Direct observation of confined acoustic phonons in the photoluminescence spectra of a single CdSe-CdS-ZnS core-shell-shell nanocrystal
(Amer Physical Soc, College Pk, 2008)
We report on the direct observation of confined acoustic phonons in the photoluminescence spectra of single CdSe-CdS-ZnS nanocrystals, whose ligands were exchanged to poly(ethylene oxide) (PEO) before they were embedded ...
Fermentation of wheat and triticale hydrolysates: A comparative study
(Elsevier Sci Ltd, Oxford, 2009)
In bioethanol production four wheat varieties were investigated: NS 40S, Renesansa, Rapsodija and Dragana, as well as four triticale varieties: Oganj, Jutro, Odisej and NST 21/06. The samples were grinded and mixed with ...
Underpotential deposition of hydrogen on MoPt 4 intermetallic phase in acid solution: Temperature dependence
(Elsevier Ltd, 2004)
Potentiodynamic studies of the underpotential deposition of hydrogen (H upd ) on MoPt 4 electrode in 0.5 mol dm -3 HClO 4 aqueous solution in the range of temperature from 275 to 312 K are made and thermodynamic state ...
Pt/C doped by MoOx as the electrocatalyst for oxygen reduction and methanol oxidation
(Elsevier Science Bv, Amsterdam, 2008)
The oxidation of methanol and reduction of oxygen were studied on MoOx-Pt/C nano-catalysts prepared by the polyole method combined by MoOx post-deposition. The catalysts were characterized by TEM and EDX. The presented ...
Optimization of processing parameters for preparation of LaNiO3 thin films from the citrate precursors
(Elsevier Sci Ltd, Oxford, 2007)
Lanthanum nickel oxide (LaNiO3) is an electrically conductive ceramics, which has a potential use as electrode for ferroelectric thin films, multilayer actuators and many other electronic devices. In this work, LaNiO3 thin ...
Erratum: Effect of temperature on the excess molar volumes of some alcohol + aromatic mixtures and modelling by cubic EOS mixing rules (Fluid Phase Equilibria (2006) 239 (69-82) DOI: 10.1016/j.fluid.2005.10.022)
(Elsevier, 2006)
In Table 2 of the original paper, several typographical errors have occurred in the density and excess molar volume values. In the table below the correct values of ρ and VE are given. It should be mentioned that all ...
Adsorption and corrosion inhibitive properties of some organic molecules on iron electrode in sulfuric acid
(Elsevier, 2002)
Adsorption and corrosion inhibitive properties of three different organic molecules: 2-naphthalenesulfonic acid, 2,7-naphthalenedisulfonic acid and 2-naphthol-3,6-disulfonic acid are investigated on Armco-iron electrode ...
Specificity of the UPD of H to the structure of highly dispersed Pt on carbon support
(Pergamon-Elsevier Science Ltd, Oxford, 2007)
Home-made carbon cryogel synthesized by sol-gel polycondensation and freeze-drying is used as support for preparation of highly dispersed Pt catalyst that is made by a modified polyol synthesis method in an ethylene glycol ...
The effect of agitation intensity on alkali-catalyzed methanolysis of sunflower oil
(Elsevier, 2007)
The sunflower oil methanolysis was studied in a stirred reactor at different agitation speeds. The measurements of drop size, drop size distribution and the conversion degree demonstrate the effects of the agitation speed ...
Thermal properties of textile fabrics made of natural and regenerated cellulose fibers
(Elsevier Sci Ltd, Oxford, 2008)
Cotton (cellulose) and viscose (regenerated cellulose) fibers are commonly applied in clothing textile fabrics. Thanks to the unique hemp (lignocellulose) fibre properties and its ecological benefits (biodegradability), ...
