Abstract: An electrolyte is disclosed, for example for use in a capacitor or in a battery. An electrolyte comprises a polysaccharide matrix; and carbon nanotubes embedded within the polysaccharide matrix. Further, apparatus comprising the electrolyte is disclosed. A method of manufacturing an electrolyte is disclosed. According to the method a polysaccharide solution is provided; carbon nanotubes are suspended within the polysaccharide solution; and the polysaccharide solution is dehydrated to obtain a gel.

Abstract: A smart sticker for determining the current state of raw meat for safe human consumption is provided. The smart sticker indicates the quality or decomposition of the meat by changing color. The smart sticker employs a cupric nitrate solution mixed with a polymeric silicon substrate that forms a complex with the valence electrons on the nitrogen atom of an amino acid residue. After this interaction occurs, the smart sticker changes color from, for example, light blue to purple.

Abstract: A “smart sticker” employing nanotechnology for determining the current state of raw meat for safe human consumption is provided. The sticker indicates the quality to the consumer by providing a color changing indicator on the sticker. The sticker employs carbon nanoparticles containing iron, which are placed on an underside portion of the sticker in contact with the raw meat. The nanoparticles serve as “bait” for the harmful bacteria. When pathogenic bacteria sense the presence of iron, it produces certain molecules to sequester the iron. Those molecules move to the area where the iron is present in the sticker, which can then determine the amount of pathogenic bacteria present in the meat by way of a chemical reaction with a particular ink containing a novel additive, which reacts with the molecules secreted by the pathogens. Once this interaction occurs, the ink changes color from, for example, blue to yellow.
