Evaluation of beta-galactosidase from Lactobacillus acidophilus as biocatalyst for galacto-oligosaccharides synthesis: Product structural characterization and enzyme immobilization
(Soc Bioscience Bioengineering Japan, Osaka, 2018)
beta-Galactosidase is an important industrial enzyme that catalyzes reaction of lactose hydrolysis and recently more interesting reaction of transgalactosylation, yielding a highly valuable group of prebiotic compounds ...
Platinum nanocatalysts on metal oxide based supports for low temperature fuel cell applications
(Royal Soc Chemistry, Cambridge, 2016)
In this manuscript a survey of the contemporary research related to platinum nanocatalysts on metal oxide based supports for low temperature fuel cell applications is presented. Different carbon based supports, used as ...
Synthesis and characterization of high-pressure and high-temperature sphene (CaTiSiO5)
(Springer Verlag, 2014)
Sphene (CaTiSiO5), a calcium titanosilicate ceramic has been prepared from a powder mixture of CaCO3, TiO2 and SiO2 using vibro-milling for homogenization and activation of precursors. During the high-pressure and ...
Efficient phytoremediation of uranium mine tailings by tobacco
(Springer-Verlag, 2012)
This investigation shows that tobacco plant roots and leaves accumulate 60 times more uranium than previously reported. Phytoremediation is a convenient technique to clean up polluted soils using herbaceous plants and ...
In vitro cytotoxicity assessment of intelligent acrylate based hydrogels with incorporated copper in wound management
(Elsevier Science Sa, Lausanne, 2016)
In order to evaluate biological response and potential toxicity prior to clinical use as wound dressing materials, three series of hydrogels, based on 2-hydroxyethyl acrylate (HEA) and itaconic acid (IA), unloaded, with ...
Evaluation of novel antiproliferative controlled drug delivery system based on poly(2-hydroxypropyl acrylate/itaconic acid) hydrogels and nickel complex with Oxaprozin
(Elsevier, Amsterdam, 2016)
A series of dual-sensitive poly(2-hydroxypropyl acrylate/itaconic acid) (P(HPA/IA)) hydrogels were synthesized and evaluated as potential highly effective antiproliferative drug delivery system. Investigated hydrophobic ...
Viscoelastic properties of poly(e-caprolactone)/clay nanocomposites in solid and in melt state
(Wiley, Hoboken, 2016)
Viscoelastic properties in solid and in melt state of poly(epsilon-caprolactone), PCL, nanocomposites with organomodified clays (Cloisite30B and Cloisite15A) are thoroughly investigated. Although WAXD is insensitive to the ...
Synthesis of Anatase Nanopowders by Sol-gel Method and Influence of Temperatures of Calcination to Their Photocatalitic Properties
(Međunarodni Institut za nauku o sinterovanju, Beograd, 2015)
The titanium dioxide (TiO2) nanopowders were produced by sol-gel technique from tetrabutyl titanate as a precursor, varying the temperature of calcination (from 500 to 550 degrees C with the step of 10 degrees C). XRPD ...
Determination of kinetic parameters for the hydrogen evolution reaction on the electrodeposited Ni-MoO2 composite coating in alkaline solution
(Elsevier Science Sa, Lausanne, 2012)
As a result of research on the non-noble metal-based composite electrocatalysts for the hydrogen evolution reaction (HER), the Ni-MoO2 composite coating was produced by electrodeposition from an NH4Cl and NiCl2 containing ...
Electrochemical and biocompatibility examinations of high-pressure torsion processed titanium and Ti-13Nb-13Zr alloy
(Wiley, Hoboken, 2018)
The purpose of this study was to estimate the electrochemical behavior and biocompatibility of ultrafine-grained (UFG) commercially pure titanium (CPTi) and Ti-13Nb-13Zr (TNZ) alloy obtained by high-pressure torsion process. ...
