The hybrid effect of Al and Cr in zinc bath on galvanizing coatings were studied by means of scanning electron microscope (SEM) and energy dispersive X-ray spectroscope (EDS), coupled with hot-dip galvanizing experiments. A new phase T1 was found in the coating, and the ζ phase was absent when hot-dip galvanizing at 480 °C. When Cr added zinc bath were alloyed with 0.1 wt.% Al, coating was composed of δ, ζ, η and T1 phases; when Cr added zinc bath were alloyed with 0.2 wt.% Al, δ phase layer became thinner, ζ changed from even layer to blocky crystals, and diffuse-Δ coexisted with the ζ phase. The morphology evolution of galvanizing coating was analyzed and the hybrid effect of Al and Cr were discussed with diffusion path theory.

Nb, Ta and V are prototype substances for the study of the endothermic reactions of H with metals. Such metal-hydrogen reactions have gained increased importance due to the application of metal-hydrides in hydrogen- und heat storage devices. Electron microscopy and diffraction were demonstrated to be excellent methods in the study of hydride morphologies and structures (1). - Figures 1 and 2 show the NbH and TaH phase diagrams (2,3,4). EM techniques have contributed substantially to the elucidation of the structures and domain configurations of phases β, ζ and ε (1,4). Precision length measurement techniques of distances in reciprocal space (5) recently led to a detailed understanding of the distortions of the unit cells of phases ζ and ε (4). In the same work (4) the existence of the new phase η was shown. It is stable near -68 °C. The sequence of transitions is thus below 70 %.

New Phase

The creative character of reading is revealed through the elucidation of its temporal constitutions and consideration of some practical aspects of this phenomenon. Reading isn’t intellectual, aesthetical procedure, but co-being between a text and a reader. Reading is one of the ways of becoming and forming in human being specific metaphysical organs. Thanks to them there are some actual conditions of freedom, love, faith, virtue, responsibility etc. Impression as point-wise part of time, orienting on presence and changing with every new phase of reading text is shown. Impression isn’t feeling, but invasion, that includes intensity, completeness of action. That’s why reading text should impress and invade in limits of being of a reader, catch them, hold them by its energy his attention. Retention as primary memory of read text and holding some information during its distancing from the point of impression is researched. Possibilities of using of some technics of reading – reading out loud of dialogues of Plato, reflexive reading, close reading etc.

AbstractWe studied the initial stages of the electrodeposition of Pb in the presence of chlorine ions on Cu(100), using an oblique-incidence optical reflectivity difference (OIRD) technique. The OI-RD results reveal that immediately following the underpotential deposition (UPD) of the first Pb monolayer, two different types of bulk-phase films grow depending upon the magnitude of overpotential and cyclic voltammetry (CV) scan rate. At low overpotentials and/or slow scan rates, we propose that a bulk-phase Pb film grows on top of the UPD monolayer. At high overpotentials and/or fast scan rates, either a PbO, PbCl2, or a rough Pb bulk-phase layer grows on top of the UPD layer such that the reflectivity difference signal from such a film has an opposite sign.

Solar has become one of the fastest growing renewable energy sources. With the push towards sustainability it is an excellent solution to resolve the issue of our diminishing finite resources. Alternative photovoltaic systems are of much importance to utilize solar energy efficiently. The Cu-chalcopyrite compounds CuInS2 and CuInSe2 and their alloys provide absorber material of high absorption coefficients of the order of 105 cm-1. Cu2ZnSnS4 (CZTS) is more promising material for photovoltaic applications as Zn and Sn are abundant materials of earth’s crust. Further, the preparation of CZTS-ink facilitates the production of flexible solar cells. The device can be designed with Al doped ZnO as the front contact, n-type window layer (e.g. intrinsic ZnO); an n-type thin film buffer layer (e.g. CdS) and a p-type CZTS absorber layer with Molybdenum (Mo) substrate as back contact. In this study, CZTS films were synthesized by a non-vaccum solvent based process technique from a molecular-ink using a non toxic eco-friendly solvent dimethyl sulfoxide (DMSO). The deposited CZTS films were optimized and characterized by XRD, UV-visible spectroscopy and SEM.

Lossless Dynamic Models of the Quasi-Z-Source Converter FamilyThis paper is devoted to the quasi-Z-source (qZS) converter family. Recently, the qZS-converters have attracted attention because of their specific properties of voltage boost and buck functions with a single switching stage, which could be especially beneficial in renewable energy applications. As main representatives of the qZS-converter family, the traditional quasi-Z-source inverter as well as two novel extended boost quasi-Z-source inverters are discussed. Lossless dynamic models of these topologies are presented and analyzed.
