Thermal regime defines oil and gas potentials in the Volga region

High-precision temperature logging conducted in deep and superdeep wells after restoring their thermal regimes have been used for drawing a temperature map of the central Volga region for a depth of 1000 m. The temperature survey has determined major thermal features of the region and outlined its oil and gas prospects. © 2010, European Association of Geoscientists and Engineers

Quasiparticle interference and strong electron-mode coupling in the quasi-one-dimensional bands of Sr2RuO4

The single-layered ruthenate Sr$_2$RuO$_4$ has attracted a great deal of interest as a spin-triplet superconductor with an order parameter that may potentially break time reversal invariance and host half-quantized vortices with Majorana zero modes. While the actual nature of the superconducting state is still a matter of controversy, it has long been believed that it condenses from a metallic state that is well described by a conventional Fermi liquid. In this work we use a combination of Fourier transform scanning tunneling spectroscopy (FT-STS) and momentum resolved electron energy loss spectroscopy (M-EELS) to probe interaction effects in the normal state of Sr$_2$RuO$_4$. Our high-resolution FT-STS data show signatures of the \beta-band with a distinctly quasi-one-dimensional (1D) character. The band dispersion reveals surprisingly strong interaction effects that dramatically renormalize the Fermi velocity, suggesting that the normal state of Sr$_2$RuO$_4$ is that of a 'correlated metal' where correlations are strengthened by the quasi 1D nature of the bands. In addition, kinks at energies of approximately 10meV, 38meV and 70meV are observed. By comparing STM and M-EELS data we show that the two higher energy features arise from coupling with collective modes. The strong correlation effects and the kinks in the quasi 1D bands may provide important information for understanding the superconducting state. This work opens up a unique approach to revealing the superconducting order parameter in this compound

Crystal Growth, Dynamic and Charge Transfer Properties of New Coronene Charge Transfer Complexes

© 2015 American Chemical Society. Two new coronene charge transfer complexes with F4-TCNQ of 2:1 and 1:1:1 (solvate with acetonitrile, MeCN) stoichiometry were obtained using crystal growth procedures from the solution and vapor phase. It was shown that mobility of coronene molecules in crystals is more affected by the asymmetry of its surrounding than by the composition and degree of charge transfer and interstack interactions. The combination of X-ray diffraction and electrochemistry in the solid state and a time-resolved one in solution allowed us to clarify the nucleation in solution showing that the formation of 2:1 coronene/F4-TCNQ complexes is thermodynamically preferable. The X-ray single crystal data for pristine coronene showed the crystal structure to be the same as at ambient temperature, raising doubt about the previously reported phase transitions at 140-180 K

Infrastructural Bases for Improving the Activities of the Arbitrazh Court of the Cassation in terms of Analysis and Generalization of Judicial Practice

The paper draws attention to the need for a deeper study of infrastructural conditions for the effective operation of the arbitrazh court of cassation. Based on the analysis of scientific publications, regulatory documents and problems in practical activities on the topic of the work, the author proposes three directions for its improvement for discussion. These include the following. Synchronization of law enforcement and generalization of judicial practice on the basis of scientific research methods require further improvement of the scientific qualifications of judges and court employees. Targeted collection and analysis of statistics require acquisition and study of new judicial metrics. It is important to systematize and improve the work of internal review groups (scientific advisory board, expert advisory groups, working groups, departments, etc.) and publicize the results of their recommendations in reviews, press releases and journals. The role of advanced information resources in studying the opinions of persons involved in the case and receiving feedback is also noted. According to the author, account of these components will lead to the fact that at the stage of cassation consideration of cases, judges will resolve problematic issues of substantive and procedural law and stop legal incidents more accurately, thereby minimizing errors in all parts of the judicial system. It is recommended to develop a regulation on analysis groups in the courts of cassation on issues of judicial practice, as well as on the improvement of arbitrazh legislation. The solution of intra-system infrastructure issues, which are deterrents for obtaining legal leaps, will significantly increase the effectiveness of the entire judicial sphere.</jats:p

New methodological aspects the study of prejudice

The work is devoted to the problems of improving the institute prejudice. To improve the legislation on prejudice are encouraged to use the system-institutional approach to the study of legal phenomena. Analysis of prejudice through institutional and systemic approach will create a flexible system of legal regulation. The author identifies the internal and external organizational structure of the Institute of prejudice, prejudice defines media.</jats:p

Strain control of Fermiology and many-body interactions in two-dimensional ruthenates

Here we demonstrate how the Fermi surface topology and quantum many-body interactions can be manipulated via epitaxial strain in the spin-triplet superconductor Sr2RuO4 and its isoelectronic counterpart Ba2RuO4 using oxide molecular beam epitaxy, in situ angle-resolved photoemission spectroscopy, and transport measurements. Near the topological transition of the γ Fermi surface sheet, we observe clear signatures of critical fluctuations, while the quasiparticle mass enhancement is found to increase rapidly and monotonically with increasing Ru-O bond distance. Our work demonstrates the possibilities for using epitaxial strain as a disorder-free means of manipulating emergent properties, many-body interactions, and potentially the superconductivity in correlated materials.Publisher PDFPeer reviewe
