Studies of the Thermal and Mechanical Properties of Poly(urethane-siloxane)s Cross-Linked by Hyperbranched Polyesters
(American Chemical Society (ACS), 2012)
Polyurethane networks based on Boltorn hyperbranched polyesters (HBPs) of different pseudogenerations as cross-linkers, alpha,omega-dihydroxy(ethylene oxide-poly(dimethylsiloxane)-ethylene oxide) (EO-PDMS-EO) and ...
Intrinsic Potential-Dependent Performances of a Sol-Gel-Prepared Electrocatalytic IrO2-TiO2 Coating of Dimensionally Stable Anodes
(Springer, New York, 2012)
The electrochemical properties of a sol-gel-prepared IrO2-TiO2 coating on Ti were investigated from the standpoint of the charging/discharging behavior in 1.0A degrees mol dm(-3) H2SO4 and in 0.50A degrees mol dm(-3) NaCl, ...
Wash-dry cycle induced changes in low-ordered parts of regenerated cellulosic fibers
(Wiley-Blackwell, Hoboken, 2012)
Three regenerated cellulosic fiber types: lyocell, viscose, and modal were subjected to repetitive wetdry treatments. Simulated treatments showed reorganization of the internal fiber structure which could be determined by ...
Encapsulation of Thymus serpyllum L. aqueous extract in chitosan and alginate-chitosan microbeads

Kinetics and mechanism of degradation of Co(II)-N-benzyloxycarbonylglycinato complex
(Springer, Dordrecht, 2012)
The kinetics of multi-step thermal degradation of Co(II) complex with N-benzyloxycarbonyl glycinato ligand [Co(N-Boc-gly)(2)(H2O)(4)]center dot 2H(2)O, in non-isothermal conditions was studied using isoconversional and ...
Trace element concentrations in wild mussels from the coastal area of the southeastern adriatic, Montenegro
(Serbian Biological Society, 2012)
The aim of the present investigation was to quantify the levels of trace elements (Zn, Cu, As, Pb, Cd and total Hg) in the Mediterranean mussel, Mytilus galloprovincialis (L.). Based on their levels, the quality of Montenegro ...
The interpretation of the intensity of components of laser scattering by interaction with matter
(The Royal Swedish Academy of Sciences, 2012)
The measurement of scattered light properties offers many optical, acoustic, dielectric, thermodynamic data about the scattering medium. Brillouin spectroscopy with various modifications and different laser types has been ...
Application of carbonized hemp fibers as a new solid-phase extraction sorbent for analysis of pesticides in water samples
(Elsevier Science Sa, Lausanne, 2012)
There is a growing interest in utilization of abundantly available materials, bio-mass or industrial byproducts, as precursors for the preparation of carbon materials. Short hemp fibers, acquired as waste from textile ...
Synthesis and characterization Pt nanocatalysts on tungsten based supports for oxygen reduction reaction
(Applied Catalysis. B: Environmental, 2012)
Platinum nanocatalysts on two tungsten based supports have been synthesized and characterized as catalysts for oxygen reduction reaction in 0.5 mol dm(-3) HClO4 solution, at 25 degrees C. Tungsten based support assigned ...
