The relationship between aluminium toxicity and iron metabolism was studied. Male rats were exposed to aluminium by daily intraperitoneal injection of 40pmolelkg body weight. After 45 days, aluminium intoxified rats had a significant loweredserum ferritin (55%), iron (42%), TIBC (25%) and hemoglobin(31%). At thesame time the serum ceruloplasmin level was elevated by 60%. This result shows t...

the aim of this manuscript is to study the implication of aluminium-oxide nanofluid for an amphibious vehicle engine (viable on land and under water) cooling system both analytically and experimentally. to achieve this, a one-dimensional model of the engine cooling system (radiator) is considered through a computational fluid code in which the mass flow rate for a range of the coolant temperatu...

Chiral and achiral macrocyclic bis-diketal diamines, analogs of bicyclam AMD 3100, were synthesized in three steps from the previously obtained 14-membered ring diketal dilactams. Their monoreduction with lithium aluminium hydride gave the corresponding diketal aminolactams. Coupling these with dibromo-p-xylene led to xylyl dimer compounds. A second reduction step yielded the expected bis-diket...

The title compound, hepta-sodium trialuminium tetrakis(diarsenate), has been isolated as single crystals from a solid-state reaction. Its structure, which is isotypic with that of the Na7Fe3(X 2O7)4 (X = As, P) family of compounds, consists of AlO6 octa-hedra sharing their vertices with As2O7 groups, forming a three-dimensional [Al3(As2O7)4]∞ framework incorporating channels occupied by the sod...

The title compound, [Al(CH3)2(C30H41O)] is synthesized by the reaction of 2,6-di-adamantyl-4-tert-butyl-phenol with Al(CH3)3 in a nitro-gen atmosphere. In the mol-ecule, the coordination geometry around the Al(III) atom is slightly distorted C2O trigonal (the sum of the bond angles subtended at Al atom being 359.9°), which is rarely reported for organometallic aluminium compounds. The coordinat...

Aluminium is the world’s second most-used metal after steel and the aluminium production industry is the largest, in volume of metal produced, in non-ferrous metal industry. In this study, results of the material flows (country and global scales) related to the production and use of aluminium and energy consumption in 1980 to 2012 were separately analysed. Also, overview of the current status o...

Single crystals of trilithium(I) aluminium(III) bis-[dioxidomolybdenum(VI)] dioxide bis-[arsenate(V)], Li(3)AlMo(2)As(2)O(14), have been prepared by solid-state reaction at 788 K. The structure consists of AsO(4) tetra-hedra, AlO(6) octa-hedra and Mo(2)O(10) groups sharing corners to form a three-dimensional framework containing channels running respectively along the [100] and [010] directions...

Some current methods for the determination of both particulate and gaseous compounds of fluorine, present in air as pollutants, are described and compared. The operation included sampling of the air, the separation of fluoride from interfering substances and its final determination. Results obtained for the separation of fluoride by distillation and by other techniques of microdiffusion are pre...

A simple, conventional TLC method has been established for separation of clopidogrel and its hydrolytic product SR 26334, the main impurity in clopidogrel. Use of aluminium foil-backed silica gel 60F254 plates with n-heptane–tetrahydrofuran, 1:1 (v/v), as mobile phase, enabled successful separation of clopidogrel in high excess from the impurity. The separated compounds were detected at 230 nm....
