SEM micrographs revealed some fluctuation in average grain size as well as corresponding changes in the homogeneous structure and irregular shapes as Sn concentration increased. As a result, the average grain size and crystallite size were optimized to 45.69 nm and 0.66 µm, respectively. ...
If the energy were recovered, this would result in the life cycle energy use in producing methanol being reduced from 47 MJ/kg to 17 MJ/kg [27]. De Marco et al. [33] introduced an improved scenario involving the recovery of a portion of ethanol (33% or 66%) from the water/ethanol...

[18] reported a similar result after comparing a larger number of paints on the same 2 substrates, suggesting that this greater colour change in brick may be related to 1) the fact that the paint layer in brick mockups was thinner than in concrete mockups and 2) the separation between the...

Nonetheless, according to the EIS data and SEM examination, there is no damage of the underlying AA2024-T3 substrate. Conversely, a much lesser cracked surface and no coating detachment was observed for the SCA-GTS-Ce coating, thus confirming its high stability during the corrosion process, as...
have the remarkable property of undergoing a phase transition from solution to solid under shear flow. Our results demonstrate that the shear force within a droplet-microfluidic device can result in the formation of asymmetric tubular-like microgels. Using a combination of FTIR and cryo-SEM, it wa...
These steps result in forming a urea-functionalized sol-gel surface bonded coating for microextraction, as illustrated in FIG. 2A to 2C. Characterization of the exemplary BHEA-BPU sol-gel coating for CME: FIG. 3A to 3D and Table 1, below, provide the results of XPS analysis of the ...
Thus, with an increase in grain size, there will be a decrease in the surface-to-volume ratio, and when the Fig. 5 SEM images of S nO2 coating, a SnO2-1, b SnO2-2, and c SnO2-3 1621 Page 6 of 13 J Mater Sci: Mater Electron (2024) 35:1621 ...
As a result, the melting point of the mixture is reduced considerably (Hasanuzzaman et al. 2016a, b). The thermal expansion coefficient of glass with a high alkali content is increased by around 20 times. To promote the mixture's insolubility, calcium oxide (CaO) is intro- duced (...
