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 ...
Synthesis, solvent interactions and computational study of monocarbohydrazones
(Springer International Publishing Ag, Cham, 2020)
Carbohydrazones are compounds that are increasingly studied due to their wide potential biological activity. Monocarbohydrazones (mCHs), as one of the carbohydrazone derivatives, so far have been poorly investigated. For ...
Electrochemical decolorization of CI Acid Orange 3 in the presence of sodium chloride at iridium oxide electrode
(Springer International Publishing Ag, Cham, 2017)
The electrocatalytic degradation of C.I. Acid Orange 3 from simulated wastewater by indirect electrochemical oxidation using an IrOx electrode was investigated. The effects of different operating parameters on the rate of ...
Prediction of excess molar volumes of binary mixtures of organic compounds from refractive indices
(Versita, Warsaw, 2008)
The excess molar volumes of 51 binary mixtures containing diverse groups of organic compounds: alcohols (methanol, ethanol, propan-1-ol, butan-1-ol, pentan-1-ol, hexan-1-ol, and heptan-1-ol), (cyclo-) alkanes (hexane, ...
Immobilization of modified penicillin G acylase on Sepabeads carriers
(Versita, Warsaw, 2009)
An approach to stable covalent immobilization of chemically modified penicillin G acylase from Escherichia coli on Sepabeads(R) carriers with high retention of hydrolytic activity and thermal stability is presented. The ...
Lipase immobilization in a hollow fibre membrane reactor: Kinetics characterization and application for palm oil hydrolysis
(Versita, Warsaw, 2004)
Feasibility of lipase immobilization in a hydrophilic hollow fibre membrane reactor for oil hydrolysis has been demonstrated. A simple immobilization technique was applied resulting in about 155 mg m(-2) of immobilized ...
