Exchange-Bias and Grain-Surface Relaxations in Nanostructured NiO/Ni Induced by a Particle Size Reduction
(Amer Chemical Soc, Washington, 2012)
Transition-metal-oxide/transition-metal nanocomposites, such as NiO/Ni, FeO/Fe, and CoO/Co, have been the subject of much recent investigation (i) because of their potential applications and (ii) because they are good model ...
Preparation of TiO2/carbon nanotubes photocatalysts: The influence of the method of oxidation of the carbon nanotubes on the photocatalytic activity of the nanocomposites
(Elsevier Sci Ltd, Oxford, 2012)
A method for the preparation of efficient TiO2/multi-wall carbon nanotubes nanocomposite photocatalysts by precipitation of anatase TiO2 nanoparticles onto differently oxidized carbon nanotubes is presented. The precursor ...
Influence of Cr, Mn and Mo Addition on Structure and Properties of V Microalloyed Medium Carbon Steels
(Journal Mater Sci Technol, Shenyang, 2012)
The effect of austenitizing temperature and Cr, Mo and Mn addition on microstructure and mechanical properties of V microalloyed medium carbon steel has been studied by means of metallography and mechanical testing. The ...
The Viscoelastic Properties of Modified Thermoplastic Impregnated Multiaxial Aramid Fabrics
(Wiley, Hoboken, 2012)
This study reports the manufacture of new fabric forms from the preparation of hybrid laminated multiaxial composites with enhanced thermo-mechanical properties. Thermal and dynamic mechanical analysis of polymer matrix ...
Radiation-induced synthesis and swelling properties of p(2-hydroxyethyl methacrylate/itaconic acid/oligo (ethylene glycol) acrylate) terpolymeric hydrogels
(Radiation Physics and Chemistry, 2012)
Since it is presumed that by incorporation of pH-responsive (IA) and temperature-responsive (OEGA) co-monomers, it is possible to prepare P(HEMA/IA/OEGA) hydrogels with dual (pH and thermo) responsiveness, the main purpose ...
Versatile use of biomimetic bioreactors for functional evaluation of nanocomposite alginate based hydrogels
(Wiley-Blackwell, Hoboken, 2012)
Antimicrobial activity of metal oxide nanoparticles supported onto natural clinoptilolite
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The antimicrobial activity of Cu2O, ZnO and NiO nanoparticles supported onto natural clinoptilolite was investigated in the secondary effluent under dark conditions. After 24 h of contact the Cu2O and ZnO nanoparticles ...
A kinetic study of the release of vanillin encapsulated in Carnauba wax microcapsules
(Elsevier Sci Ltd, Oxford, 2012)
Thermal release of vanillin encapsulated in Carnauba wax microcapsules was studied by isothermal thermogravimetric analysis at 443, 453, 473, and 483 K. The thermal analysis data were analyzed kinetically and it was found ...
Isopiestic determination of the osmotic and activity coefficients of the {yKNO(3) + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2012)
The osmotic coefficients of aqueous mixtures of KNO3 and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method at KNO3 ionic strength fractions y = (0.20581, 0.43631, 0.61099, and ...
Surfactant-modified clinoptilolite as a salicylate carrier, salicylate kinetic release and its antibacterial activity
(Elsevier Science Bv, Amsterdam, 2012)
The cationic surfactant benzalkonium chloride (BC) was used for modification of the natural clinoptilolite surface in order to prepare a suitable carrier for the salicylate anion. The salicylate-containing clinoptilolite ...
