In this study, different nanofluids with phase change behavior were developed by mixing a molten salt base fluid (selected as material) nanoparticles using the direct-synthesis method. The thermal properties of obtained investigated. These can be used in concentrating solar plants reduction storage material if an improvement specific heat is achieved. mixture was NaNO3-KNO3 (60:40 ratio) binary salt. silica (SiO2), alumina (Al2O3), titania (TiO2), and mix silica-alumina (SiO2-Al2O3).

In this study different nanofluids with phase change behavior were developed by mixing a molten salt base fluid (KNO3 selected as material) nanoparticles using the direct synthesis method. The thermal properties of obtained investigated. Following improvement in specific heat achieved, these can be used concentrating solar plants reduction storage material. (1.0 wt.%) silica (SiO2), alumina (Al2O3), and mix silica-alumina (SiO2-Al2O3) an average diameter 7, 13, 2–200 nm respectively. Each...
Abstract The aim of this study was to investigate the mechanical behavior a dental system built up with fiber‐reinforced composite (FRC) endodontic posts different types fibers and two cements (the first one used primer, second without it). Six FRC were used. Each characterized in terms structural efficiency under external applied loads similar masticatory forces. An oblique force stiffness maximum load data obtained. same test for dentine. systems analyzed by scanning electron microscope...
High temperature solar cooking allows to cook food fast and with good efficiency. An unavoidable drawback of this technology is that it requires nearly clear-sky conditions. In addition, evening difficult be accomplished, particularly on the winter season during which radiation availability limited a few hours in afternoon most countries. These restrictions could overcome using cooker thermal storage unit (TSU). work, TSU based salt was studied. The consists two metal concentric cylindrical...
The inflammatory resorption of dental root apex (i.e., the process removal cementum and/or dentine through activity resorbing cells) may show different configurations and damage apical structure. As knowing morphology areas human teeth is essential for success endodontic treatments, we investigated by scanning electron microscopy, focusing on roots with granulomas. A total 30 (with penetrating carious lesions chronic periapical lesions) were examined, third removed analyzed to estimate...
In this study, different nanofluids (NFs) were developed by mixing a molten salt mixture (60% NaNO3–40% KNO3) with 1.0 wt % of silica–alumina nanoparticles using methods. These NFs can be used as thermal energy storage materials in concentrating solar plants reduction material if the properties base fluid are increased. New procedures without sonication introduced aim to avoid step and allow production greater amount NF procedure potentially more suitable for large-scale productions. For...
The effect of etching on cat enamel made with 40% orthophosphoric acid for different times was evaluated. Twenty‐one teeth were selected and randomly divided into three groups seven each. They subjected to a circular area the coronal (diameter = 2 mm) 30 s (group A), 45 B) 60 C). samples obtained observed by scanning electron microscope focusing border between etched unetched enamel, highlight differences. micrographs blind assessment experienced operators. statistically assessed Wilcoxon...
