Preparation of heterogeneous catalyst for biodlesel synthesis
(2007 AIChE Annual Meeting, 2007)
Certain disadvantages of conventional processes of biodiesel, i.e. fatty acid methyl esters (FAME) synthesis could be avoided by applying new technologies which are based on using heterogeneous catalyst. In this study a ...
Oxygen transport in tissue engineering systems: Cartilage and myocardium
(Fluid Dynamics and Materials Processing, 2007)
Efficient transport of oxygen is one of the main requirements in tissue engineering systems in order to avoid cell death in the inner tissue regions and support uniform tissue regeneration. In this paper, we review approaches ...
Characterization of wastewater streams from Bor site
(Savez inženjera metalurgije Srbije, Beograd, 2007)
This paper presents full characterization of wastewater streams within Bor copper mine. Seven different wastewater streams were identified and fully characterized (origin, flow rate, chemical and physical properties) on ...
Synthesis and characterization of biodegradable aliphatic copolyesters with poly(tetramethylene oxide) soft segments
(Wiley, Hoboken, 2007)
A series of aliphatic poly(ether-ester)s based on flexible poly(tetramethylene oxide) (PTMO) and hard poly (butylene succinate) (PBS) segments were synthesized by the catalyzed two-step transesterification reaction of ...
Approximation of material behaviour of PLLA polymer in HAp/PLLA biocomposite material using nanoindentation and finite element method
(Savez inženjera metalurgije Srbije, Beograd, 2007)
In this work, a combination of nanoindentation experiment and finite element modeling is proposed in order to obtain approximate material behavior of PLLA polymer in hydroxyapatite (HAp)/poly-L-lactide (PLLA) composite. ...
Thermal, oxidative and radiation stability of polyimides. Part IV: Polyimides based on N-[4-benzoyl-2-(2,5-dioxo-2,5-dihydro-pyrrol-1-yl)-phenyl]-acetamide and different diamines
(Elsevier Sci Ltd, Oxford, 2007)
Polyimide resins were obtained from the reaction between N-[4-benzoyl-2-(2,5-dioxo-2,5-dihydro-pyrrol-1-yl)-phenyl]-acetamide and the following compounds with terminal amino groups: urea, 4-[(4-aminophenyl)sulfonyl] aniline, ...
Volumetric properties of the binary methanol plus chloroform and ternary methanol plus chloroform plus benzene mixtures at (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K
(Amer Chemical Soc, Washington, 2007)
Densities rho of the ternary system of methanol + chloroform + benzene and binary mixture of methanol + chloroform have been measured at six temperatures (288.15, 293.15, 298.15, 303.15, 308.15, and 313.15) K and atmospheric ...
Direct hemp cellulose dissolution in N-Methylmorpoline-N-Oxide
(Taylor & Francis Inc, Philadelphia, 2007)
The increased production of bast fibres (especially hemp fibres) brought about an increase in the amount of waste, namely shive (hemp stalks) and short fibres. This waste presents a potential significant source of high ...
The effect of fermentation medium composition on lipase production by yeast Candida utilis / Uticaj sastava fermentacione podloge na prinos produkovanih lipaza pomoću kvasca Candida utilis
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2007)
In this work lipolytic activity of various microorganisms isolated from spoiled soybean oil was studied. Wild yeast strain identified as Candida utilis was chosen for the producing microorganism based on the activity shown ...
Photocatalytic degradation of textile dye CI Basic Yellow 28 in water by UV-A/TiO2
(Association of the Chemical Engineers of Serbia, 2007)
CI Basic Yellow 28 (BY28), commonly used as a textile dye, could be photocatalytically degraded using TiO2 as catalyst and irradiated by UV-A lamp (300 W). However, UV and TiO2 showed no effect on the photodegradation when ...
