Engineers build chemically driven wheels that ‘morph’ into gears to perform mechanical work

Animation from simulation demonstrating spatio-temporal control of rotors via a cascade reaction. GOx-coated rotor (magenta) lies on the left side of the chamber, while CAT-coated rotor (green) lies on the right side. Background color map indicates spatial distribution of H2O2 in the solution at y = 3mm for side views and at z = 0.4 […]
