The morphologies of these catalysts were acquired using a Hitachi FE-SEM S-4800 SEM operated at 1.0 kV. High-resolution transmission electron microscopy (HRTEM) images were taken on a JEOL JEM-2100F TEM operated at 200 kV. Scanning transmission electron microscopy (STEM) was carried out ...
increases, the length of individual sections increases, but their ratio to the pulling distance remains more or less constant (around 0.2 for the 1st section, approximately 0.6 for the 2nd section, and approximately 0.2 for the 3rd section). As the pulling distance increases, not only the maxim...
Standard error of the mean (SEM) of particulate elements was calculated by taking the standard deviation and dividing by the square root of the sample size, and it is given for all sampling points. Detailed linear regression and elemental correlation matrix analysis were performed in Excel....
Shakti Dubey tops civil services exam; Harshita Goyal, Dongre Archit Parag get 2nd, 3rd ranks: UPSC CNM News Shakti Dubey has topped the civil services examination 2024, results of which were declared on Tuesday by the Union Public Service Commission (UPSC). Dubey has done her graduation (Bach...
a Cross-sectional SEM image, b a corresponding EDX elemental distribution map, and c EBIC image (in which the EBIC values are given by false colors), acquired at the identical position of a ZnO:Al/(Zn,Mg)O/CdS/CIGSe/Mo/glass stack. The EDX map is composed of signals from Ga-L (or...
XRD and SEM analysis showed that the dry ground samples had rougher surfaces (larger surface area), which contributed to them containing lower amounts of crystallographic planes with higher quantities of broken Al-O bonds, that have been shown to be closely related to the fatty acid collector ...

Optical Microscopy (OM), Scanning Electron Microscopy (SEM), and Transmission Electron Microscopy (TEM) were employed for the observation of both macro- and microstructures. Metallographic samples underwent sequential procedures, including cutting with a line-cutting machine, rough grinding, fine grinding...
ultraviolet (UV) spectrum, while narrow bandgap semiconductors such as Cu2O show activity in the visible NIR range; however, the band potentials of Cu2O semiconductors are not conducive to mediating both reduction and oxidation reactions simultaneously. As a result, single-component systems have lower...
The results from Optical Microscope, SEM, XRD analysis, and Thermo-Calc simulation were used to identify the microstructure formed after the aging process. Testing for hardness and tensile strength was conducted, in addition to corrosion testing. It was found that Mg significantly impacts the ...
