✦ Synopsis

Raman spectroscopy and X-ray diffraction are used to study the effect of heat and Ca 2+ on dimyristoylphosphatidylethanolamine dispersions. Unlike phosphatidylcholine dispersions, dimyristoylphosphatidylethanolamine bilayers (at pH 8) require heating above T m in order for hydration to occur and apparently bind Ca 2Γ· at very low levels. These results are related to models for membrane fusion.

The structure of B-doped natural graphite has been investigated using X-ray diffra~ion and Raman scattering methods. The B-doped graphite has crystai lattice parameters different from those of pristine graphite. The a-axis is elongated and the c-axis contracted by B doping. Furthermore, B doping ind

The stability of the infinite-layer \(\mathrm{SrCuO}_{2}\) upon heating in air has been investigated by high-temperature \(\mathrm{X}\)-ray diffraction. Above \(300^{\circ} \mathrm{C}\) the infinite-layer \(\mathrm{SrCuO}_{2}\) reacted gradually with \(\mathrm{CO}_{2}\) in air to form \(\mathrm{SrCO
