摘要： Methods and systems are provided for recovering an organic solvent from a waste sludge generated during formation of a polyarylene sulfide. Methods include combining the waste sludge with an anti-solvent to create a dispersion, which includes a solid phase that includes a substantial portion of the impurities of the polyarylene sulfide formation and a liquid phase that contains the anti-solvent and organic solvent employed during formation of the polyarylene sulfide. The liquid phase is separated from the solid phase and then subjected to a distillation process to separate the organic solvent from the anti-solvent. Methods can also include forming the polyarylene sulfide by a polymerization process and thereafter purifying a slurry of the polyarylene sulfide. A liquid washing product is formed as a result of the purification process, which can be subjected to a distillation process that forms an organic solvent-rich stream and the waste sludge.

摘要： A microneedle assembly that is capable of transdermal delivery of a drug compound, such as a vaccine, (e.g., vaccine) across a dermal barrier of a subject (e.g., human), and/or detecting the presence of an analyte in the subject is provided. The microneedle assembly comprises a plurality of microneedles arranged on a support that each contain a tip and base, one or both of which are formed from a polymer composition that includes a liquid crystalline polymer. By selectively controlling the specific components of the polymer composition, as well as their relative concentration, the resulting microneedles may exhibit a high degree of physical alignment, which can help ensure better performance during use of the microneedle assembly.
