Investigating sorption on iron-oxyhydroxide soil minerals by solid-state NMR spectroscopy: A (super 6)Li MAS NMR study of adsorption and absorption on goethite
Article Abstract:
Li sorption was investigated as a function of pH, the system representing an ideal model system for NMR studies. (super 6)Li resonances with large hyperfine shifts were observed above the goethite point of zero charge, providing a clear evidence for the presence of Li-O-Fe connectivities, and thus the formation of an inner sphere Li(super +) complex on the goethite surface.

(super 2)H MAS NMR studies of deuterated geothite (alpha-FeOOD)
Article Abstract:
The deuterated form of iron oxyhydroxide goethite (alpha-FeOOD), one of the major inorganic components of soil, was studied by using the (super 2)H MAS NMR spectroscopy. The feasibility of applying NMR methods to characterize the local internal and surface structures of these classes of materials is demonstrated.

Effects of KI encapsulation in single-walled carbon nanotubes by Raman and optical absorption spectroscopy
Article Abstract:
Raman spectroscopy and optical absorption are used to study the effects of KI encapsulation in narrow (HiPCO) single-walled carbon nanotubes (SWNTs). The encapsulation of inorganic compounds through the molten-phase route has provided stable effects due to maximal occupation of the nanotube inner space.
