16 Multilayered structures with 14 to 50 nm periods composed of titanium and two different 17 titanium oxides, TiO and TiO2, were accurately produced by DC magnetron sputtering 18 using the reactive gas pulsing process (RGPP). Structure and composition of these 19 periodic TiO2/TiO/Ti stacks were investigated by X-ray diffraction (XRD) and 20 transmission electronic microscope (TEM) techniques....

The transport and magnetotransport properties of the metallic and ferromagnetic SrRuO3 SRO and the metallic and paramagnetic LaNiO3 LNO epitaxial thin films have been investigated in fields up to 55 T at temperatures down to 1.8 K. At low temperatures both samples display a well-defined resistivity minimum. We argue that this behavior is due to the increasing relevance of quantum corrections to...

study on polsar target detection essentially requires the cattering information and polarimetric statistical data. theoretical analysis shows that some terms of the second order scattering matrices such as coherence and covariance matrix clearly show the differences between nonsymmetrical man-made objects and natural clatters which being reflection symmetric. using the model derived from these ...

The paper presents the results of experiments on reduction copper oxides formed during heat treatment metallic samples in air. necessary condition is presence a muffle made material with higher electron affinity (lower standard electrode potential) compared to copper. Replacing nitrogen composition atmosphere an equal proportion argon does not change observed redox pattern. Our indicate electro...

Two-dimensional (2D) molybdenum oxides at their various stoichiometries are promising candidates for generating plasmon resonances in visible light range. Herein, we demonstrate plasmonic 2D molybdenum oxide flakes for gas sensing applications, in which hydrogen (H2) is selected as a model gas. The 2D molybdenum oxide flakes are obtained using a grinding-assisted liquid exfoliation method and e...

Infrared spectroscopy is used to investigate the electronic structure and charge carrier relaxation in crystalline films of CrO2 which is the simplest of all half-metallic ferromagnets. Chromium dioxide is a bad metal at room temperature but it has a remarkably low residual resistivity (,5 mV cm) despite the small spectral weight associated with free carrier absorption. The infrared measurement...

The effect of the presence of an Fe-Cr alloy metallic interconnect on the performance and stability of La(0.8)Sr(0.2)MnO3 (LSM) oxygen electrodes is studied for the first time under solid oxide electrolysis cell (SOEC) operating conditions at 800 °C. The presence of the Fe-Cr interconnect accelerates the degradation and delamination processes of the LSM oxygen electrodes. The disintegration of ...

Let R be a commutative ring with 1 and M left unitary R-module. In this paper, we give generalization for the notions of compressible (retractable) Modules. We study s-essentially (s-essentially retractable). some their advantages, properties, characterizations examples. also relation between retractable modules) classes modules.
