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.

Abstract: The present invention provides a thermally-decomposable consolidated polymer particle encapsulated-electrode for a lithium-ion battery. The electrode includes polymer particles including at least one connection unit and at least one crosslinker in an amount of approximately 40% to 98% by weight and at least one binder material in an amount of approximately from 2% to 60% by weight. The consolidated crosslinked polymer particle coating results in a porous structure encapsulating the electrode. The pressure resistance of the consolidated crosslinked polymer particle coating ranges approximately from 0.5 to 8 MPa and the consolidated crosslinked polymer particle coating is decomposed to release a non-flammable gas and phosphorous-containing molecules so as to prevent thermal runaway at a temperature approximately from 300° C. to 500° C.
