Corrosion stability of polyester coatings on steel pretreated with different iron-phosphate coatings
(Elsevier Science Sa, Lausanne, 2011)
The influence of steel surface pretreatment with different types of iron-phosphate coatings on the corrosion stability and adhesion characteristics of polyester coatings on steel was investigated. The phosphate coating was ...
Removal of lead from water by amino modified multi-walled carbon nanotubes
(Elsevier Science Sa, Lausanne, 2011)
Pristine, oxidized, ethylenediamine, diethylenetriamine and triethylenetetramine modified multi-walled carbon nanotubes (raw-MWCNT, o-MWCNT, e-MWCNT, d-MWCNT and t-MWCNT, respectively) were employed as adsorbents in order ...
Tube for obtaining crystals in a laboratory furnaces
(Maik Nauka/Interperiodica/Springer, New York, 2011)
A model of an air-cooled tube with a number of movable plugs, installed in a laboratory tube furnace is presented. The setup (modular "crystallization shelf-comb") allows easy regulation and simultaneous crystallization ...
The Influence of Surface Treatment by Hydrogenation on the Biocompatibility of Different Hydroxyapatite Materials
(IOP Publishing Ltd, Bristol, 2011)
The influence of hydrogenation on the biocompatibility of different hydroxyapatite (HAP) materials was tested. Materials consisted of pure HAP, HAP substituted with manganese (Mn+2) and with magnesium (Mg+2) - all axially ...

Simultaneous Crystallization Testing in a Laboratory Furnace
(American Laboratory, 2011)
The cooler allows easy regulation of simultaneous crystallization tests of different crystallization parameters and substances, with the purpose of obtaining crystals from a family of newly synthesized compounds with a ...
Local environment of Co2+ ions intercalated in VOx/hexadecylamine nanotubes
(Int Union Crystallography, Chester, 2011)
Experimental determination and modeling of densities and refractive indices of the binary systems alcohol plus dicyclohexylamine at T = (288.15-323.15)K
(Elsevier, Amsterdam, 2011)
The experimental density rho and refractive index n(D) data have been determined for the systems of dicyclohexilamine with 1-propanol, or 1-butanol, or 2-butanol, or 1-pentanol, in the temperature range (288.15, 293.15, ...
