An x-ray study of the structure of K1-xRbxCy
… graphite hexagonal planes. We report extensive x-ray scattering investigations of the structural aspects of these compounds. In stage 1 K1-xRbxC8, we find that the interlayer separation exhibits a slight deviation from linearity, independent of the graphite material used (pyrolytic graphite or …

X-ray study of the ordering phase transition at the Cu3Au (111) surface
… (111) surface of Cu3Au by glancing incidence x-ray scattering. The experiment was designed to approach the general question of surface behavior near a bulk first order phase transition. We have studied three aspects of the phase transition: the surface order parameters, the order parameter …

X-ray study of the stacking fault density near the hardness maximum of the Au-Ag-Pd system
The annealed hardness of certain dental alloys has been measured and found to be in relatively good agreement with the existing hardness map. In addition, lattice parameters, stacking fault densities, and spacing change fractions have been determined for those alloys. The lattice parameters were …

An X-ray study of charge-density-wave pinning and a measurement of the thermal conductivity in blue bronze
… npin were determined by high-resolution X-ray diffraction. The main results are that the phase coherence volume contains many pinning sites, and that the coherence length along two of the three directions measured decreases roughly as n;i~· 4 . A functional form for the phase coherence …

ALKYLATION AND OXIDATIONS OF SYMMETRICAL DIMETHYLENEBIPHENYL AND RELATED DIANIONS (CYCLOPHANE, BIPHENYLOPHANE, NMR, CONFORMATION).
… route to n.0 - and n.0.n.0 cyclophanes. An X-ray study on 14.0 paracyclophane showed it to have a conformation different from that observed in solution by NMR; MM2 calculations were used in determining what the solution conformation is likely to be. Oxidation of the dianions produced the …
