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...
Biocide-loaded storm water either infiltrates into the soil around houses29or is directed into SIS such as swales and swale-trench-systems. Together with local infiltration of storm water, the purpose of SIS is to reduce moderate contaminant load30,31. Reviews of17and32showed that this may be ...
