Simple synthesis of graphene nanocomposites MgO–rGO and Fe2O3rGO for multifunctional applications
Hummer’s method was used to prepare graphene oxide (GO) by chemical exfoliation of graphite. Simple precipitation method was used for the preparation of hybrid nanocomposites MgO–rGO and Fe2O3–rGO. A 0.3 Molar of corresponding metal nitrate solution and GO solution are used for the preparation process. XRD, FT-IR, and XPS were used to characterize the prepared nanocomposites. The reduction of GO into reduced rGO in the formed nanocomposites was confirmed. Morphological characterization showed the formation of needle-shaped nanocrystals of MgO successfully grown on grapheme nanosheet with average crystallite size 8.4 nm. Hematite nanocomposite Fe2O3– rGO forms rod-shaped crystals with average crystallite size 27.5 nm. The saturation magnetization observed for Fe2O3– rGO is less than reported value for the pure Fe2O3 nanoparticles. Thermal properties of as-prepared hybrid nanocomposites MgO–rGO and Fe2O3–rGO showed thermal stability of the prepared nanocomposite over long range of temperature.
In this paper a study of criminal law mechanism for the protection of property with aim of establishing its relationship with inflation and deflation processes, aggravated in the Russian economy in the current financial crisis. As a result, the author found that the application of the criminal law does not solve the problem of stratification of modern society, but aggravates it.
The subject matter of the article lies between public law and economics. The article contains sources of legal regulation in state corporations, ways of their forming, jurisdiction, priorities and results of its activities achieved in western democracies. The author stresses the dependence of effectiveness of this public law institute on checks and balances as well as individual responsibility, responsibility for doings and refraining from doing by authorities, reputation of officials.
One of the great successes of the law and economics movement has been the use of economic models to explain the structure and function of broad areas of law. The original contributions to this volume epitomize that tradition, offering state-of-the-art research on the many facets of economic modeling in law. The contributors employ a variety of economic methodologies to explore a wide range of topics, including torts, contracts, property, crime, employment, the environment, and legal procedure. This depth and breadth of scholarship reflect the continuing vitality of the economic approach to law, offering an illuminating look into the future of the field and providing inspiration and guidance for the next generation of theorists. This timely volume will appeal to students, professors and researchers in both law and economics, particularly those with an interest in the theoretical and practical intersections of the two fields.
Research is carried out article criminally-legal mechanism property protection, its communication with the inflationary and deflationary processes which have become aggravated in the conditions of financial crisis. By the analysis of communication of the criminal law with economic processes it is established that it aggravates property stratification of a modern society.
The dynamics of a two-component Davydov-Scott (DS) soliton with a small mismatch of the initial location or velocity of the high-frequency (HF) component was investigated within the framework of the Zakharov-type system of two coupled equations for the HF and low-frequency (LF) fields. In this system, the HF field is described by the linear Schrödinger equation with the potential generated by the LF component varying in time and space. The LF component in this system is described by the Korteweg-de Vries equation with a term of quadratic influence of the HF field on the LF field. The frequency of the DS soliton`s component oscillation was found analytically using the balance equation. The perturbed DS soliton was shown to be stable. The analytical results were confirmed by numerical simulations.
Radiation conditions are described for various space regions, radiation-induced effects in spacecraft materials and equipment components are considered and information on theoretical, computational, and experimental methods for studying radiation effects are presented. The peculiarities of radiation effects on nanostructures and some problems related to modeling and radiation testing of such structures are considered.
This volume presents new results in the study and optimization of information transmission models in telecommunication networks using different approaches, mainly based on theiries of queueing systems and queueing networks .
The paper provides a number of proposed draft operational guidelines for technology measurement and includes a number of tentative technology definitions to be used for statistical purposes, principles for identification and classification of potentially growing technology areas, suggestions on the survey strategies and indicators. These are the key components of an internationally harmonized framework for collecting and interpreting technology data that would need to be further developed through a broader consultation process. A summary of definitions of technology already available in OECD manuals and the stocktaking results are provided in the Annex section.
