Seed morphology of epilobium and chamaenerion (Onagraceae) in Turkey
(Magnolia Press, 2017)
Macro- and micro-morphological features of seeds belonging to 26 taxa from Turkey were observed under the light and scanning electron microscopy. Present findings partly agree with segregation of Epilobium and Chamaenerion ...
Design and synthesis of some piperazine hybrid molecules
(Editura Acad Romane, 2017)
In this work, a new series of piperazine hybrid molecules containing coumarin, isatin, salicyl, furane and 1,2,4-triazol-3-thiol moieties was synthesized in good yields. 2-[4-(4-Nitrophenyl)piperazin-1-yl] acetohydrazide ...
Synthesis and characterization of two new hydroxamic acids derivatives and their metal complexes. An investigation on the keto/enol, E/Z and hydroxamate/hydroxirnate forms
(Elsevier Science Bv, 2017)
2-phenylbenzimidazole-N-acetohydroxamic acid (HL1), 2-phenylbenzimidazole-N-butanohydroxamic acid (HL2) and Ni(II), Cu(II), Zn(II) and Cd(II) metal complexes have been synthesized and characterized by elemental analyses, ...
Microstructural and mechanical evolution of a low carbon steel by friction stir processing
(Springer, 2017)
A low carbon steel (Grade A) was subjected to friction stir processing (FSP), and the effect of FSP on the microstructure and mechanical properties was investigated systematically. It was found that two distinct zones ...
Detection of Fe2+ in acetonitrile/water mixture by new 8-hydroxyquinolin based sensor through metal displacement mechanism
(Elsevier Science Bv, 2017)
A 8-hydroxyquinoline-based (8-HQ) fluorescent ligand (2) was designed and synthesized by condensation of pyridine-2-carboxaldehide with 2-(quinolin-8-yloxy)acetohydrazide (1). Fluorometric titrations with various metal ...
Gram (-) microorganisms DNA polymerase inhibition, antibacterial and chemical properties of fruit and leaf extracts of Sorbus acuparia and Sorbus caucasica var. yaltirikii
(Wiley, 2017)
Investigation of novel plant-based agents might provide alternative antibiotics and thus fight antibiotic resistance. Here, we measured the ability of fruit and leaf extracts of Sorbus aucuparia (Sauc) and endemic Sorbus ...
Lasting hepatotoxic effects of prenatal mobile phone exposure
(Taylor & Francis Ltd, 2017)
Objective: in this study, the livers of rats born to mothers exposed to electromagnetic field (EMF) were examined 60 days postpartum for biochemical and histopathological changes.Methods: Pregnant rats were exposed to ...
A new fluorescent "turn-off" coumarin-based chemosensor: Synthesis, structure and Cu-selective fluorescent sensing in water samples
(Springer/Plenum Publishers, 2017)
We report the synthesis and characterization two coumarin-based fluorescence probes, N'-{[7-(diethylamino)-2-oxo-2H-chromen-3-yl]carbonyl}pyridine-3-carbohydrazide (3) and N'-benzoyl-7-(diethylamino)-2-oxo-2H-chromene-3- ...
Structural and electronic properties of MoS2, WS2, and WS2/MoS2 heterostructures encapsulated with hexagonal boron nitride monolayers
(Amer Inst Physics, 2017)
In this study, we investigate the structural and electronic properties of MoS2, WS2, and WS2/MoS2 structures encapsulated within hexagonal boron nitride (h-BN) monolayers with first-principles calculations based on density ...
Synthesis of some novel quinazolin-4(3H)-one hybrid molecules as potent urease inhibitors
(Wiley-V C H Verlag Gmbh, 2018)
A new series of quinazolinone hybrid molecules containing coumarin, furan, 1,2,4-triazole and 1,2,4-thiadiazole rings was designed, synthesized, and screened for their urease inhibition activities. All newly synthesized ...
