Polarized-beam high-energy EDXRF in geological samples
(0-Belirlenecek, 2013)
Certified reference materials (NIST 1645, BCR 143, IAEA 7, BCR 141, NIES-CRM-02, and IAEA 375) were used for determining the performance of a secondary target energy-dispersive X-ray fluorescence (EDXRF) spectrometer, ...
Determination of trace elements in ashes of milk samples by using XRF technique
(Chemical Publishing Co., 2013)
Energy dispersive X-ray fluorescence system has been used to determine the heavy metal ions present in cow's milk. Samples have been collected from farm and markets within the border of Kahramanmaras province, Turkey. An ...
Nitrogen and phosphorus resorption in two wetland macrophytes
(2013)
Nitrogen (N) and phosphorus (P) resorption efficiency (RE) and, resorption proficiency (RP) and functional strategies in Schoenoplectus lacustris subsp. tabernaemontani and Typha latifolia occurring in Cernek Lake and Uzun ...
The effect of external electric field on mass attenuation coefficients of some semiconductor
(Taylor and Francis Inc., 2014)
In this study, we measured the mass attenuation coefficient of n-type GaAs, p-type GaAs, n-type Si and Au/n-Si/n+Si/Al samples with and without external electric field. Samples were set in perpendicular direction to the ...
A psychometric scale for determining university students' attitudes towards the statistics courses they take: Statistical attitude scale (SAS)
(2014)
The aim of this study is to develop a Likert type scale to measure the attitudes of university students towards the statistics course they take. Firstly, first and third grade students from Ondokuz Mayis University Arts ...
Evaluation of phenolic compounds in Tilia rubra Subsp. caucasica by HPLC-UV and HPLC-UV-MS/MS
(Taylor & Francis Ltd., 2014)
Profile of phenolic compounds of Tilia rubra subsp. caucasica was measured by high performance liquid chromatography coupled with ultraviolet and tandem mass spectroscopy. Three different extraction methods (methonolic, ...
Synthesis and fabrication of Mg-doped ZnO-based dye-synthesized solar cells
(Springer, 2014)
Undoped and 2, 4 and 6 at.% Mg-doped ZnO nanorods were successfully deposited on ZnO seeded fluorine tin oxide substrates by a simple chemical bath deposition technique to form a photoanode. It was seen that all the samples ...
An efficient synthesis of some new bisbenzimidazoles via microwave technique
(2014)
2,2’-[1,4 (1,3)-Phenylenedi(methylene)]bis-1 H -benzimidazole derivatives were obtained from the reaction of 1,4- or (1,3)-bisiminoester hydrochloride and o -phenylenediamine derivatives under microwave irradiation. Ester ...
Analysis of one-proton transfer reaction in O 18 + Se 76 collisions at 275 MeV
(American Physical Society, 2024)
Background: A systematic exploration of one-nucleon transfer reactions induced by the (O18,F19) and (O18,O17) reactions on different targets (C12, O16, Al27, Ca40, Ti48, Se76, Sn116) is being performed at the Istituto ...
Synthesis of benzimidazoles containing piperazine ring as potential therapeutic agents against diabetes mellitus and antioxidant activities
(Elsevier, 2024)
We synthesized a novel 6-(4-substitue-piperazin-1-yl)-2-aryl-1H-benzimidazole derivatives starting from 5-(4-substitue-piperazin-1-yl)-2-nitroaniline with different aldehydes. A quick "onepot" nitro reductive cyclization ...
