Abstract: An electric cooking appliance includes a glass-ceramic substrate having a top surface for supporting cookware for heating thereon, and a bottom surface opposite the top surface. The electric cooking appliance includes a plurality of thermoresistive heating elements disposed and spaced apart on the bottom surface of the glass-ceramic substrate, with each of the plurality of thermoresistive heating elements including graphene nanoparticles embedded in a ceramic matrix for generating heat upon application of electric current to the respective thermoresistive heating element. Each thermoresistive heating element is electrically connected to a power supply such that one or more of the plurality of thermoresistive heating elements are selectively activated to receive electric current to heat localized areas of the glass-ceramic substrate.

Abstract: A method of making a liner for an appliance is provided. The method includes mixing a polymeric capping layer precursor and a pigment additive to form a color capping layer. The method further includes extruding a polymeric base resin to form a polymeric base layer at a base layer formation temperature. The method further includes laminating a barrier layer between the polymeric base layer and the color capping layer to form the liner at about the base layer formation temperature. The method also includes forming a textured pattern on an outer surface of the color capping layer. The formed liner includes a capping region, a barrier region, and a base region where the capping region includes the pigment additive. The method may additionally include shaping the liner into a final liner at a shaping temperature where the final liner is configured and/or is suitable for assembly into a refrigeration appliance.

Abstract: A hybrid structure ultraviolet dye for leak detection in an appliance includes a ceramic matrix defining pores, and fluorophores encapsulated in nanoparticles bonded to the ceramic matrix within the pores. Upon excitation, the fluorophores release energy and emit fluorescent light to be detected under an ultraviolet lamp. The hybrid structure ultraviolet dye can be included in the refrigerant of a sealed system such that upon refrigerant, the hybrid structure ultraviolet dye, or both exit the sealed system at a leak onto external surfaces of the components, the color emitted by the fluorophores can be detected via application of a UV light.
