BACKGROUND/AIMS High viscosity silicone oils are used as tamponade agents to increase the resistance to emulsification; however, this makes the oils more difficult to inject. Increasing the extensional viscosity is one way to reduce emulsification. This study aimed to evaluate how silicone oils with increased extensional viscosity behave in terms of their ease of injection. METHODS The shear ...
The effects of blend ratio and drug loading content of poly(D,L-lactide) (PDLL)/stearic acid blends on microparticle characteristics and drug release behaviors were evaluated. The blend microparticles were prepared by an oil-in-water emulsion solvent evaporation method for drug delivery of a poorly water-soluble model drug, indomethacin. The microparticles were characterized using a combination...
Blending Nomex® with cotton improves its affordability and serviceability. Because cotton is a highly flammable fiber, Nomex®/cotton blend fabrics containing more than 20% cotton require flame-retardant treatment. In this research, combination of a hydroxyl functional organophosphorus oligmer (HFPO) and 1,2,3,4-butanetetracarboxylic acid (BTCA) was used for flame retardant finishing of the 65/3...
Urea removal is one of the biggest challenges in dialysate regeneration Wearable Artificial Kidney (WAK) devices. In this work, a new Mixed Matrix Membrane (MMM) developed for urea WAK applications. The MMM consists polystyrene-based ninhydrin particles within polyethersulfone/polyvinylpyrrolidone polymer blend matrix. prepared via dry-wet spinning technique and characterized terms its morpholo...
