  • Patent number: 10982381
    Abstract: A welding process may be configured to convert a substrate into a welded substrate by applying a process solvent to the substrate, wherein the process solvent interrupts one or more intermolecular force between one or more component in the substrate. The substrate may be configured as a natural fiber, such as cellulose, hemicelluloses, and silk. The process solvent may be configured as an ionic-liquid based solvent and the welded substrate may be a congealed network after the process solvent has been adequately swollen and/or mobilized the substrate. A welding process may be configured such that individual fibers of a substrate are not fully dissolved such that material in the fiber core may be left in the native state by controlling process variables. The welding process fibers may have a tenacity 10% or 20% greater or a diameter 25% less than that of a cellulosic-based yarn substrate.

  • Patent number: 10919280
    Abstract: Precision and chip contamination-free placement of two-dimensional (2D) material and van der Waals (VDW) layered materials accelerates both the study of fundamental properties and novel device functionality. The system transfers 2D materials utilizing a combination of a narrow transfer-stamper and viscoelastic and optically transparent film. Precise placement of individual 2D materials results in vanishing cross-contamination to the substrate. The 2D printer results in an aerial cross-contamination improvement of two to three orders of magnitude relative to state-of-the-art transfer methods from a source of average area sub um{circumflex over (?)}2. The transfer-stamper does not physically harm any micro/nanostructures preexisting on the target substrates receiving the 2D material such as, nanoelectronics, waveguides or micro-ring resonators.

  • Patent number: 10903614
    Abstract: The invention relates to a method for sealing a contact point region comprising at least one contact point at an electrical line connection, wherein the line connection comprises at least one electrical line and at least one conductive element electrically connected thereto. The method starts by arranging a shrink tube on the outer circumference of the contact point region, in a first region extending over the contact point region on both sides in the longitudinal direction. This is followed by heating the shrink tube to shrinking temperature. During the heating of the shrink tube, an inductive heating of the electrical conductor is additionally performed, at least in the contact point region, and so hotmelt adhesive arranged inside the shrink tube and/or on the outer circumference of the contact point region is heated to its melting temperature. The invention also relates to a device for sealing a contact point region and to a sealing at such a region.
