    Abstract: The present invention is related to a process for generation of hydrogen and syngas based on biomimetic carbonation and photocatalysis. A path breaking way has been developed for generation of solar fuels in specific hydrogen by coupling biomimetic carbonation with photocatalysis. Efforts are being made worldwide to mimic the reaction for fixation of anthropogenic CO2 into calcium carbonate using carbonic anhydrase (CA) as a biocatalyst. CA is being employed to accelerate the rate of hydration of CO2 to form carbonate ions and proton. Presently carbonate is being precipitated from aqueous solution as calcium carbonate given a suitable saturation of calcium and carbonate ions by addition of appropriate buffer. A major breakthrough in the area of generation of solar fuels like hydrogen has been achieved by coupling biomimetic carbonation with photocatalysis. This approach may prove to be a revolutionary technical advancement required for hydrogen economy demanding carbon neutral hydrogen production. Also the production of hydrogen in addition to carbonates as end products during biomimetic carbonation may make the process commercially viable to be adopted by industries emitting carbon dioxide. The carbonate rich stream has been photocatalytically reduced to formaldehyde. This breakthrough thus opens new horizons in the area of carbon sequestration by virtue of the fact that end product of carbon sequestration is not only environmentally benign product of calcite but it would lead to the generation of clean energy including hydrogen, methane and methanol. Maximum hydrogen evolution has been observed up to 101.14 μmoles/mg of,free CA, 156.8 μmoles/mg of immobilised CA and 101.14 μmoles/mg of CA 6684.5 μmoles/mg of stabilised CA using TiO2/Zn/Pt as photocatalyst. The problem of using Zn as a metal donor has been overcome by illuminating the system. Hydrogen evolution to the tune of 84 μmoles/mg of CA has been observed for system with Zn as metal donor in the presence of Pt as co-catalyst with illumination.

    Abstract: A network device provides a selector list that includes indices of child nexthops associated with the network device, where each of the child nexthops is associated with a corresponding child link provided in an aggregated bundle of child links. The network device also receives an indication of a failure of a child link in the aggregated bundle of child links, and removes, from the selector list, an index of a child nexthop associated with the failed child link. The network device further receives probabilities associated with the child links of the aggregated bundle of child links. Each of the probabilities indicates a probability of a packet exiting the network device on a child link. The network device also creates a distribution table based on the probabilities associated with the child links, and rearranges values provided in the distribution table.
