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 ...
Size and surface effects on the MRI relaxivity of manganese ferrite nanoparticle contrast agents
(Amer Chemical Soc, Washington, 2007)
Superparamagnetic MnFe2O4 nanocrystals of different sizes were synthesized in high-boiling ether solvent and transferred into water using three different approaches. First, we applied a ligand exchange in order to form a ...
The influence of thermomechanical treatment and chemical composition on recrystallization of Al-Mg alloys
(Savez inženjera metalurgije Srbije, Beograd, 2007)
Recrystallization behaviour of AlMg3, AlMg4.5Mn and AlMg6Mn alloy plates subjected to different thermomechanical treatments (TMTs), has been studied by means of optical microscopy and hardness measurements. Applied two-stage ...
New functionalities in cellulosic fibers developed by chemical modification / Celulozna vlakna novih funkcionalnih svojstava dobijanja hemijskim modifikovanjem
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2007)
This paper gives an overview of the current state in the field of cellulosic fibers functionalization by chemical modification. Emphasis is placed on the selective (periodate and TEMPO oxidation) and non-selective (permanganate ...
Deformation behaviour of welded stainless steel: Carbon steel sandwich sheet material / Deformaciono ponašanje zavarenog spoja sendvič lima nerđajući čelik - ugljenični čelik - nerđajući čelik
(Military Technical Institute, Belgrade, 2007)
Formability of welded austenitic stainless steel (321 type) - low carbon steel (1010 type) sandwich sheet material was tested. Gas tungsten arc welding (GTAW) and shield metal arc welding (SMAW) procedures were used. After ...
The extremely high stability of carbofuran pesticide in acidic media / Ekstremno visoka stabilnost pesticida karbofurana u kiseloj sredini
(Faculty of Technology, Novi Sad, 2007)
Environment friendly iron catalysts were applied in the decomposition reactions of some toxic compounds like phenol, methomyl and corbofuran pesticide. The applied catalytic processes belong to photo-Fenton reactions. ...
Stillage as by-product of alcoholic fermentation / Džibra - sekundarni proizvod alkoholne fermentacije
(Univerzitet u Nišu - Tehnološki fakultet, Leskovac, 2007)
Processes of bioethanol production from sugars, starch or cellulose produce enormous amounts of stillage (about 20 dm3 per dm3 ethanol), as a by-product. Chemically, stillage is an aqueous solution of different products ...
Preparation of heterogeneous catalyst for biodiesel synthesis
(2007 AIChE Annual Meeting, 2007)
Certain disadvantages of conventional processes of biodiesel, e.g., fatty acid methyl esters (FAME) synthesis could be avoided by applying new technologies that are based on using heterogeneous catalyst. A new type of ...
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 ...
