  • Publication number: 20240133479
    Abstract: An electromagnetic valve and an air conditioning system are provided. The electromagnetic valve includes a valve bonnet and a valve seat. The valve bonnet includes a large-diameter section and a small-diameter section, the small-diameter section extends into a mounting groove and is affixed to a groove wall of the mounting groove, and the large-diameter section abuts against the valve seat. A first sealing surface is formed by the large-diameter section abuts against the valve seat, and a second sealing surface is formed by the small-diameter section is affixed to the groove wall of the mounting groove. The valve bonnet and the valve seat are connected in a hard sealing connection manner at the first sealing surface, and the valve bonnet and the valve seat are connected in a soft sealing connection manner at the second sealing surface.

  • Publication number: 20220395584
    Abstract: Chitosan-nucleic acid polyplex compositions containing a reversibly bound polymer coat comprising linear block copolymers with a polyanionic anchor region and at least one polyethylene glycol tail region are described herein. In some cases, the compositions exhibit improved stability and/or mucosal diffusion as compared to uncoated particles. In some cases, the reversibly bound polymer coat does not interfere with, or enhances, transfection of target cells or tissues as compared to uncoated particles.
