It is known that carbon nanotubes have impressive mechanical properties and it is thought that one of the best ways to realize them is to incorporate nanotubes into composites. The highest levels of stiffness and strength are obtained for composites with the reinforcing fibers aligned in one direction. It has also been recognized that for any nanocomposite to realize its full potential in terms...

Orientated ferromagnetic Ni0.89Fe0.11 nanoparticle/polymer nanofibres were made by electrospinning a solution containing iron(III) nitrate nonahydrate, nickel(II) acetate tetrahydrate, polyvinylpyrrolidone, and acetic acid in methanol thermally processed Ar then 95%Ar:5%H2 up to 620 °C. There was distribution nanofibre widths after with wider (average width 440 nm) some thinner 120 nanofibres. ...

There is a general lack of publications on the acoustical and related non-acoustical properties nanofibrous media. This work attempts to contribute this gap highlight problems associated with acoustic non-acoustic characterisation these materials. The work, presumably for first time, applies Biot- Darcy-type mathematical models explain observed behaviours nanofibres. It identifies theoretical g...

Polymeric fibres with small radii (such as ≤125 nm) are delicate to handle and should be laid down on a solid substrate to obtain practical devices. However, placing these nanofibres on commonly used glass substrates prevents them from guiding light. In this study, we numerically and experimentally demonstrate that when the nanofibre is placed on a suitable dielectric multilayer, it supports a ...

We describe a method to fabricate, transfer and validate via image processing nanofibre-based, unique security marks ('nanotags') for anti-counterfeiting purposes. Epitaxial surface growth of oligophenylenes on a heated muscovite mica crystal results in a thin film of mutually aligned nanofibres with dimensions of tens of nanometres in height, hundreds of nanometres in width and tens to hundred...

Organic materials have revolutionized optoelectronics by their processability, flexibility and low cost, with application to light-emitting devices for full-colour screens, solar cells and lasers. Some low-dimensional organic semiconductor structures exhibit properties resembling those of inorganics, such as polarized emission and enhanced electroluminescence. One-dimensional metallic, III-V an...

Rechargeable metal-air batteries are considered a promising energy storage solution owing to their high theoretical energy density. The major obstacles to realising this technology include the slow kinetics of oxygen reduction and evolution on the cathode (air electrode) upon battery discharging and charging, respectively. Here, we report non-precious metal oxide catalysts based on spinel-type ...

The teeth of limpets exploit distinctive composite nanostructures consisting of high volume fractions of reinforcing goethite nanofibres within a softer protein phase to provide mechanical integrity when rasping over rock surfaces during feeding. The tensile strength of discrete volumes of limpet tooth material measured using in situ atomic force microscopy was found to range from 3.0 to 6.5 GP...
