Inhibition of Na+/K+-ATPase and cytotoxicity of a few selected gold(III) complexes
(Journal of Inorganic Biochemistry, 2014)
Na+/K+-ATPase is in charge of maintaining the ionic and osmotic intracellular balance by using ATP as an energy source to drive excess Na+ ions out of the cell in exchange for K+ ions. We explored whether three representative ...
Radiative heat exchange inside the pulverized lignite fired furnace for the gray radiative properties with thermal equilibrium between phases
(International Journal of Thermal Sciences, 2014)
The objective of the research was to find if an agreement of the results of a numerical investigation with experimental data could be achieved considering the two-phase medium in thermal equilibrium. Influence of the gray ...
Measurement of Th-232(n,5n gamma) cross sections from 29 MeV to 42 MeV
(European Physical Journal A. Hadrons and Nuclei, 2014)
The excitation function of the reaction (232) Th(n, 5n gamma)(228) Th from 29 to 42 MeV has been measured for the first time at the quasi-monoenergetic neutron beam of the UCL cyclotron CYCLONE employing the Li-7(p,n) ...
Synthesis of pure and La-doped anatase nanopowders by sol-gel and hydrothermal methods and their efficiency in photocatalytic degradation of alprazolam
(Ceramics International, 2014)
Pure and La3+ doped titanium dioxide (TiO2) nanopowders were obtained by sol gel and hydrothermal methods. A precursor was titanium tetrachloride and concentrations of dopants were 0.5 and 1.0 mol%. Procedures of both ...
Oxidation of chlorpyrifos, azinphos-methyl and phorate by myeloperoxidase
(Pesticide Biochemistry and Physiology, 2011)
The present paper deals with the investigations of optimal conditions for the myeloperoxidase (MPO) mediated oxidation of chlorpyrifos, azinphos-methyl and phorate, organophosphorous pesticides (OPs) containing phosphorothionate ...
Effect of processing parameters on structural, morphological and optical Y2O3:Yb3+/Ho3+ powders characteristics
(Advanced Powder Technology, 2014)
Rod-like and flake-like up-converting Y2O3:Yb3+/Ho3+ particles which are composed of nanoparticles with size less than 100 nm, are prepared by a simple hydrothermal processing at 473 K (3 h) followed by additional thermal ...
Synthesis and characterization of high-pressure and high-temperature sphene (CaTiSiO5)
(Physics and Chemistry of Minerals, 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 ...
DEM/CFD analysis of granular flow in static mixers
(Powder Technology, 2014)
Mixing of powders, particles and/or granules obtains an economic importance in various technologies, and in the food, pharmaceutical and chemical industries. In many cases, the mixing process greatly influences the quality ...
Nanocrystalline CeO2-delta as Effective Adsorbent of Azo Dyes
(Langmuir, 2014)
Ultrafine CeO2-delta nanopowder, prepared by a simple and cost-effective self-propagating room temperature synthesis method (SPRT), showed high adsorption capability for removal of different azo dyes. Batch type of adsorption ...
Theory of photoacoustic effect in media with thermal memory
(Journal of Applied Physics, 2014)
This paper presents a model for indirect photoacoustic response that includes thermal memory effects. At low frequencies, the model reduces to the well-known thermal piston model of photoacoustic response given by Rosencweig ...
