Comparisons of surface and optical properties of the heavily carbon-doped GaN nanocrystalline films deposited by thermionic vacuum arc method
(Elsevier Ltd, 2016)In this paper, heavily C-doped GaN samples were deposited on glass and PET substrates by the thermionic vacuum arc (TVA) method, for the first time. Microstructure, surface and optical properties of the carbon-doped GaN ... -
Complexation of metal ions with double-armed diazadithia lariat ether carrying anthracene moieties in acetonitrile-dioxane
(2010)A new 14-membered crown ether with nitrogen-sulfur donor atom carrying two anthryl groups was designed and synthesized by the reaction of the corresponding macrocyclic compound and 9-(chloromethyl) anthracene. The influence ... -
Complexation of metal ions with the novel azathia crown ethers carrying anthracene pendant in acetonitrile-dichloromethane
(2010)A series of crown ethers carrying an anthracene group with nitrogen-sulfur donor atom, which differ in having three, four and five sulfur atoms in the macrocycle was designed and synthesized by the reaction of the corresponding ... -
Complexation of metal ions with the novel diazadithia crown ether carrying two anthryl pendants in acetonitrile-tetrahydrofuran
(2010)A new crown ether carrying two anthryl groups with nitrogen-sulfur donor atom was designed and synthesized by the reaction of the corresponding macrocyclic compound and 9-chloromethyl anthracene. The influence of metal ... -
Complexation of metal ions with the novel diazadithia crown ethers carrying two pyrene pendants in acetonitrile-tetrahydrofuran
(2010)Two crown ethers carrying pyrene side arms with nitrogen-sulfur donor atom were designed and synthesized by the reaction of the corresponding macrocyclic compounds and 1-bromomethyl-pyrene. The influence of metal cations ... -
Concentrating photovoltaic thermal (CPVT) collectors and systems: Theory, performance assessment and applications
(Elsevier Ltd, 2018)Concentrating photovoltaic thermal (CPVT) collectors and systems are very popular in both domestic and industrial solar energy applications. CPVT collectors provides incomparably greater thermal and electrical outputs ... -
Concept-teaching practices in social studies classrooms: Teacher support for enhancing the development of students’ vocabulary
(Edam, 2017)The purpose of this study is to describe social studies teachers’ perceptions related to their practices in teaching concepts within the context of social studies instruction in order to enhance students’ vocabulary ... -
Concretes with synthetic aggregates for sustainability
(Elsevier Ltd, 2017)We have used waste marble aggregates, marble dust and fly ash from thermic power plants as fillers in concretes for replacing natural aggregates. We have used two different kinds of cements. After curing, we have determined ... -
Conformational and spectroscopic behaviors of 2,4-xylyl isothiocyanate
(Elsevier, 2015)This study aims to identify the conformational and spectroscopic characteristics of 2,4-xylyl isothiocyanate (C<inf>9</inf>H<inf>9</inf>NS) compound via experimental and computational methods. To accomplish this, density ... -
Conjugated polythiophene/Ni doped ZnO hetero bilayer nanocomposite thin films: Its structural, optical and photoluminescence properties
(Elsevier Ltd, 2018)In this study, synthesis and characterization of plasma polymerized Thiophene/ Nickel doped Zinc Oxide (PTNZO) bilayer nanocomposite films were carried out. Nickel doped zinc oxide (NZO) thin films were obtained by magnetron ... -
Context based learning effects on achievement and scientifc process skills in biology teaching
(2013)Bu çalışmanın amacı yaşam temelli öğrenme yaklaşımının biyoloji öğretiminde öğrenci başarıları ve bilimsel süreç becerileri üzerine etkilerini araştırmaktır. Bu amaç için ön-son test kontrol gruplu yarı deneysel desen ... -
Continuous and discontinuous contact problem of a functionally graded layer resting on a rigid foundation
(Springer-Verlag Wien, 2017)In this study, the continuous and discontinuous contact problem of a functionally graded (FG) layer resting on a rigid foundation is considered. The top of the FG layer is subjected to normal tractions over a finite segment. ... -
Continuous contact problem for two elastic layers resting on an elastic half-infinite plane
(Mathematical Sciences Publishers, 2014)The continuous contact problem for two elastic layers resting on an elastic half-infinite plane and loaded by means of a rigid stamp is presented. The elastic layers have different heights and elastic constants. An external ... -
Continuous contact problem of a functionally graded layer resting on an elastic half-plane
(Polish Academy of Sciences, 2017)In this study, the continuous contact problem of a functionally graded layer resting on an elastic half-plane and loaded by a rigid rectangular stamp is examined. The problem is solved assuming that the functionally graded ... -
Contribution of the cogeneration systems to environment and sustainability
(Springer Verlag, 2018)The kind of energy that buildings need changes, like heating energy, cooling energy, electrical energy, and thermal energy for hot top water. Usually, the processes or systems that produce thermal energy emit pollutants ... -
Correlation between the DNA methylation and gene expression of IGFBP5 in breast cancer
(IOS Press, 2016)BACKGROUND: The insulin-like growth factor binding protein5 (IGFBP5) is often dysregulated in human cancers and considered neither a tumor suppressor nor an oncogene. OBJECTIVE: We aim to examine the reason of the changeable ... -
Correlation coefficient of single-valued neutrosophic hesitant fuzzy sets and its applications in decision making
(Springer London, 2017)As a combination of the hesitant fuzzy set (HFS) and the single-valued neutrosophic set (SVNS), the single-valued neutrosophic hesitant fuzzy set (SVNHFS) is an important concept to handle uncertain and vague information ... -
Cross-entropy measure on interval neutrosophic sets and its applications in multicriteria decision making
(Springer London, 2017)The neutrosophic set model is an important tool for dealing with real scientific and engineering applications because it can handle not only incomplete information but also the inconsistent information and indeterminate ... -
