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 ...
Mechanical properties of friction stir welded St 37 and St 44 steel joints
(Carl Hanser Verlag, 2018)
In this study, the weldability of lower strength St 37 grade steel plate with a higher strength steel plate (i. e., St 44) using the friction stir welding technique has been studied. St 37 grade steel sheets are widely ...
Microstructure and mechanical properties of friction-stir welded St52 steel joints
(Springer, 2018)
The aim of this work is to investigate the mechanical properties and microstructures of friction-stir welded (FSWed) St52 structural steel joints. in this study, St52 steel plates with a thickness of 4 mm were butt-welded ...
An improved sensorless DTC-SVM for three-level inverter-fed permanent magnet synchronous motor drive
(Springer, 2018)
A speed-sensorless control strategy is investigated in a wide speed range based on extended Kalman filter (EKF) and direct torque control with space vector modulation (DTC-SVM) for three-level cascaded H-bridge inverter-fed ...
Bioaccessibility of heavy metals in rapa whelk Rapana venosa (Valenciennes, 1846): Assessing human health risk using an in vitro digestion model
(Taylor & Francis Inc, 2018)
Instead of total metal concentration measurements in seafood, bioaccessibility is a more important parameter for human health risk assessment. Therefore, bioaccessibility of Cd, Cr, Cu, Mn, Ni, Pb, and Zn in the edible ...
