Flexible porous coordination polymers change their structure in response to molecular incorporation but recover their original configuration after the guest has been removed. We demonstrated that the crystal downsizing of twofold interpenetrated frameworks of [Cu(2)(dicarboxylate)(2)(amine)](n) regulates the structural flexibility and induces a shape-memory(More)
Characteristics of thickness-shear modes excited by two-layer piezoelectric film in acoustic sensors Surface effects on the wrinkling of piezoelectric films on compliant substrates Thickness effect on nanoscale electromechanical activity in Pb(Mg1/3Nb2/3)O3-PbTiO3 thin films studied by piezoresponse force microscopy Harmonic modulation behavior in lead(More)
We report the successful heteroepitaxial growth of perfectly oriented hybrid MOF thin films. By employing step-by-step liquid-phase epitaxy (LPE), [Zn(2)(ndc)(2)(dabco)](n) was grown on [Cu(2)(ndc)(2)(dabco)](n), thus demonstrating that the MOF-on-MOF deposition scheme developed for powdered microcrystalline MOF materials can also be applied in connection(More)
Ferroelectricity and Curie temperature are demonstrated for epitaxial Y-doped HfO2 film grown on (110) yttrium oxide-stabilized zirconium oxide (YSZ) single crystal using Sn-doped In2O3 (ITO) as bottom electrodes. The XRD measurements for epitaxial film enabled us to investigate its detailed crystal structure including orientations of the film. The(More)
We have developed new microdiffraction system at the SPring-8. This system used a focused beam produced using a phase zone plate combined with a narrow slit, which made a focused beam with a small size and a small angular divergence. Furthermore we can use the two-dimensional x-ray CCD detector, which enable us to measure local reciprocal space maps at many(More)
Coherent X-ray diffraction techniques play an increasingly significant role in the imaging of nanoscale structures, ranging from metallic and semiconductor to biological objects. In material science, X-rays are usually considered to be of a low-destructive nature, but under certain conditions they can cause significant radiation damage and heat loading on(More)
Recently, it has been revealed that properties of ferroelectric nanostructures depend on their size. The depolarization field has been considered as one of the major factors, which cause &#x201C;size effect&#x201D;. In this study, we investigated the influence of the depolarization field on the domain structure in tetragonal Pb(Zr,Ti)O<sub>3</sub>(PZT)(More)
To reveal the origin of the CO oxidation activity of Ruthenium nanoparticles (Ru NPs), we structurally characterized Ru NPs through Rietveld refinement analysis of high-energy X-ray diffraction data. For hexagonal close-packed (hcp) Ru NPs, the CO oxidation activity decreased with decreasing domain surface area. However, for face-centered cubic (fcc) Ru(More)
