A novel bioreactor with mechanical stimulation for skeletal tissue engineering
(Association of the Chemical Engineers of Serbia, 2009)
The provision of mechanical stimulation is believed to be necessary for the functional assembly of skeletal tissues, which are normally exposed to a variety of biomechanical signals in vivo. In this paper, we present a ...
Diffusion of lidocaine hydrochloride from lipid microparticles
(Association of the Chemical Engineers of Serbia, 2009)
Lipid particles, as drug carriers, are of increasing research interest, because a sustained drug release and avoidance of side effects could be achieved by using them. Lidocaine hydrochloride is a very efficient local ...
Viscosity of binary non-electrolyte liquid mixtures: Prediction and correlation
(Association of the Chemical Engineers of Serbia, 2008)
The viscosity of 31 binary liquid mixtures containing diverse groups of organic compounds, determined at atmospheric pressure: alcohols, alkanes (cyclo and aliphatic), esters, aromatics, ketones etc., were calculated using ...
A mass transfer heterogeneous in systems by the adsorption method
(Association of the Chemical Engineers of Serbia, 2009)
A mass transfer coefficient between: A liquid and single sphere and a liquid And a column wall in packed and fluidized beds of a spherical inert Particle have been studied experimentally using the adsorption method. The ...
Concentrations of Cu, Zn, Cd and Pb in urban soils in parks and green areas of Belgrade / Zagađenje metalima urbanog zemljišta u parkovima i zelenim površinama u Beogradu
(Association of the Chemical Engineers of Serbia, 2006)
Several metals in urban soils of Belgrade were extracted by two methods which respectively give estimates of the available and "quasi total" contents. Soil samples were collected from six parks and three green areas within ...
In vitro evaluation of the controlled release of antibiotics from liposomes / In vitro ispitivanje kontrolisanog otpuštanja antibiotika iz liposoma
(Association of the Chemical Engineers of Serbia, 2003)
Results of this study have shown significantly prolonged release of selected antibiotic from liposome dispersion as compared to free antibiotic solution of the same initial concentration. Two models of non-steady one-dimensional ...
Preparation and characterization of penicillin acylase immobilized on sepabeads EC-EP carrier
(Association of the Chemical Engineers of Serbia, 2007)
This paper reports the covalent immobilization of penicillin G acylase from E. coli on Sepabeads EC-EP, an epoxy-activated polymethacrylic carrier, and describes the properties of the immobilized enzyme. Due to its versatility ...
Kovats retention index-boiling point relationship of 2-phenyl-2-alkyl-acetonitriles on stationary phases of different polarity / Zavisnost kovačevog retencionog indeksa od temperature ključanja 2-fenil-2-alkilacetonitrila na stacionarnim fazama različite polarnosti
(Association of the Chemical Engineers of Serbia, 2005)
Linear and reciprocial Kovats retention index-boiling point relationships known from the literature were used to study the Kovats retention index-boiling point dependence of 2-phenyl-2-alkylacetonitriles on stationary ...
The optimization of zinc dialkyldithiocarbamates synthesis and determination of their antioxidant activity
(Association of the Chemical Engineers of Serbia, 2008)
A two-step optimized laboratory synthetic method of zinc dialkyldithiocarbamates is presented. In the course of the first phase, a sodium salt of dialkyldithiocarbamic acid has been synthesized from the dialkylamines, ...
Nanocomposite powders for new contact materials based on copper and alumina
(Association of the Chemical Engineers of Serbia, 2008)
This paper is a contribution to characterization of Cu-Al2O3 powders with nanostructure designed for the production of dispersion strengthened contact materials. New materials with predetermined properties can be successfully ...
