Thermal effects in the Long-Term Monitoring of Bridges

Olivier Burdet

Daily and seasonal temperature variations induce deflections of bridges. The amplitude of these moments is significant in comparison with the yearly increment caused by irreversible long-term deflections. To improve the quality of the interpretation of mon ...

Investigations on Axial Compressor Cascades with Aspiration on Blades and Hub

Peter Ott, Elia Colombo, Cécile Deslot

This document presents an overview of the investigations performed within the project NEWAC on the application of active flow control by aspiration to axial compressors. It is based on the measurements performed on different annular cascades, tested in the ...

Anomalous dielectric peak in Mg and Li doped ZnO ceramics and thin films

Nava Setter, Alexander Tagantsev

In this manuscript we report dielectric measurements of Mg and Li doped ZnO ceramics and thin films of various compositions. We have tried to reproduce the reported ferroelectriclike behavior in doped ZnO ceramics and thin films and observed anomalous diel ...

High coupling materials for thin film bulk acoustic wave resonators

Janine Conde

Radio frequency (RF) filters based on bulk acoustic wave resonances in piezoelectric thin films have become indispensable components in mobile communications. The currently used material, AlN, exhibits many excellent properties for this purpose. However, i ...

Noncentrosymmetric phase of submicron NaNbO3 crystallites

Arnaud Magrez

The temperature and pressure characteristics of a noncentrosymmetric crystal modification of NaNbO3 were studied by Raman spectroscopy. A transition towards the bulk-like structure of NaNbO3 occurs in the temperature range from 280 to 360 °C. High-pressure ...

Temperature-induced Phase Transitions in Micro-, Submicro-, and Nanocrystalline NaNbO3

Arnaud Magrez

Phase transitions in micro-, submicro-, and nanocrystalline NaNbO3 were investigated by temperature-tuning Raman spectroscopy and X-ray powder diffraction method. Three powders with different average particle size showed successive phase transitions within ...

T-shaped microcantilever sensor with reduced deflection offset

Luis Guillermo Villanueva Torrijo

The authors have designed and fabricated arrays of microcantilevers with a geometry that shows reduced initial angular offset and angle deviation between the cantilevers of the array. This feature allows to detect the displacement of the cantilevers using ...

Phase transitions, anisotropy and domain engineering

Matthew Davis

Relaxor-ferroelectric single crystals PZN-xPT [(1-x)Pb(Zn1/3Nb2/3)O3-xPbTiO3] and PMN-xPT [(1-x)Pb(Mg1/3Nb2/3)O3-xPbTiO3] continue to attract much interest due to their anomalously large piezoelectric properties (d33 > 2000 pm/V; k33 > 90%) when poled ("do ...

Pulsed laser deposition of (SrBa)Nb2O6 thin films and their properties

Anna Infortuna

Strontium barium niobate (SrxBa1-xNb2O6, shortly SBN) is a solid solution system with tetragonal tungsten bronze crystal structure. It exhibits a ferroelectric phase with only one polar axis and a transition temperature depending on the Sr/Ba ratio. This t ...

Physical model of retention and temperature-dependent polarization reversal in ferroelectric films

Nava Setter, Alexander Tagantsev, Igor Stolichnov, Enrico Colla

The phenomenon of time-dependent polarization loss in poled ferroelectric capacitors, also known as retention, represents one of the most important reliability issues for ferroelectric nonvolatile memories. In a number of publications different ways to con ...
