Synthesis and characterization of Pt nanocatalyst on Ru0.7Ti0.3O2 support as a cathode for fuel cells application
(Elsevier Science Sa, Lausanne, 2015)
Ruthenium oxide/titanium oxide, with a Ru:Ti atomic ratio of 7:3 was synthesized by modified sol-gel procedure and used as a support for platinum nanocatalyst for oxygen reduction reaction. The synthesized materials were ...
Isopiestic determination of the osmotic and activity coefficients of the {yKCl + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2011)
The osmotic coefficients of aqueous mixtures of KCl and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method over the range of ionic strengths from (2.3700 to 11.250) mol . kg(-1) ...
A highly efficient diastereoselective synthesis of alpha-isosalicin by maltase from Saccharomyces cerevisiae
(Elsevier Sci Ltd, Oxford, 2011)
In this report, alpha-isosalicin, a potent anticoagulant and skin whitening agent, was synthesized by a highly efficient chemoselective and diastereoselective reaction, catalyzed by maltase from bakers' yeast (Saccharomyces ...
Mechanism of formation of the honeycomb-like structures by the regime of the reversing current (RC) in the second range
(Elsevier B.V., 2019)
Electrodeposition of copper in the hydrogen co-deposition range by the regime of reversing current (RC) in the second range has been investigated by determination of the average current efficiency for hydrogen evolution ...
Antimicrobial activity of metal oxide nanoparticles supported onto natural clinoptilolite
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The antimicrobial activity of Cu2O, ZnO and NiO nanoparticles supported onto natural clinoptilolite was investigated in the secondary effluent under dark conditions. After 24 h of contact the Cu2O and ZnO nanoparticles ...
A kinetic study of the release of vanillin encapsulated in Carnauba wax microcapsules
(Elsevier Sci Ltd, Oxford, 2012)
Thermal release of vanillin encapsulated in Carnauba wax microcapsules was studied by isothermal thermogravimetric analysis at 443, 453, 473, and 483 K. The thermal analysis data were analyzed kinetically and it was found ...
The friction theory for estimating viscosity of candidate solvents for flue gas desulfurization processes
(Elsevier Science Bv, Amsterdam, 2018)
In this study, applicability of the friction theory for the viscosity estimation of pure substances and binary liquid mixtures, used in regenerative flue gas desulphurization processes, was investigated. Theory was tested ...
