This study investigates the wear performance of Hybrid composite Aluminium Al 7075 (SiC/Al2O3). The Reinforcements used for preparation are Silicon Carbide (SiC) and Oxide (Al2O3). added in 5%, 10% 15% volume percentage to aluminium alloy preparation. developed composites was analysed using dry sliding test apparatus. effect parameters such as load, distance, velocity on response rate were pred...

Investigation of aluminium uptake by human erythrocytes was the major aim of this study. Packed red blood cells were incubated in Earle's medium (pH 7.4) containing varying concentrations of aluminium (0-160 /lg/J) as AIK(SO.), and aluminium content of the cells were determined using flameless atomic absorption. There was significant increase in aluminium content of the cells. Addition of 5...

Impurities enter the electrolyte mainly from the consumable carbon anode and aluminium oxide. Important impurity elements are iron, silicon, phosphorus and sulfur. Metallic impurities such as iron and silicon tend to codeposit at the cathode, while dissolved phosphorus and sulfur species also affect the current efficiency for aluminium production. In modern industrial cells more impurities end ...

A highly self-ordered hexagonal array of cylindrical pores has been fabricated by anodizing a thin film of Al on substrate and subsequent growth of GaN and InGaN in these nanoholes has been performed. This AAO templatebased synthesis method provides a low cost process to fabricate GaN-based nanomaterials fabrication.

Aluminium (Al) toxicity is closely linked to the pathogenesis of Alzheimer's disease (AD). This experimental study investigated the neuroprotective effect of melatonin (Mel; 10 mg/kg bwt) on aluminium chloride (AlCl3 ; 34 mg/kg bwt) induced neurotoxicity and oxidative stress in rats. Adult male albino Wistar rats were injected with AlCl3 for 7 days. The effect on brain structure, lipid peroxida...

Abstract The high use of aluminium foil in food and beverage packaging has caused solid waste to increase rapidly, so treatment is required. This study investigates the best concentration reactant recovery from as potash alum coagulant. Potassium hydroxide used for dissolved aluminium, sulphuric acid added form crystals. experimental result got a maximum point synthesis foil: potassium 3 M dan ...

A study of reflective interference spectroscopy [RIfS] properties of nanoporous anodic aluminium oxide [AAO] with the aim to develop a reliable substrate for label-free optical biosensing is presented. The influence of structural parameters of AAO including pore diameters, inter-pore distance, pore length, and surface modification by deposition of Au, Ag, Cr, Pt, Ni, and TiO2 on the RIfS signal...
