The extent of aluminium internalization during the recovery from aluminium stress in living roots of Arabidopsis thaliana was studied by non-invasive in vivo microscopy in real time. Aluminium exposure caused rapid depolarization of the plasma membrane. The extent of depolarization depends on the developmental state of the root cells; it was much more extensive in cells of the distal than in th...

Among the energetic mixtures, one category are thermites. Thermites highly reactive composites described as consisting of a fuel (metal) and an oxidizer (metal oxide) at micron scale. The use nano-sized reactants, with higher surface area to volume ratio than micron-sized counterparts, considerably increases properties consequently raises their interest. present work expands on this aspect by i...

Aluminium is the most abundant metal and constitutes 8% of the earth’s crust. It is a normal constituent of vegetable and animal tissues and is present in raw untreated water. In domestic tap-water supplies, aluminium may be present in high concentrations either from its presence in raw water or, more commonly, as a result of its use during the water-purification process. Aluminium in the metal...

Objective—To investigate possible neurotoxic eVects in groups of aluminium pot room and foundry workers, aluminium welders, and a small group of workers exposed to aluminium in the production of flake powder. Methods—Exposure to aluminium was evaluated with aluminium concentrations in blood and urine as well as a questionnaire. The groups exposed to aluminium were compared with a group of mild ...

The aim of this paper is to focus on the effect of cryogenic treatment on the microstructure, mechanical and wear properties of Al 6061 and Al 8011.  The first objective was to understand the degree to which hardness of these aluminium grades have been enhanced by giving  cryogenic on the specimens. The second objective is to check the wear resistance property of these two aluminium specimens i...

Aluminium, the third most abundant element in the earth’s crust, occurs in nature in combination with silicon and oxygen (i.e. as aluminium silicate). When subject to tropical weathering, aluminium silicate may react to form aluminium hydroxide. Rock containing high concentrations of aluminium hydroxide is called bauxite. This rock is the usual starting material for the production of aluminium....

Blood and urine aluminium concentrations were studied in industrially exposed workers using electrothermal atomic absorption spectrometry. Welders and workers making aluminium powder and aluminium sulphate had higher concentrations in blood and urine than non-exposed referents. Workers in the electrolytic production of aluminium had higher urine but not blood concentrations than the referents. ...

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...

While the geometry of aerospace assemblies is carefully controlled, for many industrial applications such as marine structures bond line thickness can vary significantly. In this study epoxy adhesive joints of different thicknesses between aluminium substrates have been characterized using physicochemical analyses (differential scanning calorimetry, DSC; dynamic mechanical analysis, DMA; spectr...
