Chemical Reactivity Perspective into the Group 2B Metals Halides
(Amer Chemical Soc, 2016)Chemical reactivity descriptors within the conceptual density functional theory can be used to understand the nature of the interactions between two monomers of the Group 2B metal halides. This information might be valuable ... -
Condensate oscillations oscillations in a Penrose tiling lattice
(Elsevier Science Bv, 2017)We study the dynamics of a Bose-Einstein condensate subject to a particular Penrose tiling lattice. In such a lattice, the potential energy at each site depends on the neighbour sites, accordingly to.the model introduced ... -
Condensation of two-dimensional harmonically confined bosons with Bessel-type interactions
(Amer Physical Soc, 2011)We study the ground-state configurations of few interacting bosons confined in two dimensions by anisotropic harmonic potentials. By means of variational calculations, including correlation effects, we show that the ... -
Dynamical instability of a boson-fermion mixture at low dimensions
(Elsevier Science Bv, 2009)We examine theoretically the dynamical response of a homogeneous mixture of condensed bosons and spin-polarized fermions confined inside a quasi-two-dimensional or a quasi-one-dimensional geometry, considering quasi-thre ... -
Effect of polyvinyl alcohol/chitosan blend ratios on morphological, optical, and thermal properties of electrospun nanofibers
(2019)In this study, the electrospinning method was used to prepare polyvinyl alcohol (PVA)/chitosan (CS) blend nanofibers from their solutions. The effect of blend ratios (PVA/CS: 1%, 3%, 5%, and 7% (w/w)), applied voltage, and ... -
Fabrication and characterization of TiOx based single-cell memristive devices
(Institute of Physics, 2023)Nowadays, remarkable progress has been observed in research into neuromorphic computing systems inspired by the human brain. A memristive device can behaviorally imitate the biological neuronal synapse therefore memristor-based ... -
Fluorescence study of effect of particle size in PS latex/Al2O3 nanocomposite films
(Maney Publishing, 2015)Steady state fluorescence and BioUV-Visible techniques were used to study film formation of polystyrene (PS) latex and Al2O3 composites depending on PS particles size and Al2O3 content. Two film series (SmPS/Al2O3 and ... -
Fluorescence Study of Film Formation from PS Latex-TiO2 Composites: Effects of TiO2 Content, Film Thickness and Particle Size
(Amer Scientific Publishers, 2015)Steady-state fluorescence (SSF) technique in conjunction with UV-visible (UVV) technique, atomic force microscope (AFM) and scanning electron microscope (SEM) is used for studying film formation from TiO2 covered polystyrene ... -
Fluorescence study of film formation from PS/Al2O3 nanocomposites
(Elsevier Science Sa, 2014)Steady state fluorescence (SSF) and UV-vis (UVV) techniques were used to study the film formation behavior of pyrene (P) labeled polystyrene (PS) latex and Al2O3 (PS/Al2O3) composites depending on PS particles size and ... -
High-resolution birefringence investigation of octylcyanobiphenyl (8CB): An upper bound on the discontinuity at the smectic-A to nematic phase transition
(Amer Physical Soc, 2013)We report optical birefringence data by two different methods with high temperature resolution for octylcyanobiphenyl (8CB) near the smectic-A to nematic (Sm-A-N) phase transition temperature T-AN. Within the resolution ... -
