	No. 9 - May 2006 APPLICATION OF THE MONTH: Nanotube based light-sources Carbon nanotubes can act as light sources, being capable of direct photon emission. Nanotube bundles can effectively work as filaments in incandescent light bulbs. In addition, at the nanoscale, individual nanotubes can exhibit opto-electronic polarized emission or will even feature field-emission induced luminescence... READ MORE... ANATOMY OF A PATENTING AREA: Functionalization of carbon nanotubes By far, the group at Rice University proved to be the most active in the patenting area of carbon nanotubes functionalization. Although this might seem only a step toward other application or processing areas, mastering nanotubes functionalization may provide an extremely strong tool... READ MORE... FEATURED EQUIPMENT: Imaging of Carbon Nanotubes Atomic Force Microscopy (AFM) is often used to reveal information on the size and the topographical surface structures of carbon nanotubes. However, acquiring additional chemical information or differentiating between single-wall (SWCNT) and multi-wall (MWCNT) nanotubes is still a difficult task when using AFM. To overcome this limitation, Raman spectroscopy can be used for a more detailed characterization of the chemical constitution of the nanotubes. Raman spectra directly reflect the chemical composition and the molecular structure allowing, for example, to clearly distinguish the nanotube-types upon their individual Raman spectra. In order to investigate nanotubes, a high resolution Raman microscopy system must be used... READ MORE... RESEARCH PAPERS IN APRIL (146) Production Zhang, L., Tan, Y., Resasco, D.E.
