Graphene oxide (GO) is a promising material for energy storage device applications. Modified Hummers method (MHM) has been used to prepare GO films from graphite flakes by Sol-Gel method. With the aid of bridging agent dimethyldichlorosiline, structurally fine GO films were prepared. Fourier tran...
FT-IR and XPS analysis demonstrated that the high adsorption of U(VI) on GO/Al2O3 was attributed to the various oxygen-bearing functional groups. In addition, the nano Al2O3 was transferred to amorphous AlO(OH) mineral phase by XRD pattern, which provided the additional reactive sorption ...
The fluorescence spectrum of the compound was studied at different excitation wavelengths in the dimethylsulphoxide solvent. The stability of the molecule by intramolecular electron transfer by hyperconjugation was studied with the natural bond orbital analysis. Frontier molecular orbitals and molecular ...
Even when considering the conventional rule-based XRD analysis, it would be difficult to correctly evaluate the relative fraction of each constituent phase in a mixture sample compared with use of the relatively easier process for only phase identification. This is also true for the data-driven XRD...
作者: MCA Nono,RA Vieira,ACC Oliveira,IC Oliveira 展开 摘要: A simple method for fabrication of bismuth nanoparticles from bulk bismuth by a microwave irradiation is reported. Bismuth nanoparticles of near spherical shape have been characterized by atomic force microscopy (AFM) and transmission el...
W is prone to oxidation resulting in instantaneous sublimation of volatile W oxides. Herein, we present a detailed in-situ XRD analysis of the morphological changes of a 3-layer-system: HfO2/W/HfO2layers, in a high-temperature environment, up to 1520 °C. These samples were annealed between...

Raman analysisProcessing of graphite from its ore has been studied for more than a decade due to the elevated demand for graphite which has a wide range of applications but restricted to the short availability of resources. In the present study, microwave irradiation was used for the ...
However, other research have shown that W-H underestimates by ±14% the particle size as compared to Scherrer, of which the correlation was confirmed with TEM [3]. The Williamson-Hall (W-H) method for crystallite size and strain analysis is still under-utilized as compared to the Scherer ...
Application of X-ray Diffraction Methods and Molecular Mechanics Simulations to Structure Determination and Cotton Fiber Analysis The results of three very different studies are presented. X-ray diffraction has been utilized for single-crystal structure determinations, fiber diffracti... Z Moore 被引量...
