(a) Power generation fueled by DPA peptide-MOF motors with time. (b) Expanded power generation patterns around 10s of rotation. (c) Expanded power generation patterns around 770s of rotation. (d) Correlation between induced voltage and velocity of rotor powered by DPA-MOF(HKUST-1) motors. (e) Power generation with recycled DPA peptide-MOF motors. As one cycle of generation is completed, MOFs are recovered and re-incorporate DPA peptides in the same way that the peptide is amounted originally after dried. The electric power can be repeatedly generated up to five cycles without the loss of generation. The power generation plot superimposes 1st cycle (green) and 5th cycle (pink) of DPA peptide-MOF motors to display the recovery after refilling peptides in the MOF. The power generation of each cycle is measured five times and this plot is averaged.
