Application

Nickel can be used as a catalyst in:
  • Various reactions such as hydrogenation, oxidative addition, C−H activation, oxidative cyclization, cross-coupling reaction.
  • Selective hydrogenolysis of the aromatic ethers.
  • Steam reforming process to produce hydrogen and synthesis gas.
  • Benzaldehyde hydrogenation.
  • Methanation of CO2.

Selective hydrogenolysis of the aromatic carbon-oxygen (C-O) bonds in aryl ethers is an unsolved synthetic problem important for the generation of fuels and chemical feedstocks from biomass and for the liquefaction of coal. Currently, the hydrogenolysis of aromatic C-O bonds...

The prefrontal cortex receives multiple inputs from the hippocampal complex, which are thought to drive memory-guided behavior. Moreover, dysfunctions of both regions have been repeatedly associated with several psychiatric disorders. Therefore, understanding the interconnections and modulatory interactions between these regions...
