摘要： A dehumidification system for removing water vapors from an air is disclosed. The system includes a dehumidification core defining an air channel and at least one vapor channel separated from the air channel by a membrane to facilitate a removal of moisture from the air flowing through the air channel and is selectively permeable to water and water vapor and impermeable to air. The dehumidification system further includes a water ejector having a throat portion fluidly coupled to the vapor channels and adapted to create a relatively lower pressure of water vapor within the vapor channels than in the air channel The water ejector also includes an outlet portion disposed downstream of the throat portion and configured to increase the pressure of water to facilitate a condensation of the water vapors received from the vapor channels.

摘要： A frequently-touched surface for use by multiple users includes a surface protected by a laminate structure. The laminate structure includes a self-sterilizing sulfonated polymeric outer layer, sulfonated to a certain % to kill at least 95% microbes within 30 minutes of contact. The self-sterilizing sulfonated polymer layer can be applied to the frequently touched surface by any of coating, lamination, and spraying. The sulfonated polymer in embodiment is selected from perfluorosulfonic acid polymers, polystyrene sulfonates, sulfonated block copolymers, sulfonated polyolefins, sulfonated polyimides, sulfonated polyamides, sulfonated polyesters, sulfonated polysulfones, sulfonated polyketones, sulfonated poly(arylene ether), and mixtures thereof. The sulfonated polymer has a degree of sulfonation of at least 10%.

摘要： An article with self-disinfecting and anti-fog properties. In embodiments, the article is a face shield having a transparent substrate configured to extend facing at least a portion of a face of a wearer, and has a first surface adapted to be disposed facing the face of the wearer and second surface disposed opposite to the first surface. The face panel is protected by a sulfonated polymeric layer on the second surface, for killing at least 95% microbes within 30 minutes of contact. The sulfonated polymeric is sufficiently or selectively sulfonated to contain from 10-100 mol % sulfonic acid or sulfonate salt functional groups based on the number of monomer units, for killing at least 99% of microbes within 5 minutes of coming into contact with the face panel. The sulfonated polymeric layer has a Tfog of >15 minutes.

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.
