N2 - A nematic-to-isotropic transition was obsd. in suspensions of C nanotubes (CNTs) and a cyanobiphenyl-based liq. crystal (LC) confined within an In Sn oxide glass sandwich cell. Upon the application of elec. field, CNTs rotate out of plane short-circuiting the electrodes and producing a current flow through the CNTs. The resulting Joule heating leads to a local increase in temp. of the LC-CNT medium. Hence, starting from a metastable nematic phase, a complete transition to the isotropic phase is obsd. On removal of the elec. field, the transition is reversed with the LC-CNT medium returning to the nematic phase. (c) 2008 American Institute of Physics.
