Abstract: Carbon nanostructures such as multiwalled carbon nanotubes are formed from electrolyzed coal char. The electrolyzed coal char is formed by forming a slurry of coal particles, metal catalyst and water and subjecting this to electrolysis, which generates carbon dioxide and hydrogen. This forms a coating on the particles which includes metal catalysts. These particles can be used as is for formation of multi-walled carbon nanotubes using a pyrolysis method or other method without the addition of any catalyst. The gelatinous coating can be separated from the char and used as a fuel or as a carbon source to form carbon nanostructures.

Abstract: The present invention provides methods for detecting and correcting transmission errors in inter-router links of Network-on-Chip (NoC) architectures. A NoC has repeaters along its bus lines. The output of a main repeater is compared and multiplexed with the output of a shadow repeater. If these outputs are the same the multiplexer outputs the output of the main repeater, otherwise an error is detected and the multiplexer outputs the output of the shadow repeater.
