Macroporous and non-porous amino-functionalized glycidyl methacrylate based copolymers for hexavalent chromium sorption
(Chromium: Environmental, Medical and Materials Studies, 2011)
Two porous samples and one non-porous sample of crosslinked poly(glycidyl methacrylate-co-ethylene glycol dimethacrylate) [abbreviated PGME] were synthesized by suspension copolymerization and functionalized by ring-opening ...
Can volcanic dust suspended from surface soil and deserts of Iceland be transferred to central Balkan similarly to African dust (Sahara)?
(Switzerland : Frontiers Media S.A., 2019)
In this work we use chemical fingerprints as characteristics ratios of specific crustal elements Ca/Al, Fe/Al, K/Al, Mg/Al, Mn/Al, Ca/Fe, and Mg/Fe to investigate the long-range transport of volcanic aerosols from Iceland. ...
Degradation of α-nitroso-β-naphthol by UVA-B activated peroxide, persulfate and monopersulfate oxidants in water
(Elsevier, 2019)
Flotation reagents, especially new chelating agents represented by α-nitroso-β-naphthol, are the main components of cobalt mining drainage. This study reports the degradation of α-nitroso-β-naphthol by simulated UVA-B ...
Fluctuations of the number of adsorbed molecules in biosensors due to stochastic adsorption-desorption processes coupled with mass transfer
(Elsevier, 2012)
We derived a simple theory of fluctuations of the equilibrium number of adsorbed molecules in biosensors, caused by the stochastic nature of adsorption-desorption (AD) processes coupled with mass transfer. The two-compartment ...
Optimization of electrolytic process of formation of open and porous copper electrodes by the pulsating current (PC) regime
(Elsevier Science Sa, Lausanne, 2011)
Optimization of process of formation of open and porous copper electrodes, denoted as the honeycomb-like ones, by the regime of pulsating current (PC) is considered. The square-waves PC were consisted of the same amplitude ...
Correlate between morphology of powder particles obtained by the different regimes of electrolysis and the quantity of evolved hydrogen
(Elsevier Science Sa, Lausanne, 2012)
Morphologies of copper powder particles obtained by both potentiostatic and pulsating overpotential (PO) regimes of electrolysis were investigated by the technique of scanning electron microscopy (SEM). Particles of dendritic ...
Solid state and solution structures of Cd(II) complexes with two N-heteroaromatic Schiff bases containing ester groups
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
Two novel cadmium(II) complexes with condensation derivatives of 2-acetylpyridine or 2,6-diacetylpyridine with ethyl hydrazinoacetate hydrochloride were synthesized. X-ray crystal structures of the complexes revealed a ...
Ab initio and density functional study of barrier heights for methyl group torsion and conformational deformability in 1,4,6-trimethylnaphthalene
(Elsevier, 2012)
The results of an investigation into barrier heights for methyl group torsion in the ground electronic state of 1,4,6-trimethylnaphthalene (TMN) is presented. Different approaches (HF, MP2, B3LYP, CCSD(T)) have been employed ...
Degradation of anionic surfactants using the reactor based on dielectric barrier discharge
(Serbian Chemical Soc, Belgrade, 2016)
Two anionic surfactants (sodium lauryl sulfate - SDS and sodium dodecylbenzenesulfonate - SDBS) were treated with dielectric barrier discharge. Loss of surfactant activity, decrease in chemical oxygen demand (COD) and total ...
Surface modification of polyethylene by Ag+ and Au+ ion implantation observed by phase imaging atomic force microscopy
(Elsevier, 2012)
High density polyethylene (HDPE) has been modified by Ag+ and Au+ ion implantation with the energy of 60 and 200 keV, respectively. The doses of implanted silver and gold ions were as follows: 1 x 10(15), 5 x 10(15) and 1 ...
