070073: Efficient Selection of Carbon Nanotubes by Desired Properties

In the beginning powder form, carbon nanotubes (CNTs) have a wide range of physical dimensions and electrical properties at the level of individual CNTs. A number of researchers have tried various methods of selecting and manipulating (CNTs) produced in batch quantities. However, these processes do not select CNTs by specific dimensions, or sel...

050122: Pneumatic Nano-Probe Tip for Nano-Manipulation and Manufacturing

A major problem with nano-manipulation is holding the target. Due to the lack of micro force/flow feedback, the target is often destroyed during its manipulation. It would be highly desirable to have a means for picking up and releasing nano-objects without the above difficulties. Description The current invention addresses current operational ...
