Electromechanical properties of Al0.9Sc0.1N thin films evaluated at 2.5 GHz film bulk acoustic resonators

Paul Muralt, Evgeny Milyutin, Ramin Matloub Aghdam, Silviu Cosmin Sandu, Alvaro Artieda

AlN films are employed in RF filters for wireless communication. We report on enhanced coupling factors k(t)(2) obtained by partial substitution of Al by Sc. Al0.88Sc0.12N films were deposited by reactive magnetron sputtering from an Al0.9Sc0.1 alloy targe ...

Rigorous Integration of Inertial Navigation with Optical Sensors by Dynamic Networks

Jan Skaloud, Denis Rouzaud

This paper presents a new concept for simultaneous modeling and adjusting of raw inertial observations with optical and (if available) GNSS data streams. The presented post-mission procedure of dynamic networks allows treating dynamic (e.g. inertial) and s ...

Synthesis of Unusual Oxime Ethers by Reaction of Tetranitromethane with B-Alkylcatecholboranes

Philippe Renaud, Kurt Schenk

The reaction of tetranitromethane with B-alkylcatecholboranes leads to the formation of unusual dinitrooxime ethers. A tentative mechanism is provided, which suggests the involvement of extremely fast addition of alkyl radicals to tetranitromethane. The su ...

Improved stability of La0.5Sr0.5FeO3 by Ta-doping for oxygen separation membrane application

Jan Van Herle, Stefan Diethelm, Defne Bayraktar

(La,Sr)FeO3 mixed conducting perovskites are considered as interesting candidates for oxygen separation membranes but they suffer from limited structural stability in a large oxygen partial pressure (pO2) gradient, because of their propensity for chemical ...

Characterisation of phases in nanostructured, multilayered titanium alloys by analytical and high-resolution electron microscopy

Philippe Buffat

Surface processing of a Ti–6Al–4V alloy led to a complex multilayered microstructure containing several phases of the Ni–Ti–P–Al–O system, which improves the mechanical and tribological surface properties. The microstructure, chemical and phase composition ...

Oxygen transport in La0.5Sr0.5Fe1-yTi yO3-δ (y=0.0,0.2) membranes

Jan Van Herle, Stefan Diethelm, Defne Bayraktar

The influence of partial substitution of Fe with Ti on the oxygen transport properties of La1- xSrxFeO3 membranes was investigated in view of their application for oxygen separation. Samples of composition La0.5Sr0.5 Fe1-yTiyO3-δ (y = 0, 0.2) were prepared ...

Ionic liquids based on imidazolium salts incorporating a nitrile functionality

Paul Joseph Dyson, Zhaofu Fei, Dongbin Zhao

Novel chemical compounds of the general formula KA, in which K is a 5- or 6- membered heterocyclic ring having 1-3 hetereo atoms, which can be independently N, S, or 0 with the proviso that at least one of the hetereo atoms must be a quaternized n ...
