Volumetric properties of the ternary system ethanol plus 2-butanone plus benzene by the van der Waals and Twa-Coon-Bluck-Tilton mixing rules: experimental data, correlation and prediction
(Elsevier, Amsterdam, 2004)
Densities of the ternary system ethanol + 2-butanone + benzene and its binaries ethanol + 2-butanone, ethanol + benzene and 2-butanone + benzene were measured at T = 298.15 K and atmospheric pressure. From these densities ...
Oxygen reduction reaction on Pt(111): effects of bromide
(Elsevier Science Sa, Lausanne, 1999)
Using the rotating ring-disk technique (RRDE) the oxygen reduction reaction (orr) was studied on the Pt(111) surface in the presence of Br- anions. We found that the orr at the Pt(111) \ Br-ad interface is always accompanied ...
The kinetics of the thermal degradation of isomeric dipropyl and dibutyl esters of poly(itaconic acid)
(Pergamon-Elsevier Science Ltd, Oxford, 2000)
Non-oxidative and oxidative thermogravimetry was performed on poly(di-n-propyl-) (PDnPI), poly(di-iso-propyl-) (PDiPI), poly(di-n-butyl-) (PDnBI), poly(di-iso-butyl-) (PDiBI) and poly(di-sec-butyl itaconate) (PDsBI). The ...
Recycled-wool-based nonwoven material as a sorbent for lead cations
(Wiley, Hoboken, 2003)
The aim of this study was to investigate the sorption properties of a recycled-wool-based nonwoven material for lead cations. To improve sorption properties, the material was treated with low-temperature air plasma and/or ...
Investigation of Ca-alginate hydrogel rheological behaviour in conjunction with immobilized yeast cell growth dynamics
(Taylor & Francis Ltd, Abingdon, 2007)
The rheological model is developed to elucidate the mechanism of Ca-alginate microbead deformation in the course of cell growth within. It is a complex process influenced by relaxation of the expanded polymer network inside ...
Multiphysics modeling of electric-swing adsorption system with in-vessel condensation
(Springer, Dordrecht, 2007)
Mathematical modeling of an Electric-Swing Adsorption (ESA) system (adsorption cycle with electrothermal desorption step, performed by direct heating of the adsorbent particles by passing electric current through them), ...
Shrinkage properties of wool treated with low temperature plasma and chitosan biopolymer
(Textile Research Inst, Princeton, 1999)
Low temperature plasma treatments of wool modify only the cuticle surface of the fibers, improving their surface wettability, dyeability, fiber cohesion, and shrink resistance. The shrink-resist properties obtained with ...
The thermal degradation of some isomers of poly(di-butyl itaconates)
(Elsevier, Amsterdam, 1999)
The non-oxidative and oxidative thermal degradation of poly(di-iso-butyl itaconate) (PDiBI), poly(di-n-butyl itaconate) (PDnBI), and poly(di-sec-butyl itaconate) (PDsBI) were studied by following changes in the polymer ...
Synthesis, structure, and solvatochromic properties of pharmacologically active 5-substituted 5-phenylhydantoins
(Springer Wien, Wien, 2011)
A series of 5-substituted 5-phenylhydantoins was synthesized and their UV absorption spectra were recorded in the region 200-400 nm in selected solvents of different polarity. The effects of solvent dipolarity/polarizability ...
Characterization of autochthonous Lactobacillus paracasei strains on potential probiotic ability
(Croatian Dairy Union, 2010)
Lactic acid bacteria strains isolated from traditional made cheeses constitute a reservoir of unexplored potential in biotechnology. In this study four autochthonous lactobacilli strains, isolated from traditional white ...
