Abstract: Disclosed embodiments provide a method and apparatus for continuous production of micro/nanoscale particles using roll-to-roll manufacturing in combination with electroplating. The roll-to-roll process can move a mechanically flexible reel stock material along rotating elements designed to position the material for various additive, subtractive, and modification processes. In accordance with at least one embodiment, processes applied at various stations may include sputtering, electroplating, and/or etching.

Abstract: A magnetic field generator includes a power source and a segmented or un-segmented coil connected to the power source to generate a time-varying magnetic field. Energy is applied to the coil so that the coil generates a time-varying magnetic field gradient with a magnitude of at least 1 milliTesla per meter and a rise-time of less than 1000 microseconds. The coil may be comprised of overlapping, non-overlapping or partially overlapping coil segments that may individually energized to further improve the operating characteristics of the coil to further decrease bio-effects in magnetic resonance imaging through the use of reduced pulse lengths and multi-phasic magnetic gradient pulses.
