The recent development of wireless sensors for structural health monitoring has revealed their strong dependency on portable, limited battery supplies. Unlike current wireless sensors, passive radio frequency identification (RFID) systems based on inductive coupling can wirelessly receive power from a portable reader while transmitting collected data back. In this paper, preliminary results of ...

Traditional thin-film energy-storage devices consist of stacked layers of active films on two-dimensional substrates and do not exploit the third dimension. Fully three-dimensional thin-film devices would allow energy storage in bulk materials with arbitrary form factors and with mechanical properties unique to bulk materials such as compressibility. Here we show three-dimensional energy-storag...

Thin copper films on silicon constitute model systems to investigate the influence of lattice strain on activity in heterogeneous catalysis. Thin copper films on silicon were investigated by ultraviolet photoelectron spectroscopy (UPS) to reveal the effect of strain in the copper films on the electronic structure of the surface. For cleaned and adsorbate-free surfaces, no effect of strain on th...

Abstract Thin copper films with thickness ∼28 nm deposited on SiO 2 substrate the vacuum electron beam evaporation method and treated by UV-ozone are studied. It was found that a treatment of film causes rapid formation thin ∼3-4 oxide film. XPS analysis showed CuO predominates in this The formed effectively protects against following oxidation. presented is simpler cheaper approach compared to...

Novel chitosan-zinc copper oxide (Zn1-xCuxO) composites were electrochemically synthesized through galvanostatic deposition. The prepared chitosan-based composite thin films were elaborately investigated to determine their structural, morphological, compositional, impedance, and corrosion properties. X-ray diffraction analysis was performed to reveal their structural orientation of composite th...

The effect of surface bond-order loss on the classical resistivity of metallic polycrystalline thin films is studied. The potential barriers due to grain boundaries considered here contain square-well depressions on both sides taking into account the effect of surface bond-order loss for the grains in a film. Electron scattering by film surfaces is also considered following the lines of Fuchs’ ...

In this research work, silica nano-porous thin films were deposited on glass substrates by layer by layer method. The thin films were calcinated at various calcination temperatures (200, 300, 400, and 500 °C). The morphology, surface characteristics, surface roughness and hydrophilic properties of the thin films were investigated by field emission scanning electron microscopy, attenuated total ...

The potentiodynamic behaviour of copper in brine solutions was studies. Auger and photo-electron spectroscopy were used together with electrochemical methods. It is demostrated that the passivation observed in potentiodynamic curves is due to a surface film formation on a copper electrode. It is concluded that this film must be copper (I) chloride in nature. Effect of different factors on poten...
