Micropolarity and order in the reverse micelles of L62 and L64 pluronic copolymers, as studied by molecular probe techniques
Article Abstract:
An investigation on the reverse micelles of triblock copolymers poly(ethylene oxide)-block-poly(propylene oxide)-block-poly-(ethylene oxide) EO6PO36EO6 (Pluronic L62) and EO13PO30EO13 (Pluronic L64) in ternary and binary systems with different water contents was conducted using fluorescence, absorption and spin probe techniques. The results gave complementary and concordant conclusions regarding micellization, hydration and microviscosity in various micellar zones.

Highly sensitive detection of processes occurring inside nanoporous anodic alumina templates: a waveguide optical study
Article Abstract:
Nanoporous anodic alumina films as planar optical waveguids are applied and the changes in the effective dielectric constants of these films due to various processes occurring in the pores are examined. The conclusion states that porous anodic alumina films can be employed as deposition templates and as highly sensitive detectors of process within the pores.

Structural characterization of micellar aggregates in sodium dodecyl sulfate/aluminium nitrate/urea/water system in the synthesis of mesoporous alumina
Article Abstract:
The formation mechanism of hexagonal alumina using sodium dodecyl sulfate as template by using NMR self-diffusion and spin and fluorescence probe techniques is described. A model of precipitation is developed based on the analogy with the formation of the hexagonal crystalline Al-DS precipitate in the ternary SDS/SL(NO3)/water system.
