Abstract: The present application discloses a display module and a display device. The display module includes a light grating assembly. The light grating assembly includes alternately arranged first regions and second regions, and liquid crystal molecules and dye molecules distributed in the first regions and the second regions. Arrangement of the liquid crystal molecules and the dye molecules are controlled to make the first regions light-transmissive and the second regions light-transmissive under a first mode and not light-transmissive under a second mode to form alternately light and dark stripes under the second mode.

Abstract: A display device and a dimming device are provided. A dimming layer is located between a first polarizer and a second polarizer whose transmission axes are parallel to each other. When the display device is in a first display mode, long axes of the liquid crystal molecules distributed in the first polymer network are arranged along the second direction, and long axis of the liquid crystal molecules distributed in the second polymer network are arranged along the third direction. The third direction and the second direction respectively point to opposite sides of a normal line of the first polarizer.

Abstract: Ultrathin plasmene nanosheets are demonstrated as a new class of flexible surface enhanced Raman scattering (SERS) substrate capable of conformal attachment and sensitive and reproducible detection of chemicals on topologically complex surfaces. Engineering building block morphologies allows for fine-tuning of the SERS performance. In a preferred application the plasmene nanosheets are demonstrated as the next generation plasmonic and/or SERS coded labels, such as for example, anti-counterfeit security label for banknotes. Engineering the morphologies of plasmene-constituent nanoparticles and varying of SERS molecular labels offer virtually unlimited coding capacities.

Abstract: Apparatus and methods for forming self-assembly arrays of substances, such as nanoparticles, on a substrate are disclosed. The apparatus may include a substrate supporting a liquid composition including the substance and a solvent, and a removable micro-mold placed over the substrate and the liquid composition. To form the self assembly arrays of the substance, the solvent may be evaporated through at least one evaporation channel formed between the micro-mold and the substrate. The evaporation channel may be adjustable by subjecting the micro-mold to a positive pressure.

Abstract: A self-assembly nanodevice formed through nucleic acid engineering is disclosed. The nanodevice may include an array of nanoparticles. The nanodevice may further include a substrate that supports the array of nanoparticles. Each of the nanoparticles may be coordinated with a plurality of nucleic acids that are substantially free of Watson-Crick base-paring with nucleic acids coordinated with other nanoparticles. Methods of forming the nanodevice, as well as the microscopic organization of the nanoparticles are also disclosed. By manipulating the nucleic acids as capping ligands, the inter-particle distance may be extended to a greater range than nanotechnology based on alkyl ligands or nucleic acids base-pairing.
