Ceramic samples of Pb 0.99 La 0.01 (Zr 0.91 Ti0.09)O 3 were studied by dielectric and time-of-flight neutron diffraction measurements at 300 and 250 K versus pressure. Isothermal dielectric data (300/250 K) suggest structural transitions with onsets

The crystal structure of form III of the title compound, HNAB [systematic name: bis(2,4,6-trinitrophenyl)diazene], C12H4N8O12, has finally been solved as a pseudo-merohedral twin (monoclinic space group P2(1), rather than the orthorhombic space group

We have studied the reversible pressure induced structural transition (primitive cubic to polymeric monoclinic) of Na 2 CsC 60 and the superconductivity in both phases. We have established that the single carbon–carbon bonded polymeric phase of Na

In order to understand the hindered rotational and vibrational dynamics of methane trapped in C{sub 60} interstices and to determine the structure around the interstitial site, they have carried out inelastic neutron scattering studies of the methane

In situ neutron powder-diffraction has been used to probe the Ne content and diffusion kinetics in ${\mathrm{C}}_{60}$ by monitoring the ${\mathrm{C}}_{60}$ lattice parameter vs time following step changes in applied Ne pressure. In the face-centered

Large single crystals of the Tl–Ba–Ca–Cu–O superconductors have been grown from fluxes including up to 30 mol% Rb of the amount of Tl employed. Various phases have been grown with lattice parameters and superconducting properties similar to c

The orientational ordering temperature for methane-intercalated ${\mathrm{C}}_{60}$ is greatly depressed from $\ensuremath{\sim}260\mathrm{K}$ in pure ${\mathrm{C}}_{60}$ to $\ensuremath{\sim}241$ and $\ensuremath{\sim}235\mathrm{K}$ in the stable co

We review the synthesis methods and properties of single crystal, powder, and thin film TlBaCaCuO high-temperature superconducting (Tl-HTS) materials. With transition temperatures ≥ 100 K for several compounds, Tl-HTS materials present real opportu
