As a special type of aviation hydraulic pipe joint, a beam seal comprises two annular sealing areas.This paper presented a silicone-toys leakage model for an annular sealing area based on a developed three-dimensional percolation grid model and the porous medium theory.Both average contact pressure and true contact width of the beam seal were simul
The concentrations of inorganic elements in soils of Saje, Ita-Oshin, Premier, and Oke-Diya dumpsites were determined using an X-Ray Fluorescence spectrometer to assess the soil quality through chronological changes with depths.A soil core sampler collects 56 samples at 20, 40, 60, and 80 cm depths.Saje showed high mean concentrations of Ca, K, Fe,
Photocatalysis is gaining prominence as a viable alternative to conventional biohazard treatment technologies.Two-dimensional (2D) nanomaterials have become crucial for fabricating novel photocatalysts due to their nanosheet architectures, large surface areas, and remarkable physicochemical properties.Furthermore, a variety of applications are poss
This paper reports the comprehensive characterization of a Ge0.92Sn0.08/Ge0.86Sn0.14/Ge0.92Sn0.08 single quantum well.By using a strain relaxed Ge0.92Sn0.08 buffer, the direct bandgap Ge0.86Sn0.14 QW was Barware achieved, which is unattainable by using only a Ge buffer.Band structure calculations and Ironing Stations optical transition analysis rev
