  • Publication number: 20200239670
    Abstract: Closed cell chitin foam is provided. The closed-cell chitin foam composition does not absorb water, is biodegradable, and is mechanically characterized by a density range of 16 to 800 kg/m3, closed-cell pore sizes ranging from 50 microns to 1 mm, an elastic modulus of 3 to 175 MPa, and a tensile strength of 0.15 to 6.5 MPa. The chitin is at least 70% acetylated. In one aspect, the foam is enclosed in a shell e.g. in the form of a surfboard. Chitin foam according to this invention is fully biodegradable. The chitin foam overcomes the current problems with foams that contain polyurethane and polystyrene, and which are manufactured from petroleum-based sources. Petroleum based foams are not renewable, have an adverse impact on our environment, and pose significant health hazards to those who manufacture them. The chitin foam with its water-based manufacturing process and naturally sourced chitin, solves these problems.

  • Publication number: 20170047513
    Abstract: Disclosed herein is a memory device operating based on proton conduction between a source electrode and a drain electrode through a proton-conducting layer. As the memory device operates, protons from the source migrate through the proton-conducting layer and into the drain electrode. The memory device exhibits memory, in the form of changing net conductivity, based on the amount of protons conducted from source to drain. The memory device can be reset by regenerating the source electrode (e.g., through electrical or chemical action). The memory device can be incorporated into an integrated circuit as a memory element. Related methods of using the memory device are also disclosed.

  • Publication number: 20150305739
    Abstract: The present invention relates generally to wound closure devices comprising one or more microstructures. The devices are designed such that the microstructures are able to grip the skin or tissue surrounding a wound, optionally closing the wound, or securing the tissue or skin in place. Also provided are wound closure systems that comprise one or more microstructure wound closure devices along with other components, such as protective covers and wound healing therapeutics. A variety of packaging specifications are disclosed, as is a dispenser apparatus configured to enable simple one-handed application of the wound closure devices. Methods described herein provide for the closure of various wounds with the wound closure devices and systems.

  • Patent number: 9153437
    Abstract: Methods for forming inorganic nanostructures are provided. The methods create the inorganic nanostructures by positioning a writing electrode (e.g., a conductive “stamp”) spaced nanometers above a substrate such that a precursor is intermediate the two. Applying an electric field, a voltage bias, an ionic current, or an electronic current between the writing electrode and the substrate converts the precursor into an inorganic solid material (e.g., a semiconductor such as silicon or germanium) in the area of the writing electrode.
