Glass transition and polymer dynamics in silver/poly(methyl methacrylate) nanocomposites
(Pergamon-Elsevier Science Ltd, Oxford, 2011)
Dynamic mechanical-thermal analysis (DMTA), differential scanning calorimetry (DSC), thermally stimulated depolarization currents (TSDC) and, mainly, broadband dielectric relaxation spectroscopy (DRS) were employed to ...
Durability of sulfur concrete in various aggressive environments
(Elsevier Sci Ltd, Oxford, 2011)
Durability of sulfur concrete with different fillers, as well as Portland cement concrete, was tested in the solutions of HCl, H(2)SO(4), and NaCl. Regarding mass changes, in the solutions of HCl and H(2)SO(4) sulfur ...
The analysis of simultaneous clove/oregano and clove/thyme supercritical extraction
(Elsevier, Amsterdam, 2011)
The goal of present work was to investigate and explain kinetics and mass transfer phenomena occurring during the SFE from the mixture of two plants with different initial composition. The extractions from pure clove, ...
Investigation of gas transport through porous membranes based on nonlinear frequency response analysis
(Springer, New York, 2011)
Theoretical development of a new experimental method for investigation of mass transport in porous membranes, based on the principle of the modified Wicke-Kallenbach diffusion cell and the nonlinear frequency response ...
Microhardness analysis of thin metallic multilayer composite films on copper substrates
(University of Belgrade, Technical Faculty, Bor, 2011)
Composite systems of alternately electrodeposited nanocrystalline Ni and Cu films on cold-rolled polycrystalline copper substrates were fabricated. Highly-densified parallel interfaces which can give rise to high strength ...
Antimicrobial activity of copper and zinc-doped hydroxyapatite nanopowders
(Elsevier Science Bv, Amsterdam, 2011)
Isolation and Biological Evaluation of Jatrophane Diterpenoids from Euphorbia dendroides
(Amer Chemical Soc, Washington, 2011)
From the Montenegrin spurge Euphorbia dendroides, seven new diterpenoids [jatrophanes (1-6) and a tigliane (7)] were isolated and their structures elucidated by spectroscopic techniques. The biological activity of the new ...
Electrochemical synthesis and characterization of polyaniline thin film and polyaniline powder
(Elsevier Science Sa, Lausanne, 2011)
The polyaniline thin film electrode and powder have been synthesized on graphite electrodes from 0.5 M hydrochloric acid solution under galvanostatic conditions. The water insoluble and acetone soluble polyaniline mass ...
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 ...
Novel properties of PES fabrics modified by corona discharge and colloidal TiO2 nanoparticles
(Wiley, Hoboken, 2011)
The objective of this study was to highlight the potential application of the corona discharge at atmospheric pressure for the surface activation of polyester (PES) fabrics in order to improve the binding efficiency of ...
