Microdiffraction is capable of revealing the local structure within an area of the specimen consisting of only a few, or a few tens of, unit cells. However, the extent to which the diffraction pattern intensities can show the local structure depends strongly on the coherence of the illumination. If the coherence width of the illumination is smaller than the(More)
Bioinspired discontinuous nanolaminate design becomes an efficient way to mitigate the strength-ductility tradeoff in brittle materials via arresting the crack at the interface followed by controllable interface failure. The analytical solution and numerical simulation based on the nonlinear shear-lag model indicates that propagation of the interface(More)
Electron-beam-induced deposition (EBID) of carbon on the surface of carbon nanotubes was well controlled by passing different electrical currents through the nanotubes. The control is due to Joule heating and the temperature of the carbon nanotubes was estimated. The deposition rate was found to increase and then decrease with the temperature and was(More)
