In this study, the least square method is applied to study the laminar flow, heat transfer and microrotation of MgO-Ag/water micropolar hybrid nanofluid in a permeable channel. The bottom wall is hot and coolant fluid is injected into the channel from the top wall. The base fluid in the channel is water and volume fraction of nanoparticle (50% Ag and 50% MgO by volume) is between 0 and 0.02. By...

This research discusses the development of magnetic materials as an effort to produce renewable catalysts in overcoming energy crisis. The purpose this study was synthesize and characterize MgO/CoFe2O4 nanoparticles using coprecipitation method. synergy between substances that are catalysts, namely MgO CoFe2O4 expected a superior catalyst for biodiesel production. stages were by continued with ...

Various nanoparticles have been developed for bio-applications. However, nanocomposites particles, (NCPs) with effective and ability to sensing cholesterol, are still needed. Herein, we present new cholesterol pH-responsive NCPs as sensor particles promote sensitivity. The traditional method of mixing grinding was used fabricate the oxides magnesium manganese MgO–MnO2 different ratios. Structur...

The photochemical growth of silver nanoparticles on the negative domains of lead zirconate titanate thin films is reported. A sample of highly [100] orientated lead zirconate titanate, with a ratio of 30:70, that was 65-70 nm thick grown on Pt-coated MgO was poled by use of piezoresponse force microscopy to produce defined regions of surface positive and negative polarization. A comparison betw...

The conventional liquids have some limitations regarding the thermal properties. The nanoparticles addition is one of the techniques which can modify them. In this research, heat transfer coefficient (h) and pressure loss (Δp) of various nanofluids containing Al2O3, SiO2 and MgO nanoparticles dispersed in water in an annular tube with constant wall temperature were numerically considered. Accor...

Methylglyoxal (MGO) is a reactive metabolite of glucose. Since the plasma concentration of MGO is increased in diabetic patients, MGO is implicated in diabetes-associated vascular endothelial cells (ECs) injury, which might be responsible for atherosclerosis. In the present study, we examined effects of treatment of human umbilical vein ECs with MGO on EC morphology and inflammatory responses. ...

Methylglyoxal (MGO)-induced carbonyl stress and pro-inflammatory responses have been suggested to contribute to endothelial dysfunction. Curcumin (Cur), a polyphenolic compound from Curcuma longa L., may protect endothelial cells against carbonyl stress-induced damage by trapping dicarbonyl compounds such as MGO. However, Cur-MGO adducts have not been studied in depth to date and it remains to ...

The current work focuses on the preparation of magnesium oxide nanoparticles using aqueous chloride salts and sodium hydroxide powder by a simple chemical precipitation method at an annealing temperature 700 °C for 6 hours. structural morphological properties were investigated X-ray diffraction (XRD). Polycrystalline cube Scherer equation showed crystalline size 17.23 nm. EDS analyzes high puri...
