Growth, electrical and structural characterization of beta-GaSe thin films
Parlak, Mehmet; Ercelebi, C (Springer Science and Business Media LLC, 2003-04-01)
GaSe thin films were deposited onto the glass substrates kept at 200degrees and 300degreesC by the thermal evaporation of GaSe crystals under the pressure of 10(-5) Torr. X-ray analysis of the films revealed that films grown at 200. C are amorphous in nature while the films grown at 300degreesC are polycrystalline beta-GaSe. The temperature dependent electrical conductivity measurements in the region of 320-100 K for the films grown at 300degreesC showed that the transport mechanisms are the thermionic emis...
Construction of electrochromic devices using thiophene based conducting polymers
COSKUN, YENER; Çırpan, Ali; Toppare, Levent Kamil (Springer Science and Business Media LLC, 2007-01-01)
Dual type polymer electrochromic devices (ECDs) based on poly(terepthalic acid bis-(2-thiophen-3-yl-ethyl)ester) (PTATE), its copolymer with thiophene P(TATE-co-Th) and poly(3,4-ethylenedioxythiophene) (PEDOT) have been constructed. Spectroelectrochemistry, switching ability and stability of the devices were investigated by UV-Vis Spectrophotometer and Cyclic voltammetry. These devices exhibit low switching voltages (between 0.0 V and +1.6 V), short switching times with reasonable switching stability under ...
Effect of MgF2 on hot pressed hydroxylapatite and monoclinic zirconia composites
Evis, Zafer (Springer Science and Business Media LLC, 2007-06-01)
Hydroxylapatite (HA) has been widely used in biomedical applications because of its excellent biocompatibility in the human body. A total of 25 wt% monoclinic (m) zirconia-HA composites (with and without 5 wt% MgF2) were synthesized to investigate their mechanical properties and phase stability. In HA-m-ZrO2 composites, HA and m-ZrO2 reacted to form CaZrO3 when there was no F- present in the composite and M-ZrO2 partially transformed to tetragonal ZrO2. When MgF2 was added into the system, it improved the t...
Interactions at fiber/matrix interface in short fiber reinforced amorphous thermoplastic composites modified with micro- and nano-fillers
Isitman, Nihat Ali; Aykol, Muratahan; Kaynak, Cevdet (Springer Science and Business Media LLC, 2012-01-01)
This study aims at systematically extracting fiber/matrix interfacial strength in short-glass fiber-reinforced polymer composites using an experimental micromechanics approach which employs mechanical properties and residual fiber length distributions to derive the apparent interfacial shear strength. We started from neat high-impact polystyrene matrix short-glass fiber-reinforced composites (HIPS/GF) with varying fiber loading and proceeded toward HIPS/GF hybrid composites containing micro- and nano-filler...
Analysis of tempering treatment on material properties of DIN 41Cr4 and DIN 42CrMo4 steels
Bayrak, Mustafa; Ozturk, Fahrettin; Demirezen, Mehmet; Evis, Zafer (Springer Science and Business Media LLC, 2007-10-01)
DIN 41Cr4 and DIN 42CrMo4 materials have been widely used in automotive driving elements. Although 42CrMo4 is more expensive than 41Cr4, it is more preferable in terms of material properties. In this study, these two materials were heat treated by austenitizing in a continuous furnace at 850 degrees C and quenched in oil at 90 degrees C. After they were tempered at various temperatures, mechanical properties were determined for each tempering temperature. The material properties for both materials were comp...
