Anode aluminum oxide-supported thin-film fuel cells having a sub-500-nm-thick bilayered electrolyte comprising a gadolinium-doped ceria (GDC) layer and an yttria-stabilized zirconia (YSZ) layer were fabricated and electrochemically characterized in order to investigate the effect of the YSZ protective layer. The highly dense and thin YSZ layer acted as a blockage against electron and oxygen per...

cu(in,ga)se2 thin films (cigs) on metallic substrate (titanium, molybdenum, aluminum, stainless steel) were prepared by a two-step selenization of co-evaporated metallic precursors in se-containing environment under n2 gas flow. structural properties of prepared thin film were studied. to characterize the optical quality and intrinsic defect nature low-temperature photoluminescence, were perfor...

We study the behaviour of the steady-state voltage potential in a material composed of a two-dimensional object surrounded by a very rough thin layer and embedded in an ambient medium. The roughness of the layer is described by a quasi ε–periodic function, ε being a small parameter, while the mean thickness of the layer is of magnitude ε, where β ∈ (0, 1). Using the twoscale analysis, we replac...

In the present work, three different modes of heat conduction, diffusion, thermal wave, and dual-phase lag, across a thin layer subjected to constant temperature insulated boundary conditions are compared by using finite element solution. The model is developed considering relaxation time flux gradient for single element. After assembling all elements, number algebraic equations obtained solved...

Thin prepregs with thickness of less than 0.06 mm support flexible lamination design because it is possible to apply various stacking sequences. The objective this study elucidate the effects layer and sequence on open-hole compressive (OHC) strength for thin-ply carbon fiber reinforced plastic composite (CFRP) laminates. Details OHC CFRP laminates were evaluated experimentally. Furthermore, fi...

OBJECTIVES The bond of adhesive luting cements to the tooth tissues and restorative materials is expected to hinder their transverse contraction for the layer thickness applied in dental restorations. It was hypothesized that the hindering of the transverse deformation will influence the relation between stress and strain (the stiffness) in the direction perpendicular to the substrate surface. ...

The work is devoted to the heat exchange of a nuclear reactor. Attention was paid mathematical modeling temperature field fuel element and thin gas layer. It assumed that thermal contact between solid–interlayer system ideal. Methods differentiation, integration approximate methods were used for numerical modeling. dependence conductivity plutonium dioxide on also taken into account.
