This engineering study examines multi-wall carbon nanotubes suspended in water exposed to AC electric fields generated by 3D electrodes. It reports field-induced polarization leading to nanotube alignment and long-range, electrically conducting assemblies spanning the electrode gap, with assembly length controlled by…

This Physical Review Letters paper reports a method to reverse electric polarization in multiferroic TbMnO3 using a rotating magnetic-field direction, without applying an electric field or heat. The authors state that the direction of magnetic-field-induced polarization along the a axis is retained as a memory even…

This paper reports that the electronic gap in bilayer graphene can be controlled externally via a gate bias (electric field effect). Using magnetotransport (Shubnikov-de Haas) data and a tight-binding model, the authors extract the gap as a function of electronic density. They report tuning the gap from zero to…

This in vitro study examined whether astrocyte alignment induced by an applied electric field influences neurite outgrowth. Astrocytes were pre-aligned using a physiological-strength electric field (500 mV mm(-1)), and dorsal root ganglia cells were then seeded onto them. Neurite outgrowth at 24 and 48 hours was…
