Insight in the regioselective enzymatic transgalactosylation of salicin catalyzed by beta-galactosidase from Aspergillus oryzae
(Elsevier Sci Ltd, Oxford, 2015)
In this study, enzymatic synthesis of galactoside of salicin, compound with potential physiological activity due to structural resemblance with galectin inhibitors, and analgesic and antipyretic properties of salicin, was ...
Preparation of TiO2/carbon nanotubes photocatalysts: The influence of the method of oxidation of the carbon nanotubes on the photocatalytic activity of the nanocomposites
(Elsevier Sci Ltd, Oxford, 2012)
A method for the preparation of efficient TiO2/multi-wall carbon nanotubes nanocomposite photocatalysts by precipitation of anatase TiO2 nanoparticles onto differently oxidized carbon nanotubes is presented. The precursor ...
Evaluation of alginate hydrogels under in vivo-like bioreactor conditions for cartilage tissue engineering
(Springer, Dordrecht, 2010)
Alginate hydrogels in forms of discs and packed beds of microbeads (similar to 800 mu m) were tested in a novel bioreactor at 10% strain using two regimes: at a loading rate of 337.5 mu m/s and at sequential increments of ...
Iron-Modified Sepiolite for Ni2+ Sorption from Aqueous Solution: An Equilibrium, Kinetic, and Thermodynamic Study
(Amer Chemical Soc, Washington, 2010)
Sepiolite was used for the synthesis of the sepiolite-iron oxide system to obtain a sorbent suitable for the removal of Ni2+ from aqueous solution. The modified material, Fe-sepiolite, was characterized by X-ray diffraction ...
Multifunctional PES fabrics modified with colloidal Ag and TiO2 nanoparticles
(Wiley, Hoboken, 2011)
This study is aimed to highlight the possibility of engineering the multifunctional textile nanocomposite material based on the polyester (PES) fabric modified with colloidal Ag and TiO2 nanoparticles (NPs). The effects ...
Exchange-Bias and Grain-Surface Relaxations in Nanostructured NiO/Ni Induced by a Particle Size Reduction
(Amer Chemical Soc, Washington, 2012)
Transition-metal-oxide/transition-metal nanocomposites, such as NiO/Ni, FeO/Fe, and CoO/Co, have been the subject of much recent investigation (i) because of their potential applications and (ii) because they are good model ...
Kinetics of sunflower and used vegetable oil methanolysis catalyzed by CaO·ZnO
(Elsevier Sci Ltd, Oxford, 2013)
The kinetics of heterogeneous methanolysis of sunflower oil and used vegetable oil were studied at different temperatures, ranging from 60 to 96 degrees C using CaO center dot ZnO as catalyst (2 wt% on the basis of oil) ...
Influence of hemicelluloses and lignin content on structure and sorption properties of flax fibers (Linum usitatissimum L.)
(Springer, Dordrecht, 2018)
In this work, alkali and oxidative treatments were employed to obtain flax fibers with different content of hemicelluloses and lignin, in order to study the influence of chemical composition on structure and sorption ...
Encapsulation of resveratrol into Ca-alginate submicron particles
(Elsevier Sci Ltd, Oxford, 2015)
Resveratrol-loaded alginate submicron particles were prepared by emulsification followed by external gelation. Scanning electron microscopy analysis of the air-dried and freeze-dried submicron particles demonstrated their ...
An optimized artificial neural network model for the prediction of rate of hazardous chemical and healthcare waste generation at the national level
(Springer, New York, 2018)
This paper presents a development of general regression neural network (a form of artificial neural network) models for the prediction of annual quantities of hazardous chemical and healthcare waste at the national level. ...
