One type of composite nanofibers reported so far are prepared by multiple-jet electrospinning (3), (4), mainly because a cosolvent is hard to be found for each component.
Through the use of supercritical and near-critical carbon dioxide with small molar quantities of a cosolvent (SuperFluids(TM)), Aphios has crystallized the anticancer drug paclitaxel (molecular weight 854) in considerably larger crystal size, improved morphology, higher purity and improved yields than can be achieved by conventional organic phase techniques.
These results point to the idea that adhesion to PVDF finishes can be significantly enhanced by choosing a topcoat coalescent or cosolvent which can effectively cause some softening or plasticization of the substrate.

Solubilization behavior of poorly soluble drugs with combined use of gelucire 44/14 and cosolvent.
However, since there have not been many reports upon utilization of solvent-co-solvent mixture approach for modifying the active layer (P3HT/PCBM) morphology in an inverted device so, we considered in detail two processing techniques for the aforesaid cosolvent addition (before spin coating step) for active layer preparation in the inverted device.
Even though a part of the bark is extracted and, as a result, the total energy flow to the boiler is decreased, the cosolvent losses to the bark and the drying will increase the heat content of the extracted bark.
ethanol, n-propanol) is typically used as a cosolvent to enhance the pot life of the formulation.
