Model of micellar structure tested by SANS and SAXS (from a Kratky camera) in cesium dodecyl sulfate solution

Article Abstract:

Small-angle neutron-(SANS) and X-ray-scattering (SAXS) patterns obtained at 40 degree C from 0.0729 m D2O solution of cesium dodecyl sulfate (CsDDS) is evaluated in terms of the conventional two-shell model, a three-shell model created for demonstration purposes. Findings suggest that the most reliable information on the aggregate structure is obtained when fitting the four-component model to the combined SANS + SAXS patterns.

Supramolecular chirality of achiral TPPS complexed with chiral molecular films

Article Abstract:

Studies done on the fabrication and supramolecular chirality of complex multilayer films of tetrakis(4-sulfonato-phenyl)-porphine (TPPS) and long-chain enantiomers of tryptophan derivatives (D-Trp or L-Trp) are reported. Complex multilayer films of TPPD and chiral Trp amphiphiles can be formed by in situ or ex situ adsorption and it was observed that TPPS could form J aggregates and show chirality in both types of multilayer films.
