Systems and techniques for traffic splitting based on latency between cells are herein described. In various embodiments, the metal oxide or metal hydroxide nanocrystals have reactive atoms stabilized on their surfaces, species adsorbed on their surfaces, or are coated with a second metal oxide. The hinge enables each side panel and end panel to pivot down for access to the baked goods and pivot back up for cooking. The power supply is connectable to an external power source to provide voltage to at least the load. The second recess is located at a position different from the first recess. The RFID antenna includes an electric conductor and a conductor that radiate electromagnetic fields isotropically.
