摘要： An air-cooling system includes an evaporator adapted to cool an air and a reservoir for storing a liquid and providing the liquid to the evaporator. The air-cooling system also includes a pressure reducer system fluidly coupled to the evaporator and adapted to create a relatively low pressure inside the evaporator to facilitate a conversion of the liquid flowing through the evaporator into vapors. The pressure reducer system includes a liquid ejector having an inlet portion adapted to receive the liquid from the reservoir, a throat portion arranged downstream of the inlet portion and fluidly coupled to the evaporator and an outlet portion disposed downstream of the throat portion and configured to increase a pressure inside the liquid ejector. The pressure reducer system also includes a pump fluidly connected to the liquid ejector and the reservoir to supply the liquid from the reservoir to the liquid ejector.

摘要： The disclosure relates to laminate structures to cover or protect substrates or surfaces. The laminate structure comprises a support layer and a self-sterilizing/antimicrobial layer comprising a sulfonated polymer, capable of killing microbes within minutes and for an extended period of time. The sulfonated polymer has a sufficient degree of sulfonation to kill in less than 120 minutes at least 90% of microbes in contact with the surfaces, and for extended protection of the surfaces for at least one month. The laminate structure is particularly suitable for protecting high-touch surfaces such as door knobs, touch-screens, tables, as well as for use with facemasks, face shields, or as self-sterilizing wraps for surgical instruments and supplies. The laminates can also be used as garments or to cover/protect personnel having contagious diseases, etc., to decrease the transmission of microbes.

摘要： Disclosed herein is a styrenic block copolymer [A1-B1-C1], consisting essentially of polymer blocks A1, B1 and C1. A1 is a poly(para-alkylstyrene) block having a molecular weight from 1,000 to 60,000 g/mol. B1 is a hydrogenated polyisoprene block or a hydrogenated polybutadiene block having a molecular weight from 1,000 to 100,000 g/mol. C1 is a polystyrene block having a molecular weight from 1,000 to 100,000 g/mol; or a polymer block consisting essentially of polymerized styrene units, and hydrogenated butadiene and/or isoprene units, and having a molecular weight from 1,000 to 100,000 g/mol. Prior to hydrogenation, the block B1 has a vinyl content of 5-75 mol %; and the block C1 forms 1-80 wt % of the overall weight of the block copolymer. The selectively sulfonated forms of the copolymers are useful as high dielectric materials.

摘要： A process for a continuous condensation reaction with feedstocks derived from bio-renewable resources, e.g., pine chemical derived feedstock, is disclosed. The process employs at least a multi-stage mixing reactor, selected from any of a multi-stage continuous stirred tank reactor (CSTR), a multi-stage horizontal continuous stirred tank reactor (HCSTR), or a continuous oscillating baffle reactor (COBR). The multi-stage mixing reactors are provided with a plurality of baffles for creating a mixing in a number of stages or cells created by the baffles, allowing the condensation reaction to proceed at a production rate at least twice that of a batch process with reactors of equivalent volume. The feedstocks derived from bio-renewable resources is selected from gum rosin, wood rosin, tall oil rosin and mixtures thereof; and polymeric fatty acids derived from bio-renewable resources such as tall oil.

摘要： Disclosed herein is a copolymer concentrate in a bio-solvent that can be further diluted into a slurry composition. The bio-solvent facilitates the formation of a viscosified base fluid with the mixing being carried out in a short period of time and at ambient, providing a free flowing, pumpable, and dispersible slurry. The slurry is characterized as having excellent stability, maintaining suspension over a wide range of temperatures. In embodiments, the bio-solvent is selected from terpene and terpene-derivative-containing solvents, fatty acid alkyl esters, and mixtures thereof. The bio-solvent can be first mixed with a styrenic diblock copolymer to form a concentrate prior mixing with a hydrocarbon solvent, forming a viscosified base fluid for subsequent mixing with a water-soluble polymer to form the slurry. The bio-solvent can also be used to dilute the hydrocarbon solvent, prior to mixing with the styrenic diblock copolymer to form the viscosified base fluid.
