Due to the lack coupling analysis of heavy metals in soil-plant-atmosphere system, migration and transformation remains unclear. In this study, 240 surface (0–20 cm) soil samples, 365 plant samples 168 atmospheric dust were collected a large coal mining area, which selected arsenic (As), cadmium (Cd), chromium (Cr), copper (Cu), nickel (Ni), plumbum (Pb), zinc (Zn) analyzed, elucidate spatial distribution source their bioavailability. According results ArcGIS mapping analysis, patterns Cd,...
In this paper, BPO4 and Ba2+-doped powder samples were prepared by the sol−gel process using glycerol poly(ethylene glycol) as additives. The structure optical properties of resulting characterized X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy, field emission scanning electron microscopy (FESEM), diffuse reflection spectra, photoluminescence (PL) excitation quantum yield, kinetic decay, paramagnetic resonance (EPR), respectively. It was found that undoped showed a...
ZnO and ZnO:Zn powder phosphors were prepared by the polyol-method followed annealing in air reducing gas, respectively. The samples characterized X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM), photoelectron spectra (XPS), paramagnetic resonance (EPR), photoluminescence (PL) cathodoluminescence (CL) spectra, results indicate that all are agreement with hexagonal structure of phase particle sizes range 1-2 microm. PL CL powders annealed at 950 degrees C consist...
Abstract An overview of the electrodeposition ZnO nanowire arrays from reduction dissolved molecular oxygen in zinc chloride solutions was reported. In spite internal structure which favours anisotropic growth along [0001] direction, change local composition electrolyte around during proposed as a major parameter to affect mechanism. The influence ratio between O 2 rate and diffusion Zn 2+ cathode emphasized. Due particular morphology arrays, no lateral observed when relatively fast, while...
white/red/green phosphors were prepared by the Pechini sol-gel process. X-ray diffraction (XRD), field-emission scanning electron microscopy (FE-SEM), diffuse reflectance, photoluminescence, cathodoluminescence spectra, and lifetimes utilized to characterize samples. XRD reveal that samples begin crystallize at pure phase can be obtained . FE-SEM images indicate , consist of fine spherical grains with size around Under excitation ultraviolet light low-voltage beams show characteristic...
Introduction of photoactive perylenediimides into the self-directed supramolecular silsesquioxane systems gives superlong tubular structure with length several hundred micrometers and diameters ranging from 1 to 9 μm as determined by FE-SEM. XRD demonstrated that wall tubes arranged in lamellar structure. A mechanism has been proposed for formation tubes. The effects closely packed on its optical behaviors are UV−vis absorption photoluminescence spectra.
The low-pressure distillation of FLiBe salt containing ThF4 was carried out at 1223 K and <10 Pa using thermogravimetric equipment. weight loss curve indicated a rapid stage the beginning distillation, followed by slow stage. composition structure analyses showed that process originated from evaporation LiF BeF2, while mainly attributed to complexes. Precipitation-distillation coupled method employed for recovery carrier salt. XRD analysis ThO2 formed remained in residue with addition BeO....
The electrochemical behavior of UO2F2 in LiF-NaF-KF (46.5-11.5-42 mol%, FLiNaK) melt on Pt electrode was investigated at 550°C by cyclic voltammetry (CV) and square wave (SWV). prepared the reaction UF4 powder oxygen 650°C, ascertained X-ray diffraction (XRD) Raman spectroscopy. It found that reduction UO22+ FLiNaK exhibited two steps both with one exchanged electron: + e− → UO2+ UO2, CV peak about 2.02 V 1.49 (vs. K+/K), respectively. Both them were reversible diffusion-controlled. By means...
Monodisperse, core-shell-structured particles were prepared by the sol-gel method. The samples characterized X-ray diffraction, field emission scanning electron microscopy, transmission photoluminescence (PL), and low-voltage cathodoluminescence (CL) as well time-resolved PL spectra lifetimes. CL study revealed that show strong red dominated transition of at with a lifetime . intensity can be tuned coating number phosphor layers on accelerating voltage filament current, respectively.
