Nature of Surface Microcracks on Phosphorus Micro‐Alloyed Copper
SSRT tests and microscopic characterization methods were used to study the effect of plastic deformation and environment on the formation of surface microcracks on Cu‐OFP. Results show that, while ambient conditions produced thousands of microcracks per mm2, exposure to sulfide water resulted in fewer microcracks with no evidence of crack growth ...

Assessment of Electrical Resistance Sensors Sensitivity to Localized Corrosion
Are electrical resistance (ER) sensors reliable for localized corrosion detection? This study combines analytical modeling and experimental validation to show the vulnerability of ER sensors. The results demonstrate significant underestimation of the true corrosion depth of localized attacks depending on defect's geometry.

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.

Analysis of Corrosion and Wall Perforation in the Heat Exchanger Made of AISI 316L Stainless Steel
Elevated passivation temperature is identified as the dominant factor triggering localized corrosion and subsequent perforation of AISI 316L heat exchanger tubes. Electrochemical and complementary characterization results show that the alloy retains high resistance to general, pitting, and intergranular corrosion, indicating that failure primarily ...

Evaluation of electrolyzed water to control fungal trunk pathogens in grapevine nurseries
Electrolyzed water treatments could have promising applications in the grapevine nursery process to prevent or reduce infections caused by fungal trunk pathogens on grapevine propagation material. Abstract BACKGROUND Grapevine producers demand solutions to control fungal trunk pathogens (FTPs) in nurseries.

This paper describes the Met Office's new lightning location system LEELA. A brief overview of the upgraded hardware and geolocation algorithms is given. LEELA has improved lightning detection capabilities, especially at night. When comparing LEELA to the previous ATDnet system against ground truths LEELA has 100% storm detection efficiency within 5 km

Metal/Si Nanowire Arrays for Hot Electron Catalysis
Silicon nanowire arrays enhance plasmon‐driven catalysis by strengthening light–matter interactions on Au and Ag nanostructured coatings. Hotspot accessibility, rather than near‐field intensity alone, governs photocatalytic performance, while Ag nanoshells exhibit superior activity. The work establishes high‐surface‐area Si nanowire arrays as versatile

Cu+‐Driven Formate Selectivity in Oxidation‐State‐Dependent CO2 Reduction on Cu2O|Graphene
A Cu2O|graphene heterostructure enables interfacial electronic self‐regulation that stabilizes catalytically active Cu+ species under cathodic CO2 reduction conditions. Suppressed over‐reduction preserves structural integrity and promotes *OCHO pathway, resulting in durable and highly selective electrochemical conversion of CO2 to formate.

Silver‐Modulated Copper Dynamics Under Pulsed Tandem Electrochemical CO2 Reduction
Under pulsed CO2 reduction, Ag does more than provide CO for tandem catalysis. It redirects how Cu dissolves, redeposits, and remains catalytically relevant, generating an Ag‐rich yet Cu‐active working state. Correlative surface and solution analysis reveal that tandem performance emerges from dynamic material redistribution rather than from a static ...
