Embedded nanotube array sensor and method of making a nanotube polymer composite

March 9th, 2010 A method of producing polymer/nanotube composites where the density and position of the nanotubes ( 11 ) within the composite ca be controlled. Carbon nanotubes ( 11 ) are grown from organometallic micropatterns. These periodic nanotube arrays are then incorporated into a polymer matrix ( 7 ) by deposing a curable polymer film on the as-grown tubes. This controlled method of producing free-standing nanotube/polymer composite films may be used to form nanosensor ( 3 ) which provide information regarding a physical condition of a material ( 20 ), such as an airplane chassis or wing, in contact with the nanosensor ( 3 ).

Precision shape modification of nanodevices with a low-energy electron beam

March 9th, 2010 Methods of shape modifying a nanodevice by contacting it with a low-energy focused electron beam are disclosed here. In one embodiment, a nanodevice may be permanently reformed to a different geometry through an application of a deforming force and a low-energy focused electron beam. With the addition of an assist gas, material may be removed from the nanodevice through application of the low-energy focused electron beam. The independent methods of shape modification and material removal may be used either individually or simultaneously. Precision cuts with accuracies as high as 10 nm may be achieved through the use of precision low-energy Scanning Electron Microscope scan beams. These methods may be used in an automated system to produce nanodevices of very precise dimensions. These methods may be used to produce nanodevices of carbon-based, silicon-based, or other compositions by varying the assist gas.
