Abstract: A method of making a reference electrode assembly for an electrochemical cell according to various aspects of the present disclosure includes providing a subassembly including a separator layer and a current collector layer coupled to the separator layer. The method further includes providing an electrode ink including an electroactive material, a binder, and a solvent. The method further includes creating a reference electrode precursor by applying an electroactive precursor layer to the current collector layer. The electroactive precursor layer covers greater than or equal to about 90% of a superficial surface area of a surface of the current collector layer. The electroactive precursor layer includes the electrode ink. The method further includes creating the reference electrode assembly by drying the electroactive precursor layer to remove at least a portion of the solvent, thereby forming an electroactive layer. The electroactive layer is solid and porous.

Abstract: A system includes a display. The display includes an array of LEDs covered by a transparent material. The array of LEDs includes a plurality of first, second, third, and fourth LEDs respectively configured to emit red, green, blue, and violet light. The red, green, and blue light from the first, second, and third LEDs is visible to human eye. Violet light from the fourth LEDs is invisible to human eye. The system includes a photocatalytic coating disposed on the transparent material. The photocatalytic coating includes a photo-catalyst responsive to ultraviolet radiation present in sunlight and to the violet light emitted by the fourth LEDs in the array of LEDs. The system includes a controller configured to selectively turn on the fourth LEDs to activate the photo-catalyst in the photocatalytic coating disposed on the transparent material.
