Synthesis and characterisation of some new hybrid molecules containing thiophene, triazole and coumarin rings under microwave conditions
(Sage Publications Ltd, 2018)
In this work, a new series of N'-{[4-amino-5-oxo-3-(thiophen-2-yl)-4,5-dihydro-1H-1,2,4-triazol-1-yl]acetyl}-2-oxo-2H-1-benzopyran-3-carbohydrazides (thiophene-triazole-coumarin hybrid molecules) was synthesised from the ...
Thermoelectric transport behaviours of n-type Mg-2 (Si,Sn,Ge) quaternary solid solutions
(Keai Publishing Ltd, 2019)
Mg2X (X=Si, Sn, and Ge) based systems have attracted widespread attention owing to their various benefits in thermoelectric applications. in particular, to date, ternary Mg2X based solid solutions have become one of the ...
Microstructure, mechanical properties and formability of friction stir welded dissimilar materials of IF-steel and 6061 Al alloy
(Springer, 2019)
AA 6061 alloy and interstitial-free (IF) steel plates were joined by the friction stir welding (FSW) method, and the microstructure, mechanical properties, and biaxial stretch formability of the friction stir welded (FSWed) ...
Investigation of microstructure and mechanical properties of friction stir welded dissimilar St37/St52 joints
(Iop Publishing Ltd, 2019)
Although friction stir welding (FSW) has widely been applied to aluminum alloys in several industries over the past three decades, it is not yet used in industry for joining of steels. the aim of this study is to characterize ...
Tunable electronic properties of van der Waals heterostructures composed of stanene adsorbed on two-dimensional, graphene-like nitrides
(Amer Inst Physics, 2019)
We investigated the structural stability and electronic properties of stanene/graphene-like nitride (stanene/XN, X = Al, B, and Ga) heterostructures using first-principles calculations. the results reveal that stanene ...
Health risk perspectives of metal(loid) exposure via consumption of striped venus clam (Chamelea gallina Linnaeus, 1758)
(Taylor & Francis Inc, 2019)
The metal(loid)s are mainly transported to the Black Sea via rivers and affect the coastal area where fisheries are intensive. Chamelea gallina (striped venus clam) is the most abundant mollusk species in the Black Sea and ...
Friction stir welding of low-carbon shipbuilding steel plates: Microstructure, mechanical properties, and corrosion behavior
(Springer, 2019)
In this study, low-carbon steel plates (ASTM 131A) used generally in shipbuilding applications were joined by friction stir welding (FSW) using optimum processing parameters. the microstructure, mechanical properties, ...
Artifacts in cranial MRI caused by extracranial foreign bodies and analysis of these foreign bodies
(Wolters Kluwer Medknow Publications, 2019)
Purpose: the purpose of our study was to conduct a chemical analysis of extracranial foreign bodies (FBs) causing artifacts in cranial magnetic resonance imaging (MRI) and to investigate the association between chemical ...
Synthesis and biological evaluation of some succinimide hybrid molecules
(Maik Nauka/Interperiodica/Springer, 2019)
In this study, a new series of succinimide hybrid molecules containing isothiocyanate, coumarin, isatin, and furan moieties was synthesized and screened for alpha-glucosidase and antioxidant activities. Preliminary results ...
