The static linear and nonlinear optical properties of (ZnO)N clusters N= 2–12 are studied using finite field approach within the framework density functional theory. Most these feature ring or cage structures in specific size range, differing much from wurtzite structure bulk ZnO. low-lying isomers with various possess remarkably different properties. effect structure, cluster stability, HOMO–LUMO gap, covalent/ionic bonding, etc., on dipole moment, polarizability, first second...
The electrical stability of transparent conductive oxides is an important criterion for evaluating their performance, especially when they are employed at elevated temperatures or in long-term operation. In this work, indium-doped ZnO thin films with various doping concentrations were prepared by RF sputtering. properties, thermal stability, and time differing indium contents investigated. results showed that the degradation films' conductivity primarily attributable to reduction oxygen...
Bandgap engineering and shape control are important advantageous for potential applications involving colloidal ZnO nanocrystals. Here we demonstrate the syntheses of high quality alloyed CdxZn1−xO nanocrystals with well-defined shapes, from faceted particles to tetrapods ultrathin nanowires. By comparing optical bandgaps pure ZnO, MgxZn1−xO various dimensions, conclude that bandgap via cadmium alloying effectively narrows bandgaps. Our study may shed light on design oxide controlled band...
The behaviors of and mechanisms acting in Ti-6Al-4V alloy during low-temperature superplastic deformation were systematically studied by using a Gleeble-3800 thermocompression simulation machine. Focusing on the mechanical microstructure evolution laws compression tests, we clarified changing strain rate sensitivity index, activation energy deformation, grain index at varying rates temperatures. Hot working images based dynamic material model mechanism maps involving dislocation quantity...
In this work, Ga-doped ZnO (GZO) thin films were deposited via radio frequency sputtering at room temperature. The influence of the Ga content on film’s optoelectronic properties as well electrical stability investigated. results showed that crystallinity degraded with increasing content. conductivity was first enhanced due to replacement Zn2+ by Ga3+ before decreasing separation neutralized gallium atoms from lattice. When increased 15.52 %, improved again. Furthermore, all presented an...
Abstract Traditional preparation of ZnO nanocrystal requires heating zinc acetate to a temperature over 350 °C, whereas in this work, was first electrospun with PVDF form nanofiber, followed by thermal treatment at only 140 °C give nanocrystalline ZnO. The much lower required is attributed the high reactivity nano dimension. as-prepared ZnO-doped nanofiber mat shows excellent effect photocatalytic degradation Rhodamine B, comparable particle thermally treated 600 °C. Highly-oriented nanorods...
A phase stability diagram of ruthenium-zirconium oxide (Ru-Sn-O) was constructed by a combination ab initio density functional theory and thermodynamic calculations. Results suggest that the separation/segregation has been reported in literature for RuO(2)-SnO(2) system is through typical spinodal decomposition mechanism. Ru(0.45)Sn(0.55)O(2) films were prepared thermal co-decomposition precursors at 500 °C varied duration. Quantitative analyses based on X-ray diffraction high-resolution...

In this work, p-type non-stoichiometric Ni1−xO thin films were deposited by oxygen ion beam assisted RF sputtering on glass substrates. The influence of the flow ratio (0–100%) films’ optoelectronic properties was investigated. our experimental conditions, all are crystallized in cubic NiO phase. However, their crystallinity and mean grain size decreases with increasing ratios. Meanwhile, conductivity improves from 9.1 to 25.4 S·cm−1. This is due fact that nickel vacancies along hole...
Fine-grained Ti-6Al-4V titanium alloy plates were manufactured using a direct rolling approach, and series of superplastic tensile tests conducted at varying temperatures strain rates. The maximum elongation 816% was obtained 810 °C 5 × 10−4 s−1, the flow behavior dominated by strain-induced grain boundary slip. In addition, behaviors investigated, α-and β-phase Gibbs free energy calculated. vital role phase β in transformation discussed from thermodynamical perspective. A power dissipation...
