Abstract: A visible light activated ink that produces a color change when exposed to visible light is provided. The ink includes a visible light activated photochromic compound, one or more binders, additives including one or more surfactants, and a solvent. The visible light activated ink is substantially colorless in the as-deposited state and requires a visible light intensity of approximately 300 W/m2 or greater at a wavelength of approximately 400-700 nm to produce a color change.

Abstract: A method for preparation of perovskite quantum dot (PQD)/polymer/ceramic ternary complex includes encapsulation of bifunctional coating including ceramic and polymer. Encapsulation sequence of polymer and ceramic may be altered according to the application. In one scenario, the perovskite quantum dots may be protected with ceramic coating first and further coated with polymer to obtain the perovskite/ceramic/polymer ternary complex. In another scenario, the perovskite quantum dots may be protected with polymer coating first and followed by ceramic coating to obtain the perovskite/polymer/ceramic ternary complex. The PQD ternary complex may provide synergistic effect on improvement of stability towards heat and moisture when compared to existing technology.

Abstract: The present application provides a lithium ion battery including a thermal sensitive layer comprising polymer particles. The thermal sensitive layer may be disposed between the electrodes and the separator. When the lithium ion battery is under thermal runaway condition and the internal temperature rises to a critical temperature, the polymer particles undergo a thermal transition process (melting) to form an insulating barrier on the electrodes, which blocks lithium ion transfer between the electrodes and shuts down the internal current of the battery.
