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) ...
Dispersion effect in formic acid oxidation on PtAu/C nanocatalyst prepared by water-in-oil microemulsion method
(Amsterdam : Elsevier Science Bv, 2019)
Low loading PtAu nanoparticles supported on high area carbon were synthesized by water-in-oil microemulsion method and examined for formic acid and methanol oxidation. Prepared catalyst powder was characterized by Xray ...
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 ...
Chemical properties of the cultivated Sideritis raeseri Boiss. & Heldr. subsp raeseri
(Elsevier Sci Ltd, Oxford, 2011)
Phytochemical analyses of the cultivated Sideritis raeseri subsp. raeseri in four different stages of flower development were performed. Traditionally used infusion and decoction were also prepared from aerial parts in ...
Simple avarone mimetics as selective agents against multidrug resistant cancer cells
(Elsevier France-Editions Scientifiques Medicales Elsevier, Paris, 2016)
In this work, synthesis of alkylamino and aralkylamino derivatives of sesquiterpene quinone avarone and its model compound tert-butylquinone was described. For all obtained derivatives biological activity was studied. ...
On the role of working fluid properties in Organic Rankine Cycle performance
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The performance of ORC systems strongly depends on working fluid properties. We explore the relationships between working fluid properties and ORC common economic and thermodynamic performance criteria from a theoretical ...
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 ...
Corrigendum to “Noncovalent bonding: Stacking interactions of chelate rings of transition metal complexes” [Coord. Chem. Rev. 345 (2017) 318–341]
(Elsevier Science Sa, Lausanne, 2018)
Synergistic effect between non-ionic surfactant and halide ions in the forms of inorganic or organic salts for the corrosion inhibition of stainless-steel X4Cr13 in sulphuric acid
(Oxford : Pergamon-Elsevier Science Ltd, 2012)
The inhibition behaviour of the TRITON-X-405 mixed with KBr or C4H12NI in 2.0 M H2SO4 on the ferritic SS was studied using potentiodynamic and EIS measurements. The electrochemical data showed that mixtures used in this ...
Two nitro derivatives of azabenzo[a]pyrene N-oxide: Electronic properties and their relation to mutagenic activity
(Elsevier, 2015)
The equilibrium geometries, relative energies, IR and Raman spectra, vertical ionization potentials (IP), vertical electron affinities (EA), dipole moments (mu), electronic dipole polarizabilities (alpha), and molecular ...
