) reveal multi‐stage hydrothermal alteration and a magmatic sulphur source. Fluid inclusion and sulphur isotope results indicate a complex fluid evolution responsible for skarn‐type Pb–Zn mineralization along limestone–dacite contacts ...

Intelligent materials for on‐demand electromagnetic absorption

open access: yesInfoMat, EarlyView.
This review introduces an innovative “stimulus‐state‐property” paradigm, facilitating a fundamental transition from static to dynamically intelligent electromagnetic wave absorption (EMWA). The key advancement lies in the synergistic integration of external fields with structurally engineered metamaterials and tunable components.
