Wear and corrosion behaviour of Ti-13Nb-13Zr and Ti-6Al-4V alloys in simulated physiological solution
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Wear and corrosion behaviour of cold-rolled Ti-13Nb-13Zr alloy, with martensitic microstructure, and Ti-6Al-4V ELI alloy, in martensitic and two-phase (alpha + beta) microstructural conditions, was studied in a Ringer's ...
Immobilization of Cell Wall Invertase Modified with Glutaraldehyde for Continuous Production of Invert Sugar
(American Chemical Society (ACS), 2010)
Yeast cell wall invertase (CWI) was modified with dimethyl suberimidate, glutaraldehyde, formaldehyde, and sodium periodate. Retained activity after modification was 45% for CWI modified with formaldehyde, 77% for CWI ...
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 ...
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 ...
Decrease of free fatty acid content in vegetable oil using silica supported ferric sulfate catalyst
(Elsevier Sci Ltd, Oxford, 2012)
A difficulty of biodiesel synthesis based on alkaline catalysts obviously exists if free fatty acids (FFAs) content in vegetable oil is above 0.5 wt.%. In this study, the ferric sulfate supported on silica (Fe-2(SO4)(3)/SiO2) ...
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 ...
Supramolecular Route to Well-Ordered Metal Nanofoams
(American Chemical Society (ACS), 2011)
Metal nanofoams with a porosity above 50% v/v have recently attracted great. Interest In materials science due to their interesting properties.. We.. demonstrate a new straightforward route to prepare such nanofoams using ...
