  • Patent number: 11085422
    Abstract: Yarn energy harvesters containing conducing nanomaterials (such as carbon nanotube (CNT) yarn harvesters) that electrochemically convert tensile or torsional mechanical energy into electrical energy. Stretched coiled yarns can generate 250 W/kg of peak electrical power when cycled up to 24 Hz, and can generate up to 41.2 J/kg of electrical energy per mechanical cycle. Unlike for other harvesters, torsional rotation produces both tensile and torsional energy harvesting and no bias voltage is required, even when electrochemically operating in salt water. Since homochiral and heterochiral coiled harvester yarns provide oppositely directed potential changes when stretched, both contribute to output power in a dual-electrode yarn.

  • Patent number: 10343921
    Abstract: A method for preparing fluorinated graphene nanoribbons by using fluorine gas as a fluorine source, which includes a step of: fluorinating anhydrous carbon nanotubes in a fluorine gas atmosphere under a pressure of ?0.07˜0 MPa and a temperature of 280˜450° C. to obtain the fluorinated graphene nanoribbons. The method provided is operationally simple, and has a wide variety of raw material sources, low cost, and high production which can reach up to tens of milligrams and even up to hundreds of grams; moreover, the method has simple post-treatment, and can produce fluorinated graphene nanoribbons by a one-step reaction. The prepared fluorinated graphene nanoribbons have very good superhydrophobic properties and chemical stability, and thus can be applied to the anti-icing and other fields, having a very good application prospect.

  • Patent number: 10343908
    Abstract: Described herein are processes and apparatus for the large-scale synthesis of boron nitride nanotubes (BNNTs) by induction-coupled plasma (ICP). A boron-containing feedstock may be heated by ICP in the presence of nitrogen gas at an elevated pressure, to form vaporized boron. The vaporized boron may be cooled to form boron droplets, such as nanodroplets. Cooling may take place using a condenser, for example. BNNTs may then form downstream and can be harvested.

  • Patent number: 10156027
    Abstract: An equipment of manufacturing a bundle of electrospun yarn has a vortex containing device and a bundles collecting device. The vortex containing device has a feeding end, an exporting end and a vortex generator. The vortex generator is mounted in and communicates with the vortex containing device to form a fluid vortex in the vortex containing device to provide a guiding force. The guiding force draws an electrospun fiber into the feeding end of the vortex containing device. The electrospun fiber is wound to form a bundle of electrospun yarn by the fluid vortex. The bundles collecting device is rotated to collect the bundle of electrospun yarn.
