An automated method to determine the band gap energy (Eg) of pure and mixed powder compounds using diffuse reflectance spectroscopy is presented. This based on a five-step algorithm that mimics judgment made by an expert analyst in identifying linear segments Tauc plots subsequent estimation Eg value. It demonstrated estimate intersecting straight-line fit segment with photon axis not appropriate for those samples containing more than one optical absorbing phase because systematic...
Abstract The effect of chemical order in the structural and physicochemical properties B 12 N [4,6]-fullerene (BNF) isomers was evaluated using density functional theory molecular dynamic calculations. feasibility to find stable BNF with atomic arrangement other than well-known octahedral T h -symmetry explored. In this study, number homonuclear bonds modeled nanostructures used as categorical parameter describe quantify degree order. without identified most energetically favorable isomer....
One dimensional zinc oxide nanostructures were grown by a low temperature hydrothermal process. Effects of Ga doping on the growth, crystallization, and defect distribution in them studied x-ray diffraction, scanning electron microscopy, photoluminescence, Fourier-transform infrared spectroscopy techniques. It has been shown that improves morphological homogeneity optical properties ZnO nanostructures. Improved morphology doped have associated with catalytic effect Ga. quenching emission...
ZnO nanostructures with triangular and rod-like morphologies could be grown by thermolysis of zinc acetate in oleylamine solvent using oleic acid as surfactant. Concentration the precursor reaction mixture had a strong effect on final morphology nanostructures. While low concentration results morphology, high concentrations favor The room temperature photoluminescence (PL) spectra both are dominated green emission attributed to oxygen vacancy (VO) related donor−acceptor transition. Presence...
Abstract The effect of carbon doping on the structural and physicochemical properties B 12 N 12‐ x C [4, 6]‐fullerenes (0 ≤ 6) (BNFs) is studied in frame density functional theory. All non‐symmetry related isomers are modeled. Although reduces cohesive energy BNFs, most them remain stable. It found that location atoms lowest‐energy follows a definite sequence as level increases. results indicate substitutional lowers gap chemical hardness but it increases their electronegativity...
Six organic compounds derived from 2-amino-5-alkylthiadiazole were evaluated as corrosion inhibitors of carbon steel 1018 (CS 1018) in 1.0 M H2SO4. The inhibition efficiency displayed by the synthesized was assessed mass loss, using a concentration interval 10-100 ppm at 25 and 40 °C. potentiodynamic tests carried out only with that showed lowest [AMT], intermediate [AHT] highest [ATT] efficiencies obtained loss. results both techniques length alkylic chain this kind plays major role their...
A method for obtaining nanosized LaCoO 3 crystals from calcination of a precursor powder synthesized by hydrothermal route is reported. Details concerning the evolution microstructure and formation mechanism perovskite phase were studied X-ray diffraction, scanning electron microscopy, energy dispersive spectroscopy, Raman thermal analysis. It was found that morphology sample progressively turns mix fibers rods to interconnected nanocrystals. determined produced reaction cobalt lanthanum...
The characterization of the structural, electronic, and magnetic properties octagraphene-like boron-nitride: BN (B32N32H24, B37N27H24, B27N37H24), nanosheets were performed by means density functional theory all-electron calculations at HSEh1PBE/GGA level. Orbital 6–311G(d,p) basis sets used. Non-stoichiometric B37N27H24 B27N37H24 compositions: rich in boron or nitrogen atoms, forming homonuclear B N bonds, respectively, chosen. obtained results reveal that these reach structural stability...
Abstract BiOI nanostructures were synthetized through a hydrothermal process using either bismuth acetate or subsalicylate as Bi precursor. Regardless of the used source, same crystalline structure was obtained; nevertheless, nature precursor had an evident impact in color appearance obtained sample. Another notable difference observed resulting morphology, where ∼1.6 μ m flower- and dandelion-like shapes for subsalicylate, respectively; both structures assembled by around 30 nm thick...
