This paper deals with the dynamic response of Functionally Graded Material (FGM) plates resting on a viscoelastic foundation under loads. The governing equations are derived by using Hamilton’s principle classical plate theory and higher-order shear deformation theory. Using state-space methods to find closed-form solution functionally graded rectangular foundation. Numerical examples given for displacement stresses in various structural parameters effects these discussed. result numerical...
The photocatalytic activity of p-Si/p-CuO buffer layer/n-ZnO nanorod (NR) composite films was studied using experimental and simulation methods. results indicated that in the p-Si/p-CuO/n-ZnO film, 250 nm CuO layer contributes highest value 11% to total current density compared p-Si/n-ZnO film. Besides that, also by introducing p-CuO layer, pseudo-order rate constant (k) could be enhanced up 12% film without - Furthermore, recycle result k decreased sharply after first three reaction cycle...
Harvest residues can play a crucial role in conserving nutrients for recycling forests, but little is known about the rates of decomposition and nutrient release from these following logging tropical acacia plantations. In this study, we examined biomass content harvest residue components (bark, leaves, branches) using litterbag technique 1.5-year-period seven-year-old Acacia mangium plantation Northern Vietnam. At harvest, total dry was 18 t ha−1 comprising bark (8.9 ha−1), branches (6.6...
This paper is to investigate the optimization of mechanical properties for maximum tensile strength, elongation, and impact strength Polycarbonate Polymethyl methacrylate (PC/PMMA) blends by injection molding process. The PC/PMMA plastics composites with different blending percentage are first blended have been injected as specimens designed according ASTM, type V machine. Taguchi’s method then used find optimal parameters elongation strength. control factors selected in this study melt...
In this paper, the displacement variation in sandwich beams is determined by employing a semi-analytical approach. The classical calculated integration using Mohr’s equation, although complicated due to inclusion of random fields inertial moment term. Using trapezoidal rule compute these integrals, are discretized into variables at nodal point beam segments. Thus, expected displacement, standard deviation, and coefficient can be computed. To validate results, simulated previously described...
CuO:ZnO nanocomposite photocatalyst with tunable ratios of CuO was synthesized using a low-temperature-assisted co-precipitation method, which is suitable for industrial-scale production. Analytical techniques, including XRD, FE-SEM, HR-TEM, FTIR, XPS and UV–Vis, were utilized to investigate the structure, morphological characteristics, chemical composition optical properties nanocomposite. The XRD analysis reveals that samples exhibit single phase, characterized by wurtzite hexagonal...
The ZnO:CuO nanocomposite photocatalytic activity was experimentally and numerically investigated. This exhibits stability durability during photodegradation. with a ZnO/CuO ratio of 2.0 synthesized by microwave-assisted hydrothermal at 70 °C in 10 minutes photocurrent density over 1.0 mA.cm−2 for the ZnO layer an optimal degradation efficiency 86.4 %. efficacy depends on current generated rather than total photo-induced current. can be promising photocatalyst because its enhanced light...
NaYF4:(Yb,Tm) upconversion materials were synthesized by the simple hydrothermal method. Growth duration was varied from 4h to 12h under a growth temperature of 150oC. The structural, optical and surface morphology characteristics UC investigated. XRD SEM results illustrated that transformed multiple phases (hexagonal cubic) single-phase prism) as being longer than 8h with average diameter length these prisms about 0.5 µm 2 µm, respectively. Under 980 nm laser excitation, emits at peaks 450...
