Polyamidoamine as a clay modifier and curing agent in preparation of epoxy nanocomposites
(Elsevier Science Sa, Lausanne, 2019)
In the present study the commercial multifunctional fatty acid polyamidoamine (PAA) was for the first time simultaneously applied as a curing agent and clay modifier for epoxy/clay nanocomposites (NC) based on diglycidyl ...
Synthesis and thermal properties of arylazo pyridone dyes
(Elsevier Sci Ltd, Oxford, 2019)
Thermal degradation properties of 5-(4-substitutedphenylazo)-3-amido-6-hydroxy-4-methy1-2-pyridones and 5-(4-substitutedphenylazo)-3-cyano-6-hydroxy-4-methy1-2-pyridones dyes, differing in electron withdrawing and electron ...
Achieving high antimicrobial activity: Composite alginate hydrogel beads releasing activated charcoal with an immobilized active agent
(Elsevier Sci Ltd, Oxford, 2018)
New composites based on Ca-alginate hydrogels were produced that release activated charcoal (AC) particles with adsorbed povidone iodine (PVP-I) as a model antimicrobial substance in a physiological-like environment. ...
Structural Elucidation of Enzymatically Synthesized Galacto-oligosaccharides Using Ion-Mobility Spectrometry Tandem Mass Spectrometry
(Amer Chemical Soc, Washington, 2016)
Galacto-oligosaccharides (GOS) represent a diverse group of well-characterized prebiotic ingredients derived from lactose in a reaction catalyzed with beta-galactosidases. Enzymatic transgalactosylation results in a mixture ...
