A quasielastic neutron scattering and solid-state H-2 NMR spectroscopy study of the polymeric spin-crossover compound {Fe(pyrazine)[Pt(CN)(4)]} shows that the switching of the rotation of a molecular fragment- the pyrazine ...
[EN] The upconversion emissions of yttrium orthoaluminate nano-perovskite co-doped with Er3+/Yb3+ have been studied. Strong green and red upconversion emissions, which can be observed by naked eyes, were observed when ...

The use of sonic crystals (SCs) as environmental noise barriers has certain advantages from both the acoustical and the constructive points of view with regard to conventional ones. However, the interaction between the SCs ...
We report results of experimental and theoretical lattice-dynamics studies on scandium orthovanadate up to 35 GPa. Raman-active modes of the low-pressure zircon phase are measured up to 8.2 GPa, where the onset of an ...

[EN] Highly crystalline pure silica MFI zeolites have been synthesized using tetraethylammonium (TEA), tetraethylphosphonium (TEP), or a mixture of both cations in different proportions as organic structure directing agents ...
Romero García, Vicente; Sánchez Pérez, Juan Vicente; García Raffi, Luis Miguel(Japan Society of Applied Physics, 2012-07-20)
Inverse-designed scattering acoustical elements, called quasi-ordered structures (QOSs), are theoretically and experimentally reported in this work, showing their possibilities as attenuation devices. Multiobjective ...
[EN] The spatial distribution of Sr0.5Ba0.5Nb2O6 nanocrystals is analyzed in a borate-based glass-ceramic by a synchrotron hard X-ray nanoimaging tool. Based on X-ray excited optical luminescence, we examined 2D projections ...
