(Wiley-Hindawi, 2018)
1-[(Z)-{(2E)-[(3E)-3-(hydroxyimino)butan-lidene]hydrazinylidene}methyl]naphthalen -2-ol, H2L (3) was synthesized by the agents of 2-hydroxy-1-naphtaldehyde, 2,3-butanedione monoxime and hydrazine in two steps. the structures ...
New ferrocenyl naphthoquinone fused crown ether chemosensors: Highly selective, kinetically and regio controlled colorimetric, beryllium ion recognition
(Elsevier Science Sa, 2018)
New organometallic chemosensors which are based on triad molecules, ferrocenyl naphthoquinone linearly/angularly fused crown ethers (Fc-cnq-1a and Fc-cnq-1b) bearing ferrocene, quinone, and crown ether functional groups ...
Mononuclear Cu(II) complex of an oxime ligand derived from N-Heterocyclic hydrazide: Synthesis, spectroscopy, electrochemistry, DFT calculations and catecholase activity
(Elsevier Science Bv, 2019)
A new oxime derivative N-heterocyclic hydrazide ligand, N'-[(1E,2E)-2-(hydroxyimino)-1-methylpropylidene]-2-[(4-methyl-5-phenyl-4H-1,2,4-triazol-3-1)thio] acetohydrazide (1) and its mono-nuclear copper(II) complex (1a) ...
A new chromenylium-cyanine chemosensor for switch-ON near-infrared copper (II) sensing
(Elsevier, 2020)
A highly selective and sensitive near-IR chemosensor having a chromenylium-cyanine backbone for the detection of Cu2+ in aqueous samples has been designed and synthesized. the sensor has exhibited linear optical response ...
New Chromenylium-cyanine based dual channel chemosensors for copper and hypochlorite sensing
(Elsevier Sci Ltd, 2020)
Based on a change in optical properties of chromenylium-cyanine Schiff base derivatives (5a-c), a series of colorimetric dual sensors have been for the first time designed, synthesized and characterized to monitor Cu2+ and ...
Characterization of microplastic pollution in tadpoles living in small water-bodies from Rize, the northeast of Turkey
(Pergamon-Elsevier Science Ltd, 2020)
Microplastic pollution is a growing problem for Turkey and other countries, but most studies focus on the pollution in oceans and seas. To understand the relationship between microplastics, fresh water, and terrestrial ...
Spatiotemporal distribution of microplastics in true frogs (Ranidae: Pelophylax) populations from Turkiye
(Elsevier, 2023)
Microplastics (MPs), which are of increasing concern in almost all ecosystems, continue to be an environmental threat. In the present study, the presence of MPs is investigated by using the gastrointestinal tracts (GITs) ...
A new activated carbon-supported Pd-ZnO catalyst for Heck Cross-coupling reactions
(Elsevier, 2023)
In this work, to develop catalysts for Heck-type coupling reactions, a hybrid ZnO-Pd nanocatalyst was fabricated on activated carbon sourced from polymer debris. Such techniques as transmission electron microscopy (TEM), ...
Plastic occurrence in fish caught in the highly industrialized Gulf of Izmit (Eastern Sea of Marmara, Turkiye)
(Elsevier, 2023)
Occurrence of micro-(<5 mm) and mesoplastics (5-25 mm) in twelve fish species caught off Gulf of Izmit in the Sea of Marmara was investigated. Plastics were found in the gastrointestinal tracks of all the analysed species: ...
Nano-sized and microporous palladium catalyst supported on modified chitosan/cigarette butt composite for treatment of environmental contaminants
(Elsevier, 2022)
