The relation between chemical composition, microstructure and oxidation properties has been investigated on various FeAl based alloys, the aim being to induce changes in the microstructure of the compound by selective oxidation of aluminium. Oxidation kinetics that was evaluated on bulk specimens showed that, due to fast diffusion in the alloys, no composition gradient is formed during the alum...

The small intestine is the largest component of the digestive tract and the major site of digestion and absorption. Aluminium compounds are used in pharmaceuticals and in water treatment processes. The purpose of this experiment was to evaluate the possible effects that aluminium chloride exposure could have on the histology of the small intestine of wistar rats. The wistar rats were divided in...

The composition of the gaseous phases during pyrolytic laser-induced chemical vapor deposition (LCVD) of aluminium from triisobutylaluminium (TIBA) and trimethylamine alane (TMAA) (aluminium trihydride trimethylamine) was determined. The analysis was carried out by means of quadrupole mass spectrometer (QMS) in closed reaction cell. The developed arrangement for sampling allowed in situ analyse...

Electrolyte is a key material for success in the research and development of next-generation rechargeable batteries. Aluminium rechargeable batteries that use aluminium (Al) metals as anode materials are attractive candidates for next-generation batteries, though they have not been developed yet due to the lack of practically useful electrolytes. Here we present, for the first time, non-corrosi...

Bone biopsies from a group of 16 patients in chronic renal failure treated by intermittent haemodialysis were available for histoquantitative and histochemical assessment before and after the introduction of reverse osmosis treatment of the dialysis fluid. This treatment reduced the aluminium concentration of the fluid from 1.15 mg/l to less than 0.06 mg/l. After the changeover there was an inc...

A validation study in order to evaluate the efficiency of the inductively coupled plasma optical emission spectrometry (ICP-OES) in the analysis of minor elements (Manganese, Chromium, Copper, Iron and Titanium) in aluminium alloys was carried out. Aluminium casting samples were obtained from addition to aluminium baths of compressed powder compacts of each alloying element and aluminium (minit...

Additive Manufacturing offers geometric freedom excellently suited for topology optimized light weight designs. Ideally these should be produced from materials of high strength to weight ratio such as aluminium-copper alloys. Yet these are considered unsuitable for welding. With Laser Beam Melting of Metals in powder bed (LBM), the only class of aluminium alloys widely processed is that of alum...

A retrospective analysis of 584 cases of acute poisoning admitted with a medical emergency to the Department of Medicine, GTB Hospital, Delhi, over a three-year period. The patients were analysed with respect to the age, sex, mode of poisoning, type of poison consumed and mortality. Of these, 42.63% were aged 20-30 years. Poisoning was used as a suicidal agent by 63.8% of the patients. The natu...

To verify whether aluminium phytotoxicity causes oxidative stress in developing greengram seedlings, the present investigation was carried out. An uniform decrease in root and shoot elongations was marked as the primary signs of aluminium injury. A significant increase in lipid peroxidation measured in terms of TBARS content was noticed which was also correlated with an increase in membrane inj...

Catalyst supports with novel chemical and physical properties are needed for producing new families of catalytic materials. The goals of this work were to demonstrate the preparation of aluminium nitride type materials and evaluate their properties as catalyst supports. To obtain aluminium nitride in high-surface-area form suitable for catalyst applications, porous silica and alumina supports w...
