Abstract: The present invention provides polymersomes comprising amphiphilic block-copolymers and their use to quantify ammonia in samples (e.g., body fluid samples). More particularly, it provides a polymersome comprising (a) a membrane, which comprises a block copolymer of poly(styrene) (PS) and poly(ethylene oxide) (PEO), wherein the PS/PEO molecular weight ratio is higher than 1.0 and lower than 4.0; and (b) a core which encloses an acid and at least one pH-sensitive dye. Compositions, strips and kits comprising the polymersomes are also provided along with methods of quantifying ammonia in a sample using the polymersomes, compositions and kit.

Abstract: The present invention relates to articles comprising core shell liquid metal encapsulate networks and methods of using core shell liquid metal encapsulate networks to control AC signals and power. Such method permits the skilled artisan to control the radiation, transmission, reflection and modulation of an AC signal and power. As a result, AC system properties such as operation frequency, polarization, gain, directionality, insertion loss, return loss, and impedance can be controlled under strain.

Abstract: A process for forming an extruded composition using a wet-spin dry-jet technique including forming a dispersion dope by mixing phase change material with a first portion of solvent, and sonicating the mixture, forming a prime dope by combining a first portion of polymer and a second portion of solvent, forming an extrusion composition by combining the dispersion dope, the prime dope and a second portion of the polymer, rolling the extrusion composition, degassing the extrusion composition, extruding the extrusion composition through a spinneret, drying the extruded composition, and quenching the extruded composition. The weight fraction of the phase change material in the extruded composition can be greater than approximately 60%, and preferably greater than approximately 75%.

Abstract: A nozzle includes a nozzle body having a fluid passageway to which extension tubes are communicated. Each extension tube includes an end having an outlet port. The outlet ports are spaced from each other. An apparatus includes the nozzle, a fluid tank into which the extension tubes extends, a fluid shear device mounted in the fluid tank, and a temperature control system in which the fluid tank is mounted. A method includes filling a water phase fluid into the fluid tank. An oil phase fluid flows out of the nozzle body via the outlet ports. The water phase fluid is disturbed and flows out of the outlet ports to form semi-products of microparticles in the fluid tank. Each semi-product has an inner layer formed by the oil phase fluid and an outer layer formed by the water phase fluid. The outer layers of the semi-products are removed to form microparticles.
