Understanding the relationship between structural characteristics and functional properties of complex relaxor ferroelectric thin films is high interest for designing materials with performances. In this work, structure epitaxial relaxed pulsed-laser-deposited Pb(Mg1/3Nb2/3)O3-xPbTiO3 (PMN-xPT; x = 25, 33, 40) on LaNiO3/SrTiO3 substrates analyzed using a variety diffraction spectroscopic techni...

Introduction: Alteration minerals are important indicators of thermochemical environments at the time of their formation – and thus indicators for the potential habitability of a site [1,2]. Therefore, the detection of alteration minerals, especially nontronite [3], on Mars was an important step to understand Mars’ hydrous history. This initial finding was followed by the detection of a wide va...

Aging rate (AR) of dielectric permittivity (ε33T/ε0) ternary Pb(In1/2Nb1/2)O3–Pb(Mg1/3Nb2/3)O3–xPbTiO3 (PIN–PMN–xPT, x = 26 and 30 mol %) binary Pb(Mg1/3Nb2/3)O3–xPbTiO3 (PMN–xPT, single crystals (SCs) grown by the continuous-feeding Bridgman method (CF-BM) were investigated. The AR was 0.6–2.0 %/decade, whereas that loss SCs 1–8 %/decade. Even though SC growth methods different, CF-BM PMN–30PT...

The specification of access control policies with the XACML language could be an error prone process, so a testing is usually the solution for increasing the confidence on the policy itself. In this paper, we compare two methodologies for deriving test cases for policy testing, i.e. XACML requests, that are implemented in the X-CREATE tool. We consider a simple combinatorial strategy and a XML-...
