Get PriceThis report describes aspects of our previous studies of the mechanochemical synthesis of charge transfer complexes of the electron donor tetrathiafulvalene, which are relevant to the use of laboratory X-ray powder diffraction for ex situ monitoring of mechanochemical reactions toward investigating their mechanisms. In particular, the reaction of tetrathiafulvalene and chloranil
Get PriceElectron energy loss spectroscopy (EELS) is the analysis of the distribution of electron energies emergent from a thin-foil specimen. The electrons in the primary beam are decelerated and lose energy as they pass through the thin sample by several mechanisms, but it is the loss due to ionization of inner shell electrons in the sample that provides the most useful information.
