Benzylation of N-phenyl-2-phenylacetamide under microwave irradiation / Benzilovanje N-fenil-2-fenilacetamida pomoću mikrotalasnog zračenja
(Serbian Chemical Society, Belgrade, 2008)
N-Phenyl-2-phenylacetamide was alkylated with benzyl chloride in the presence of powdered potassium hydroxide under microwave irradiation in a solvent-free system. The reactions were also performed in the presence of ...
Prediction of service life of cordierite-mullite refractory materials by non-destructive methods
(9th International Conference on Multiscale and Functionally Graded Materials, FGM IX, 2008)
Ultrasonic pulse velocity testing was used to perform non-destructive quality control of refractory plates used as substrates in fast firing of porcelain whitewares. The measurement of the ultrasonic velocity was used to ...
Antimicrobial activity of celery fruit isolates and SFE process modeling
(Elsevier, Amsterdam, 2008)
Method for determining refractory specimen heat resistance
(Springer, New York, 2008)
The most important properties governing the operation of refractories are refractoriness, service temperature and heat resistance. The heat resistance of specimens based on Al2O3 is determined by a standard laboratory ...
Surface characteristics and antibacterial activity of a silver-doped carbon monolith
(Natl Inst Materials Science, Ibaraki, 2008)
A carbon monolith with a silver coating was prepared and its antimicrobial behaviour in a flow system was examined. The functional groups on the surface of the carbon monolith were determined by temperature-programmed ...
Reciklovanje poliolefinskog otpada do energenta / Polyolephine waste recycling as source of power energy
(Association of Chemical Engineers of Serbia, 2008)
Poliolefinski otpad (polietilen, polipropilen) izvor je zagađivanja okoline. Razvijen je
veliki broj postupaka za reciklovanje poliolefinskog otpada. U ovome radu je prikazan
tehnološki postupak pod oznakom T-tehnologija® ...
Refining of corrosive insulating oils by selective liquid-liquid extraction process
(42nd International Conference on Large High Voltage Electric Systems 2008, CIGRE 2008, 2008)
In recent years copper sulphide formation in transformer windings has been recognized as one significant risk factor for operation of power transformers, due to number of failures which have occurred as a consequence of ...
Service life prediction for refractory materials
(Springer, New York, 2008)
Ultrasonic pulse velocity testing and image analysis were used to predict the thermal stability of cordierite-mullite refractories. Two compositions used as substrates in fast firing of porcelain whiteware, characterized ...
Estimation of single solute adsorption isotherms applying the nonlinear frequency response method using non-optimal frequencies
(Elsevier, Amsterdam, 2008)
In order to estimate single solute adsorption isotherms, the nonlinear frequency response (FR) of a chromatographic column is analyzed experimentally and evaluated using the concept of higher order frequency response ...
Heat transfer coefficient and pressure drop during refrigerant R-134a condensation in a plate heat exchanger
(Versita, Warsaw, 2008)
The condensation heat transfer coefficient and the two-phase pressure drop of refrigerant R-134a in a vertical plate heat exchanger were investigated experimentally. The area of the plate was divided into several segments ...
