In this research, Cr2O3 ceramic nano-sized powder particles were prepared using ball milling and then granulated to reach the proper size for spraying. Afterward, nano-coatings deposited by atmospheric plasma spraying (APS) process onto stainless steel substrates. To optimize APS parameters, was carried out under six conditions with different parameters. Microstructures of elemental/milled coat...

BACKGROUND There is a global need for cost-effective and environmentally friendly tools for control of mosquitoes and mosquito-borne diseases. One potential way to achieve this is to combine already available tools to gain synergistic effects to reduce vector mosquito populations. Another possible way to improve mosquito control is to extend the active period of a given control agent, enabling ...

Stabilizers are commonly used to inhibit the ice recrystallization process that leads formation of large crystals, decreasing consumer acceptance cream. However, inhibition (IRI) effect stabilizers is very dependent on measurement conditions. The cause this dependence not clear, which imposes problems in comparing IRI activity and understanding mechanism stabilizers. This study investigated inf...

We prove that the 3-D free-surface incompressible Euler equations with regular initial geometries and velocity fields have solutions which can form a finite-time “splash” (or “splat”) singularity first introduced in [9], wherein the evolving 2-D hypersurface, the moving boundary of the fluid domain, self-intersects at a point (or on surface). Such singularities can occur when the crest of a bre...

Thermal barrier coatings (TBCs) based on Yttria-stabilized Zirconia (YSZ) deposited by the solution precursor plasma spray (SPPS) technique have been claimed to exhibit superior durability compared to conventional plasma spraying and even electron-beam physical vapor deposition. This has been attributed to the interesting features, like vertical cracks, nanosized pores, and fine splats that are...

Alloying anodes such as silicon are of great interest for lithium-ion batteries due to their high storage capacities, but have only seen minimal commercial deployment limited calendar life. This has been attributed an intrinsically unstable solid electrolyte interphase (SEI) that is aggravated by mechanical failure. An amorphous structure can mitigate lithiation strains, and alloys, or metallic...

Microcrystalline and nanocrystalline AlCrFeCoNi high-entropy alloy (HEA) coatings were applied on Inconel 718 superalloy using the atmospheric plasma spraying (APS) process. The high-temperature oxidation behavior of microcrystalline HEA-coated was examined at 1100 °C under air atmosphere for 50 cycles cyclic heating cooling (1 h each cycle). kinetics both nanocrystalline- microcrystalline-coat...

An equiatomic HfNbTaRuZr refractory multi-principal alloy was cast via arc melting and characterized in both as-cast vacuum annealed conditions. (Nb, Ta)-rich body-centered cubic (BCC), (Hf, Ru)-rich B2, Zr)-rich hexagonal close-packed (HCP) phases materials were identified by x-ray diffraction transmission electron microscopy, with all stable from 1350 to 1575 °C. At °C the contained 35.9 % of...

LiDAR sensors provide rich 3D information about their surroundings and are becoming increasingly important for autonomous vehicles tasks such as localization, semantic segmentation, object detection, tracking. Simulation accelerates the testing, validation, deployment of while also reducing cost eliminating risks testing in real-world scenarios. We address problem high-fidelity simulation prese...

The study of flow over various steps behind the hydraulic structures, such as weirs, dams, spillways, barrages, and flood gates, is still particular interest to researchers due complexity characteristics sediment behaviors at near-bed region. This investigates effect inclined backward-facing step (BFS) angles on turbulent structures bedload transport rate in surface jet regime. A combined numer...
