    Neutron Scattering Study of Layered Silicates Pillared with Alkylandnonium Ions

    Incoherent, inelastic neutron scattering has been used to study the vibrational spectra of tetramethylammonium montmorillonite and trimethylammonium vermiculite in the energy range 20–140 meV. For both systems...

    Raman Spectra of Ion Intercalated Vermiculites

    The Raman spectra of ion intercalated Vermiculites have been studied. The torsional mode frequencies exhibit a shift to higher energy with increasing basal spacing d. Using a van der Waals type force model, an...

    Structural and Dynamical Properties of Intercalated Layered Silicates

    Structural and dynamical properties of intercalated solids in general [1], and layered silicates of the type AxB1−x -Vermiculite in particular, are of both fundamental and practical interest. In these systems, tw...

    A Field Emission Stem Study of the Br Distribution in Brominated Graphite Fibers

    Brominated pitch based graphite fibers exhibit certain novel properties and potential applications [1,2]. For example, it has been observed that an 18 fold reduction of their resistivities of the pitch-based g...

    Evidence for a Two-Dimensional Metal-Insulator Transition in Potassium-Ammonia Graphite

    We have studied the ammonia pressure dependence and composition dependence of the a-axis electrical resistivity of the potassium-ammonia ternary graphite intercalation compounds K(NH3)XC2 4, O < × < 4.33. Our res...

    Ternary Graphite Intercalation Compounds

    Ternary graphite intercalation compounds (T GIC’s) are materials which contain two distinct intercalant species in the host galleries. The two species may be donor ions such as potassium and rubidium [1], acce...
