We describe, for the first time, hydrogel-forming microneedle arrays prepared from "super swelling" polymeric compositions. We produced a microneedle formulation with enhanced swelling capabilities from aqueous blends containing 20% w/w Gantrez S-97, 7.5% w/w PEG 10,000 and 3% w/w Na2CO3 and utilised a drug reservoir of a lyophilised wafer-like design.(More)
A previously developed mathematical model for ethylene polymerization in a fluidized bed reactor was used to investigate the process static and dynamic behavior. The static analysis determined optimal operating conditions at which the monomer conversion can be increased to 25% per pass. However, this optimal operating point was shown to be unstable and thus(More)
BACKGROUND High Density Polyethylene (HDPE) is one of the most often used polymers in biomedical applications. The limitations of HDPE are its visco-elastic behavior, low modulus and poor bioactivity. To improve HDPE properties, HA nanoparticles can be added to form polymer composite that can be used as alternatives to metals for bone substitutes and(More)
Large amounts of low-quality dates produced worldwide are wasted. Here, highly concentrated fructose syrups were produced via selective fermentation of date extracts with Saccharomyces cerevisiae. Syrups with 95.4–99.9 % (w/w) fructose yields were obtained from date extracts having an initial sugar range of 49–374 g/l without media supplementation; the(More)
