In situ transmission electron microscopy nanoindentation tests are used to measure the compressive fracture and mechanical properties of individual titanium oxide (TiO2) capped nanotubes. The average critical loads ranged from 3.6 to 9.6 mu N. Individual TiO2 capped nanotubes with lengths of 8-10 mu m were found to have Young's modulus values of similar to 2.2-9.4 GPa and work energy values of similar to 3.1-6.6 x 10(-13) J. The results indicate that the Young's modulus and tensile strength depend on capped nanotube length.
