In the present work, a study was made of the properties of a photocatalyst-adsorbent based on metal oxide, which was titanium dioxide (TiO2). The photodegradation activity of two organic dyes under the action of light was analyzed. The effect of the phase composition of the photocatalyst was compared on the example of three modifications of TiO2 - rutile, anatase and their mixture.

This paper provides solution for the task of plane movement of the underwater vehicle using hierarchical control system. Searching A*-algorithm is used for creation of the path plan. Vehicle moves along the stated path under control of position-path regulator on the base of square form. Vehicle, used in this paper features torpedo-like form, two cruise engines and maneuvering device.

The purpose and objectives of this work is to develop methods of planning the path of the mobile autonomous robots operating in environments with unknown location of obstacles. The result of the article is vague planner travel path of autonomous mobile robots for three-dimensional space (3D environments). The results differ from known analogues structure proposed planner, consisting of two interconnected parts, designed for use in horizontal and vertical planes, context-sensitive coordination method "simple" behavior of the mobile robot, a set of rules governing the method of prevention "jam" in the obstacles.

In this paper we study of the local atomic and electronic structure of nanostructured condensed material for rechargeable current sources on the basis of 15mas.%V2O5/Fe/LiF nanocomposite within charge-discharge cycle. Principle component analysis (PCA) of the series of Fe K-edge spectra collected during 1 st charge showing the concentrations of the components Fe, FeF2 and V[FeV]O4. We found the changes in the V oxidation state from the analysis of the experimental Fe K- and V K- XANES spectra. Total and partial density of states of components are presented.

In this paper we study the dynamics of the local atomic structure of new nanostructured condensed material for for rechargeable current sources on the basis of 15mas.%V2O5/Fe/LiF nanocomposite within charge-discharge cycle on the basis of X-ray diffraction (XRD), X-ray absorption spectroscopy (XANES) and of computer simulation. The analysis of the experimental data obtained during the first charge cycle reveals the transformation of iron to more than 50% of iron fluoride (II) , Li ions intercalate into the structure of amorphous V2O5 forming LiVO2 compound.
