Structural stability and energetics of uranium microclusters, U-n (n = 3-13, 27-137), have been investigated by molecular-dynamics simulations. An empirical model potential energy function has been parameterised for the uranium element by using the dimer interaction potential energy profile of U-2, which is calculated by relativistic density functional method. Stable structures of the microclusters for n = 3-13 have been determined by molecular-dynamics simulation. It has been found that uranium microclusters prefer to form three-dimensional compact structures. Molecular-dynamics simulations have also been performed for spherical uranium clusters with sizes n = 27-137.

Experimental Insights into the Nanostructure of the Cores of Topological Defects in Liquid Crystals Wang, Xiaoguang; Kim, Young-Ki; Büküşoğlu, Emre; Zhang, Bo; Miller, Daniel S; Abbott, Nicholas L (American Physical Society (APS), 2016-04-04) The nanoscopic structure of the cores of topological defects in anisotropic condensed matter is an unresolved issue, although a number of theoretical predictions have been reported. In the experimental study reported in this Letter, we template the assembly of amphiphilic molecules from the cores of defects in liquid crystals and thereby provide the first experimental evidence that the cores of singular defects that appear optically to be points (with strength m = +1) are nanometer-sized closed-loop, discli...
Theoretical investigation of charge accumulation layer on the Bi-induced InAs(111)-(2 x 2) surface Ozkaya, S.; Usanmaz, D.; ÇAKMAK, MELEK; Alkan, B.; Ellialtıoğlu, Süleyman Şinasi (AIP Publishing, 2014-04-28) Based on pseudopotential method and density functional theory, we have investigated the stability, atomic geometry, and detailed electronic structures for Bi adsorbates on the InAs(111)-(2 x 2) surface with three different sites: (i) T-4 (Bi trimer centered on T-4 site), (ii) H-3 (Bi trimer centered on H-3 site), and (iii) T-4-H-3 (which is formed by trimers with opposite orientations: one centered on a T-4 site and the other on a H-3). Our total energy calculations suggest that adsorption on the T-4-H-3 si...
Photovoltaic Effect and Space Charge Limited Current Analysis in TlGaTe2 Crystals QASRAWI, ATEF FAYEZ HASAN; Yaseen, T. R.; Eghbariy, B.; Hasanlı, Nızamı (Institute of Physics, Polish Academy of Sciences, 2012-07-01) Anisotropic space charge limited current density analysis and photovoltaic effect in TlGaTe2 single crystals has been investigated. It is shown that, above 330 K, the crystal exhibits intrinsic and extrinsic type of conductivity along (c-axis) and perpendicular (a-axis) to the crystal's axis, respectively. The current density (J) is found to be space charge limited. It is proportional to the square and three halves power of voltage (V) along the a- and c-axis, respectively. Along the a-axis and at sufficien...
Molecular-dynamics simulations of carbon nanocage structures: Nanoballs and nanotoroids Erkoç, Şakir; Vural, DC (World Scientific Pub Co Pte Lt, 2001-06-01) The structural stability of carbon nanocages, fullerens and toroids, have been investigated by performing molecular-dynamics computer simulations. The systems considered are C-120 and C-240 in ball and toroidal structures. Calculations have been realized by using an empirical many-body potential energy function for carbon. It has been found that C-120 ball is very unstable, and the other structures are relatively more strong against heat treatment.
Measurement of charm production in neutrino charged-current interactions Kayis-Topaksu, A.; et. al. (IOP Publishing, 2011-09-01) The nuclear emulsion target of the CHORUS detector was exposed to the wide-band neutrino beam of the CERN SPS of 27 GeV average neutrino energy from 1994 to 1997. In total, about 100 000 charged-current (CC) neutrino interactions with at least one identified muon were located in the emulsion target and fully reconstructed, using newly developed automated scanning systems. Charmed particles were searched for by a program recognizing particle decays. The observation of the decay in nuclear emulsion makes it p...
