The application of zeolite nanopowder for the construction of the dense composite polymer membranes for carbon dioxide separation
(Inst Materials Physics, Bucharest, 2012)
The main task of the work is to construct the polymeric membrane that could be used for the waste gases treatment. For this purpose, membrane must have high permeability for the carbon dioxide and low permeability of the ...
Dynamic Mechanical Behaviour of Polymer Bonded Nd-Fe-B Composite Materials
(Japan Inst Metals, Sendai, 2012)
Magnetic composite materials with varied content of Nd-Fe-B particles in epoxy matrix are examined from a dynamic mechanical perspective. Structural, viscoelastic and magnetic properties of composites have been observed ...
Crystal structures, magnetic properties and DFT study of cobalt(II) azido complexes with the condensation product of 2-quinolinecarboxaldehyde and Girard's T reagent
(Oxford : Pergamon-Elsevier Science Ltd, 2018)
A tridentate NNO condensation product of 2-quinolinecarboxaldehyde and Girard's T reagent (HLC1) in the presence of azide ions coordinates with cobalt(II) giving mononuclear azido Co(II) complex [CoHL (N-3)(3)](1) as a ...
Quantification of the push-pull effect in 2-alkylidene-4-oxothiazolidines by using NMR spectral data and barriers to rotation around the C=C bond
(Royal Soc Chemistry, Cambridge, 2016)
Information about the strength of donor-acceptor interactions in push-pull alkenes is valuable, as this so-called "push-pull effect'' influences their chemical reactivity and dynamic behaviour. In this paper, we discuss ...
Mono BN-substituted analogues of naphthalene: a theoretical analysis of the effect of BN position on stability, aromaticity and frontier orbital energies
(Royal Soc Chemistry, Cambridge, 2018)
All isomeric BN isosteres of naphthalene have been studied theoretically, at the B3LYP/6-311+G(d,p) level, in order to investigate the effect of the BN position in a molecule on relative stability, aromaticity and frontier ...
Theoretical study of azido gauche effect and its origin
(Royal Soc Chemistry, Cambridge, 2017)
The strength of the azido gauche effect in 1,2-diazidoethane, N-(2-azidoethyl)ethanamide, (protonated) 2-azidoethanamine and (protonated) 2-azidoethanol and its origin were theoretically studied at the MP2/6-311++G(d,p) ...
Unique mononuclear Mn-II complexes of an end-off compartmental Schiff base ligand: experimental and theoretical studies on their bio-relevant catalytic promiscuity
(Royal Soc Chemistry, Cambridge, 2016)
Three new mononuclear manganese(II) complexes, namely [Mn(HL)(2)]center dot 2ClO(4) (1), [Mn(HL)(N(CN)(2)) (H2O)(2)]center dot ClO4 (2) and [Mn(HL)(SCN)(2)] (3) [LH = 4-tert-butyl-2,6-bis-[(2-pyridin-2-yl-ethylimino)-met ...
Effect of the vinyl modification of multi-walled carbon nanotubes on the performances of waste poly(ethylene terephthalate)-based nanocomposites
(Sage Publications Ltd, London, 2017)
Production of high-performance nanocomposite materials obtained from unsaturated polyester resin, based on products of the waste poly(ethylene terephthalate) recycling, and modified multi-walled carbon nanotubes is presented. ...
Structural diversity of isothiocyanato Cd(II) and Zn(II) Girard's T hydrazone complexes in solution and solid state: effect of H-bonding on coordination number and supramolecular assembly of Cd(II) complex in solid state
(Springer/Plenum Publishers, New York, 2018)
The isothiocyanato Zn(II) complex (1) and mixed isothiocyanato/thiocyanato Cd(II) complex (2) with the condensation product of 2-acetylpyridine and trimethylammoniumacetohydrazide chloride (Girard's T reagent) (HLCl) were ...
Fourier-transform infrared spectroscopy analysis of mechanochemical transformation kinetics of sodium carbonate to bicarbonate
(ETRAN Society, 2022)
During mechanical activation, qualitative changes that can produce various phenomena occur in the material. In this study, anhydrous sodium carbonate was mechanically activated for 2, 7, 14, and 28 minutes in a vibro mill ...
