A double helicenic benzothieno–benzothiophene derivative, showing homochiral layers of MM and PP enantiomers in the single crystal phase, behaves as a p-type semiconductor thin-film OFET devices fabricated by both spin coating evaporation.

Thin films of ceramic materials like alumina and silicon carbide are deposited on Inconel substrate by pulsed laser deposition technique using Q-switched Nd: YAG laser. Deposited films are characterized using UV-visible spectrophotometry and X-ray diffraction. Composite microhardness of ceramic coated Inconel system is measured using Knoop indenter and its film hardness is separated using a mat...

The asymptotic strip boundary condition (ASBC) is applied to analyze the solution of the electromagnetic scattering from a conducting cylinder coated with a homogeneous linear material layer and loaded with conducting helical strips. Such homogeneous material layer can be implemented by a conventional dielectric material, a single negative (SNG) or double negative (DNG) meta-material layer. A s...

Coatings of specific materials in few atoms of thickness to several microns on certain substrate is the basic need of society and they attend the regular attention of scientific community working in different domains; decorative and protective coatings, transparent and insulating coatings, coating medical implants and surgical instruments, coatings for drug delivery and security purposes, ultra...

The effect of polymeric coatings on the static fatigue of double-coated optical fibers is investigated. A closed form solution of the tensile stress in the glass fiber under the action of a constant tensile force in the fiber’s axial direction is obtained using viscoelastic theory. The tensile force is applied to the glass fiber and polymeric coatings. The applied tensile fore is gradually tran...

Abstract In the present study, dense Cr and 0.92 Si 0.08 coatings have been deposited on Zircaloy-4 substrates by magnetron sputtering technique. The high-temperature oxidation resistance of is evaluated in 1200 °C steam for 1–4 h. coating shows better than coating. in-situ formed Zr 2 diffusion barrier inhibits mutual Zr. And formation a O 3 /SiO double-layer scale effectively improves single ...
