Structural, photoluminescent and photocatalytic properties of TiO2:Eu3+ coatings formed by plasma electrolytic oxidation
(Elsevier, 2016)
In this paper, we used plasma electrolytic oxidation (PEO) of titanium in water solution containing 10 g/L Na3PO4 center dot 12H(2)O + 2 g/L Eu2O3 powder for preparation of TiO2:Eu3+ coatings. The surfaces of obtained ...
Immobilization of biocatalysts for enzymatic polymerizations: Possibilities, advantages, applications
(Elsevier Sci Ltd, Oxford, 2012)
Biotechnology also holds tremendous opportunities for realizing functional polymeric materials. Biocatalytic pathways to polymeric materials are an emerging research area with not only enormous scientific and technological ...
Shape evolution of carbon supported Pt nanoparticles: From synthesis to application
(Elsevier, 2016)
In this research, a water-in-oil microemulsion method with HCl as a capping agent was applied to synthesize carbon supported Pt catalysts. Varying the concentration of HCl caused changes in the shape of obtained nanoparticles, ...
On the specific surface area of nanoporous materials
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
A proper quantification of the specific surface area of nanoporous materials is necessary for a better understanding of the properties that are affected by the high surface-area-to-volume ratio of nanoporous metals, ...
The formation of tungsten doped Al2O3/ZnO coatings on aluminum by plasma electrolytic oxidation and their application in photocatalysis
(Elsevier, 2016)
Tungsten doped Al2O3 /ZnO coatings are formed by plasma electrolytic oxidation of aluminum substrate in supporting electrolyte (0.1 M boric acid + 0.05 M borax + 2 g/L ZnO) with addition of different concentrations of ...
Supercritical carbon dioxide extraction of antioxidant fractions from selected Lamiaceae herbs and their antioxidant capacity
(Elsevier Sci Ltd, Oxford, 2010)
Antioxidant fractions from four herb spices belonging to the Lamiaceae family: rosemary (Rosmarinus officinalis), sage (Salvia officinalis), thyme (Thymus vulgaris) and hyssop (Hyssop officinalis) were isolated using ...
Photocatalytic properties of TiO2/WO3 coatings formed by plasma electrolytic oxidation of titanium in 12-tungstosilicic acid
(Elsevier, 2012)
In this paper, we have investigated photocatalytic properties of TiO2/WO3 coatings formed by plasma electrolytic oxidation (PEO) of titanium in 12-tungstosilicic acid water solution and compared with photocatalytic activity ...
Purification and characterisation of Saccharomyces cerevisiae external invertase isoforms
(Elsevier Sci Ltd, Oxford, 2010)
Four external invertase isoforms (EINV1, EINV2, EINV3 and EINV4) from Saccharomyces cerevisiae were highly purified by isoelectric precipitation, ethanol precipitation, ion-exchange on QAE-Sephadex and gel filtration using ...
Analysis of the competitive adsorption and mass transfer influence on equilibrium mass fluctuations in affinity-based biosensors
(Elsevier, 2013)
We analyze the fluctuations of the equilibrium adsorbed mass in affinity-based biosensors, considering adsorption-desorption and mass transfer processes of two molecular species which compete for binding to the same probe ...
Porous carbon thin films for electrochemical capacitors
(Oxford : Pergamon-Elsevier Science Ltd, 2013)
Activation effects on carbon films, derived from commercial aromatic polyimide films (Kapton, DuPont), in CO2 atmosphere at 1203 K on capacitance properties were studied. Two thicknesses of polyimide films were used: 7 and ...
