The abuse of prescription opioid drugs is a well-documented and very serious problem. One of the typical first steps an abuser will take is to manipulate a tablet into to a fine powder. To deter this behavior, formulators use crush-resistant technologies like polyethylene oxide (PEO). When heat-treated, PEO creates a hard, flexible tablet that cann...
In the current study, we present methods of sodium hyaluronate, also denoted as hyaluronan (HA), nanofiber fabrication using a direct-current (DC) electric field. HA was spun in combination with poly(vinyl alcohol) (PVA) and polyethylene oxide (PEO) and as a pure polymer. Nonaggressive solvents were used due to the possible use of the fibers in lif...

Reconstruction of the bladder wall plays an important role in improving its function in patients with urinary bladder dysfunction. Tissue engineering has been trying to introduce biocompatible nanofibers as scaffolds for bladder wall matrix substitutes. In this study a composite nanofibrous scaffold was fabricated from polyacrylonitrile (PAN) and p...
Hydrogel as a good water absorbent has attracted great research interest. A series of hydrogel based on polyethylene oxide (PEO) and acrylic acid (AAc) was prepared by applying gamma radiation with variation in the concentration of acrylic acid. Fourier transform infrared (FTIR) and scanning electron microscopy (SEM) were used to characterize the P...
Casein, a natural protein, has been used as a biopolymer-based resource for producing fiber. This fiber provides high comfort properties with a pH close to human skin. This study focused on evaluating the production feasibility of casein nanofiber twisted yarn with the highest protein content in the hybrid yarn, obtaining suitable spinning conditio...

Rheological properties of mixtures of dilute and moderately concentrated aqueous solutions of carboxymethyl cellulose with various degrees of ionization and polyethylene oxide were studied. The range of compositions in which the viscosity of dilute solutions of the polymer blends shows negative deviation from the calculated additive values becomes ...
C, and it showed high activities for Heck reactions between aryl iodides and butyl acrylates and could be recycled for five times. The correlations between the microstructure and properties of the [email protected]/PEO catalytic composites were discussed.
85% alginate. This study shows that RSM can be used to design nanofibers with optimal alginate and co-polymer contents to provide efficient scaffold material for regenerative medicine.
