The performance of organic thin-film transistors (OTFT) for flexible, low cost and disposable “plastic” electronic products advances rapidly: various organic semiconductors display hole or electron carrier mobilities that compare favorably with those of hydrogenated amorphous silicon, the inorganic counterpart for such applications as flexible displays, smart cards and radio frequency identific...

a nanocomposite of polyaniline (pani) with natural clinoptilolite (clino) was prepared by chemical oxidative polymerization of anilinium cations in the presence of clinoptilolite dispersion. the pani/clino nanocomposite was characterized using ftir, xrd and sem techniques as well as electrical conductivity measurement using four point probe technique. cyclic voltammetry analysis was used to inv...

Tin matrix nanocomposite coatings containing ZnO and NiO nanoparticles, both individually combined, were deposited on low carbon steel substrates. The aim was to investigate the effect of reinforcement nanoparticles microstructural morphology thickness tin coatings, modification in interfacial layer between coating substrate, corrosion resistance substrate. Optical scanning electron microscopy ...

Introducing a hydrophobic property to vertically aligned hydrophilic metallic nanorods was investigated experimentally and theoretically. First, platinum nanorod arrays were deposited on flat silicon substrates using a sputter Glancing Angle Deposition Technique (GLAD). Then a thin layer of Teflon (nanopatches) was partially deposited on the tips of platinum nanorod at a glancing angle of θ = 8...

Metallic-dielectric nanocomposites, including Ag-SiO2, Co-SiO2 and WC-SiC, were synthesised on silicon substrates using ion implantation. The electron field emission (FE) properties of these nanocomposites were studied and correlated to their microstructure determined from the measurements of atomic force microscopy, Rutherford backscattering spectroscopy, x-ray photoelectron spectroscopy and t...

BACKGROUND This article reports the authors' development of nanofillers and a resulting nanocomposite. They measured the nanocomposite's properties in vitro in comparison with those of several existing composites (hybrids, microhybrids and microfill). METHODS The authors developed two types of nanofillers: nanomeric particles and nanoclusters. They used optimal combinations of these nanofille...

Nanocomposite thin film coatings of MoS2-added CrN/TiAlN tribological multilayers were prepared by reactive co-sputtering of Ti/Al 50/50 at.%, pure chromium and MoS2 targets of the independently d.c. driven unbalanced magnetrons. Nano-scaled tri-layer system with periodic thickness in a range of 4-10 nm of CrN, TiAlN and MoS2 compound layer with a broad interface, in which the composition is co...

In this study, boroxine derivative (K₂[B₃O₃F₄OH]) was tested as an inhibitor of horseradish peroxidase (HRP) by spectrophotometric and electrochemical methods. The activity of horseradish peroxidase was first studied under steady-state kinetic conditions by a spectrophotometric method which required the use of guaiacol as a second substrate to measure guaiacol peroxidation. The results of this ...

A one pot and environmentally benign synthetic route for plasmonic photocatalytic Ag@AgCl nanoparticles in a PVA-dissolved aqueous solution system is presented. The synthesized AgCl has a cubic-shape and its edge length can be controlled from ~57 to ~170 nm by varying the reaction temperature. In this system, PVA was used as a stabilizer for the formation of Ag@AgCl nanoparticles through intera...

Nanocrystalline Co2MnSi Heusler alloy films were deposited on the PZN-PT substrates by a composition gradient sputtering method. It is revealed that this multiferroic heterostructure shows very strong magnetoelectric coupling, leading to continuously tunable microwave frequency characteristics by electric field. With the increase of electric field intensity from 0 to 6 kV/cm, the magnetic aniso...
