Abstract: A differential chaos shift keying (DCSK) communication method based on three-dimensional constellation is provided. Target information bit is mapped to a three-dimensional constellation symbol. An initial chaotic signal generated by a chaotic generator is processed by cyclic shift to generate a chaotic signal group including the initial chaotic signal, a first shifted chaotic signal and a second shifted chaotic signal. Information modulation is performed based on the three-dimensional constellation symbol and the chaotic signal group to obtain an information-bearing signal. A transmission signal is generated based on the information-bearing signal and the initial chaotic signal, and sent to a receiver to generate a received signal, which is subjected to information recovery analysis in the receiver to obtain an estimated information bit. A DCSK communication device based on three-dimensional constellation is also provided.

Abstract: Polyurethane-based and epoxy-based coating compositions are described that provide coatings and adhesives that are clear, amphiphobic and durable. Both water and hexadecane readily slide off these surfaces without leaving a residue. Coatings with thicknesses ranging from about 10 nm to about 10 ?m exhibited excellent transmittance properties. Such films exhibited durability against abrasion, ink-resistance, anti-graffiti, anti-fingerprint, and strong adhesion to glass surfaces. The coatings are applicable to electronic devices, fabrics, glass, etc. to prepare optically clear, stain-resistant, and smudge-resistant surfaces.

Abstract: A composite material is described that is an effective filter to separate oil from an oil and water emulsion or other mixtures of oil and water. The composite material has a permeable substrate, such as fabric, that is coated with a selectively-permeable coating. The composite material allows only oil to pass through, while water is prevented from passing through. The composite material has two main components, a hydrophobic component and an emulsion-destabilizing component.
