Abstract: Systems & methods for sorting single-walled carbon nanotubes (SWNTs) using an iDEP-based sorting device. The device includes an inlet channel with a constriction and the inlet channel splits into multiple different channels after the constriction—the multiple channels includes a center channel and at least one side channel. A sample is introduced into the iDEP sorting device containing a plurality of SWNTs of different lengths suspended in a fluid. An electrical field is applied to the sample between a first electrode in the center channel and a second electrodes at a proximal end of the inlet channel. The applied electrical field causes longer SWNTs to move towards the side channels while the shorter SWNTs move towards the center channel. Accordingly, a first plurality of shorter SWNTs is then collected from the center channel and a second plurality of longer SWNTs is collected from the at least one side channel.

Abstract: A vibratory screening machine includes replaceable screen assemblies. Compression mechanisms are used to secure replaceable screen assemblies to the vibratory screening machine. Each compression mechanism applies a force to a replaceable screen assembly that includes both a horizontal component and a downward vertical component. Each replaceable screen assembly is typically substantially flat prior to installation on a vibratory screening machine. The force applied to a screen assembly by one or more compression mechanisms causes the screen assembly to be pushed into engagement with underlying concave support members such that the screen assembly itself assumes a concave shape with the center of the screen assembly being lower than the side edges. The vertical downward component of the force helps to secure the screen assembly to the screening machine.

Abstract: Systems and methods for separating materials and recovery of valuable copper from shredded end-of-life vehicles and appliances are disclosed. The system utilizes a pair of conveyor belts; one for de-watering and removing most of the plastic and glass particles and a second below the first for separating the copper wire bits. The second conveyor belt has a belt with a particular tooth pattern and material softness, and is set at a slight uphill incline angle. Water is delivered from the top down the slope and the belt successfully transports mostly just copper up and over a top edge to a collection bin. A cascading series of pairs of conveyors may be used to ensure nearly complete recovery of the copper. A secondary copper recovery conveyor having a field of nails or spikes may be added subsequent to the last primary conveyor for enhanced yield of copper wire.
