Aqueous Pb sorption by synthetic and natural apatite: Kinetics, equilibrium and thermodynamic studies
(Elsevier Science Sa, Lausanne, 2010)
Natural apatites represent a cost effective soil amendment, which can be used for in situ reduction of lead bioavailability and mobility. In our previous work, we selected Lisina apatite (LA) as a promising natural mineral ...
Surface characterisation of PLLA polymer in HAp/PLLA biocomposite material by means of nanoindentation and artificial neural networks
(Taylor & Francis Ltd, Abingdon, 2010)
In this paper, the mechanical properties of polymer matrix phase (modulus of elasticity, yield stress and work hardening rate) have been determined using combined methods such as nanoindentation, finite element modelling ...
Corrosion stability of Zn-Co alloys deposited from baths with high and low Co content - The influence of deposition current density
(Elsevier Science Sa, Lausanne, 2010)
Electrochemically deposited Zn-Co alloys under various deposition conditions were investigated using atomic absorption spectroscopy (AAS) for determination of chemical composition, anodic linear sweep voltammetry (ALSV) ...
Diffusion of drugs from hydrogels and liposomes as drug carriers
(Wiley, Hoboken, 2010)
BACKGROUND: The mass transfer of model drugs Lidocaine hydrochloride and Dihydroquercetin from hydrogels (the usual carriers for topical drugs), and hydrogels containing liposomes, as novel drug vehicles, was studied. ...
Influence of Fe3+ on Photo catalytic Efficiency of Nanopowder-TiO2 and CeO2 - Comparative Study
(ICT Press, Prague, 2010)
Rinsed and thermally treated red mud sorbents for aqueous Ni2+ ions
(Elsevier Science Sa, Lausanne, 2010)
Red mud, an abundant industrial waste from alumina industry, represents a rich source of various metal oxides, mainly of Fe2O3 Al2O3 and SiO2. In this study, the rinsed Bosnian red mud (RBRM) was evaluated as an economical, ...
Nonlinear Frequency Response of Electrochemical Methanol Oxidation Kinetics: A Theoretical Analysis
(Electrochemical Soc Inc, Pennington, 2010)
In this theoretical contribution, nonlinear frequency response analysis was applied for the investigation of electrochemical methanol oxidation. This technique expresses the input-output behavior of any weakly nonlinear ...
Influence of Corona Discharge and Chitosan Surface Treatment on Dyeing Properties of Wool
(John Wiley & Sons Inc, Hoboken, 2010)
In this work, the effects of single and combined corona discharge (CD) and biopolymer chitosan treatment (CS) on the sorption properties and dyeability of woolen fabric were studied. Physical and chemical changes on the ...
A synthesis of N-alkyl and N,N-dialkyl O-ethyl thiocarbamates from diethyl dixanthogenate using different oxidants
(Springer Wien, Wien, 2010)
A novel synthesis of N-alkyl and N,N-dialkyl O-ethyl thiocarbamates from diethyl dixanthogenate and primary and secondary amines, using three oxidizing systems, has been developed on the laboratory scale, and the method ...
Environmental effects of raw pyrolysis gasoline storage and handling: Case study of refinery and petrochemical complex Pancevo, Serbia
(19th International Congress of Chemical and Process Engineering, CHISA 2010 and 7th European Congress of Chemical Engineering, ECCE-7, 2010)
A case study is presented that deals with Refinery and Petrochemical Complex, Pancevo, Serbia, in which handling of raw pyrolysis gasoline (RPG) has two possible pathways, i.e,, by pipelines to nearby refinery or transport ...
