Hydrogen evolution, efficiency and exacerbated galvanic corrosion damage of magnesium alloy anode

open access: yesCailiao gongcheng, 2021
To address the galvanic corrosion issue that is critically limiting the practical application of Mg alloys, the negative difference effect (NDE), anodic dissolution efficiency, and anodic hydrogen evolution were investigated by means of the hydrogen ...

The anodically polarized Mg surface products and accelerated hydrogen evolution

open access: yesJournal of Magnesium and Alloys, 2023
To clarify the anodic dissolution mechanism of Mg, the hydrogen evolution from pure Mg in acidic solutions under galvanostatic conditions were systematically measured. With increasing anodic current density, the cathodic hydrogen evolution rate decreased,

Daytime F2-layer negative storm effect: what is the difference between storm-induced and Q-disturbance events? [PDF]

open access: yesAnnales Geophysicae, 2007
Negative F2-layer storms related to geomagnetic activity and quiet-time disturbances (Q-disturbances) belong to different classes of events and exhibit different morphology.

Investigation of pitting corrosion and hydrogen evolution of aluminum and AA2024 alloy by simultaneous electrochemical measurements and imaging

open access: yesElectrochemistry Communications, 2021
To investigate the “negative difference effect” (NDE) in the anode hydrogen evolution process that is accompanied by pitting corrosion of aluminum, an electrochemical real-time data acquisition device was designed and used.

Effect of a very low negative dietary cation-anion difference (DCAD) diet on plasma and urine metabolomics of prepartum Holstein cows

open access: yesJDS Communications, 2022
The objectives of this cross-sectional, nonintervention, observational study were to compare urine and blood parameters between cows consuming a positive dietary cation-anion difference (DCAD) diet [early dry cows, DCAD + 250 mEq/kg of dry matter (DM), n

COVID-19 and Gender Differences in Social Trust: Causal Evidence from the First Wave of the Pandemic

open access: yesSocius, 2022
Although research provides causal evidence on the effects of COVID-19 lockdown measures on trust, causal effects of infection risks are missing. To contribute to increasing research on the societal consequences of the COVID-19 pandemic, we estimate ...
