The effect of atmospheric gases on the electrical stability of graphene
(Izmir Institute of Technology, 2017-12)
In this thesis, adsorbate induced variations in the electrical conductivity of graphene layers with two different types of charge carriers are investigated experimentally by using Transient Photocurrent Spectroscopy (TPS) ...
Fine synchronization of the CMS muon drift-tube local trigger using cosmic rays
(IOP Publishing, 2010)
The CMS experiment uses self-triggering arrays of drift tubes in the barrel muon trigger to perform the identification of the correct bunch crossing. The identification is unique only if the trigger chain is correctly ...
Evolution of binaries towards HMXBs and LMXBs
(American Institute of Physics Publising, 2011)
In this study we investigate the evolution of binary systems towards low mass x-ray binaries and high mass x-ray binaries using Eggleton's binary star evolution code. © 2011 American Institute of Physics.
Cu2ZnSnS4-based thin films and solar cells by rapid thermal annealing processing
In this study, kesterite Cu2ZnSnS4 (CZTS) absorber layers were fabricated by DC magnetron sputtering deposition of metallic Cu-Zn-Sn precursors, followed by an annealing treatment in sulfur vapor atmosphere at 600 °C for ...
Statistical approach to tunneling time in attosecond experiments
Tunneling, transport of particles through classically forbidden regions, is a pure quantum phenomenon. It governs numerous phenomena ranging from single-molecule electronics to donor–acceptor transition reactions. The main ...
Atomic-scale understanding of dichlorobenzene-assisted poly 3-hexylthiophene-2,5-diyl nanowire formation mechanism
Low-dimensional Poly 3-hexylthiophene-2,5-diyl (P3HT) structures that serve efficient exciton dissociation in organic solar cells, play a major role in increasing the charge collection, and hence, the efficiency of organic ...
The effects of catalyst pretreatment, growth atmosphere and temperature on carbon nanotube synthesis using Co-Mo/MgO catalyst
The growth of high quality and high yield carbon nanotubes (CNTs) by catalytic chemical vapor deposition (CVD) of CH4 over Co-Mo/MgO catalyst was investigated for different growth temperatures and H2 flow rates. It was ...
Tuning the magnetic anisotropy in single-layer crystal structures
(American Physical Society, 2015-09)
The effect of an applied electric field and the effect of charging are investigated on the magnetic anisotropy (MA) of various stable two-dimensional (2D) crystals such as graphene, FeCl2, graphone, fluorographene, and ...
Synthesis and characterization of cationic lipid coated magnetic nanoparticles using multiple emulsions as microreactors
The aim of this study was to develop a novel iron oxide nanoparticle synthesis method with in-situ surface coating. For this purpose multiple emulsions were used as microreactors for the first time and magnetic iron oxide ...
In situ production of cationic lipid coated magnetic nanoparticles in multiple emulsions for gene delivery
(Marmara University, 2016)
Magnetic nanoparticles are effective delivery systems to target therapeutic genes by the attractive forces of magnetic fields. Curative effects depending on dose of nucleic acids or drugs increased, while cytotoxic effects ...
