"motion imparts chiral twist on orderly carbon nanotube (CNT) resulting in tornado and twisted-and-stacked thin films... control elliptic level and range of polarized light enabling tunable chirality... combine CNT filtration and shaking to tune characteristics of wafer-scale films... 2nd method of achieving chirality: stacking highly aligned CNT films at angle by controlling number of layers and twisting angles... new record for ellipticity in deep UV range... imaging, sensors, communications, quantum computers, lasers"
