In situ TEM observation of material ejection from a SWNT.

In situ study showing the dynamics of a SCC bridging two SWNTs inside a host tube. (in collaboration with Max-Planck-Institut für Chemische Physik fester Stoffe and Technische Universität Dresden) http://prb.aps.org/abstract/PRB/v81/i8/e085439

Comparison of original and simulation of a TEM image of the SWNT/SCC molecular junction using molecular models. (a) Fourier filtered TEM image, (b) Fourier filtered output of a multi-slice simulation of the imaging process, (c) ball-and-stick illustration of the underlying molecular model for the simulation, and (d) of the inner part of the model to highlight the single carbon chain.
