Applications and impact of nanocellulose based adsorbents
(Springer, 2020)Abstract Efficient separation and removal is necessary in applications ranging from environmental remediation to the food sector. A well-designed adsorption system should meet the demands for high efficiency in a cost and ... -
Approximation by positive linear operators in modular spaces by power series method
(Birkhauser Verlag AG, 2017)In the present paper, we study the problem of approximation to a function by means of positive linear operators in modular spaces in the sense of power series method. Indeed, in order to get stronger results than the ... -
Approximation to derivatives of functions by linear operators acting on weighted spaces by power series method
(Springer New York LLC, 2016)In this chapter, using power series method we study some Korovkin type approximation theorems which deal with the problem of approximating a function by means of a sequence of linear operators acting on weighted spaces. © ... -
Arbitrarily long factorizations in mapping class groups
(Oxford University Press, 2015)Abstract. On a compact oriented surface of genus g with n ≥ 1 boundary components, δ1, δ2, . . . , δn, we consider positive factorizations of the boundary multitwist tδ1 tδ2 · · ·tδn , where tδi is the positive Dehn twist ... -
The Arzelà-Ascoli theorem by means of ideal convergence
(De Gruyter, 2018)In this paper, using the concept of ideal convergence, which extends the idea of ordinary convergence and statistical convergence, we are concerned with the I-uniform convergence and the I-pointwise convergence of sequences ... -
Aspects of thermal martensite in a FeNiMnCo alloy
(2010)Thermal martensite characteristics in Fe-29%Ni-2%Mn-2%Co alloy were investigated with scanning electron microscopy (SEM) and Mössbauer spectroscopy characterization techniques. SEM observations obviously revealed the lath ... -
Assessment of ecological status and water quality by using some trophic indices in a Dam Lake
(Scibulcom Ltd., 2016)The composition and seasonal variations of benthic diatoms of Yedikir Dam Lake were studied using samples collected from two stations between November 2004 and April 2006. The diatom communities were diverse: 81 taxa were ... -

Attitudes, self-efficacy and science processing skills of teaching certificate master's program (OFMAE) students
(2010)Problem Statement: The present research investigated attitudes toward science teaching, science teaching self-efficacy, and science processing skills of 77 students attending a teaching certificate master's program on ... -
Azo-methoxy-calix[4]arene complexes with metal cations for chemical sensor applications: Characterization, QTAIM analyses and dispersion-corrected DFT- computations
(Pergamon-Elsevier Science Ltd, 2022)In this work, the structures, quantum chemical descriptors, morphologic characterization of the azomethoxy-calix[4]arene were investigated. The analyses and interpretation of the theoretical and the experimental IR ... -
Benzodithiophene and benzotriazole bearing conjugated polymers for electrochromic and organic solar cell applications
(Electrochemical Society Inc., 2017)Herein, alternating donor-acceptor type benzodithiophene and benzotriazole bearing copolymers were synthesized and thieno[3,2-b]thiophene and furan units were incorporated as ?-bridges. The application of these polymers ... -
Benzotriazole and benzodithiophene containing medium band gap polymer for bulk heterojunction polymer solar cell applications
(John Wiley and Sons Inc., 2014)An alternating donor‐acceptor copolymer based on a benzotriazole and benzodithiophene was synthesized and selenophene was incorporated as π‐bridge. The photovoltaic and optical properties of polymer were studied. The ... -
Benzotriazole and benzothiadiazole containing conjugated copolymers for organic solar cell applications

Big cats from prehistoric İzmir: A paleontological approach to zooarchaeological material
(ELSEVIER, 2023)The species Panthera has always held special significance in the archaeological record because of its scarcity and symbolic meaning in ancient societies. In Anatolian archaeology, these animals are present in assemblages ... -
Bioactive glasses prepared from organic-mediated B-O-P bonded materials
(Elsevier, 2014)In this study, we introduce an alternative route for the synthesis of bioactive borate-phosphate glasses. Glasses with nominal compositions of xNa2O·yB2O3·zP2O 5 (x = 1, 2; y = 1/2; z = 1/2, 3/2) were obtained via melt-quench ... -
