D–F Difference Raman spectra calculated between noninfected (Control) and virus-infected cells (MeV and SARS-CoV-2 taken together) for D cytoplasm, E Golgi-mitochondria, and F nucleus region of the Vero E6 cells. G–I Difference Raman spectra calculated between the SARS-CoV-2-infected cells...
The paste containing pyrite showed evidence of internal sulfate attack, through a reduction in mechanical strength and presence of microcracks with ettringite verified by FEG SEM/EDS. Nanomagnetite increased the mechanical strengths, verified by the pore filling and formation of more chemically stable ...
All observations were carried out using a IMIX-PC analyzer and Prism detector (Bruker AXS, Ewing, NJ) and field emission scanning electron microscope FEG XL30 (FEI Co., Hillsboro, OR). Spectra were acquired for 30 s at an accelerating voltage of 15 kV and spot size of 5. Quantification ...

The crystallinity and elemental composition were explored via focused ion beam (Quanta 3D FEG, FEI, Eindhoven, Netherlands) milling at 0.1 nA and 30 kV and by FE-TEM (JEM−2100F, Jeol, Tokyo, Japan) in conjunction with energy-dispersive X-ray analysis (EDX) at an accelerating voltage of...
More than 20 years ago, pSi multilayers were produced [35,36] by the utilization of another of its important properties; the fact that already etched porous layers are not affected during the electrochemical anodization, i.e., cSi dissolution occurs only at the etching front, which is the ...

The effect of pressure on the naturally occurring hydroxide-perovskite stottite, FeGe(OH)6, has been studied in situby micro-Raman spectroscopy to 21 GPa at 300 K. The ambient spectrum contains six OH-stretching bands in the range 3064 3352 cm–1. The presence of six non-equivalent OH ...
