Investigation of optical parameters of thermally evaporated ZnSe thin films
Gullu, H. H.; Coşkun, Emre; Parlak, Mehmet (2015-04-29)
In this work, zinc selenide (ZnSe) thin films were deposited by thermal evaporation method using pure elemental (Zn and Se) sources. The physical properties of the films have been investigated in terms of the structural and optical characterizations depending on the post-annealing process under nitrogen atmosphere in the temperature between 300 and 500 degrees C for 30 min. The structural and compositional analyses were carried out by means of X-ray diffraction (XRD) and energy dispersive X-ray spectroscopy...
Investigation of the tribological behaviour of electrocodeposited Ni-MoS2 composite coatings
Güler, Ebru Saraloglu; Konca, Erkan; Karakaya, İshak (2017-01-01)
Objective. To discuss a patient with a prenatal diagnosis of unilateral isolated femoral focal deficiency. Case. Antenatal diagnosis of unilateral isolated femoral focal deficiency was made at 20 weeks of gestation. The length of left femur was shorter than the right, and fetal femur length was below the fifth percentile. Proximal femoral focal deficiency was diagnosed. After delivery, the diagnosis was confirmed with skeletal radiographs and magnetic resonance imaging. In prenatal ultrasonographic examinat...
INVESTIGATION OF DESORPTION KINETICS AND EQUILIBRIUM OF AN ANIONIC DYE FROM MAGNETIC POLYMER ADSORBENTS
Akın, Deniz; Yakar, Arzu; Gündüz, Ufuk (2015-09-03)
Dyes, which are used in different industries such as paper, plastics, leather, pharmaceutical, food, cosmetics, textiles, etc., constitute a major class of environmental pollutants. In recent studies, magnetic adsorbents combining magnetic separation technology with the adsorption process has been used to remove dyes from industrial wastewaters. The main advantages of the adsorbents are possible to be easily and simply separated from process media in a short time using the external magnetic field and will b...
INVESTIGATION OF CONDUCTIVITY CHARACTERISTICS OF Zn-In-Se THIN FILMS
Gullu, H. H.; Parlak, Mehmet (World Scientific Pub Co Pte Lt, 2020-01-01)
Zn-In-Se thin films were fabricated on the ultrasonically cleaned glass substrates masked with clover-shaped geometry by thermal evaporation of its elemental sources. Temperature-dependent conductivity characteristics of the films were investigated under dark and illuminated conditions. The semiconductor type of the films was found as n-type by thermal probe test. According to the van der Pauw technique, the dark electrical conductivity analyses showed that the variations of conductivity of unannealed and a...
Investigation of optoelectronic properties of benzotriazole and thiazole bearing conjugated polymers
Ünay, Hakan; Çırpan, Ali; Department of Polymer Science and Technology (2019)
This thesis deals with the design, synthesis and characterization of conjugated polymers P1 and P2 that have potential application in organic solar cell. Polymer design was accomplished by using band gap engineering method. According to that, benzodithiophene (BDT) and silafluorene were chosen as donor groups in P1 and P2 respectively. The acceptor parts were the same for both polymers including benzotriazole (BTZ) and thiazole group. According to electrochemical studies both polymers were having n-dopable ...
