A novel method for production of PVA-based microfibers by freezing/thawing cycles in hydrophilic settings
(Wiley-Blackwell, Hoboken, 2014)
The effect of different extractants on lead desorption from a natural mineral
(Elsevier, Amsterdam, 2015)
Natural minerals, such as quartz, clinoptilolite and calcite, are useful as sorbents for various applications, but their content of heavy metals ions is the most problematic obstacle to their application. Before their ...
Trace analysis of selected hormones and sterols in river sediments by liquid chromatography-atmospheric pressure chemical ionization-tandem mass spectrometry
(Elsevier, Amsterdam, 2014)
In this paper, development and optimization of new LC-MS method for determination of twenty selected hormones, human/animal and plant sterols in river sediments were described. Sediment samples were prepared using ultrasonic ...
Cavitation resistance of refractory concrete: Influence of sintering temperature
(Elsevier Sci Ltd, Oxford, 2013)
The purpose of this study was to investigate possible application of refractory concrete in conditions of cavitation effect where the metal materials are usually applied. Also, influence of different sintering temperatures ...
Heat transfer between a packed bed and a larger immersed spherical particle
(Pergamon-Elsevier Science Ltd, Oxford, 2014)
In this paper, heat transfer coefficients between the hot packed beds of particles and the larger cold immersed sphere were experimentally determined. The packed beds consisted of mono-sized spherical glass particles of ...
Poly(methacrylic acid) based hydrogels as sorbents for removal of cationic dye basic yellow 28: Kinetics, equilibrium study and image analysis
(Elsevier Science Sa, Lausanne, 2013)
Poly(methacrylic acid) based hydrogels with neutralization degree of monomer of 0% (PMAA/0) and 80% (PMAA/80) were synthesized and their sorption potentials toward model cationic dye, basic yellow 28 (BY28), from aqueous ...
Preparation, characterization and mechanical properties of Bi12SiO20-PMMA composite films
(Elsevier Science Sa, Lausanne, 2014)
This paper investigates processing and characterization of polymer composite material PMMA-Bi12SiO20 (BSO). Thin films of pure PMMA and composites with 0.5 and 1.0 wt% of Bi12SiO20 powder were made using solution casting ...
Transient thermal response of textile fabrics made of natural and regenerated cellulose fibers
(Elsevier Sci Ltd, Oxford, 2014)
The thermal parameters that describe the transient response of cellulose textile fabrics due to the changes in physiological and environmental conditions were analyzed. Starting from the specific heat of the knitted fabrics ...
Cobalt-Releasing 1393 Bioactive Glass-Derived Scaffolds for Bone Tissue Engineering Applications
(Amer Chemical Soc, Washington, 2014)
Loading biomaterials with angiogenic therapeutics has emerged as a promising approach for developing superior biomaterials for engineering bone constructs. In this context, cobalt-releasing materials are of interest as Co ...
Lactic acid production on liquid distillery stillage by Lactobacillus rhamnosus immobilized onto zeolite
(Elsevier Sci Ltd, Oxford, 2013)
In this study, lactic acid and biomass production on liquid distillery stillage from bioethanol production with Lactobacillus rhamnosus ATCC 7469 was studied. The cells were immobilized onto zeolite, a microporous ...
