  • Patent number: 12018443
    Abstract: A flexible runway mat system, including a plurality of base platforms, each respective base platform having a first pattern of phase transforming columns and voids extending from a respective flat member, and a plurality of plane-engaging runway platforms, each respective plane-engaging runway platform having a second, reversed pattern of phase transforming columns and voids extending from a respective flat member such that each respective plane-engaging runway platform is lockingly engagable to a respective base platform to yield a landing segment with parallel top and bottom flat members. Each respective phase transforming column is further comprised of a plurality of stacked operationally connected phase transforming cellular members. Each respective phase transforming cellular member can shift from a first stable configuration to a second stable configuration in response to an applied load.

  • Publication number: 20220401207
    Abstract: Stents comprising a first region and a second region are provided, where at least the second region comprises one or more phase transforming cellular materials configured to move the outlet between an open configuration and a closed configuration in response to certain triggers. Such stents can also comprise one or more analog for a shape memory alloy (ASMA) unit cells on an inner surface of the first region such that, in response to resistive forces, the ASMA unit cells exert controllable motion to clear the stent. Methods of treatment of cancer, jaundice, and other diseases are also provided.

  • Publication number: 20160347661
    Abstract: The invention provides a cement paste composition comprising cement, cellulose nanocrystals, and optionally water. The cellulose nanocrystals can be present in an amount sufficient and effective to increase the flexural strength of cured cement prepared from the cement paste composition. The cellulose nanocrystals can also be present in an amount sufficient and effective to increase the workability of a cement paste prepared from the cement paste composition. The invention further provides a water reducing additive that reduces the amount of water required for desired workability of a cement composition. Use of the presence of the cellulose nanocrystals also results in an increased degree of hydration and cumulative heat evolution in comparison to a corresponding composition without the cellulose nanoparticles, thereby resulting in a higher total cure of the cement paste composition upon curing.
