Chromium (VI) removal from aqueous solutions using mercaptosilane functionalized sepiolites
(Elsevier, 2011)
Natural and acid-activated sepiolite samples were functionalized with (3-Mercaptopropyl)trimethoxysilane.
By X-ray powder diffraction, Fourier transform infrared spectroscopy, and differential thermal
analysis it was ...
Deoxycholic acid-derived tetraoxane antimalarials and antiproliferatives
(American Chemical Society (ACS), 2007)
The synthesis of deoxycholic acid (DCA)- and cholic acid (CA)-derived mixed tetraoxanes revealed that N-(2-dimethylamino)ethyl derivatives are potent antimalarials in vitro and in vivo. The tetraoxanes presented in this ...
Thermodynamics and Structural Features of the Yeast Saccharomyces cerevisiae External Invertase Isoforms in Guanidinium-chloride Solutions
(American Chemical Society (ACS), 2011)
Recently, four external invertase isoforms (EINV1, EINV2, EINV3, and EINV4) have been isolated from S. cerevisiae. However, there is nothing known about their structural features and thermodynamics of unfolding. Since this ...
Wear and corrosion behaviour of Ti-13Nb-13Zr and Ti-6Al-4V alloys in simulated physiological solution
(Oxford : Pergamon-Elsevier Science Ltd, 2011)
Wear and corrosion behaviour of cold-rolled Ti-13Nb-13Zr alloy, with martensitic microstructure, and Ti-6Al-4V ELI alloy, in martensitic and two-phase (alpha + beta) microstructural conditions, was studied in a Ringer's ...
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 ...
Synthesis and characterization of acid-activated Serbian smectite clays obtained by statistically designed experiments
(Elsevier Science Sa, Lausanne, 2008)
Statistically designed experiments were done to study the recovery of Mg content from natural smectite clays from Serbia by hydrochloric acid leaching. The effects of relevant factors, such as temperature, leaching time, ...
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 ...
Photodegradation of thiacloprid using Fe/TiO2 as a heterogeneous photo-Fenton catalyst
(Elsevier, 2011)
Three Fe/TiO2 photocatalysts with different content of Fe (1.9, 7.2 and 13.9%, w/w) were synthesized by a simple deposition-precipitation method and characterized by XRD, SEM, N-2 physisorption at 77K and Mossbauer ...
Promoting effect of carbon functional groups in methanol oxidation on supported Pt catalyst
(Elsevier Science Inc, New York, 2009)
The contribution of carbon functional groups (CFG) to methanol oxidation at carbon-supported Pt catalysts is studied in this work. Platinum black, attached in a form of a thin layer to electrochemically treated glassy ...
Glassy carbon electrodes: II. Modification by immersion in AgNO 3
(Elsevier, 2001)
The modification of glassy carbon by immersion in AgNO 3 solution was studied by cyclic voltammetry, vacuum techniques (AES and XPS) and STM. The influence of Ag + concentration, time of immersion, the presence of oxygen ...
