Strategies to Improve the Lipophilicity of Hydrophilic Macromolecular Drugs
Advanced Healthcare Materials, EarlyView.Hydrophilic macromolecular drugs can be successfully lipidized by covalent attachment of lipids, by hydrophobic ion pairing with negatively or positively charged surfactants, and by dry or wet reverse micelle formation. Lipophilicity enhancement of hydrophilic macromolecules has several benefits including stability and bioavailability improvement ...

Process for purification of waste water produced by a Kraft process pulp and paper mill [PDF]
, 1979 The water from paper and pulp wastes obtained from a mill using the Kraft process is purified by precipitating lignins and lignin derivatives from the waste stream with quaternary ammonium compounds, removing other impurities by activated carbon produced
