Release Kinetics Model Fitting of Drugs with Different Structures from Viscose Fabric.

(1) Background: It is simpler and more environmentally friendly to use supercritical CO fluid technology to process skincare viscose fabrics. Therefore, it is significant to study the release properties of drug-loaded viscose fabrics to choose suitable skincare drugs. In this work, the release kinetics model fittings were investigated in order to clarify the release mechanism and provide a theoretical basis for processing skincare viscose fabrics with supercritical CO fluid.

A novel and green method for recycling of waste feather for down via flash explosion with supercritical carbon dioxide.

Millions of tons of feather are produced worldwide each year and considered as a solid waste owing to technical or cost constraints to provide valuable functional characteristics. In this study, a novel and ecofriendly method to recycle waste feather and obtain a type of explosion down via flash explosion with a supercritical fluid of carbon dioxide (SCF-CO) was developed for the first time. The effects of flash explosion parameters on the structures and properties of feather were explored by orthogonal experiments.

Resveratrol-Loaded Diacetate Fiber by Supercritical CO Fluid Assisted Impregnation.

(1) Background: Supercritical CO fluid (SCF-CO)-assisted impregnation presents advantages on loading active drugs to polymer substrates, since it enables the realization of a drug-loaded polymer without any solvent residue. Besides, CO gas and drugs can be recycled and utilized again. Resveratrol-loaded diacetate fiber by SCF-CO-assisted impregnation was done to give diacetate fiber biological activity function for enhancing its added value.

Flame retardant vinylon/poly(m-phenylene isophthalamide) blended fibers with synergistic flame retardancy for advanced fireproof textiles.

Superior flame retardant textiles are urgently needed to address high fire and heat risks. This study provides a simple and effective strategy to improve the flame retardancy of textiles through a synergistic effect between the blended fibers, and a system with synergistic in flame retardant vinylon (FRV)/poly(m-phenylene isophthalamide) (PMIA) blended fibers is discovered. The FRV/PMIA 50/50 exhibits a much higher time to ignition and a lower peak heat release rate than those of the neat components, indicating a synergistic flame retardancy between constituents.

Controllable synthesis, morphology evolution and electrochemical properties of LiFePO4 cathode materials for Li-ion batteries.

Monodispersed LiFePO4 nanocrystals with diverse morphologies were successfully synthesized via a mild and controllable solvothermal approach with a mixture of ethylene glycol and oleic acid as the solvent. Morphology evolution of LiFePO4 nanoparticles from nanoplates to nanorods can be simply realized by varying the volume ratio of oleic acid to ethylene glycol. Moreover, the mechanism of competitive adsorption between ethylene glycol and oleic acid was proposed for the formation of different morphologies.

Prediction and measurement of the electromagnetic environment of high-power medium-wave and short-wave broadcast antennas in far field.

With the increasing city size, high-power electromagnetic radiation devices such as high-power medium-wave (MW) and short-wave (SW) antennas have been inevitably getting closer and closer to buildings, which resulted in the pollution of indoor electromagnetic radiation becoming worsened. To avoid such radiation exceeding the exposure limits by national standards, it is necessary to predict and survey the electromagnetic radiation by MW and SW antennas before constructing the buildings. In this paper, a modified prediction method for the far-field electromagnetic radiation is proposed and successfully applied to predict the electromagnetic environment of an area close to a group of typical high-power MW and SW wave antennas.
