  • Patent number: 11739010
    Abstract: A method of forming an electrode for capacitive deionization includes depositing an slurry onto a substrate, wherein the slurry comprises a porous material, a first crosslinkable hydrophilic polymer, and a crosslinker for the first crosslinkable hydrophilic polymer; annealing the slurry deposited on the substrate to create a crosslinked porous layer on the substrate; depositing an solution comprising an ion-exchange material, a second crosslinkable hydrophilic polymer, and a crosslinker for the second crosslinkable hydrophilic polymer onto the crosslinked porous layer; and optionally annealing and/or drying the solution on the crosslinked porous layer.
    Type: Grant

  • Publication number: 20210293741
    Abstract: An electrode includes an electrically conductive substrate with a coating containing boron-doped diamond (BDD) nanoparticles. Fabricating the electrode can include dispersing BDD nanoparticles in a solvent to yield a suspension, coating a conductive substrate with the suspension, and drying the suspension to yield the electrode. In some cases, fabricating the electrode includes combining BDD nanoparticles with a polymeric resin precursor to yield a mixture including a metal oxide, coating a conductive substrate with the mixture to yield a coated substrate, and calcining the coated substrate to yield a metal oxide coating including BDD nanoparticles.

  • Patent number: 9625752
    Abstract: Responsive, biocompatible substrates are of interest for directing the maturation and function of cells in vitro during cell culture. This can potentially provide cells and tissues with desirable properties for regenerative therapies. The present disclosure provides a scalable approach to attach, align and dynamically load cells on responsive liquid crystal elastomer (LCE) substrates. Monodomain LCEs exhibit reversible shape changes in response to cyclic stimulus, and when immersed in an aqueous medium on top of, for example, resistive heaters, shape changes are fast, reversible and produce minimal temperature changes in the surroundings.

  • Patent number: 9260570
    Abstract: In some embodiments, the present disclosure provides methods of strengthening liquid crystal elastomers. In some embodiments, such methods include a step of placing the liquid crystal elastomer in an environment that applies dynamic stress to the liquid crystal elastomer. In further embodiments, the methods of the present disclosure also include a step of providing liquid crystal elastomers for placement in an environment that applies dynamic stress. In some embodiments, the liquid crystal elastomer is in a nematic phase before or during the application of dynamic stress. In some embodiments, the application of dynamic stress enhances the stiffness of the liquid crystal elastomer by more than about 10%. Further embodiments of the present disclosure pertain to liquid crystal elastomers that are made by the methods of the present disclosure.
