Estimation of lipophilicity of n-substituted 2-alkylidene-4-oxothiazolidines by means of reversed-phase thin-layer chromatography
(Taylor & Francis Inc, Philadelphia, 2011)
The chromatographic behavior of 23 new 2-alkylidene-4-oxothiazolidine derivatives was investigated by means of the reversed-phase thin-layer chromatography (RP TLC) on the C18 and CN stationary phases. Binary mixtures of ...
The contributions of high- and low altitude emission sources to the near ground concentrations of air pollutants
(Elsevier Science Inc, New York, 2008)
The scale of transport through the atmosphere depends on the effective height of an emission source, the meteorological conditions and the physico-chemical characteristics of the pollutants. Atmospheric surface temperature ...
Removal of volatile organic compounds from activated carbon by thermal Desorption and catalytic combustion
(Maik Nauka/Interperiodica/Springer, New York, 2007)
The thermal desorption of saturated activated carbon discharged from an industrial adsorber and catalytic oxidation of desorbed products over a Pt/Al2O3 catalyst were investigated. The activated carbon is almost completely ...
Cobalt impregnated pillared montmorillonite in the peroxymonosulfate induced catalytic oxidation of tartrazine
(Springer Netherlands, 2018)
Aluminum pillared montmorillonite impregnated with cobalt (CoAP) was synthesized and characterized using chemical analysis, XRD and N2-physisorption. CoAP was tested as a catalyst in the peroxymonosulfate (Oxone®) induced ...
A second-order nonlinear model of monolayer adsorption in refractometric chemical sensors and biosensors case of equilibrium fluctuations
(Springer, Dordrecht, 2016)
In adsorption-based chemical and biological refractometric sensors the dependence of the refractive index of the sensing area on the number of adsorbed particles is used for detection and quantification of analytes. We ...
Characteristics and catalytic behavior of supported NiMgAg/D catalysts in the partial hydrogenation of soybean oil
(Springer Netherlands, 2015)
Diatomite supported NiMgAg catalysts, NiMgAg/D, were prepared by the precipitation-deposition method followed by drying, reduction and passivation. The preparation of the catalysts was performed with different loading of ...
In situ videometry monitoring of bubble behavior during the electrocatalytic oxygen evolution reaction
(Springer Netherlands, 2015)
Cyclic voltammetry (CV) on rotating Pt disc electrode was used for electrocatalytic oxidation of OH-. Hydroxide ion oxidation is followed by oxygen evolution with gas bubble formation. The image analysis was performed in ...
Field localization control in aperture-based plasmonics by Boolean superposition of primitive forms at deep subwavelength scale
(Springer, Dordrecht, 2016)
Aperture-based nanoplasmonics deals with an important class of structures with subwavelength hole arrays that support surface plasmons polaritons, thus ensuring control over propagation and localization of electromagnetic ...
Parthenolide from the aerial parts of Tanacetum larvatum
(Oxford : Pergamon-Elsevier Science Ltd, 2001)
The genus Tanacetum L. comprises ca 150 species that commonly occur in Europe from the Mediterranean to Persia. Tanacetum larvatum (Gris.) Kanitz, the examination of which is reported, is distributed on elevated rocky ...
Implications of oxidative stress in occupational exposure to lead on a cellular level
(Taylor & Francis Ltd, Abingdon, 2015)
The aim of this study was to determine oxidative alterations leading to cellular dysfunctions in Pb-exposed subjects by evaluating damage to all major classes of biomolecules in the cell, lipid peroxidation, protein and ...
