  1. Fabrication of Paper-Templated Structures of Noble Metals

    A method for fabricating structures composed of noble metals and having physical morphology that resembles paper, thread, or fabric is described. A template (i.e., paper or cotton fabric) is loaded with solutions of metal precursors, and then the cellulosic component is burned off in a furnace. The resulting largely metallic structures are fibrous, liquid and gas permeable, and electrically conductive.

  2. 3D-Printed Autonomous Sensory Composites

    A method for 3D-printing autonomous sensory composites requiring no external processing is presented. The composite operates at 1.5 V, locally performs active signal transduction with embedded electrical gain, and responds to stimuli, reversibly transducing mechanical strain into a transparency change. Digital assembly of spatially tailored solids and thin films, with encapsulated liquids, provides a route for realizing complex autonomous systems.

  3. Solvent-Based Soft-Patterning of Graphene Lateral Heterostructures for Broadband High-Speed Metal–Semiconductor–Metal Photodetectors

    A solvent-based “soft-patterning” strategy to fabricate graphene-fluorinated graphene (FG) lateral heterostructures with resolution down to 50 nm is demonstrated. The fabricated lateral graphene-FG heterostructures are employed to demonstrate a high speed metal–semiconductor–metal photodetector (<10 ns response time), with a broadband response from deep-UV (200 nm) to near-infrared (1100 nm) range.

  4. A Foolproof Method to Fabricate Integrated Electrodes with 3D Conductive Networks: A Case Study of MnOx@C-Cu as Li-Ion Battery Anode

    A scaled-up foolproof method is developed to fabricate integrated electrodes with 3D conductive networks with the help of polyvinylpyrrolidone. It is low cost and environmentally friendly. The electrodes prepared in this method show superior electrochemical performances when evaluated as Li-ion battery anodes. This method can be extended to the construction of other functional integrated electrodes, with the potential for extensive applications.

  5. Shrinkage Control of Photoresist for Large-Area Fabrication of Sub-30 nm Periodic Nanocolumns

    Hai Le-The, Erwin Berenschot, Roald M. Tiggelaar, Niels R. Tas, Albert van den Berg and Jan C. T. Eijkel

    An enabling technique for large-scale fabrication of highly-ordered size-tunable nanocolumn arrays without a deep-UV-laser source is successfully demonstrated. Periodic 110 nm diameter photoresist nanocolumns patternd by displacement Talbot lithography can be directly transferred to 110 nm bottom anti-reflection layer coating (BARC) nanocolumns using N2 plasma etching, or shrink-etched to sub-30 nm highly vertical BARC nanocolumns using O2/N2 plasma etching.
