Phase transformation in cordierite gel synthesized by non-hydrolytic sol-gel route
(Elsevier Sci Ltd, Oxford, 2007)
Cordierite gel was synthesized by non-hydrolytic sol-gel route, starting from aluminum chloride, TEOS and magnesium chloride dissolved in absolute ethanol. Crystallization of p.-cordierite from gel at temperatures between ...
Plasma-induced Decolorization of Indigo-dyed Denim Fabrics Related to Mechanical Properties and Fiber Surface Morphology
(Sage Publications Ltd, London, 2009)
The aim of this study was to investigate how morphology of fibers is affected by plasma during the process of decolorization by a low-pressure RF plasma (gas, treatment time, and power were varied) and atmospheric pressure ...
Static holdup in Gas - Flowing solids - Fixed bed contactors
(Elsevier Science Bv, Amsterdam, 2009)
Static holdup was investigated experimentally and theoretically in gas - flowing solids - fixed bed bench-scale contactors. Diverse packing elements were used: Raschig rings, ceramic beads, crushed stone and glass beads. ...
Study on the formation of an amoxicillin adduct with methanol using electrospray ion trap tandem mass spectrometry
(Wiley, Hoboken, 2008)
The possibility of using the protonated methanol-adduct of antimicrobial amoxicillin for its identification and quantification at residue levels has been investigated, since it is impossible to completely suppress the ...
Poly(acrylamide-co-itaconic acid) and semi-IPNS with poly(ethylene glycol): Preparation and characterization
(Wiley-VCH Verlag Gmbh, Weinheim, 2004)
A pH-responsive poly(acrylamide-co-itaconic acid) (PAAm/IA) hydrogel and semi-interpenetrating networks (semi-IPNs) with 5, 10 and 15 wt.-% of poly(ethylene glycol) (PAAm/IA/PEG), were synthesized. Their swelling behavior ...
Thermal Properties of PMMA/TiO2 Nanocomposites Prepared by In-Situ Bulk Polymerization
(Wiley-Blackwell, Malden, 2009)
The surface of anatase TiO2 nanoparticles, obtained by the controlled hydrolysis of titanium tetrachloride, was modified by 6-palmitate ascorbic acid. The surface modified TiO2 nanoparticles were dispersed in methyl ...
Influence of cubic alpha-Fe2O3 particles on the thermal stability of poly(methyl methacrylate) synthesized by in situ bulk polymerization
(Elsevier Sci Ltd, Oxford, 2009)
Poly(methyl methacrylate)/alpha-Fe2O3 Composites were prepared by in situ bulk radical polymerization of methyl methacrylate in the presence of the cubic alpha-Fe2O3 particles using 2,2'-azobisisobutyronitrile as initiator. ...
Characterization and quantitative analysis of surfactants in textile wastewater by liquid chromatography/quadrupole-time-of-flight mass spectrometry
(Wiley, Hoboken, 2008)
A method based on the application of ultra-performance liquid chromatography (UPLC) coupled to hybrid quadrupole-time-of-flight mass spectrometry (QqTOF-MS) with an electrospray (ESI) interface has been developed for the ...
Solids flow pattern in gas-flowing solids-fixed bed contactors. Part I Experimental
(Pergamon-Elsevier Science Ltd, Oxford, 2009)
An experimental investigation of the solids flow pattern in gas-flowing solids-fixed bed contactors is presented. The apparatus and procedures for determining the dynamic and static solids holdups, solids residence time ...
Photoreactive hyperbranched urethane acrylates modified with a branched saturated fatty acid
(Elsevier, Amsterdam, 2006)
Urethane acrylate resins based on partially modified aliphatic hyperbranched polyesters (HBP) were synthesized. HBP of the second and the third pseudo-generation were synthesized from 2,2-bis(hydroxymethyl)propionic acid ...
