Abstract: Methods for constructing multi-walled carbon nanotube (MWCNT) antenna arrays, may include: variable doping of the MWCNTs, forming light pipes with layers of variable dielectric glass, forming geometric diodes on full-wave rectified devices that propagate both electrons and holes, using clear conductive ground plans to form windows that can control a building's internal temperature, and generating multiple lithographic patterns with a single mask.

Abstract: The food carrier comprises a plurality of stacked, interchangeable rigid food tray assemblies, at least one of the tray assemblies having a plurality of compartments formed therein. A strap secures the stacked food tray assemblies to each other, the strap comprises a handle for carrying the food carrier. A thermally insulative cover is provided for the outside of the food tray assemblies for stabilizing the temperature of any food contained therein.
