TL;DR: In this article, the effect of generalized Reynolds numbers on the main vortex characteristics and Couette correction was examined in detail in the range varying from 0.01 Regen 600 to 0.3.
Abstract: The laminar flow of inelastic non-Newtonian fluids, obeying the power-law model, through a planar sudden expansion with a 1:3 expansion ratio was investigated numerically using a finite volume method. A broad range of power-law indices in the range 0.2 n 4 was considered. Shear-thinning, Newtonian and shear-thickening fluids are analyzed, with particular emphasis on the flow patterns and bifurcation phenomenon occurring at high Reynolds number laminar flows. The effect of the generalized Reynolds numbers (based on power-law index, n, and the in flow channel height, h) on the main vortex characteristics and Couette correction are examined in detail in the range varying from 0.01 Regen 600. Values for the critical generalized Reynolds number for the onset of steady flow asymmetry and the appearance of a third main vortex are also included. We found that the shear-thinning behavior increases the critical Regen, while shear-thickening has the opposite effect. Comparison with available literature and with predictions using a commercial software (FluentR 6.3.26) are also presented and discussed. It was found that both results are in good agreement, but that our code is able to achieve converged solution for a broader range of flow conditions, providing new benchmark quality data.

TL;DR: In this paper, a facile and effective ultrasonication assisted approach has been employed to integrate hydrothermally produced CuO microspheres (CMS) with chemically synthesized reduced graphene oxide conducting nanosheets (CRGO), yielding a new composite material (CSCO).
Abstract: Herein, a facile and effective ultrasonication assisted approach has been employed to integrate hydrothermally produced CuO microspheres (CMS) with chemically synthesized reduced graphene oxide conducting nanosheets (CRGO), yielding a new composite material (CSCO). The synthesized materials have been probed by various characterization techniques. The electrochemical performance of all the materials are thoroughly studied by cyclic voltammetry (CV), galvanostatic charging-discharging (GCD) and electrochemical impedance spectroscopy (EIS) techniques. At a current density of 0.125 A g−1, CSCO demonstrates an excellent specific capacitance of 244 F g−1 (more than six times higher than CMS and CRGO) and the maximum energy and power density values of 8.47 Wh kg−1 and 73.49 W kg−1, respectively. Additionally, it exhibits high rate performance (retains 82.78 % of its initial capacitance even at a high current density of 0.5 A g−1) and long cycle life (∼ 90 % up to 1000 cycles), confirming the robustness and high stability of the composite on the electrode surface. The superior electrochemical performance can be attributed to the positive synergistic effects between CMS and CRGO, providing mechanical robustness and short diffusion path for charge transfer, leading to high conductivity. Distinguishing features such as being binder-free, ease of preparation, high energy and power density, make CSCO a potential candidate for high performance supercapacitors.

TL;DR: In this paper, the structural, optical and electronic structure of Fe doped LaGaO3 have been investigated and it is observed that with Fe doping the lattice parameter of the prepared samples systematically increases whereas the optical band gap decreases.
Abstract: A polycrystalline sample of LaGa1−xFexO3 has been prepared by solid state reaction. The structural, optical and electronic structure of Fe doped LaGaO3 have been investigated. It is observed that with Fe doping the lattice parameter of the prepared samples systematically increases whereas the optical band gap decreases. First-principles density functional theory (DFT) calculations were carried out to understand the effect of Fe doping on the electronic structure and to understand the origin of systematic decrease in optical band gap. DFT studies suggests that there exists an indirect band gap to direct band gap transition with Fe doping which is further confirmed using photoluminescence measurements. Photoluminescence studies suggest that Fe doped LaGaO3 are potential candidates as white light emitting materials.
