  • Publication number: 20150148459
    Abstract: The deposition of graphene is accomplished by various techniques that result in a change of the graphene's solubility in the liquid medium. The solubility change enables the deposition of the graphene onto the substrate. Once the graphene is deposited onto the substrate, the at least partially coated substrate may be separated from the liquid medium. The substrates may then serve as a carrier to deliver the graphene to a desired application.

    Abstract: Various processes and methods are disclosed for incorporating polyvinyl alcohol additives into products. In one embodiment, polyvinyl alcohol particles are dissolved in a solvent without the use of external heat to form a polyvinyl alcohol solution for incorporation into a product. In an alternative embodiment, polyvinyl alcohol particles are directly incorporated into a starch-based adhesive composition. Through the processes of the present disclosure, solid polyvinyl alcohol particles can be delivered directly to a manufacturing facility where the product that incorporates the polyvinyl alcohol additive is being made or formulated. In this manner, since the polyvinyl alcohol particles are not predissolved, the costs associated with shipping and transporting the polyvinyl alcohol product are greatly reduced.

    Abstract: Components of an unmanned undersea vehicle are inspired by jellyfish that uses its flexible body and tilt sensing to achieve efficient swimming and turning. A tilt sensor, based on a statocyst, has a metal ball in a chamber lined with resistors. The tilt is sensed in accordance with which resistors the ball contacts. A composition of polyvinyl alcohol hydrogel with ferritin particles dispersed therein mimics the qualities of a jellyfish's mesoglea.
