The following soil factors were varied: The ratio between the clay minerals and the rock forming mineral quartz and feldspar; The influence of humic acid, hornblende and iron (III) hydroxides; the salt concentration in the porewater, the pH of the soil and the effect of non-oxidizing ...
This is considered as an advantage in using hydrazine as a reducing agent, whereas effects of the aqueous solution of hydrazine include corrosion to eyes, skin, and mucous membranes upon contact, and it is a probable human carcinogen. Furthermore, hydrazine fumes attack the nose and throat upon...
Preston's equation is very useful for evaluating a polishing operation. ⅆTⅆt=k.p.ⅆsⅆt, where k is the Preston coefficient and p is the polishing pressure. This equation implies that the velocity of the surface recession, dT/dt, is related to the relative velocity between the ...
Corrosion Resistance: A material’s ability to withstand environmental degradation without losing strength, primarily through its composition and treatment. Acidity and Alkalinity: The pH value of a material indicates its acidity or alkalinity, which affects how it interacts with other materials. For eng...
Activity coefficients were determined by the Debye-Huckel equation. Rutherfordine (UO2CO3) was predicted to precipitate from pH 4 to pH 7, whereas calcite was predicted to precipitate at pH 8. Advertisement 5. Uranium oxidation and reduction The reducti...
from the acidic medium, rinsed with bi-distilled water, air dried, and precisely re-weighed. All measurements were performed in triplicate to ensure the reproducibility of the results. Average weight loss values (\(\Delta W\)) were recorded and the corrosion rate was calculated using equation24...

Recent research has shown that contamination by trace metal ions, such as Fe2+ and Cu2+, originating from the corrosion of the metal bipolar plates or end plates can strongly accelerate membrane thinning and performance decay in a PEM fuel cell by catalyzing radical formation reactions. These cat...
Chlorinated organic compounds (COCs) are common anthropogenic contaminants encountered in soil and groundwater. COCs were industrially produced for different applications, such as dry cleaning, degreasing, or as pesticides. The presence of COCs in the en
