Dielectric dispersion interpretation of single enzyme dynamic disorder, spectral diffusion, and radiative fluorescence lifetime
Article Abstract:
A formulation is developed that is based on the measurable dielectric dispersion of enzymes in order to estimate fluctuations in electrostatic interaction energy on time scales as long as milliseconds to seconds at a local site in enzymes. The experimental results on the autocorrelation function of the fluctuations of catalysis rate are compared with the calculations by using the dielectric dispersion formulation.

Hexagonal close packing of nonionic surfactant micelles in water
Article Abstract:
A detailed structural study of the hexagonal close packed micellar phase, observed in the binary mixtures of nonionic surfactant [C.sub.12]E[O.sub.8] and water, is presented. The analysis has indicated that the reconstructed electron density map of the phase shows perfectly spherical micelles.

Micelle-Enhanced dissociation of a Ru cation/DNa complex
Article Abstract:
Anionic surfactant monomers have a large catalytic effect on the dissociation rate constant of a Ru(sub 2)(super 4+)-DNA complex, an effect further enhanced upon exceeding the critical micelle concentration. The results show that the catalytic effect is primarily nonelectrostatic in nature.
