TL;DR: In this article, three analytical studies of base-isolated structures are carried out, and the effect of isolation damping on the performance of different isolation systems under near-fault motion is investigated.
Abstract: Three analytical studies of base-isolated structures are carried out. First, six pairs of near-fault motions oriented in directions parallel and normal to the fault were considered, and the average of the response spectra of these earthquake records was obtained. This study shows that in addition to pulse-type displacements, these motions contain significant energy at high frequencies and that the real and pseudo-velocity spectra are quite different.
The second analysis modelled the response of a model of an isolated structure with a flexible superstructure to study the effect of isolation damping on the performance of different isolation systems under near-fault motion. The results show that there exists a value of isolation system damping for which the superstructure acceleration for a given structural system attains a minimum value under near-fault motion. Therefore, although increasing the bearing damping beyond a certain value may decrease the bearing displacement, it may transmit higher accelerations into the superstructure.
Finally, the behaviour of four isolation systems subjected to the normal component of each of the near-fault motions were studied, showing that EDF type isolation systems may be the optimum choice for the design of isolated structures in near-fault locations.

TL;DR: In this article, the crystal structure of the new fast oxide-ion conductor La2Mo2O9 (ionic conductivity of 0.06 S cm-1 at 800 °C) has been studied.
Abstract: The crystal structure of the new fast oxide-ion conductor La2Mo2O9 (ionic conductivity of 0.06 S cm-1 at 800 °C) has been studied. This compound presents a reversible phase transformation around 580 °C from a low-temperature form α-La2Mo2O9 to a high-temperature form β-La2Mo2O9. The high-temperature form β-La2Mo2O9 has a cubic structure (at 617 °C, space group P213; a = 7.2014(5) A; Z = 2; RBragg = 5.8%, Rp = 10.9%, Rwp = 6.5%, χ2 = 7.7) which derives from that of β-SnWO4. Partial site occupation by oxygen atoms, strongly anisotropic thermal factors, and short-range order with a distance characteristic of O−O pairs have been evidenced. An original concept is proposed for the origin of oxide−ion conduction in this compound, which could be applied to the design of new oxide−ion conductors. The low-temperature form α-La2Mo2O9 exhibits a slight monoclinic distortion and a large superstructure relative to β-La2Mo2O9 (2 × 3 × 4), most probably due to the localization of oxygen atoms. The large cell (∼8800 A3) d...

TL;DR: In this article, the synthesis and properties of a new lithium-ordered superstructure of Li0.0625V2O5 through controlled prelithiation treatment are reported.
Abstract: Vanadium pentoxide (V2O5) is an attractive high-capacity cathode material for lithium-ion batteries but is limited by the poor structural stability. In this work, we report the synthesis and properties of a new lithium-ordered superstructure of Li0.0625V2O5 through controlled prelithiation treatment. Compared to VO5 square pyramids in a pure α-V2O5 structure, the distorted VO5 square pyramid in this superstructure imparts an intrinsic layer structure with improved stability, expanded c-plane spacing, as well as expansion in the a-axis. In the voltage range of 2.5–4.0 V vs Li/Li+, Li0.0625V2O5 nanobelts with lithium-ordered superstructures exhibit a specific capacity up to 215 mAh g–1, ultrahigh cycling capability, and high rate capability. Cyclic voltammograms of lithium insertion into Li0.0625V2O5 nanobelts also demonstrate two new pairs of reversible pseudocapacitive peaks in addition to the ordinary peaks of Li+ insertion into the pure orthorhombic α-V2O5.
