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 ...
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, ...
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 ...
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) ...
Performance evaluation of multiple adaptive regression splines, teaching-learning based optimization and conventional regression techniques in predicting mechanical properties of impregnated wood
(Springer, 2019)
Understanding the mechanical behaviour of impregnated wood is crucial in making a preliminary decision on the usability of such woods for structural purposes. in this paper, by considering concentration (1, 3 and 5%), ...
Friction stir processing of dual phase steel: Microstructural evolution and mechanical properties
(Elsevier Science Inc, 2019)
The influence of friction stir processing (FSP) on the microstructure and mechanical properties of a DP 600 steel has been studied. the microstructure evolution during the FSP has been characterized using electron back ...
