in this study, aggregation behavior of a water soluble cationic metalloporphyrin, meso-tetrakis (2,3,5,6-tetrafluoro-n,n´,n´´-trimethyl ammonium phenyl) porphyrin nickel(ii) [ni(ii)(tf4tmapp)]4+ is investigated in 5 mm aqueous phosphate buffer of ph 7.0 at 25.0 °c and various ionic strengths using optical absorption and resonance light scattering spectroscopic methods. the results suggest that ...

By studying cross correlations in the intensity of light scattered by a fluid sample in different directions at different times, it is possible to measure the dynamic scattering function S(k,t) for the fluid. The multiple scattering contribution to the time-dependent cross correlations is very substantially less than the multiple scattering contribution to S(k,t) as obtained by a conventional s...

The formation of spherical micelles in aqueous solutions of poly(N-methyl-2-vinyl pyridinium iodide)-blockpoly(ethylene oxide), P2MVP-b-PEO and poly(acrylic acid)-block-poly (vinyl alcohol), PAA-b-PVOH has been investigated with light scattering-titrations, dynamic and static light scattering, and H 2D Nuclear Overhauser Effect Spectroscopy. Complex coacervate core micelles, also called PIC mic...

Dynamic light scattering is a well established technique currently used to determine the average hydrodynamic diameter of nanometer to micrometer particles in suspension. A simple, modified experimental setup and the software to process experimental data are presented in this paper. Results on monitoring the time variation of the average diameter of the particles in suspension are presented and...

We elucidated the light-matter interaction of individual ZnO NRs with a monochromatic beam of linearly polarized light that scatters elastically from the ZnO NRs by performing forward scattering and back-aperture imaging in a dark-field setting. We precisely controlled the electric field vector of the incident light and the NR orientation within the plane of light interaction during both modes ...
