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...
The pilot production ecosystem deployed by the EU-project OASIS consists of 12 lines (PLs) for manufacture nanomaterials, nano-intermediates and nano-enabled products, intended final lightweight multifunctional based on aluminium polymer composites, construction, energy, automotive aeronautics. intends to deploy this nanomanufacturing under a common umbrella sustainable production, ensure futur...
nano-sized γ-al2o3 was synthesized successfully by a simple method using al2(so4)3·18h2o as aluminium source and in the presence of polyethylene glycol (peg 2000). ftir spectroscopy, x-ray diffraction (xrd), scanning electron microscope (sem) and transmission electron microscope (tem) were used to characterize the structure and morphology of synthesized powder. the results showed that peg playe...
The effects of aluminium and aluminium-citrate on some serum parameters related to carbohydrate metabolism in male Wistar rats were investigated. Daily intraperitoneal administrations of 1 mg/kg body weight of aluminium or aluminiumcitrate (1: 1) for 50 days led to the elevation of serum insulin by 24 or 40 percent respectively, with the concomitant decrease in serum glucose concentrations ...
Aluminium alloys such as AA2024 are susceptible to severe corrosion attack in aggressive solutions (e.g. chlorides). Conversion coatings, like chromate, or rare earth conversion coatings are usually applied in order to improve corrosion behaviour of aluminium alloys. Methacrylate-based hybrid films deposited with sol–gel technique might be an alternative to conversion coatings. Barrier properti...
alumina is one of the most widely used ceramic materials as catalysts, catalyst supports and absorbents, and also wear resistant coating. this study focused on fabricating and characterizing of alumina ceramic nanoparticles fabricated using new and simple sol-gel method. aluminium oxide (al2o3) nanoparticles were synthesized by iron (iii) nitrate 9-hydrate as precursor. physicochemical properti...
Aluminium (Al) has been investigated as a neurotoxic substance. Al ranks among the potential environmental risk factors for Alzheimer's disease (AD). Epidemiological studies tested the relationship between Al in drinking water and AD, showing a significant correlation between elevated levels of monomeric Al in water and AD, although data to date remain inconclusive with respect to total Al. The...
