This seminar will discuss the phenomena of Teslaphoresis wherein polarizable matter undergoes directed self-assembly at a distance due to the influence of strong radiofrequency force fields transmitted by a Tesla coil. We found that single-walled carbon nanotubes placed within the Teslaphoretic force field polarize, align and rapidly (< 5 s) self-assemble from individual nanotubes (1 nm dia., 500 nm long) into macroscale nanotube wires (1 mm dia., 15 cm long). These long nanotube wires grow at great distances (> 30 cm) from the transmitter and can be used to harvest energy from the Teslaphoretic field in order to remotely power LED circuits. Furthermore, individualized carbon nanotubes in aqueous suspensions self-organize into large-scale, parallel arrays of nanotube wires with high fidelity alignment to the direction of the Teslaphoretic force field. Finally, several potential applications using Teslaphoresis will be discussed including the scalable manufacturing of nanotube fibers, field effect transistors and its role in the emerging field of bioelectronics.
