Nascut(a) in: 1950

Interese: membrane, caracterizare,transfer,modelare

Detalii:
Experienta in caracterizarea membranelor (determinarea distributiei marimii porilor cu porometrul Coulter Porometer II, permeatia de lichide, masuratori de cut-off).
Expertiza in procese de separare prin membrane (microfiltrare si ultrafiltrare).
Expertiza in modelare si simulare (optimizare neliniara, modelare fuzzy)
Cunoscator al limbajelor FORTRAN, COBOL, BASIC, MATHCAD, MATHLAB, HTML
Doctor in fizica - teza de doctorat "Influenta substantelor tensioactive asupra mediilor poroase polimerice� conducator Prof. Dr. Doc. Vasile P. Mihu. Subiectul tezei de doctorat influenta substantelor tensioactive ionice si neionice asupra prepararii si separarii prin membrane. Membranele preparate au fost caracterizate prin SEM, masuratori de distributia marimii porilor, si permeabilitatea fluidelor s-au utilizat la separarea solvitilor mic moleculari prin ultrafiltrarea coloidala

Details:
Experience in membrane characterization (pore size measurements by wet-dry porometry Coulter Porometer II, fluid permeability, cut-off measurements at the Research Center for Macromolecular Materials and Membranes).
Experience in membrane separation processes (microfiltration and ultrafiltration).
Experience in computer modeling and simulation (non-linear fitting, fuzzy modeling)

The Ph.D. dissertation has the title �Influence of surfactants upon polymer porous media� and was supervised by Prof. Dr. Doc. Vasile P. Mihu. The main topic of the thesis includes the influence of ionic and non-ionic surfactants on membrane preparation and separation. The prepared membranes, characterized by scanning electron microscopy, pore size measurements and fluid permeability were used at the separation of small size solutes by means of colloid enhanced ultrafiltration.
