Effects of Nanoparticle Geometry and Temperature on the Structural Evolution in FeCo Nanoalloys
Yalçın, Mehtap; Mehrabov, Amdulla; Akdeniz, Mahmut Vedat (Institute of Physics, Polish Academy of Sciences, 2014-02-01)
Effects of nanoparticle size (2.0-6.0 rim) and shape (spherical and cubic) on structural characteristic of atomic ordering processes and order-disorder transformation in B2-type ordered equiatomic-FeCo nanoalloys have been studied by combining electronic theory of alloys in the pseudopotential approximation with Ising-type Hamiltonian site exchange Monte Carlo simulation method. Structural evolutions in amorphous nanopaxticles (2-6 nm) of Fe50Co50 alloy have been utilized via molecular dynamic simulations f...
Effects of Montmorillonite Content and Maleic Anhydride Compatibilization on the Mechanical Behavior of Polylactide Nanocomposites
Sarı, Burcu (2016-08-01)
The aim of this study was to investigate the effects of montmorillonite (MMT) type nanoclay content and maleic anhydride (MA) grafted polylactide (PLA) copolymer compatibilization on the mechanical properties of PLA nanocomposites; compounded by twin-screw extrusion melt-mixing followed with injection molding for shaping of bulk specimens. Successively intercalated and exfoliated structures of the nanocomposites were observed by XRD and TEM analysis, including the chemical interactions by FTIR. Mechanical t...
Effects of annealing temperature on the structural and optical properties of ZnO hexagonal pyramids
BACAKSIZ, EMİN; YILMAZ, ŞERİFE; Parlak, Mehmet; Varilci, A.; Altunbas, M. (Elsevier BV, 2009-06-10)
ZnO thin films were deposited on quartz substrate at 550 degrees C by using spray pyrolysis method and subsequently annealed between 600-900 degrees C with a step of 100 degrees C. The characterizations of the structural and optical properties of the films have been carried out by means of X-ray diffraction, scanning electron microscopy (SEM) and optical transmittance measurements. XRD ans SEM images indicated that annealing temperature did not play a great role on the microstructure of ZnO films. ZnO thin ...
Effects of pressure and electric field on the charge transport mechanisms in the silver-modified-zeolite porous microstructure
Koc, Sevgul Ozturk; Koseoglu, Kivilcim; Galioglu, Sezin; Akata Kurç, Burcu; SALAMOV, BAHTİYAR (2016-03-15)
The electrical properties and charge transport mechanisms for nanoporous natural zeolite of clinoptilolite and its silver modified form were studied for the first time in a wide gas pressure range (4-760 Torr) and electric field strength (50-350 kV/cm) at room temperature using two different cell configurations. One of the used cells contained a gas discharge gap, which allowed investigating the electronic conduction route in zeolite cathodes (ZC) as well. The influence of pressure, electric field and cell ...
Effects of production parameters on the structure of resol type phenolic resin/layered silicate nanocomposites
Kaynak, Cevdet (Elsevier BV, 2006-08-01)
Polymer/layered silicate nanocomposites belong to one of the most promising group of materials of the past few decades and most probably for the near future. Following the pioneering works of Toyota Research Group in the 1980s, the interest on these materials increased rapidly and research is now being carried out world wide, using all kinds of polymers as base material.
