During the past few decades, materials design has shifted emphasis to pursue low cost, quality, light weight, environment friendliness, and performance. Aluminium matrix composites are important class of engineering materials used in aerospace, automotive, engineering, defence and other industries because of their lower density, higher specific strength, and better physical and mechanical prope...

The increasing use of aluminimum in packaging applications results many different aluminium-based products ending up consumer mixed-waste bins. This waste is typically incinerated, generating an aluminium-containing bottom ash. current work investigates the recyclability aluminium fraction ash from incineration plants USA, UK and Denmark. Incinerated Al-samples size fractions (2–6 mm, 6–12 mm 1...

the effects of aluminium and aluminium-citrate on some serum parameters related to carbohydrate metabolism in male wistar rats were investigated. daily intraperitoneal administrations of 1 mg/kg body weight of aluminium or aluminiumcitrate (1: 1) for 50 days led to the elevation of serum insulin by 24 or 40 percent respectively, with the concomitant decrease in serum glucose concentrations by 1...

Global energy demand is rising due to the rapid development and adoption of new technologies in every sector. Hence, there a need introduce clean source that does not cause damage environment. Aluminium-air battery with its high theoretical specific volumetric capacity an exciting alternative for post-lithium storage has been at forefront research years. However, conventional aqueous electrolyt...

INTRODUCTION Aluminium is a known neurotoxin and occupational exposure to aluminium has been implicated in neurological disease including Alzheimer's disease. Here we present the first comprehensive and unequivocal data demonstrating significantly elevated brain aluminium content in an individual occupationally exposed to aluminium. CASE PRESENTATION A 66-year-old Caucasian man who died with ...

Nickel oxide (NiO) nanotubes have been produced for the first time via a template processing method. The synthesis involved a two step chemical eaction in which nickel hydroxide (Ni(OH)2) nanotubes were firstly formed within the walls of an anodic aluminium oxide (AAO) template. The ◦ emplate was then dissolved away using concentrated NaOH, and the freed nanotubes were converted to NiO by heat ...

Surface interaction at the worksheet/worksheet interface during resistance spot welding of aluminium alloy 5182 with spherical tip electrodes was investigated. Oxide layer cracking and nugget formation were focused. Both experimental work and finite element analysis were employed to explain the contact behaviour at this interface. It was found that sheet separation and thus bending occurred dur...

Key assets for transparent electric contacts in optoelectronic applications are high conductivity and large transparency over extended spectral range. Indium-Tin-Oxide Aluminium-doped-Zinc-oxide commercial examples, with their electrical resembling those of metals, despite, being limited up to 1.5µm. This work introduces smooth compact amorphous thin films n -type semiconducting WO 3-x prepared...

One-dimensional zinc oxide nanorods array exhibit excellent electron mobility and thus hold great potential as photoanode for photoelelctrochemical water splitting. However, the poor absorption of visible light and the prominent surface recombination hider the performance improvement. In this work, Au nanoparticles and aluminium oxide were deposited onto the surface of ZnO nanorods to improve t...
