In recent years, a heated debate on whether the Maxwell's fish eye lens (MFL) can make a perfect imaging with an unlimited resolution has been going on among scholars. We review some recent studies and analyze the resolution of the MFL.
In this research TiB2-TiC Nanocomposite was fabricated by SHS of mechanically milled powders. Ti and B4C as starting materials were milled for 1, 3 and 6 h then pressed to form pellets. Green compacts were placed in a tube furnace which had been preheated to 1200 °C in argon atmosphere, for synthesis. TiC and TiB2 wer…
Transparent and anhydrous proton conducting polymer electrolytes based on polyvinyl alcohol (PVA)/potassium dihydrogen phosphate (KH2PO4) with different concentrations of KDP (φKDP) were prepared by solution casting technique. Ionic conductivity of the polymer electrolytes, studied by the complex impedance method, inc…
Terahertz measurements reveal universality of wideband dielectric panoramas for materials of different classes. A conceptually new approach to their understanding in terms of the dynamical conductivity is proposed.
We present a critical review of recent work on novel liquid crystal cladded plasmonic nano-structures and Blue-Phase liquid crystals containing photosensitive molecules, including tunable metamaterials, reflective or transmission optics, large optical nonlinearities and random lasing action.
In this paper, a low temperature (< 90oC) solution growth technique was used for the fabrication of ZnO nanowires on silicon carbide fibers.The ZnO nanowire grew in a two-step process. The parameters for the growth of nanowires with varying lengths and diameters were optimized. It is shown that ZnO nanowires were grow…
Realization of the method will allow forming a scheme of containment decompression system, adapted to a nuclear power plant conditions, using local steam condensation with the jet sprayer-cooler. Proposition and validation of containment aftercooling method by the passive safety system under continuous blackout, which…
Research on heterogeneous integration system implementation for high-performance and low-power large scale integration (LSI) is in great demand and continues to grow. The co-integration of alternative materials such as Ge and III-V channels on Si substrate is essential in order to fully utilize the conventional Si CMO…
Description of phase behaviour of a highly nonideal system mineral oil + DMF is a rather complex task, because hydrocarbon feed, which has to be separated into aromatic and nonaromatic fractions, consists of large number of compounds that differ significantly in molecular weight and chemical structure. Such a complex…
The Henkel plot and the m plot of a longitudinal barium ferrite hard disk and -Fe2O3 flexible disk were simulated by the improved Preisach-DOK model.The study results show that the barium ferrite exhibit large positive interactions, as shown by large positive in the m plot, and tend to resist demagnetization, leading…
For burning plasma simulation and reactor system analysis on steady-state high beta fusion reactors, TOTAL physics code and PEC engineering code have been developed. From TOTAL analysis, it is clarified that by choosing appropriate external current drive profile, high bootstrap-current fraction is achieved in steady-s…
Four novel gemini quaternary ammonium surfactants containing DSD acid-triazine structure were synthesized using a facile three-step synthetic route , from 4,4'-diamino-2,2'-disulfonic-stilbene (DSD acid), cyanuric chloride and dimethyl dodecylamine. The structures and optical properties of compounds (6a-d) were charac…
This study carried out hydrogen production by reforming of ethanol. In this experiment the parameters were, including ethanol supply rate, O2/EtOH (Oxygen/Ethanol molar ratio), catalysts (Fe, Co, Ni, Pt, Pd, Rh and Ru), and the reforming temperature was provided with heat re-circulation, H2+CO concentration were analy…

Accelerator dominant bottom-up copper superfilling of TSVs was demonstrated. Because of the 100 times large dimensions compared to on-chip interconnections, strong inhibition on the top surface is needed and the superfilling of TSVs are generally achieved by addition of levelers in the plating bath. Recently, we repor…
The use of carbon nanotubes coated by atoms of transition metals to store molecular hydrogen is associated with the problem of the aggregation of these atoms, which leads to the formation of metal clusters. The quantum-chemical simulation of cluster models of the carbon surface of a graphene type with scandium and tit…

It was found that the structural properties with gadolinium (Gd) and europium (Eu) incorporation into nickel (Ni) fully silicided (FUSI) gate electrodes are markedly different and resulted in different degrees of effective work function modulation. It was found that Ni–Gd alloys tend to form stable compounds during si…
Mo 0,60-1,40%. Легирование и высокоэнергетическое плазменное и лазерное воздействие позволяют повышать долговечность литых гусеничных траков в 1,2-1,7 раза, а их эксплуатационную надежность в 1,2-1,3 раза.Caterpillar drives (CD) traditionally find wide application in the undercarriage design of agricultural machinery…
The RE-7075 Al alloy′s hot rolled sheet was studied in this experiment.The microstructure,over-burning temperature,fracture surface and phase were analyzed by modern materials analytical instruments which include OM(optical microscope),DSC(differential scanning calorimetry), SEM(scanning electron microscope) and XRD(X…
