Disintegration Properties and Drug Release Profiles of Chondroitin Sulfate Films

Yoshifumi Murata, Yukako Maejima, Chieko Maida, Kyoko Kofuji

Abstract: Film dosage form (FD) prepared using water-soluble polymers is an excellent technique by which drugs can be delivered to local disease sites. In this study, FD was prepared with the sodium salt of chondroitin sulfate (CHS), a natural polysaccharide, by the casting method. The disintegration profile of FD was assessed and th [...] Read more.

An Innovative Self-Weld Framework of Microscale Copper Phthalocyanine

Kai-Wei Liu, Jia-Lin Hsu

Abstract: Microscale frameworks were obtained by copper phthalocyanine-sulfuric acid blends in our proposal. In the frameworks, crystals and unoccupied space are at an equivalent-size level. During dehydration, wires spontaneously weld at their contacts to construct a framework. Dehydrated and post-annealed frameworks have morphologi [...] Read more.

Observation of Calcium-Alginate Gel with Micrometer-sized Network Structure

Minoru Aoyagi, Takahiro Ueno

Abstract: The micrometer-sized network structure of a calcium-alginate hydrogel, which was synthesized from sodium alginate, calcium sulfate dihydrate, trisodium phosphate 12-hydrate, glycerol, and water, was observed using an optical microscope, cryogenic-scanning electron microscope, and an energy-dispersive X-ray spectrometer. For [...] Read more.

Electrospun silver modified polyarylonitrile-activated carbon composite fibers: Methylene blue adsorption and antibacterial activity

Thinnakorn Magdee, Darunee Aussawasathien, Sa-Nguansak Sriphalang, Kittipong Hrimchum

Abstract: Silver modified polyacrylonitrile-activated carbon (Ag-PAN-AC) composite fibers containing various AC concentrations were prepared by using an electrospinning process. Ag-PAN nanoparticles were initially prepared via in-situ reduction of silver nitrate using hydrazinium hydroxide as a reducing agent. The influence of AC con [...] Read more.

Low Density Polyethylene-Activated Carbon Composite Foams: Preparation and Properties

Darunee Aussawasathien, Kotchaporn Jariyakun, Thongchai Pomrawan, Kittipong Hrimchum, Rungsima Yeetsorn, Walaiporn Prissanaroon-Ouajai

Abstract: Low density polyethylene (LDPE) containing activated carbon (AC) was foamed with azodicarbonamide (ADC) through an extrusion process. The effects of ADC and AC contents on the cellular structure, void fraction, density, thermal and mechanical properties, and crystallinity of composite foams were investigated. The density of [...] Read more.

Potentiostatic electrosynthesis of cerium conversion coatings on AA2024-T3 aircraft alloy in diammonium pentanitrocerate solutions

S. Kozhukharov, Christian Girginov

Abstract: Cerium conversion coatings (CeCC) have been synthesized for corrosion protection of AA2024-T3 aircraft alloy through application of potentiostatic regime in aqueous solutions of diammonium pentanitrocerate - (NH4)2Ce(NO3)5. This cerium compound is used for first time for this purpose. The impact of the following deposition [...] Read more.

Viscosity of CNT Loaded Epoxy Resin

Hector Estrada, Luke S. Lee, Jonathan Trovillion, Maciej Tusz, Ashok Kumar, and Larry D. Stephenson

Abstract: The processing of fibre reinforced carbon nanotube (CNT) loaded polymer composites (nanocomposites) requires that CNTs be mixed (or loaded) into the polymer prior to impregnating the fibres to fabricate a nanocomposite. The fabrication process uses vacuum-assisted resin transfer moulding (VARTM), which is complicated due to [...] Read more.
