Abstract Casein as the major protein of milk is a promising source for biopolymer fibers. Current casein-based fibers are fabricated by dissolving caseins in alkaline media and wet spinning coagulation bath containing harsh chemicals. In milk, casein present so-called micelles (CMs). Based on rennet-induced aggregation, we developed process that can be applied micellar sustainable way without u...

The surfactant transfer in micellar solutions includes transport of all types of aggregates and the exchange of monomers between them. Such processes are theoretically described by a system containing tens of kinetic equations, which is practically inapplicable. For this reason, one of the basic problems of micellar kinetics is to simplify the general set of equations without loosing the adequa...

separation of polycyclic aromatic hydrocarbons was performed by rp-hplc using mixed micellar mobile phase. effect of temperature, types and amounts of coorganic solvent in mobile phase on efficiency, asymmetry factor and selectivity factor showed that the appropriate condition for separation of these compounds was 3% isopropanol (v/v) as co-organic solvent in mobile phase at 40°c. analysis of t...

We present a study of equilibrium chain-exchange kinetics of a well-defined model system for starlike polymeric micelles. The results show that the kinetics follows a logarithmic time dependence. The same feature has been confirmed for two other micellar systems. This is in sharp contrast to theoretical predictions and hints towards strongly coupled chain dynamics within the micellar cores indu...

Studies were carried out to test the hypothesis that abnormal bile salt metabolism (interruption of the enterohepatic circulation) is responsible for steatorrhea in patients with ileal disease and (or) ileectomy.Duodenal bile salt concentration after a single, standard meal eaten at 8 a.m. was measured in 8 patients with ileectomy steatorrhea and compared with 11 normal control subjects and 7 h...

Preparation of magnetitelmaghemite nanometric particles is reported from the precipitation of ferrous dodecyl sulfate micellar solution with methylamine. The size of nanocrystals is controlled by the micellar concentration and by temperature. It varies from 3.3nm to llnm. Magnetic properties are studied for various sizes of maghemite particles.
