According to the microhardness measurement results, there exists a layer of contamination of about 30 μm into the alloy after the enamel was vitrified for 30 min at 900 °C in air; but the depth of oxygen contamination into the alloy changed little after oxidation for 1000 h at 600 °C.
The narrow peak in the histogram corresponding to the image of the control is indicative of the natural corrugation of graphene, combined with a small layer of contamination from the buffer and deionized water, and environmetal and instrument fluctuations.
Our approach reduces significantly the level of contaminations for supported and suspended graphene layers.
Nonetheless, it should be noted that even in the presence of contamination layer, the localized corrosion resistance of peened alloy was greatly improved, which might be due to surface nanocrystallization, disappearance of rolled 〈220〉 texture and residual compressive stress effects caused by USSP.
The Research Translation Core and Community Engagement Core have created GIS maps of North Carolina Community Garden Partners' garden sites as of 2016 with layers showing various potential sources of contamination using data from EPA's EJSCREEN and C-FERST environmental justice (EJ) exposure mapping tools as well as state databases.
The abdominal wall is closed after lavage of the muscle layers to reduce the risk of contamination.
Layer 3, in turn, was sampled from squares M13-14, arearea where layer 2 was almost sterile and, therefore, the possibility of contamination of the layer 3 faunal assemblage by later material (e.g., as a result of decapage error) could be excluded.
AES indicated only a few percent of Cl contamination of the top layers of the Pb deposit while the contamination by C, O-containing compounds was substantial.
This aSi layer was used to mitigate the risk of contamination for subsequent processes.
To evaluate the effect of silicon-based contamination on the performance of GO after the reduction process, we investigated the double-layer capacitance of reduced GO as a function of contamination.
