General description

Surface area of the graphitized mesoporous carbon was determined to be 77 m2/g. These are highly pure graphitized, porous carbon nanoparticles. Particles have large mesopores and some microporosity. Graphite lattice structure content of approximately 10%. An agglomeration of 30 nm mesoporous nanoparticles (TEM).

Application

The cytotoxic effects of graphitized carbon mesoporous nanopowder and multiwalled carbon nanotubes (MWNTs) was compared on human airway epithelium. Mesoporous carbon was found to have no effect on the epithelium cell morphology.

Fundamental differences in methane (CH4) production between macropods (kangaroos) and ruminants have been suggested and linked to differences in the composition of the forestomach microbiome. Using six western grey kangaroos (Macropus fuliginosus) and four red kangaroos (Macropus rufus), we measured...
