Exciton dispersion in molecular solids
Journal of Physics: Condensed Matter, 2015 The investigation of the exciton dispersion (i.e. the exciton energy dependence as a function of the momentum carried by the electron-hole pair) is a powerful approach to identify the exciton character, ranging from the strongly localised Frenkel to the delocalised Wannier-Mott limiting cases.

Exciton character in picene molecular solids
, 2011 We have studied the low-energy electronic excitations of solid picene at 20 K using momentum dependent electron energy-loss spectroscopy. Our results demonstrate the presence of five excitonic features below the transport energy gap of picene, which all ...

Characterization of olanzapine-solid dispersions.
Iranian journal of pharmaceutical research : IJPR, 2011 To enhance the aqueous solubility of olanzapine by using the Solid dispersion technique. Solid dispersions of olanzapine were prepared by the dispersion method using using PGS and SSG as carriers. Drug-carrier ratios such as 1 : 1, 1 : 2, 1 : 4, 1 : 6, 1: 8 and 1 : 10 were tried for optimization.
