A 28-year-old woman presented with an axillary eczema that occurred after using deodorants. Patch testing revealed contact allergy to aluminium chloride. With avoidance of aluminium-containing deodorants, the eczema cleared completely. Aluminium and its salts are widely used but contact allergy to them is uncommon. It is occasionally recognised incidentally as a reaction to aluminium Finn Chamb...
Aluminium is one of the trace elements with a moderate toxic effect on living organisms. This study is to assess the influence of aluminium chloride and aluminium hydroxide intake on biochemical parameters in experimental animals for 21 days. Administration of aluminium chloride and aluminium hydroxide at a dose of 300mg/kg of body weight significantly elevates blood serum urea and creatinine c...
This paper describes a method for the sensitive detection of aluminium in biological tissues by real time confocal laser scanning microscopy after staining with lumogallion. The method enabled detection of aluminium > or = 9 micrograms g-1 in bone and is more sensitive than the conventional histochemical methods with aluminium and solochrome azurine, etc. Lumogallion reacts specifically with al...
در این رساله، روشهای احیایی نوین، بسیار موثر و سبز با استفاده از سدیم سیانو بوروهیدرید برای احیای گروههای عاملی کربونیلی، نیترو و اکسیم به صورت زیر ارائه می شود: - احیای ترکیبات کربونیلی با استفاده از nabh3cn در حضور nano fe3o4/h2so4 در دمای اتاق و شرایط بدون حلال - احیای ترکیبات کربونیلی با استفاده از nabh3cn در حضور nano fe3o4@sio2/h2so4 در دمای اتاق و شرایط بدون حلال - احیای ترکیبات کربون...
Precipitation hardening, because it involves the hardening of the material over a prolonged time, is also called age hardening, or ageing. By the appropriate heat treatment of precipitation hardening, the strength or hardness of some heat-treatable aluminium alloys can be enhanced by the formation of nano-meter sized second-phase precipitated particles within the original phase matrix. The fine...
Iliac bone aluminium was determined by neutron activation analysis in 34 patients with chronic renal failure and in eight control subjects. In 17 patients treated by haemodialysis there was a significant increase in the amount of aluminium (mean +/- SE = 152 +/- 30 ppm bone ash). In eight patients treated by haemodialysis and subsequent renal transplantation, bone aluminium was still significan...
Cellulose insulation polymer (paper/pressboard) has been widely used in high voltage direct current (HVDC) transformers. One of the most challenging issues in the insulation material used for HVDC equipment is the space charge accumulation. Effective ways to suppress the space charge injection/accumulation in insulation material is currently a popular research topic. In this study, an aluminium...
Selective laser melting (SLM) offers significant potential for the manufacture of the advanced complex-shaped aluminium matrix composites (AMCs) used in the aerospace and automotive domains. Previous studies have indicated that advanced composite powders suitable for SLM include spherical powders with homogeneous reinforcement distribution, a particle size of less than 100 μm and good flowabili...
Aluminium Phosphide poisoning and glucose‐6‐phosphate dehydrogenase deficiency are two commonly seen clinical presentations in Iran. However, hemolysis associated with Aluminium Phosphide poisoning is very rare. We report a case of concurrent Aluminium Phosphide poisoning and glucose‐6‐phosphate dehydrogenase deficiency in a 24 year old man presenting with intravascular hemolysis. Key words...
