Preparation and characterization of two types of covalently immobilized amyloglucosidase / Dobijanje i karakterizacija dva tipa imobilizovane amiloglukozidaze
(Serbian Chemical Soc, Belgrade, 2005)
Amyloglucosidase from A. niger was covalently immobilized onto poly(GMA-co-EGDMA) by the glutaraldehyde and periodate method. The immobilization of amyloglucosidase after periodate oxidation gave a preparate with the highest ...
Saturated-liquid heat capacity calculation of alkanes / Predskazivanje toplotnog kapaciteta zasićene tečnosti alkana
(Serbian Chemical Society, Belgrade, 2005)
An empirical model for the calculation of the heat capacity of alkanes is recommended. This model was tested and compared to known models (Luria-Benson and Růžička-Domalski) using 68 sets with 1155 literature experimental ...
Using the image analysis program for prediction of thermal stability behavior of refractory specimen
(8th International Symposium on Multifunctional and Functionally Graded Materials, FGM2004, 2005)
Most important properties which are usually measured for refractories are work temperature and thermal stability. Thermal stability of the alumina based samples was measured using a standard laboratory procedure, the water ...
Mathematical modeling and simulation of gel drying with supercritical carbon dioxide / Matematičko modelovanje i simulacija sušenja gela sa natkritičnim ugljen-dioksidom
(Serbian Chemical Society, Belgrade, 2005)
Mathematical models of alumina/silica gel supercritical drying with carbon dioxide were studied using supercritical drying experimental data. An alumina/silica gel with zinc chloride was synthesized and dried with ...
Influence of heat treatment on mechanical and sorptional properties of viscose-based nonwovens
(Niscair, 2005)
The influence of heat treatment on sorptional and mechanical properties of viscose: polypropylene (90:10) blend nonwoven fleeces has been studied. It is observed that the heat treatment improves mechanical properties ...
Aramid fiber reinforced laminar thermoplastic composite materials
(Journal of Advanced Materials, 2005)
In order to obtain a composite material with desired improved resistance to penetration of ballistic projectile, a poly(p-phenyleneterephthalamide) reinforced laminar thermoplastic composite material has been made. This ...
An investigation of influence of solvent on the degradation kinetics of carotenoids in oil extracts of Calendula officinalis / Ispitivanje uticaja ekstragensa na kinetiku razgradnje karotenoida u uljanim ekstraktima nevena
(Serbian Chemical Society, Belgrade, 2005)
The stability of carotenoids was studied in marigold oil extracts prepared with following solvents: Myritol 312®, paraffin oil, almond oil, olive oil, sunflower oil, grape seed oil, and soybean oil. The concentration of ...
Nonlinear frequency response of a chromatographic column. part I: Application to estimation of adsorption isotherms with inflection points
(Taylor & Francis Inc, Philadelphia, 2005)
A new method to determine adsorption isotherms is suggested. The method is based on analysis of the nonlinear frequency response of a chromatographic column. Due to the fact that higher order frequency response functions ...
Nanotribological properties of UHMWPE/quartz composites
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
Wear of ultra-high molecular weight polyethylene (UHMWPE) and its composites is one of the main obstacles that limit the longevity of total joint replacements. Compression molded UHMWPE/quartz composites with organosiloxane ...
Investigation on the static and fatigue failure of bi-directional composite pipes
(6th Conference of the Yugoslav Materials Research Society, YUCOMAT VI: Current Research in Advanced Materials and Processes, 2005)
The process of filament winding is particularly suited to the manufacturing of composite pipes. This paper first describes the overall process and its advantages for composite structures. Particular attention is devoted ...
