This is an abstract for a presentation given at the
10th Foresight Conference on Molecular Nanotechnology


We have built, and use, nanomanipulation/testing stages that operate inside a scanning electron microscope to measure the tensile stiffness and strength of carbon nanotubes (CNTs), to uncover a unique "shell sliding" (nanobearing) mechanics in multiwalled CNTs, and to excite and drive the mechanical resonances of both CNTs and various types of nanowires (NWs), such as pure boron nanowires and SiO2 nanowires. These various topics will be presented in this talk, as well as some of our synthesis efforts (aimed at synthesizing novel B and BN NTs and NWs). Target areas for applications are in sensors, nanoelectronics, high stiffness/strength cabling and composites, and in biomedical as nanoelectrodes, nanopipettes, as a structural component in biocompatible composites. Support is gratefully appreciated from: NSF, ONR, NASA, SRC, and Zyvex.
