TIMS and MALDI TOF of endohedral Li-n"C-70 (n=1-3) metallofullerenes
(Natl Inst Optoelectronics, Bucharest-Magurele, 2008)
Using the ion implantation technique (introducing negatively charged fullerene into a low temperature lithium plasma column by a strong axial magnetic field) endohedral fullerenes Li"C-70, Li-2"C-70 and Li-3"C-70 were ...
Double-layer bioactive glass coatings obtained by pulsed laser deposition
(Trans Tech Publications Ltd, Durnten-Zurich, 2008)
Pulsed laser deposition was used to obtain functionally graded bioactive glass coatings on titanium substrates. An UV KrF* (lambda=248 nm, tau gt 7 ns) excimer laser was used for the multi-pulse irradiation of the targets. ...
A correlation for heat of vaporization of pure compounds
(Korean Institute Chemical Engineers, Seoul, 2008)
Twenty-seven selected equations were tested on 162 compounds with 1958 calorimetric data for their abilities to reflect the temperature influence on the heat of vaporization of pure compounds. A new equation is recommended ...
Nonlinear FR-ZLC method for investigation of adsorption equilibrium and kinetics
(Springer, New York, 2008)
A new method for investigation of adsorption equilibrium and kinetics, named Nonlinear Frequency Response-Zero Length Column (NFR-ZLC) method, is introduced. It combines the advantages of the Nonlinear FR method (the ...
Cavitation damage of the medium carbon steel: Implementation of image analysis
(Elsevier Science Bv, Amsterdam, 2008)
Cavitation damage of the medium carbon steel was performed using the modified vibratory cavitation test set up. Erosion rates were measured by analytical method. The morphology of damage under cavitation action was determined ...
The effects of hemicelluloses and lignin removal on water uptake behavior of hemp fibers
(Elsevier Sci Ltd, Oxford, 2008)
This study investigated the individual influences of hemicelluloses and lignin removal on the water uptake behavior of hemp fibers. Hemp fibers with different content of either hemicelluloses or lignin were obtained by ...
Membrane interactions of ternary phospholipid/cholesterol bilayers and encapsulation efficiencies of a RIP II protein
(Elsevier Science Bv, Amsterdam, 2008)
Membrane interactions of liposomes of ternary phospholipid/cholesterol bilayers are investigated. These interactions lead to discoidal deformations and regular aggregations and are strongly enhanced by the presence of ...
Extraction of hyperforin and adhyperforin from St. John's Wort (Hypericum perforatum L.) by supercritical carbon dioxide
(Elsevier, Amsterdam, 2008)
St. John's Wort (Hypericum perforatum L.) was extracted with supercritical carbon dioxide (SC CO2) under 10, 15 and 20 MPa and at 313 and 323 K. The influence Of SC CO2 density (400-800 kg/m(3)) was examined with respect ...
Polyaniline as possible anode materials for the lead acid batteries
(Elsevier Science Bv, Amsterdam, 2008)
Electrochemically formed thin film polyaniline (PANI) anode and lead dioxide (PbO2) cathode, obtained from sulfuric acid solution, for potential applications as electrode materials in PANI vertical bar H2SO4 vertical bar ...
The electrochemical behavior of erythromycin A on a gold electrode
(Pergamon-Elsevier Science Ltd, Oxford, 2008)
The reactivity of erythromycin (pure) was investigated on a gold electrode in neutral electrolyte by cyclic voltammetry. The resulting structural changes were observed with HPLC and FTIR spectroscopy by analyzing the bulk ...
