Femtosecond luminescence of graphene and graphite is studied from near- to mid-infrared regions. Remarkable reduction of lifetime at 0.3 eV in mono- and bi-layer graphenes is found, indicating carrier cooling due to interaction with substrate.
A new complex [Ni4(dhbd)4•8H2O]•13H2O (1) (H4dhbd = 2,3-dihydroxy butanedioic acid) has been synthesized and its structure (C16H16O45Ni4, Mr = 1163.13)was determined by single-crystal X-ray diffraction analysis.The crystal belongs to the monoclinic system, space group P21/c with a = 13.700(5), b = 17.143(5), c = 18.59…
The theory of linear magnetoelectric effect in magnetostrictive-piezoelectric bilayer structure is presented taking into account the dependence of mechanical oscillations’ strain amplitude on the specimen thickness for structures in the shape of a rectangular plate. The expression for frequency dependence of the ME ef…
2,5-Xylenol is a valuable intermediate for the preparation of phenolic resins, dyes, antiseptics, etc 1 . It was originally extracted from coal tar and then synthesized by chlorination or sulfonation of p-xylene 2 . But there are some drawbacks with these synthetic processes, such as multistep procedures and harsh con…
The is offered approach to the assessment of thermodynamic condition of asphalt concrete pavement refusing labor-consuming procedure of cutting out and analisys of samples from pavement layer. Implementation of probabilistic approach is economically effective when monitoring a network of highways in the Omsk region.
The m aterial behavior of three N i-base superalloys ( Inconel 718, Allvac 718Plus and Haynes 282) during cyclic therm o-m echanical loading was investigated. Stress controlled therm o-m echanical tests were carried out at tem peratures above 700 C and different levels of m axim um compressive stress using a Gleeble 3…
German-based test station manufacturer FuelCon has developed an evaporator assembly with low-pulsation steam generation, for its Evaluator-HT series of test stations for solid oxide electrolyser cells (SOECs). Low-pulsation steam generation provides optimum test conditions for the further development of SOEC electroly…
Non-uniformity in cross-linked rubber is one of important factors to control mechanical properties in rubber. This review presents an analysis of the non-uniformity by using small angle neutron scattering (SANS) method. In the method, the rubber is swollen by solvent and the non-uniformity as well as the network struc…
The following topics are dealt with: concentrated solar power systems; fuel cell; energy harvesting; irreversible solar refrigerator; wind turbine; solar parabolic concentrator; solar collector; thermal energy storage; and nanocomposite material.
Transient absorption spectroscopy has been employed to investigate three photo–active compounds; azobenzene, foldamer controlled by azobenzene, and oxazine. These compounds all have absorption in the ultra–violet regions responsible for their photo–active behavior. Due to this, the current transient absorption setup h…
Solid oxide fuel cells (SOFCs) are promising power generation systems because of their high energy conversion efficiency, fuel flexibility, and low emissions. High-temperature operation of SOFCs enables the internal reforming of fuels such as hydrocarbons and alcohols in the cell chamber, which leads to the constructi…

Η οργανοκατάλυση αποτελεί μια ταχύτατα αναπτυσσόμενη και ακμάζουσα περιοχή της κατάλυσης η οποία έχει πλέον εδραιωθεί ως μία από τις σημαντικότερες μεθοδολογίες για ασύμμετρη και μη ασύμμετρη σύνθεση στην Οργανική Χημεία. Μικρά και αμιγώς οργανικά μόρια, οι αποκαλούμενοι οργανοκαταλύτες, έχουν βρει εφαρμογή σε μία πλη…
The article shows that use of constant dressing in the process of creep-feed grinding of titanium-based alloys allows to reduce significantly force of cutting and to provide grinding without burning. Morphological researches of quality of a grinded surface of an electron microscope of Versa 3D shows a decrease in the…
In this article, we report a novel composite PbSe-graphene nanocomposite synthesis via facile ultrasonic assisted method. The structural and physicochemical properties of PbSe-graphene composite are further characterized by X-ray diffraction, scanning electron microscopy with an energy dispersive X-ray analysis. The p…
