Impact of Electrolyte Temperature on Solution‐Combustion Synthesized NiO/Ni Nanoparticles as Oxygen Evolution Reaction Electrocatalyst

ChemistryOpen, Volume 15, Issue 4, April 2026.
Electrolyte temperature significantly affects electrocatalyst performance in water splitting reactions. Catalysts synthesized by solution combustion synthesis were evaluated for oxygen evolution activity at different temperatures. Elevated temperatures reduced overpotential and increased current density, reflecting enhanced reaction kinetics and ...

Mechanism and suppression of breaking overvoltage of DC circuit breakers

High Voltage
The occurrence of breaking overvoltage in a DC circuit breaker (DCCB) poses a potential threat to the safe operation of a DC grid. Based on the structure of the ±10 kV three‐terminal DC distribution network, this paper sets up the medium‐voltage DCCB and

Hierarchical Game‐Theoretic Defense Strategy for Coordinated Attacks in Hybrid AC/DC Cyber‐Physical Power Systems

Energy Internet, Volume 3, Issue 1, Page 52-65, April 2026.
ABSTRACT This paper proposes a game‐theoretic optimisation framework for designing attack and defence strategies in hybrid AC/DC cyber‐physical power systems (CPPS). The proposed framework employs a three‐layer planning hierarchy. The upper layer introduces a novel target importance index combining complex network theory and power flow entropy.

Protection strategy for multi-terminal DC networks with fault current blocking capability of converters [PDF]

, 2017
High voltage dc networks are a promising technology to flexibly transmit power over long distances. However, dc grid protection is still a major challenge. DC fault clearance can be mainly achieved with three devices. These are ac circuit breakers (ACCBs)

Understanding the Autonomous Electric Vehicle Cyber Threat Landscape: A Focus on Infrastructure, Threats and Ontology‐Based Modelling

Energy Internet, Volume 3, Issue 1, Page 39-51, April 2026.
ABSTRACT The development of autonomous electric vehicles (AEVs) represents the convergence of two simultaneous automotive revolutions: electric vehicles (EVs) and autonomous vehicles (AVs). AVs require sensors, decision‐making systems and actuation systems to achieve autonomous driving, whereas EVs require intelligent management and real‐time ...
