Volumetric and Viscometric Behavior of Binary Systems 2-Butanol + PEG 200, + PEG 400, + Tetraethylene Glycol Dimethyl Ether, and plus N-Methyl-2-pyrrolidone
(Amer Chemical Soc, Washington, 2013)
Experimental data on densities, viscosities, and refractive indices of binary mixtures with 2-butanol and polyethylene glycols of different molecular weights, tetraethylene glycol dimethyl ether, or N-methyl-2-pyrrolidone, ...
Galacto-oligosaccharide synthesis using chemically modified beta-galactosidase from Aspergillus oryzae immobilised onto macroporous amino resin
(Elsevier Sci Ltd, Oxford, 2016)
The goal of this study was to establish an efficient immobilisation protocol for beta-galactosidase from Aspergillus oryzae onto the polystyrenic macroporous resin Purolite (R) A-109 for better utilisation of its ...
Kinetics, mechanism, and DFT calculations of thermal degradation of a Zn(II) complex with N-benzyloxycarbonylglycinato ligands
(Springer Wien, Wien, 2012)
A Zn(II) complex with N-benzyloxycarbonylglycinato ligands was studied by non-isothermal methods, in particular Kissinger-Akahira-Sunose's method, and further analysis of these results was performed by Vyazovkin's algorithm ...
Characterization of the Ag43Cu37Zn20 alloy surface after potentiostatic polarization using LDI-TOF mass spectrometry
(Walter de Gruyter Gmbh, 2017)
This work is the first to demonstrate the possibilities of direct analysis of the corrosion film formed on Ag43Cu37Zn20 alloy using laser desorption/ionization (LDI) on a commercial matrix-assisted LDI time of flight mass ...
Comparative analysis of process parameters of talc mechanical activation in centrifugal and attrition mill
(Oficyna Wydawnicza Politechniki Wroclawskiej, Wroclaw, 2014)
The efficiency of talc mechanical activation by means of two different mechano-activators centrifugal and attrition mill is investigated in this study and the comparative analysis of the characteristics of obtained talc ...
Aroma formation by immobilized yeast cells in fermentation processes
(Wiley, Hoboken, 2015)
Immobilized cell technology has shown a significant promotional effect on the fermentation of alcoholic beverages such as beer, wine and cider. However, genetic, morphological and physiological alterations occurring in ...
Mathematical modeling of cross-linking monomer elution from resin-based dental composites
(Wiley-Blackwell, Hoboken, 2013)
Elution of potentially toxic substances, including monomers, from resin-based dental composites may affect the biocompatibility of these materials in clinical conditions. In addition to the amounts of eluted monomers, ...
Synthesis and Characterization of Novel Urethane-Siloxane Copolymers with a High Content of PCL-PDMS-PCL Segments
(Wiley-Blackwell, Malden, 2011)
Novel polyurethane copolymers derived from 4,4'-methylenediphenyl diisocyanate (MDI), 1,4-butanediol (BD) and alpha, omega-dihydroxy-[poly(caprolactone)-poly (dimethylsiloxane)-poly(caprolactone)] (a, x-dihydroxy( ...
Preparation and characterization of pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid
(Wiley-Blackwell, Hoboken, 2011)
Novel pH-sensitive hydrogels based on chitosan, itaconic acid and methacrylic acid were prepared in two steps. Chitosan was first ionically crosslinked with itaconic acid, after which a free radical polymerization and ...
