A new approach of improving drug dissolution properties is described. This method exploits the property of a carrier owing to the hydrotalcite-type anionic clays (HTlc). HTlc is an inorganic layered solid that lodges anionic compounds among its layers. As HTlc dissolves at acidic pH values (pH < 4),
A new enzyme stabilization method is proposed which is associated with dynamical immobilization within an unstirred ultrafiltration membrane reactor. Upon injection of suitable amounts of macromolecular solutions, the very polarization phenomena that yield the immobilization produce high macromolecu
## Abstract The COSMOβRS method, originally developed for the prediction of liquidβliquid and liquidβvapor equilibrium constants based on quantum chemical calculations, has been extended to solid compounds by addition of a heuristic expression for the Gibbs free energy of fusion. By this addition,
