Evaluation of properties of sputtered Ni/Cu films with different thicknesses of the Cu layer
(Elsevier Science SA, 2021)In this study, Ni/Cu thin films with Cu layer thicknesses varying from 200 nm to absence of Cu (0 nm) were produced by using a magnetron sputtering technique in order to investigate their structural and magnetic properties. ... -
Characterisation of dark matter in direct detection experiments: Singlino versus Higgsino
(Elsevier, 2021)We show how the material used in direct detection experiments of Dark Matter (DM), in the presence of a signal of it, can afford one with the possibility of extracting the nature of the underlying candidate. We do so for ... -
Species composition of benthic fish fauna in the Sea of Marmara, Turkey
(Wiley, 2021)In order to determine the present benthic fish fauna in the Sea of Marmara, sampling was conducted at a total of 10 stations for 2 weeks in August 2009, using a commercial twin beam trawling vessel with 18 and 36 mm stretched ... -
Essential oil chemical composition, antimicrobial, anticancer, and antioxidant effects of Thymus convolutus Klokov in Turkey
(Walter De Gruyter GMBH, 2021)In this study, the chemical composition, antimicrobial, antioxidant, and anticancer effects of Thymus convolutus Klokov oil and its main compound camphor were investigated. The oil was isolated from T. convolutus using ... -
Asymptotically good towers of function fields with small p-rank
(Academic Press Inc Elsevier Science, 2021)Over any quadratic finite field we construct function fields of large genus that have simultaneously many rational places, small p-rank, and many automorphisms. -
Microwave-assisted cross-coupling synthesis of aryl functionalized MWCNTs and investigation of hydrogen storage properties
(Taylor & Francis Inc, 2021)In recent years, nanostructures have attracted the attention of many scientists due to their unique properties. Many properties of nanostructures can be improved by changing the surface. For this purpose, multi-walled ... -
Dielectric measurements on stearic acid/eicosylamine alternate layer Langmuir-Blodgett films incorporating CdS nanoparticles
(Springer, 2021)Langmuir-Blodgett deposition of 16 and 15 monolayers of stearic acid/eicosylamine has been accomplished on ultrasonically cleaned aluminized quartz substrate with 50 nm thick evaporated aluminium electrodes. Alternating ... -
