Mesoporous chromium oxide doped palladium catalysis for cyanation reaction of some aryl halides
(Elsevier, 2021)
A Pd/Cr2O3 hybrid catalyst for cyanation reaction of some aryl halides was synthesized and characterized by XRD, SEM/EDS and TEM. The porous structure of the catalyst was also investigated by BET analysis. All XRD ...
The broad-scale microplastic distribution in surface water and sediments along Northeastern Mediterranean shoreline
(Elsevier, 2022)
Plastics manufactured to fulfil the unique demands of civilization accumulate in the sea due to their durability. Microplastics (MP) pose a greater threat than macroplastics as they can easily enter the aquatic environment ...
Plastic occurrence in commercial fish species of the Black Sea
(Central Fisheries Research, 2022)
The occurrence of micro- ( 5 mm), meso- (5-25 mm) and macroplastics ( 25mm) was investigated in seven commercial fish species of the Black Sea. Plastics were found in gastrointestinal track of all species analysed: Engraulis ...
Occurrence of microplastics in herpetological museum collection: Grass snake (Natrix natrix [Linnaeus, 1758]) and dice anake (Natrix tessellata [Laurenti, 1769]) as model organisms
(Springer, 2022)
Microplastics are plastic fragments with a size less than 5 mm in length. In addition to a threat to the marine environments where these are abundantly present, these have also started polluting freshwater ecosystems. ...
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: ...
