Corticosterone and Mitochondrial Efficiency Are Associated With Changes in DNA Oxidative Damage During an Acute Stress Response in Leach's Storm‐Petrels (Hydrobates leucorhous)

Journal of Experimental Zoology Part A: Ecological and Integrative Physiology, EarlyView.
ABSTRACT The ability of organisms to effectively respond to challenges is critical for survival. We investigated how an acute stressor affected corticosterone, mitochondrial function, and DNA oxidative damage in a wild population of Leach's storm‐petrels (Hydrobates leucorhous).

Cold Gas Sprayed Titanium Coating for Corrosion Protection of Bipolar Plates in Proton Exchange Membrane Water Electrolysis

Materials and Corrosion, EarlyView.
Climate‐neutral green hydrogen is produced via water electrolysis using renewable energy. This study explores using cold gas spraying to apply titanium coatings on steel bipolar plates for proton exchange membrane water electrolyzers. The coating shows effective corrosion protection, presenting a promising solution for future designs.

Fault Diagnosis of Proton Exchange Membrane Fuel Cells

2021 5th International Conference on Control and Fault-Tolerant Systems (SysTol), 2021
Failures caused by load cycling significantly limit the reliability and durability of proton exchange membrane fuel cells (PEMFC) in vehicular applications. Improper management of load cycling accelerates cell degradation and can lead to severe material attenuation.
