  • SOLID-STATE COPPER(I) SORBENTS FOR OLEFIN SEPARATIONS
    Publication number: 20210387134
    Abstract: Disclosed herein is a process for separating a hydrocarbon feed gas mixture comprising constituents including ethylene to produce a separated ethylene product. The disclosed process employs a solid-state ethylene sorbent and temperature and/or pressure swing adsorption and membrane separation and demonstrates a methodology to reduce the net heat of reaction during the adsorption of ethylene onto an adsorbent.

  • Thermoplastic elastomer hydrogels
    Patent number: 10428185
    Abstract: Provided herein is a block copolymer hydrogel, comprising a glass formed from a dry blend of polystyrene-poly(ethylene oxide) diblock copolymer (SO) and polystyrene-poly(ethylene oxide)-polystyrene triblock copolymer (SOS) in a molar ratio from between 95:5 and 1:99 SO/SOS and a liquid medium at a concentration between about 32:1 and about 2:1 liquid medium/SO—SOS by weight. The block copolymer hydrogel has a fatigue resistance to at least 500,000 compression cycles. Also provided are methods for forming the hydrogel.
