Gas Jet Process for Production of Sub-micron Fibers
… The approach yielded nanofibers from blends of polyvinylacetate and polyvinylpyrrolidone with diameters below 500 nm exhibiting several morphological forms after phase separation of the polymers including interpenetrating, bi-lobal, and core-shell.The gas jet method was also used to produce …

Development and manufacture of novel amorphous Itraconazole drug products using quality by design principles
… acetate succinate (HPMCAS) and polyvinylacetate (PVA) were screened using group contribution theories developed by Fedors, Van Krevelen and Just-Breitkreutz. The difference in the solubility parameter (Δδ) indicated better miscibility for the ITZ-KOL, ITZ-HPMCAS systems (< 5 …

Surface Characterization of Siloxane, Silsesquioxane, and Maleic Anhydride Containing Polymers at Air/Liquid Interfaces
Langmuir-monolayer formation at the air/water interface (A/W) can be achieved by spreading amphiphilic molecules on a liquid subphase and compressing them into an ordered arrangement. The use of the Langmuir-Blodgett technique (LB) to prepare ultra thin films on solid surfaces from monolayers at …
