    Abstract The paper describes a technique of CNT synthesis on the fibers of carboxylic fabric. It consists of three operational stages: creation of the experimental facility based on high-temperature quartz flow reactor; ...
  • Mandilara, Aikaterini; Ivić, Zoran; Čevizović, Dalibor; Pržulj, Željko (Chaos, Solitons & Fractals, 2017-12-01)
    Abstract We show that the self-induced transparency of optical phonons may appear in a systems consisting of a two level atoms interacting with elastic waves. The presence of the gap in phonon spectrum substantially enhances ...
  • Asle Zaeem, M.; El Kadiri, H.; Horstemeyer, M.F.; Khafizov, M.; Utegulov, Z. (Current Applied Physics, 2012-03-01)
    Abstract Phase stability, topology and size evolution of precipitates are important factors in determining the mechanical properties of crystalline materials. In this article, the Cahn–Hilliard type of phase-field model ...
  • Kodanova, S.K.; Issanova, M.K.; Amirov, S.M.; Ramazanov, T.S.; Tikhonov, A.; Moldabekov, Zh.A. (Matter and Radiation at Extremes, 2017-09-06)
    Abstract The relaxation of temperature, coupling parameters, the excess part of equation of state, and the correlation energy of the non-isothermal hot dense plasmas are considered on the basis of the method of effective ...
  • Kenzhina, I.; Kulsartov, T.; Chikhray, Y.; Shestakov, V.; Tolebay, A.; Askerbekov, S.; Tazhibayeva, I.; Gordienko, Y.; Ponkratov, Y.; Zaurbekova, Zh.; Mukanova, A. (Materials Today: Proceedings, 2017-01-01)
    Abstract V-Ti-Cr vanadium alloys have many perspective applications, particularly, they are considered as a main structural material of the first wall and blanket of fusion reactor with lithium coolant. Also, they are used ...
  • Canturk, Bilal; Oikonomou, Thomas; Bagci, G. Baris (Annals of Physics, 2017-02-01)
    Abstract Curado et al. (2016) have recently studied the axiomatic structure and the universality of a three-parameter trace-form entropy inspired by the group-theoretical structure. In this work, we study the group-theoretical ...
  • Bubin, Sergiy; Formanek, Martin; Adamowicz, Ludwik (Chemical Physics Letters, 2016-03-01)
    Abstract Complex explicitly correlated one-center all-particle Gaussian functions (CECGs) are tested as basis functions for molecular non-Born–Oppenheimer (non-BO) calculations. The tests concern the complete spectrum of ...
  • Sharkey, Keeper L.; Bubin, Sergiy; Adamowicz, Ludwik (Chemical Physics Letters, 2014-11-25)
    Abstract Accurate variational nonrelativistic quantum-mechanical calculations are performed for the five lowest 1D and four lowest 3D states of the 9Be isotope of the beryllium atom. All-electron explicitly correlated ...
  • Ullrich, B.; Ariza-Flores, D.; Bhowmick, M. (Thin Solid Films, 2014-05-02)
    Abstract While not reported in the literature, by employing highly oriented, semi-insulating, thin-film CdS as test material, we present the observation of the intrinsic photoluminescence Stokes shift in a semiconductor. ...
  • Oikonomou, Thomas; Bagci, G. Baris (Physics Letters A, 2017-01-30)
    Abstract It is well-known that the partition function can consistently be factorized from the canonical equilibrium distribution obtained through the maximization of the Shannon entropy. We show that such a normalized and ...
  • PAPADIMOPOULOS, ATHANASIOS N.; KANTARTZIS, NIKOLAOS V.; TSITSAS, NIKOLAOS L.; VALAGIANNOPOULOS, CONSTANTINOS A. (Optical Society of America, 2017-12-08)
    Color-selective absorption of light is a very significant operation used in numerous applications, from photonic sensing and switching to optical signal modulation and energy harnessing. We demonstrate angle-insensitive ...
  • Malafarina, Daniele (Universe, 2017-05-26)
    In the last four decades, different programs have been carried out aiming at understanding the final fate of gravitational collapse of massive bodies once some prescriptions for the behaviour of gravity in the strong field ...
  • Bambi, Cosimo; Malafarina, Daniele; Modesto, Leonardo (ArXiv, 2016-04-22)
    In a previous paper, we studied the interior solution of a collapsing body in a non-local theory of gravity super-renormalizable at the quantum level. We found that the classical singularity is replaced by a bounce, after ...
  • Yapiyev, Vadim; Sagintayev, Zhanay; Inglezakis, Vassilis J.; Samarkhanov, Kanat; Verhoef, Anne (Water, 2017-10-21)
    Endorheic basins (i.e., land-locked drainage networks) and their lakes can be highly sensitive to variations in climate and adverse anthropogenic activities, such as overexploitation of water resources. In this review ...
  • Ilyas, Batyr; Yang, Jinye; Malafarina, Daniele; Bambi, Cosimo (European Physical Journal C: Particles and Fields, 2017-07-11)
    We study the observational properties of a class of exact solutions of Einstein’s field equations describing stationary, axially symmetric, rigidly rotating dust (i.e. noninteracting particles).We ask the questionwhether ...
  • Good, Michael R.R.; Yelshibekova, Khalykbek; Chin Ong, Yen (ArXiv, 2017-03-03)
    A new solution of a unitary moving mirror is found to produce nite energy and emit thermal radiation despite the absence of an acceleration horizon. In the limit that the mirror approaches the speed of light, the model ...

    The intrinsic photoluminescence Stokes shift, i.e., the energy difference between optical band gap and emission peak, of 350 μm thick semi-insulating GaAs wafers is found to be 4 meV at room temperature. The result is based ...
