Re-refining of waste mineral insulating oil by extraction with N-methyl-2-pyrrolidone
(Elsevier Science Bv, Amsterdam, 2006)
Extraction with N-methyl-2-pyrrolidone (NMP) via the three-stage mixer-settler operation was studied as possible process for re-refining of waste mineral insulating oil. The following extraction process parameters were ...
The study of coloration and antibacterial efficiency of corona activated dyed polyamide and polyester fabrics loaded with Ag nanoparticles
(Korean Fiber Soc, Seoul, 2009)
The aim of this study was to examine the influence of dyeing on antibacterial efficiency of corona activated polyamide and polyester fabrics loaded with colloidal Ag nanoparticles as well as the influence of the presence ...
Theoretical investigation of the adsorption of a binary mixture in a chromatographic column using the nonlinear frequency response technique
(Springer, New York, 2007)
The nonlinear frequency response of a chromatographic column for the adsorption of two dissolved components is analyzed using the concept of higher order frequency response functions (FRFs) which is based on the Volterra ...
Characteristics of natural isolates of lactic acid bacteria selected for construction of starter cultures for semi-hard cheese of the Trapist type
(Univerzitet u Beogradu - Fakultet veterinarske medicine, Beograd, 2001)
Starter cultures (S12, S19 and S21) for semi-hard cheese of the Trapist type were constructed by using natural isolates of lactic acid bacteria (LAB) that were mostly isolated from home-made cheese. These starter cultures ...
Synthesis and evaluation of resorcinol-based ion-exchange resins for the selective removal of cesium
(Marcel Dekker Inc, New York, 2001)
Control of the reaction conditions during the alkaline polycondensation of resorcinol with formaldehyde leads to polymeric resins with improved capacity toward caesium. The resins obtained are characterized by determining ...
Osmotic and activity coefficients of {yKCl+(1-y)MgCl2}(aq) at T=298.15 k
(Springer/Plenum Publishers, New York, 2007)
Isopiestic vapor-pressure measurements were made at the temperature 298.15 K for aqueous KCl + MgCl2 solutions using KCl(aq) as the reference standard. The measurements for these ternary solutions were made at KCl ionic ...
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 ...
Structural effects during CO adsorption on Pt-bimetallic surfaces I. The Pt(100) electrode
(Elsevier, Amsterdam, 2000)
Synchrotron surface X-ray scattering (SXS) and rotating ring disk electrode (RRDE) measurements have been performed during the coadsorption of metal adatoms and carbon monoxide on the Pt(100) surface in an electrochemical ...
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 ...
Correlation of osmotic coefficient data for ZnSO4(aq) at 25 degrees C by various thermodynamic models
(Kluwer Academic/Plenum Publ, New York, 2003)
The available literature data on the osmotic coefficient of ZnSO4(aq) at 25degreesC in the molality range from 0.1 to 4.3 mol-kg(-1) and new experimental data from 1.2 to 2.9 mol-kg(-1), at the same temperature, are ...
