Graphical Abstract
  • colleagues have reported the rapid and reversible microactuation of liquid crystals based on the surface catalysis of H₂ and O₂ at room temperature on a late transition metal alloy film (Figure 7) [242]. The reaction of gaseous hydrogen and oxygen, catalyzed by a Pd/Au surface, is employed to rapidly and
  • reversibly alter the orientation of liquid crystals at room temperature. The dissociative adsorption of hydrogen on the palladium/gold film results in the reduction of pre-adsorbed oxygen and the generation of adsorbed hydrogen. This process causes the nitrile-containing liquid crystal to undergo a change in
  • alignment, from vertical to planar. Subsequently, exposure to oxygen oxidizes the adsorbed hydrogen, reforming the adsorbed oxygen on the Pd/Au surface and restoring the liquid crystal to its initial alignment. The motion of the liquid crystal can be controlled by exposure to gas mixtures of H2 and O2 with
