  • Patent number: 10236181
    Abstract: A manufacturing system and a method for forming a clean interface between a functional layer and a 2D layered semiconductor are provided herein. In the steps of the method, the substrate equipped with the 2D layered semiconductor is exposed to a reaction gas, and a stimulus is applied to the reaction gas to generate active particles having higher selectivity toward contaminants on the exposed surface of the 2D layered semiconductor so that the contaminants can be decomposed and removed. Additionally, the contaminants can be removed without damage to the 2D layered semiconductor. A functional layer is in-situ deposited to be in contact with the 2D layered semiconductor. Without the contaminants, a clean interface between the functional layer and the 2D layered semiconductor can be obtained and the 2D layered semiconductor can exhibit better electrical properties.

  • Patent number: 10179314
    Abstract: The invention, belonging to the field of membrane technology, presents a method for the high-throughput preparation of carbon nanotube hollow fiber membranes. This method contains three major steps. Firstly, the pristine carbon nanotubes (CNTs) are added into a mixture of concentrated nitric acid and sulfuric acid, which is then heated at 40˜80° C. for 0.5˜6 hours. Secondly, the surface-functionalized CNTs and polyvinyl butyral (PVB) are dispersed and dissolved, respectively, in organic solvents at a mass ratio of 1:0.2˜1:4˜8 to form homogeneous spinning solution, which is squeezed into water as shell liquid with water as core liquid at a flow rate ratios of 0.5˜5:1 through a spinneret to form CNT/PVB hollow fibers. Finally, the dry fibers are calcinated at 600˜1000 ° C. for 1˜4 hours in absence of oxygen to produce free-standing CNT hollow fiber membranes. The method involved in this invention is simple and highly efficient without needing any templates, expensive apparatuses and chemicals.

  • Patent number: 9870839
    Abstract: IR emission devices comprising an array of polaritonic IR emitters arranged on a substrate, where the emitters are coupled to a heater configured to provide heat to one or more of the emitters. When the emitters are heated, they produce an infrared emission that can be polarized and whose spectral emission range, emission wavelength, and/or emission linewidth can be tuned by the polaritonic material used to form the elements of the array and/or by the size and/or shape of the emitters. The IR emission can be modulated by the induction of a strain into a ferroelectric, a change in the crystalline phase of a phase change material and/or by quickly applying and dissipating heat applied to the polaritonic nanostructure. The IR emission can be designed to be hidden in the thermal background so that it can be observed only under the appropriate filtering and/or demodulation conditions.
