Musculoskeletal Diseases 2017-2020s intercalation compounds exhibit phonon frequencies as high as 200 meV. Most existing neutron sources allow the investigation of phonon frequencies only up to about 100 meV. It is therefore the lower part of the phonon dispersion of graphite intercalation compounds which is discussed here. Compleme

Neutron scattering is of course the most powerful technique for examining the vibrational excitations of solids since one can examine the phonon dispersion curves throughout the wave-vector range of the Brillouin zone (BZ). In contrast, first-order infrared absorption/reflection spectros

Often, the intercalation process proceeds via a well-defined intercalation front which can be observed readily, e g, from a change in the sample thickness

New Mechanisms for the Mobilization of the Platinum-Group Elements in the Supergene Zonents in the supergene environment. Calculations indicate that this is easily accomplished for Pt and Pd. Applications to secondary enrichment, nugget formation and potential geochemical exploration methods are indicated.
