Bu calismada, elektrokimyasal yontemle TiO2 katkili elmas-benzeri karbon (EBK) nanokompozit film uretimi icin yeni metot onerilmistir. TiO2 katkili EBK nanokompozit film uretimi icin titanyum metali once hidrojen peroksit (H2O2) icerisinde cozundu. Daha sonra bu cozelti ve metanol, hacimce 1:200 oraninda karistirilarak iki elektrotlu hucrede elektroliz edildi. Elde edilen film taramali elektron mikroskobu (SEM), Raman spektroskopisi, X-isinlari fotoelektron spektroskopisi (XPS) ve X-isinlari kirinimi (XRD) ile karakterize edildi. SEM fotografi, filmin homojen fakat gozenekli bir yuzeye sahip oldugunu gostermistir. Raman spektroskopisi, TiO2 katkisinin sp3 karbon baglarina neden oldugunu ortaya koymustur. XPS analizi, karbonun sp3 bagli oldugunu ve filmin TiO2 katkili oldugunu gostermistir. XRD spektrumunda, hekzagonal karbon yapiya ait pikler gozlenmistir. Elde edilen bulgular, yuksek miktarda sp3 baglari iceren EBK nanokompozit filmin, elektrokimyasal yontemle basarili bir sekilde uretilebilecegini gostermektedir.

Recently, Akin, Dundar and Ulusu defined and studied asymptotically lacunary I-invariant statistical equivalence for sequences of sets defined by a modulus function [N. P. Akin, E. Dundar and U.Ulusu, Asymptotically Lacunary I-Invariant Statistical Equivalence of Sequences of Set Defined By A Modulus Function, Sakarya Univ. J. Sci. 22(6) (2018)]. In this study, first, we present the concepts of strongly asymptotically I_2^σθ-equivalence, f-asymptotically I_2^σθ-equivalence, strongly f-asymptotically I_2^σθ-equivalence for double sequences of sets. Then, we investigate some properties and relationships among this new concepts. After, we present asymptotically I_2^σθ-statistical equivalence for double sequences of sets. Also we investigate relationships between asymptotically I_2^σθ-statistical equivalence and strongly f-asymptotically I_2^σθ-equivalence.
最近，Akin, Dundar和Ulusu定义并研究了由模函数定义的集合序列的渐近无i不变统计等价。P. Akin, E. Dundar, U.Ulusu，模函数定义的集合序列的渐近无i不变统计等价，上海大学学报(自然科学版)，22(6)(2018)。本文首先给出了集的二重序列的强渐近I_2^σθ-等价、f-渐近I_2^σθ-等价、强f-渐近I_2^σθ-等价的概念。然后，我们研究了这些新概念之间的一些性质和关系。然后，我们给出了集的二重序列的渐近I_2^σθ-统计等价性。研究了渐近I_2^σθ-统计等价与强f-渐近I_2^σθ-等价之间的关系。

The transformed rational function method can be considered as unification of the tanh type methods, the homogeneous balance method, the mapping method, the exp-function method and the F-expansion type methods. In this paper, we present complexiton solutions of (3+1) dimensional Korteweg-de Vries (KdV) equation and a new (3+1) dimensional generalized Kadomtsev-Petviashvili equation by using extended transformed rational function method which provides very useful and effective way to obtain complexiton solutions of nonlinear evolution equations.

(E)-4-bromo-5-methoxy-2-((o-tolylimino)methyl)phenol was investigated by experimental and theoretical methodologies. The solid state molecular structure was determined by X-ray diffraction method. All theoretical calculations were performed by density functional theory (DFT) method by using B3LYP/6-31G(d,p) basis set. The titled compound showed the preference of enol form, as supported by X-ray diffraction method. The geometric and molecular properties were compaired for both enol-imine and keto-amine forms for title compound. Stability of the molecule arises from hyperconjugative interactions, charge delocalization and intramolecular hydrogen bond has been analyzed using natural bond orbital (NBO) analysis. Mulliken population method and natural population analysis (NPA) have been studied. Also, condensed Fukui function and relative nucleophilicity indices calculated from charges obtained with orbital charge calculation methods (NPA). Molecular electrostatic potential (MEP) and non linear optical (NLO) properties are also examined.
