  • Publication number: 20230303901
    Abstract: An immersion cooling system includes a fluid-retaining container having space for accommodating an electronic device. A heat transfer fluid is in contact with the electronic device. A heat exchanger contacts and condenses vapor from vaporization of the heat transfer fluid. The heat transfer fluid has a thermal conductivity higher than 0.08 W m?1K?1, a dielectric constant (Dk) 20-40 GHz less than 3.0, and a heat of vaporization higher than 150 kJ kg?1, with fire retarding features, compatibility with plastics, metals, rubbers and includes a partially fluorinated compound. The improved immersion cooling system includes fluids with increased thermal conductivity and heat of vaporization while reducing fluid density and maintaining the advantages of the fluid being non-flammable, having high electrical stability and a low dielectric constant.

  • Patent number: 11435620
    Abstract: A quantum dot-based color display includes a backlight unit with a light source and light source distribution layer and a photo down-conversion light emissive layer. The photo down-conversion layer has populations of light-emitting Group II-VI core-shell structure quantum dots, the core having an excess amount of a Group II component in a ratio to a Group VI component of approximately 6:1 or greater. The quantum dots include an organic fraction of approximately 20 weight percent to approximately 45 weight percent, the organic fraction including ligands bound to quantum dot surfaces in an as-deposited state and including one or more long-chain fatty acids. Non-barrier polymer films are positioned on either side of the photo down conversion light emissive layer which exhibits photo stability at a light intensity of at least 4000 W/m2. A display panel cooperates with the back light unit to form the display.

  • Patent number: 11365347
    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.
