A Review of Overcurrent Protection in Smart Grids Under Cyber‐Physical Threats With a Cyber‐Physical Evaluation Framework

Energy Science &Engineering, Volume 14, Issue 8, Page 3948-3973, August 2026.
By manipulating current and voltage measurements, an assailant can induce unwanted relay action while attempting to avoid detection. Detecting advanced cyber intrusions in power protection environments requires specialised data analysis and anomaly detection methods.

Regulating Ligand‐to‐Metal Charge Transfer in UiO‐66(Zr)‐NH2 With Site‐Isolated Cu+ Centers for Efficient Photocatalytic H2O2 Generation

Small Science, Volume 6, Issue 8, August 2026.
Incorporation of highly dispersed Cu species into UiO‐66(Zr)‐NH2 introduces a competing ligand‐to‐Cu charge–transfer pathway that suppresses charge recombination and enhances photocatalytic H2O2 production. Combined PL, TRPL, TRIR, and variable‐temperature FTIR analyses reveal Cu‐mediated modulation of excited‐state dynamics and oxygen reduction ...

Scalable Coating of Spatially Uniform WBG Perovskites via Inhibiting SAM Aggregation for Flexible All‐Perovskite Tandem Modules

Small Science, Volume 6, Issue 8, August 2026.
Perovskite wettability on self‐assembled molecule (SAM) layers is improved by inhibiting SAM aggregation through the introduction of a NiOx interlayer. This enables spatially uniform coating of wide‐bandgap perovskite films onto 5 × 5 cm2 flexible substrate via doctor‐blade coating.

Energy Refurbishment of an Office Building with Hybrid Photovoltaic System and Demand-Side Management

Energies, 2017
On-site photovoltaic (PV) and battery systems intend to improve buildings energy performance, however battery costs and monetary incentives are a major drawback for the introduction of these technologies into the electricity grids. This paper proposes an

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

ENERGY &ENVIRONMENTAL MATERIALS, Volume 9, Issue 4, July 2026.
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

Defect Passivation via Plasma Modification of Lead Halide Perovskite Thin Films

Progress in Photovoltaics: Research and Applications, Volume 34, Issue 7, Page 813-820, July 2026.
We demonstrate that exposure of perovskite thin films to diffuse coplanar surface barrier discharge nitrogen plasma leads to an increase in photoluminescence, attributed to reduced defect densities. This results in implied open‐circuit voltage improvement of up to 80 mV and finalized solar cell open‐circuit gains up to 60 mV.
