Anisotropic superconductivity in graphite intercalation compound YbC6

We report anisotropy of the upper critical field (Bc2) of an intercalated graphite superconductor YbC6 (Tc = 6.5 K) determined from angular dependent magnetoresistance measurements. Though the perpendicular coherence length is much longer than interlayer spacing, measured angular dependences of Bc2 are well fitted by the Lawrence-Doniach model or the Tinkham model, which are known to be applica...

Hydrogen Desorption Properties of Nanocrystalline MgH2-10 wt.% ZrB2 Composite Prepared by Mechanical Alloying

Storage of hydrogen is one of the key challenges in developing hydrogen economy. Magnesium hydride (MgH2) is an attractive candidate for solid-state hydrogen storage for on-board applications. In this study, 10 wt.% ZrB2 was co-milled with magnesium hydride at different milling times to produce nanocrystalline composite powder. The effect of milling time and additive on the hydrogen desorption...

Preparation and characterization of a tetrabutylammonium graphite intercalation compound.

The intercalation of tetrabutylammonium (TBA) cations into graphite by cation exchange from a sodium-ethylenediamine graphite intercalation compound yields a single-phase first-stage product, C(44)TBA, with a gallery expansion of 0.47 nm. The gallery dimension requires an anisotropic "flattened" cation conformation.

Ternary Intercalation Compound of Graphite with Aluminum Fluoride and Fluorine

A ternary intercalation compound of graphite with AIF3 and F2, CXF(A1F3)J/ was prepared under fluorine atmosphere at temperatures of 20-400 °C. The typical 1st stage compound has a composition of C6F(AlF3)o,i5 with a repeat distance of 940 pm. Rapid progress in the reaction led of the formation of graphite fluoride, (C2F),,. ESCA spectra indicate that the chemical bond between host graphite and...
