Viscosity of the binary systems 2-methyl-2-propanol with n-alkanes at T=(303.15, 308.15, 313.15, 318.15 and 323.15)K: Prediction and correlation - New UNIFAC-VISCO interaction parameters
(Elsevier Science Bv, Amsterdam, 2010)
Viscosities for the binary mixtures 2-methyl-2-propanol + n-heptane, +n-octane, +n-nonane and +n-decane have been measured at 303.15, 308.15, 313.15, 318.15 and 323.15 K and atmospheric pressure. Viscosity deviations for ...
Short-circuit oxygen diffusion in thermally grown silica layer
(World Scientific Publ Co Pte Ltd, Singapore, 2010)
Amorphous polymer-derived Si-C-N ceramics can be doped with different elements (Al, B etc.) through various pre-ceramic polymer routes. Thus, controlling of the high temperature oxidation resistance can be achieved on an ...
Isopiestic determination of the osmotic and activity coefficients of the {yKCl + (1-y)K2HPO4}(aq) system at T=298.15 K
(Academic Press Ltd- Elsevier Science Ltd, London, 2011)
The osmotic coefficients of aqueous mixtures of KCl and K2HPO4 have been measured at T = (298.15 +/- 0.01) K by the isopiestic vapor pressure method over the range of ionic strengths from (2.3700 to 11.250) mol . kg(-1) ...
Complexation of amidated pectin with poly(itaconic acid) as a polycarboxylic polymer model compound
(Elsevier Sci Ltd, Oxford, 2011)
Complexes based on amidated pectin (AP) and poly(itaconic acid) (PIA) were prepared by casting films from solutions of AP and PIA in different ratios with the pectin amount ranging from 10% to 90% by mass. The complexes ...
The phase equilibrium of triglycerides and ethanol at high pressure and temperature: The influence on kinetics of ethanolysis
(Elsevier Science Bv, Amsterdam, 2012)
Biodiesel synthesis by ethanolysis of triglycerides conducted under high pressure and at elevated temperature can lead to high levels of conversion and biodiesel yield over short reaction time. The vapour-liquid or ...
Oxidation of carbon monoxide and formic acid on bulk and nanosized Pt-Co alloys
(Springer, New York, 2012)
Bulk Pt3Co and nanosized Pt3Co and PtCo alloys supported on high area carbon were investigated as the electrocatalysts for the COads and HCOOH oxidation. Pt3Co alloy with Co electrochemically leached from the surface (Pt ...
Optimization of Active Carbonaceous Material Obtained by Low Hydrothermal Carbonization of Plane Tree Seed with H3PO4
(Trans Tech Publications Ltd, Durnten-Zurich, 2017)
Activated carbons (ACs) were successfully prepared using plane tree seed (PTS) as a cheap and renewable raw material. The plane tree seeds were firstly treated combining magnetic (MM) and ultrasonic mixing (USM) during ...
Fabrication and characterization of HA-ZrO2-MWCNT ceramic composites
(Sage Publications Ltd, London, 2010)
In this article, a new kind of hydroxyapatite-zirconia-carbon nanotube (HA-ZrO2-MWCNT) ceramic composites was fabricated to enhance the mechanical properties of a hydroxyapatite (HA) ceramic for satisfying various requirements ...
Comparative analysis of fecal DNA extraction methods with phylogenetic microarray: Effective recovery of bacterial and archaeal DNA using mechanical cell lysis
(Elsevier Science Bv, Amsterdam, 2010)
Several different protocols are used for fecal DNA extraction, which is an integral step in all phylogenetic and metagenomic approaches to characterize the highly diverse intestinal ecosystem. We compared four widely used ...
Rearrangement of erythrocyte band 3 molecules and reversible formation of osmotic holes under hypotonic conditions
(Springer, New York, 2010)
The complex phenomenon of rearrangement of band 3 molecules after erythrocyte swelling under hypotonic condition is considered. The rearrangement includes the increase of the mobile fraction and clustering of band 3. The ...
