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 ...
Copolymer hydrogels based on N-isopropylacrylamide and itaconic acid
(Elsevier Sci Ltd, Oxford, 2006)
In this study, the swelling behaviour of copolymer hydrogels of N-isopropylacrylamide (NIPAM) and itaconic acid (IA) in response to temperature and pH value of the external media was studied. The equilibrium degree of ...
Chitosan/acid dye interactions in wool dyeing system
(Elsevier Sci Ltd, Oxford, 2005)
This study assesses the interactions that could occur during dyeing of the chitosan treated wool fibres on basis of the spectrophotometric study, by measuring the absorbance values of the solutions containing dye and ...
Design of ion-exchange resins selective of caesium. Synergistic effect of macrocycle in phenolic resins
(Marcel Dekker Inc, New York, 2001)
The extraction of caesium by resorcinol based resins was investigated. At high hydroxide concentration ([OH-] = 0.15 M), the alkali-metal cations' sorption selectivity (determined in competitive extraction system) for ...
Improvement to the Flynn-Wall method of determining apparent activation energies of the thermal degradation of polymers
(Amer Chemical Soc, Washington, 2003)
An improvement to the Flynn-Wall method of determining apparent activation energies of the thermal degradation of polymers is presented. The method involves the deconvolution of differential thermogravimetric (TG) curves ...

(Elsevier Ltd, 2019)
Various organizations have endeavored to develop assessment methods for the identification and management of weaknesses in hospital disaster preparedness. Although the largest number of patients receive their regular care ...
Synthesis and characterization of Pt nanocatalyst on Ru0.7Ti0.3O2 support as a cathode for fuel cells application
(Elsevier Science Sa, Lausanne, 2015)
Ruthenium oxide/titanium oxide, with a Ru:Ti atomic ratio of 7:3 was synthesized by modified sol-gel procedure and used as a support for platinum nanocatalyst for oxygen reduction reaction. The synthesized materials were ...
Upregulation of Heme Oxygenase-1 in Response to Wild Thyme Treatment Protects against Hypertension and Oxidative Stress
(Hindawi Ltd, London, 2016)
High blood pressure is the most powerful contributor to the cardiovascular morbidity and mortality, and inverse correlation between consumption of polyphenol-rich foods or beverages and incidence of cardiovascular diseases ...
Structural changes in the fabrication and ageing of PA66 textured yarn
(Wiley-VCH Verlag Gmbh, Weinheim, 2005)
The characterization of textured yarn is of great significance for both producers and final users. The influence of the texturing parameters (draw ratio and heater temperature) on the characteristics of the textured polyamide ...
Oxygen reduction reaction on Pt and Pt-bimetallic electrodes covered by CO - Mechanism of the air bleed effect with reformate
(Electrochemical Soc Inc, Pennington, 2005)
The oxygen reduction reaction (ORR) has been studied on CO-covered Pt(111), Pt(110), Pt-poly, Pt-Ru, Pt3Sn(111), and Pt3Sn( 110) electrodes in 0.5 M H2SO4 solution at temperatures varying between 298 and 333 K using the ...
