Fabrication of suitable roughness is a fundamental step for acquiring superhydrophobic surfaces. For this purpose, a deposition of ZnO nanoparticles on Al surface was carried out by simple immersion and ultrasound approaches. Then, surface energy reduction was performed using stearic acid (STA) ethanol solution for both methods. The results demonstrated that ultrasound would lead to more stable...

Conventional water and wastewater treatment methods Nanoparticles (NPs) from anthropogenic sources have applications in several commercial products, including cosmetics, pharmaceuticals, and materials. There is evidence that during their usage and disposal, engineered nanoparticles can andwill be released into wastewater (Gottschalk et al., 2013; Pasricha et al., 2012; Westerhoff et al., 2013; ...

Grinding is finishing process aimed at achieving surface quality and dimensional accuracy in workpieces with tight tolerances especially from materials with a high degree of hardness and strength. The grinding process of superalloys is faced with problems and challenges caused by the generation of excessiveheatas well as the adhesion of workpiecematerialon the grinding tool. Therefore, in-depth...

A new method to fit experimental diffraction data with non-periodic structure models for spherical particles was implemented in the reverse Monte Carlo simulation code. The method was tested on x-ray diffraction data for ruthenium (Ru) nanoparticles approximately 5.6 nm in diameter. It was found that the atomic ordering in the ruthenium nanoparticles is quite distorted, barely resembling the he...

Abstract This study investigated the effects of adding titanium dioxide (TiO 2 ) and aluminium oxide (Al O 3 nanoparticles into Sn3.0Ag0.5Cu (SAC) lead-free solder alloy on thermal properties wettability. In comparison with SAC without addition nanoparticles, melting temperature is very similar comparable. The solidus in range 217.1 to 217.2 °C TiO Al nanoparticles. results shows that 0.25-1.0 ...
