Gold exploration with portable X-ray diffraction (pXRD)
WebOur SEM and TEM studies show that gold coated nanoparticles with Fe core are formed (a core/shell structure) with a size distribution from few tens nanometers. The as-prepared nanoparticles show Fe/Au with a spherical- shape and an average size of 71 nm. X-ray diffraction was applied to confirm the phase of the core material. WebApr 14, 2024 · Abstract. This investigation reports an eco-friendly fabrication of cerium vanadate nanoparticles (CeVO 4 NPs) for the first time by an utterly green approach using Azadirachta indica leaves extract as a natural fuel. Textural properties of the as-prepared CeVO 4 NPs, such as structural, topological, and optical, were explored through X-ray … WebWe have prepared the gold nanoparticles by adding different amounts (200, 240, 280, 320, 360, and 400 μl) of 1 wt.% trisodium citrate solution to 50 ml of 0.01 wt.% chlorauric acid solution while heating to boiling. Figure 1 illustrates a typical XRD pattern of the gold nanoparticles obtained from the solution with 400 μl of trisodium citrate. how were women portrayed in the 1950s media
