Abstract:
There is considerable interest in the adhesion of polymers to carbon nanotubes for nanocomposite applications.(1-4) One example is multiwalled carbon nanotubes (MWCNTs) dispersed in nylon 6,6.(5) We will show that high-contrast tomographic reconstructions can be created from plasmon-loss electrons that show the three-dimensional structural complexity of the MWCNT-nylon composite at the nanoscale. Further, by recording a series of energy-loss images at successive tilts, it is possible to interrogate subvolumes to extract energy-loss spectra from the reconstructed "volume spectra".

Raman Spectroscopy Instrumentation: Overview
The monochromatic laser source, typically using visible or near-infrared radiation, generates a highly focused beam of light. This light interacts with the molecules of the sample, scattering some of the light. Liquid and gaseous samples are usually tested in ordinary glass capillaries, while solids can be analyzed as powders packed in capillaries or as potassium...
