Management of the Activities that Address the Problems of Consumers Rights Protection as Regards Financial and Insurance Services Delivered to the Population Exposed to the Large-Scale High Water in the Amur Region

Worked out by the Rospotrebnadzor Administration in cooperation with the Amur Region Government and the head office of the Central Bank of Russia was a plan of operation aimed at the provision of financial loan consumers’ rights protection through the implementation of simplified repayment procedure. Rospotrebnadzor Administration charged itself with the responsibility to inform and provide counseling to affected borrowers and to gather the data on their numbers and the volume of the credits allowed. The measures undertaken made it possible to delay the deadlines and decision making on the financial problems emerged, which concerned the repayment of debts, all in order to use the available sums for elimination of consequences and aftermaths of the disaster

Tolerance of topological surface states towards magnetic moments: Fe on Bi2Te3 and Bi2Se3

Topological insulators(1-8) are a novel form of matter which features metallic surface states with quasirelativistic dispersion similar to graphene(9). Unlike graphene, the locking of spin and momentum and the protection by time-reversal symmetry(1-8) open up tremendous additional possibilities for external control of transport properties(10-18). Here we show by angle-resolved photoelectron spectroscopy that the topological sur-face states of Bi2Te3 and Bi2Se3 are stable against the deposition of Fe without opening a band gap. This stability extends to low submonolayer coverages meaning that the band gap reported recently(19) for Fe on Bi2Se3 is incorrect as well as to complete monolayers meaning that topological surface states can very well exist at interfaces with ferromagnets in future devices.Comment: 10 pages, 3 figures, submitted to Nature Physics 22.

Nonmagnetic band gap at the Dirac point of the magnetic topological insulator Bi1 xMnx 2 Se3

Magnetic doping is expected to open a band gap at the Dirac point of topological insulators by breaking time-reversal symmetry and to enable novel topological phases. Epitaxial (Bi$_{1-x}$Mn$_{x}$)$_{2}$Se$_{3}$ is a prototypical magnetic topological insulator with a pronounced surface band gap of $\sim100$ meV. We show that this gap is neither due to ferromagnetic order in the bulk or at the surface nor to the local magnetic moment of the Mn, making the system unsuitable for realizing the novel phases. We further show that Mn doping does not affect the inverted bulk band gap and the system remains topologically nontrivial. We suggest that strong resonant scattering processes cause the gap at the Dirac point and support this by the observation of in-gap states using resonant photoemission. Our findings establish a novel mechanism for gap opening in topological surface states which challenges the currently known conditions for topological protection.Comment: 26 pages, 7 figure

Site- and spin-dependent coupling at the highly ordered h-BN/Co(0001) interface

Using photoelectron diffraction and spectroscopy, we explore the structural and electronic properties of the hexagonal boron nitride (h-BN) monolayer epitaxially grown on the Co(0001) surface. Perfect matching of the lattice parameters allows formation of a well-defined interface where the B atoms occupy the hollow sites while the N atoms are located above the Co atoms. The corrugation of the h-BN monolayer and its distance from the substrate were determined by means of R-factor analysis. The obtained results are in perfect agreement with the density functional theory (DFT) predictions. The electronic structure of the interface is characterized by a significant mixing of the h-BN and Co states. Such hybridized states appear in the h-BN band gap. This allows to obtain atomically resolved scanning tunneling microscopy (STM) images from the formally insulating 2D material being in contact with ferromagnetic metal. The STM images reveal mainly the nitrogen sublattice due to a dominating contribution of nitrogen orbitals to the electronic states at the Fermi level. We believe that the high quality, well-defined structure and interesting electronic properties make the h-BN/Co(0001) interface suitable for spintronic applications.L.V.Ya. acknowledges the RSF (Grant No. 16-42-01093).

In Situ XPS Studies of Solid Electrolyte Electroreduction Through Graphene Electrode

The current interest in research and development of solid electrolytes for battery systems dictates a necessity to evaluate their electrochemical stability in a wide potential range. It is supposed that the stability and properties of the interface formed between the electrode and solid electrolyte at the applied potential (the analog of solid electrolyte interphase (SEI) in liquid electrolytes) are of great importance for the battery operation. While the electrochemical techniques can provide the knowledge of a stability window of the solid electrolyte, a direct method, which helps to trace chemical changes, is still missing, due to the difficulty to reach the interface between the solid electrolyte and thick electrode material. In this paper, we propose to use two-layer graphene transferred directly on the solid electrolyte as the electrode transparent for photoelectrons. Such an electrode is thin enough to probe the interface by X-ray photoelectron spectroscopy to trace the occurring chemical changes. To demonstrate this possibility, we have investigated the electrochemical reduction of Li1.5Al0.5Ge1.5(PO4)3 (LAGP) glass-ceramic electrolyte by in situ XPS
