Urinary excretion of aluminium after a successful transplant can reverse pre-transplant aluminium intoxication. We have evaluated the time course of urinary aluminium excretion and its correlation with several parameters of renal function and mineral metabolism in 49 patients (33 men and 16 women) with a wide range of pre-transplant serum aluminium concentrations, performing sequential determin...

Mechanical alloying has recently attracted considerable attention as researchers strive to enhance nanocomposite properties and extend their utility. The process can be performed at room temperature and homogeneous nanocomposite powders can be produced. In this paper, we investigated the effect of different ball milling parameters and operating conditions (milling time, ball size, processing co...

Ceria-based gold catalysts were successfully deposited on ferritic stainless steel (Fecralloy) and aluminium monoliths. The prepared monolithic and reference powder catalysts were characterized by means of SBET, X-ray diffraction, glow discharge optical emission spectroscopy and scanning electron microscopy–energy dispersive X-ray analysis techniques and tested in the CO oxidation reaction. Cha...

A new epoxy-resin-based optical phantom system with adjustable subdiffusive scattering parameters is presented along with measurements of the intrinsic absorption, scattering, fluorescence, and refractive index of the matrix material. Both an aluminium oxide powder and a titanium dioxide dispersion were used as scattering agents and we present measurements of their scattering and reduced scatte...

Aluminum metal foam has become an advanced popular material because it excellent mechanical and electrical properties is lightweight. The present work developed the Aluminium specimen using wax powder as a blowing agent through metallurgy method. effect of process parameters such size, stirring speed, sintering temperature, foaming content on behavior specimens been studied experimentally. In d...

High-aluminium steels contain a significant amount of aluminium. The reaction between Al in the liquid steel and SiO2 lime-silica-based mould powders during continuous casting process high causes chemical compositional changes powders, subsequently affecting surface quality slabs. In order to solve aforementioned problem, lime-alumina-based have been developed, which can lead an increase cast s...

Horse spleen ferritin was found to bind aluminium poorly after equilibrium dialysis with buffered aluminium citrate solutions. Not more than 10 aluminium atoms/ferritin molecule were bound from a 25 microM-aluminium solution, pH 7.4, and the degree of binding was dependent on the method used to prepare the aluminium citrate solution. Up to 120 aluminium atoms/molecule were bound when ferritin i...

Aluminium balance studies were carried out on eight patients with various immunological disorders who were receiving plasma exchange with albumin solutions known to be contaminated with aluminium. Four patients with impaired renal function (creatinine clearance less than 50 ml/min) retained between 60% and 74% of the aluminium infused during a single plasma exchange. Transiliac bone biopsy spec...

It is of burgeoning importance that the human body burden of aluminium is understood and is measured. There are surprisingly few data to describe human excretion of systemic aluminium and almost no reliable data which relate to aluminium in sweat. We have measured the aluminium content of sweat in 20 healthy volunteers following mild exercise. The concentration of aluminium ranged from 329 to 5...

In situ reaction was activated in the powder mixture of Al/5 wt.%Fe2O3 by using selective laser melting (SLM) to directly fabricate aluminium metal matrix composite parts. The microstructural characteristics of these in situ consolidated parts through SLM were investigated under the influence of thick powder bed, 75  μm layer thickness, and 50  μm layer thickness in various laser powers and sca...
