Uncertainties exist over the glomerular filtration of aluminium and virtually nothing is known about its segmental handling along the nephron. The present study has used micropuncture, combined with electrothermal atomic absorption spectroscopy, to determine directly the aluminium content of glomerular filtrate and of late PCTs (proximal convoluted tubules) and early distal tubules in anaesthet...

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...

Aluminum nitride (AlN) is considered one of the most desirable materials for integrated circuits and electronic packaging substrates. However, raw AlN powder reacts easily with water, forming Al(OH)3 or AlOOH on surface hindering development aqueous tape casting process preparing ceramic In this study, hydrolyzed polymaleic anhydride (HPMA) was used to modify powder, which has good w...

Several different ways of measuring the energy resolution for meV-resolved inelastic X-ray scattering (IXS) are compared: using from poly(methyl methacrylate), PMMA, borosilicate glass (Tempax), and powder diffraction aluminium. All these methods provide a reasonable first approximation to resolution, but, also, in all cases, contributions appear over some range transfers. Over ±15 meV transfer...

Until 1990 biokinetic studies of aluminium metabolism and biokinetics in man and other animals had been substantially inhibited by analytical and practical difficulties. Of these, the most important are the difficulties in differentiating between administered aluminium and endogenous aluminium-especially in body fluids and excreta and the problems associated with the contamination of samples wi...
