Encapsulation of thyme (Thymus serpyllum L.) aqueous extract in calcium alginate beads
(Wiley, Hoboken, 2012)
BACKGROUND: Encapsulation of Thymus serpyllum L. aqueous extract within calcium alginate beads was studied in order to produce dosage formulations containing polyphenolic compounds. Electrostatic extrusion was applied for ...
Sol-gel technology for functional finishing of PES fabric by stimuli-responsive microgel
(Springer, New York, 2012)
The possibility of incorporating a stimuli-responsive microgel into a silica matrix by the sol-gel method was studied. This method allows the preparation of a novel class of functional finishes for textile material ...
Crystallization behavior and sintering of cordierite synthesized by an aqueous sol-gel route
(Elsevier Sci Ltd, Oxford, 2012)
The purpose of the research was to investigate crystallization behavior and sintering of cordierite synthesized by a low-price aqueous sol gel route starting from silicic acid and magnesium and aluminum salts. Viscous ...
Liquid-liquid and solid-liquid equilibria in the solutions of poly(ethylene glycol) with several organic solvents
(Elsevier, Amsterdam, 2012)
In this work, liquid-liquid and solid-liquid equilibria (LLE and SLE, respectively), at atmospheric pressure, of the solutions of poly(ethylene glycol) (PEG) with several organic solvents were studied. The studied solvents ...
Catalysis of oxygen reduction on Au modified by Pd nanoislands in perchloric acid solution
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
Oxygen reduction reaction (ORR) was studied on polycrystalline gold, Au(poly), modified by nanosized palladium islands in 0.1 M HClO4 solution using rotating disc electrode technique. Paladium was spontaneously deposited ...
Influence of the gelation and calcination temperatures on physical parameters and photocatalytic activity of mesoporous titania powders synthesized by the nonhydrolytic sol-gel process
(Elsevier, Amsterdam, 2012)
Titania powders were synthesized by nonhydrolitic sol-gel process starting from titanium(IV)-chloride, titanium(IV)-isopropoxide and carbon-tetrachloride. Gelation was performed in solvothermal conditions, at 140 degrees ...
Multivariate evaluation of the correlation between retention data and molecular descriptors of antiepileptic hydantoin analogs
(Wiley-Blackwell, Malden, 2012)
Molecular properties relevant to pharmacokinetics of two sets of newly synthesized hydantoin derivatives based on two well-known drugs (Nirvanol and Phenytoin) were studied. Properties under consideration were either ...
Kinetics measurements and in situ Raman spectroscopy of formation of hydrogen-tetrabutylammonium bromide semi-hydrates
(Pergamon-Elsevier Science Ltd, Oxford, 2012)
The kinetics of formation of H-2-TBAB semi-clathrate hydrates was studied in this work in order to elucidate their potential for H-2 storage. The influence of pressure (5-16 MPa), TBAB concentration (2.6 mol% and 3.7 mol%) ...
Liquid velocity in a high-solids-loading three-phase external-loop airlift reactor
(Wiley-Blackwell, Hoboken, 2012)
BACKGROUND: Airlift reactors are of interest for many different processes, especially for three-phase systems. In this study the behavior of a high-loading three-phase external-loop airlift reactor was examined. In particular, ...
The inhibitory effect of oregano extract on the growth of Aspergillus spp. and on sterigmatocystin biosynthesis
(Elsevier, Amsterdam, 2012)
The aim of this study was to investigate the effect of oregano extract on the growth of Aspergillus species (Aspergillus niger, Aspergillus carbonarius, and Aspergillus wentii) isolated from food and biosynthesis of ...
