the electrolysis efficiency to produce ammonia was high, in excess of 30% when we used either wet air or wet nitrogen reactants and with nano fe 2 o 3 to provide iron as a reactive surface (). this observed >30% efficiency for the conversion of electrons, air, and water to ammonia compares with the highest values of <1% previously noted for the generation of ammonia from air or nitrogen and
bead beating, also known as bead mill or ball mill, disrupts cells by the impact of high speed spinning of fine beads on the biomass slurry. the whole disruption process could be done within minutes, and it could be applied to any kinds of microalgae without preparation [ 18, 19 ].
