Polymers and drugs are dissolved in a polar, water-miscible solvent such as acetone, acetonitrile, ethanol, or methanol. The solution is then poured in a controlled manner (i.e. drop-by-drop addition) into an aqueous solution with surfactant. Nanoparticles are formed instantaneously by rapid ...
per cent of the monomers have polymerized, and thereafter adding during the polymerization one or more quaternary ammonium monomers as referred to above (which may be the same as or different from any such monomers previously used) and one or more water-miscible organic solvents in sufficient ...
such as those used in facade paints to suppress algae and fungal growth and washed off by heavy rainfall. Their retention in storm water infiltration systems (SIS) depends, in addition to their molecular properties, on chemical properties and structure of the integrated soil layer. These soil pro...
and a hormone (TRH) that releases thyreotropin or its derivatives as an active ingredient, which are first dissolved in a mixture that consists of acetonitrile/ethanol and optionally water, or only acetonitrile, or that consists of acetonitrile and aqueous gelatin, or of dichloromethane and ...
solid substances, while the biocides were already dissolved in acetonitrile by the manufacturer. UR and SRB solutions were stored in amber glass bottles and wrapped with aluminum foil to prevent photolytic decay. The measured initial concentrations only slightly deviated from the intended concentrations ...
