We have studied the effect of thermal evaporation rate on the basic physical properties of glassy (As2S3) x (As2Se3)1−x thin films on glass substrates and have determined the optimal range of deposition rates corresponding to the highest photosensitivity and long-term stability of the films. The results are interprete…

The influence on the growth morphology of the spherical crystal in the undercooled melt imposed by the far field flow is studied by the asymptotic method. It is shown that the far field flow leads to convection in the melt such that the front interface of a growing spherical crystal grows into the undercooled melt in…

The method of moments (MoM), physical optics (PO) and geometrical optics (GO) are compared for analysis of dielectric lenses. It is found that MoM can be used (with normal computers) for diameters of the lens up to 15 λ, λ being the wavelength, whereas the approximate methods PO and GO must be used at higher frequenci…

Conventional powder metallurgy processing can produce copper green compacts with density less than 8.3 g/cm3 (a relative density of 93%). Performances of these conventionally compacted materials are substantially lower than their full density counterparts. Warm compaction, which is a simple and economical forming proc…

The effect of the pore size of microfilters installed in a supercritical (SC-) CO2 bubbling device on the concentration of CO2 dissolved in the solution was investigated. Dissolved CO2 concentration in the solution treated with a microfilter was approximately 27% higher than that without a microfilter for lower CO2/sa…
