“…At low frequencies we can observe electrohydrodynamic (EHD) convection in our device due to the finite resistivity of the nematic liquid crystal, 15,38 and it is important to distinguish EHD effects from those that are the subject of this paper. In our device EHD convection produces periodic circulating flow of the nematic liquid crystal in the y-direction, perpendicular to the electrode stripes.…”

“…The open circles indicate the minimum A.C. voltage for the onset of the EHD instability at different frequencies, which exhibits the sharp frequency dependency typical of the phenomenon. 15,38 Supplementary movie M1 (ESI †) demonstrates the effect of this flow on a single polymer microsphere of diameter 5.0 AE 0.1 mm. This micro particle sits within the nematic fluid in a region of the device that is far from any domain walls.…”

“…In the last decades, pattern-forming instabilities induced by electric fields in nematic liquid crystals (nematics) have been intensely studied both in theory and experiments; for a recent review see Ref. [1]. Nematics are anisotropic liquids without translational, but with long-range orientational order of their elongated molecules.…”

“…По этой причине, например, флексоэффек-том обычно пренебрегают в теоретическом анализе электроконвекции в НЖК, хотя его роль в разви-тии этой неустойчивости, как показано в послед-нее время, весьма существенна [13][14][15]. Кроме того, сравнительно недавно флексоэффект привлек вни-мание многих исследователей из-за его возможно-го использования в технологии изготовления быст-рых ЖК дисплеев [16].…”
