We report the evolution of uniaxial strain, resulting in an expansion c-axis wurtzite structure by up to 1 %, without significant degradation crystal 30 keV Zr+ implanted epitaxial AlN films, grown on Si substrates. Raman and X-ray absorption spectroscopies demonstrated that dominant defects are ZrAl, VAl VN. The strain can be attributed a weakening Metal-N π bond along c-axis. Monte Carlo simu...

There are unexplained links between human exposure to aluminium and the incidence, progression and aetiology of Alzheimer's disease. The null hypothesis which underlies any link is that there would be no Alzheimer's disease in the effective absence of a body burden of aluminium. To test this the latter would have to be reduced to and retained at a level that was commensurate with an Alzheimer's...

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...

Abstract Ultra-compact transverse magnetic (TM)-pass polarizer based on silicon sapphire (SOS) platform is proposed and analysed. Low power consumption, high linearity speed of transmission are the major advantages SOS in different commercial applications especially mid infrared region.The suggested structure has bimetallic configuration aluminium doped zinc oxide (AZO) zirconium nitride (ZrN) ...

Abstract The efficiency of machining operation is partly a function the cutting parameters, such as speed, depth cut and feed rate. With an effective performance any tool, manufacturing industries will remain competitive hence strive to meet dynamic service functional requirements expected material. Hence, purpose this research experimentally perform comparative analysis performances SiAlON, ce...

In this work, silicon nitride (Si3N4) thin films were deposited on metallic substrates (aluminium and titanium sheets) by the DC reactive sputtering technique using two different targets (n-type p-type Si wafers) as well Ar:N2 gas mixing ratios (50:50 70:30). The electrical conductivity of titanium) was measured before after deposition both surfaces substrates. results obtained from work showed...

Boron included aluminium nitride (B-AlN) thin films were synthesized on silicon (Si) substrates through chemical vapour deposition ( CVD ) at 773 K (500 °C). tert-buthylamine (tBuNH2) solution was used as nitrogen source and delivered through gas bubbler. B-AlN thin films were prepared on Si-100 substrates by varying gas mixture ratio of three precursors. The structural properties of the films ...

In this research, geometrical structures of armchair single walled boron nitride nanotube (SWBNNT) and armchair single walled aluminum nitride nanotube (SWAlNNT) were optimized by Density Functional Theory (DFT) in the gas phase, both having the same length of 5 angstrom and n=9, m=9. B3LYP/6-31G* level of theory have been used to determine and compare electronic properties, n...
