The present review on some metal oxide nanoparticles used for pressure sensor, various metal oxide containing such as (SnO2, ZnO, Al2O3, WO3, Fe2O3, Ga2O3, TiO2 and SiC, ...etc.) responds detection pressure measure in kbar unit through oxygen activity as oxidation or reduction process of an integrated in devices sensor (MEMS, CMOS, MOX and MOXQ1D...etc.) that devices measuring of pressure as st...

This study investigated heat transfer in magnetohydrodynamic (MHD) mixed convection flow of ferrofluid along a vertical channel. The channel with non-uniform wall temperatures was taken in a vertical direction with transverse magnetic field. Water with nanoparticles of magnetite (Fe3O4) was selected as a conventional base fluid. In addition, non-magnetic (Al2O3) aluminium oxide nanoparticles we...

Protein phosphorylation is one of the most studied posttranslational modifications (PTMs) that can regulate cellular processes. Thus, developing appropriate quantitative analysis methods for monitoring the levels of phosphorylated species in a biological system is significant. Isotope labeling quantitative phosphoproteomics has been developed for this purpose. However, isotope labeling reagents...

Using a chemical vapor deposition method with regulated sample temperatures under ambient pressure conditions, we were able to fully decorate the internal structure of a mesoporous Al2O3 bead (~1 mm in particle diameter) with iron oxide nanoparticles (with a mean lateral size of less than 1 nm). The iron oxide-decorated Al2O3 showed a high CO oxidation reactivity, even at room temperature. Very...

In sustainable tribology, researchers are investigating methods to enhance tribological performance by incorporating nanoparticles into lubricants. However, one potential drawback of this strategy is increased lubricant viscosity. The current study aimed assess the impact these on viscosity and coefficient friction (COF) nanolubricants. Three different nanolubricants were synthesized through a ...

Effective control of melting and solidification behaviours of materials is significant for numerous applications. It has been a long-standing challenge to increase the melted zone (MZ) depth while shrinking the heat-affected zone (HAZ) size during local melting and solidification of materials. In this paper, nanoparticle-induced unusual melting and solidification behaviours of metals are report...

This paper investigates the enhancement of heat transfer coefficient and Nusselt number of a nanofluid containing nanoparticles (γ-AL2O3) with a particle size of 20 nm and volume fraction of 0.1%-0.3% (V/V). Effects of temperature and concentration of nanoparticles on Nusselt number changes and heat transfer coefficient in a double pipe heat exchanger with counter turbulent flow are investigate...

Past studies with PTFE nanocomposites showed up to 600× improvements in wear resistance over unfilled PTFE with the addition of Al2O3 nanoparticles. Irregular shaped nanoparticles are used in this study to increase the mechanical entanglement of PTFE fibrils with the filler. The tribological properties of 1, 2, 5 and 10 wt.% filled samples are evaluated under a normal pressure and sliding speed...

In this paper, we study pulsed flow and heat transfer in water-Al2O3 nanofluids in a Y-type intersection channel with two inlets and one outlet. At the two inlets, two sinusoidal velocities with a phase difference of π are applied. We assume that the shear viscosity and the thermal conductivity of the nanofluids depend on the nanoparticles concentration. The motion of the nanoparticles is model...
