Structure of mercaptobiphenyl monolayers on mercury
Article Abstract:
The molecular-scale structure and phase behavior of single-component Langmuir films of 4'-methyl-4-mercaptobiphenyl (MMB) and 4'-perfluoromethyl-4-mercaptobiphenyl (FMMB) on mercury are studied using surface tensiometry, grazing incidence X-ray diffraction, and X-ray reflectivity. The differences in the structure are discussed and traced to the differences in the substrate's surface structure, and in the molecular cross section and rigidity.

Trivalent atom contribution on solid-solid transformation of Ga13 polycation intercalated clay into sodalite investigated by X-ray absorption spectroscopy
Article Abstract:
Solid-solid transformation mechanism of Ga Keggin-type ion intercalated clay into sodalite is clarified by X-ay diffraction (XRD), FT-IR spectroscopy, and X-rayabsorption spectroscopy (XAS). The elucidation of the formation mechanism of Ga-O-Si species shows that the solid-solid transformation is strongly influenced by the trivalent cations, which are rapidly changed in the environment, followed by reacting with the silicate network of clay.

Metallic ReO3 nanoparticles
Article Abstract:
ReO3 nanoparticles in the diameter range of 8.5-32.5 nm are prepared by decomposition of the Re2O7-dioxane complex under solvothermal conditions and characterized by X-ray diffraction, electron microscopy, optical spectroscopy, and scanning probe microscopy. The nanoparticles have the cubic (Pm3m {221} space group) structure with the lattice parameter increasing with decreasing size.
