GB/T 37131-2018e Nanotechnologies—Test method of semiconductor nanopowder using UV-Vis diffuse reflectance spectroscopy GB/T 37131-2018(英文版) Nanotechnology - Testing method of UV-visible diffuse reflectance spectrum of semiconductor nanopowder materials...
The surface composition and binding energy of the samples were determined by X-ray photoelectron spectroscopy (XPS, Perkin Elmer PHI 5600). The shift of the binding energy owing to relative surface charging was corrected using the C 1 s level at 284.6 eV as an internal standard and Ar1 ...
Furthermore, the structural properties of camouflage, chromatic compound identification and related chemometric analysis can be executed by scanning electron microscopy (SEM), Fourier transform infrared spectroscopy (FTIR) and UV–Vis-NIR spectrophotometer for laboratory stage trialing (Aleksandra et al.,...
As observed, the crystallite size of TiO2 anatase (1 0 1) was decreased from 33.072 nm to 27.560 nm with the increase in of rGO concentration from 0 to 5 wt%. This implies that crystallite size increases as the diffraction peak narrower and becomes more distinct. Raman spectroscopy analysis...
The Tiny Big Difference: Nanotechnology in Photoprotective Innovations – A Systematic Review Article 07 September 2024 Background Sunlight is one of the main harmful exogenous factors that induce the reactive oxygen species (ROS) formation. Infrared energy (above 760 nm), visible light (400–...
X-ray photoelectron spectroscopy (XPS, PHI-5702, Physical Electronics) was performed using a monochromated Al Ka irradiation. The chamber pressure was ~3 × 10−8 Torr under testing condi- tions. The morphologies of different samples were observed by transmission electron microscopy (...
The structural, morphological and optical properties of the samples were systematically characterized by X-ray diffraction, scanning electron microscopy, Fourier transform infrared spectra, transmission electron microscopy, Micro-Raman, photoluminescence, and ultraviolet-visible spectroscopy. The as-prepared ZnO...
