nano-sized γ-al2o3 was synthesized successfully by a simple method using al2(so4)3·18h2o as aluminium source and in the presence of polyethylene glycol (peg 2000). ftir spectroscopy, x-ray diffraction (xrd), scanning electron microscope (sem) and transmission electron microscope (tem) were used to characterize the structure and morphology of synthesized powder. the results showed that peg playe...

Histamine is an indicator of food quality and indispensable in the efficient functioning of various physiological systems. Rapid and sensitive determination of histamine is urgently needed in food analysis and clinical diagnostics. Traditional histamine detection methods require qualified personnel, need complex operation processes, and are time-consuming. In this study, a biofunctionalized nan...

Abstract The lubricity of coatings made from different types carbon nanoparticles such as onions, nanohorns and nanotubes is investigated on line-patterned AISI 304 stainless-steel substrates using ball-on-disc tribometry over 200,000 sliding cycles. Picosecond direct laser interference patterning used to create line-patterns the substrate surfaces which are subsequently coated by electrophoret...

Adhesive bonding technology is being used in a variety of modern industries, including the automotive, aerospace, maritime, construction, defense and so on. On the other side, polymeric nano - composites attracted both academic and industrial interests in the past decades. The scope of this paper is experimental investigation on the effects of the addition of Alpha-alumina nanoparticles to the ...

One strategy in creating functional nanostructures is templating where active nanoparticles are arranged on a regular nanoscale array of anchor sites on an inert substrate. An extraordinarily well ordered substrate with a 4.2 nm template periodicity is an alumina (aluminum oxide) film grown on a Ni3Al(111) metallic alloy support. Templating on the alumina film is facilitated by a dot and a netw...
