Support‐Mediated Reversible Redox Dynamics of Pt and Au on CeO2 at Room Temperature

Small, EarlyView.
Atomic‐resolution in situ electron microscopy reveals reversible room‐temperature redox cycling of Pt and Au on CeO2, driven by oxygen‐vacancy‐mediated spillover chemistry. Pt undergoes complete oxidation and reversible wetting–dewetting restructuring with enhanced dispersion, whereas Au shows self‐limiting surface oxidation, highlighting metal ...

Fabrication of BaZr0.1Ce0.7Y0.1Yb0.1O3‐δ Skeleton Structure for the Development of High‐Performance Nanocomposite Cathodes for Protonic Ceramic Fuel Cells by Nitrate Impregnation

Small, EarlyView.
A homologous BZCYYb1711 cathode skeleton was constructed using the same material as the electrolyte, and active components were introduced into the skeleton via nitrate impregnation to form a nanocomposite cathode. This strategy effectively alleviated the thermal expansion coefficient (TEC) mismatches between the cathode and electrolyte.

Quasi‐In Situ 4D‐STEM Mapping of Exsolution Driven Parent Matrix Restructuring in Sr2FeMoO6‐δ

Small Methods, EarlyView.
How does catalytic exsolution alter its parent matrix in realistic solid oxide cells? A beam‐artifact‐free, quasi‐in situ 4D‐STEM methodology maps intrinsic nanoscale transformations in bulk Sr2FeMoO6‐δ electrodes. Correlative identical‐location imaging reveals that surface exsolution inherently couples with profound crystallographic reorganization and

Surface‐driven size scaling of the lattice parameter, Debye–Waller coefficient and microstrain in nanocrystals

Acta Crystallographica Section A, EarlyView.
This work develops three surface‐driven nanoscale models for the diffraction‐derived lattice parameter, Debye–Waller coefficient and microstrain, clarifying why their size dependences are not equally universal. Atomistic simulations and literature data show that lattice parameter trends depend strongly on capillarity, chemistry and defects, whereas the

Phototherapies mediated by metallic nanoparticles and near‐infrared radiation in skin cancer: A systematic review

Photochemistry and Photobiology, EarlyView.
Recent studies demonstrate that near‐infrared (NIR—750–980 nm)‐mediated photodynamic (PDT) and photothermal (PTT) therapies, combined with metallic nanoparticles (MNPs), show promising results against skin cancer, particularly melanoma, in both in vitro and in vivo models.

Exploration of Characteristic Equation Towards the Analysis of Dynamical Stability for Synchronous Generators through Swing Equation

International Journal of Electrical Engineering and Applied Sciences
This study reports a didactic approach on how to exploit the knowledge of the characteristic equations of any second-order system towards their stability analysis. To prove the efficacy of the method in industrial applications, the manuscript focuses on

Design of High‐Performance MnCo1.5Cu0.5O4 Spinel Contact Material with Optimized Electrical Conductivity and Thermal Stability for Solid Oxide Electrolysis Cells by Cu Doping

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
Cu‐doped spinel MnCo1.5Cu0.5O4 exhibits excellent conductivity and stability as SOC contact material. After 1000‐h aging at 850 °C, the contact layer maintains a 10 mΩ cm2 ASR value, and a single‐cell stack achieves a H2O/CO2 co‐electrolysis power density of 0.52 W cm−2.

Atomic Scale Insight Into High Voltage Degradation Mechanism in YSZ Electrolyte for Solid Oxide Electrolyzer Applications

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 5, September 2026.
The evolution of yttria‐stabilized zirconia (YSZ) electrolyte microstructure after testing at progressively high voltages was captured at the micro‐ and atomic‐scale levels to determine the operational boundaries of a solid oxide electrolysis cell (SOEC).
