Abstract:
A method for producing nano-scale particles and tubes, comprising the steps of:a) providing an ambient gas environment in a vacuum chamber;b) providing a first electrode and a second electrode in the chamber wherein at least one of the electrodes has an interior region comprising one or more conduits wherein each conduit connects a fluid source located outside the chamber to a coolant core inside the electrode, the coolant core having a drain through an exit conduit to the exterior of the chamber;c) moving material through a conduit in the first electrode;d) cooling the at least one electrode by circulating coolant through the cooling core; ande) applying a voltage between the first electrode and the second electrode, sufficient to generate an arc in an arc region, to form the nano-scale particles or tubes from the material.
