New high-resolution display device for holographic three-dimensional video: principles and simulations
(Bilkent University, 2017-08-03)A new acousto-optical holographic display device, which is expected to solve the display resolution and refresh problems that are common to available holographic displays, is proposed. The device is based on the ... -
Many-body effects in a two-component, one-dimensional electron gas with repulsive, short-range interactions
(Elsevier, 1998-03-09)We investigate the correlation effects in a two-component, one-dimensional electron gas interacting via repulsive δ function interactions. Electron correlations are treated within the approximation scheme of Singwi, Tosi, ... -
Analytic and asymptotic properties of generalized Linnik probability densities
(Elsevier, 1998-01-15)This paper studies the properties of the probability density function pα,ν,n(x) of the n-variate generalized Linnik distribution whose characteristic function φα,ν,n(t) is given by where {norm of matrix}t{norm of matrix} ... -
Recursion operators of some equations of hydrodynamic type
(American Institute of Physics, 2001-03)We give a general method for constructing recursion operators for some equations of hydrodynamic type, admitting a nonstandard Lax representation. We give several examples for N = 2 and N = 3 containing the equations of ... -
Expression of IFITM1 in chronic myeloid leukemia patients
(Elsevier, 2005-03)We investigated the peripheral blood gene expression profile of interferon induced transmembrane protein 1 (IFITM1) in sixty chronic myeloid leukemia (CML) patients classified according to new prognostic score (NPS). IFITM1 ... -
Self-Assembled Peptide Nanofiber Templated One-Dimensional Gold Nanostructures Exhibiting Resistive Switching
(ACS Publications, 2012-10-30)An amyloid-like peptide molecule self-assembling into one-dimensional nanofiber structure in ethanol was designed and synthesized with functional groups that can bind to gold ions. The peptide nanofibers were used as ... -
Photosensitivity Enhancement with TiO2 in Semitransparent Light-Sensitive Skins of Nanocrystal Monolayers
(American Chemical Society, 2014)We propose and demonstrate light-sensitive nanocrystal skins that exhibit broadband sensitivity enhancement based on electron transfer to a thin TiO2 film grown by atomic layer deposition. In these photosensors, which ... -
Post-Treatment od Silicon Nanocrystals Produced by Ultra-Short Pulsed Laser Ablation in Liquid: Toward Blue Luminescent Nanocrystal Generation
(American Chemical Society, 2012-01-11)Blue luminescent colloidal silicon nanocrystals (Si-NCs) were produced in a two-stage process. In the first step, synthesis of Si-NCs was achieved by femtosecond pulsed laser ablation of a silicon wafer, which was immersed ... -
Electrochemically tunable ultrafast optical response of graphene oxide
(AIP Scitation, 2011)We demonstrate reversible and irreversible changes in the ultrafast optical response of multilayer graphene oxide thin films upon electrical and optical stimulus. The reversible effects are due to electrochemical modification ... -
Heparin Mimetic Peptide Nanofibers Promote Angiogenesis
(American Chemical Society, 2011-10-10)New blood vessel formation (angiogenesis) is one of the most important processes required for functional tissue formation. Induction of angiogenesis is usually triggered by growth factors released by cells. Glycosaminoglycans ... -
Release and antibacterial activity of allyl isothiocyanate/-cyclodextrin complex encapsulated in electrospun nanofibers
(Elsevier, 2014-08-01)Allyl isothiocyanate (AITC) is known as an efficient antibacterial agent but it has a very high volatility. Herein, AITC and AITC/-cyclodextrin (CD)-inclusion complex (IC) incorporated in polyvinyl alcohol (PVA) nanofibers ... -
