Oxygen diffusion in garnet: Experimental calibration and implications for timescales of metamorphic processes and retention of primary O isotopic signatures

Anders Meibom, Stéphane Laurent Escrig

Knowledge of oxygen diffusion in garnet is crucial for a correct interpretation of oxygen isotope signatures in natural samples. A series of experiments was undertaken to determine the diffusivity of oxygen in garnet, which remains poorly constrained. The ...

Radio-Frequency Characteristics of Ge-doped Vanadium Dioxide Thin Films with Increased Transition Temperature

Mihai Adrian Ionescu, Andreas Schueler, Igor Stolichnov, Anna Krammer, Teodor Rosca, Matteo Cavalieri, Riyaz Mohammed Abdul Khadar, Andrei Müller, Fatemeh Qaderi Rahaqi

This work investigates and reports on the radio-frequency (RF) behavior in the frequency range of 5 – 35 GHz of germanium-doped (Ge-doped VO2) vanadium dioxide thin films, deposited on silicon substrates via sputtering and pulsed laser deposition (PLD) wit ...

Erbium doped random fiber laser and fiber mixing effect

Luc Thévenaz, Camille Sophie Brès, Can Yao

We demonstrate an active random fiber laser by directly pumping a 100 m erbium-doped fiber at 980 nm wavelength, with a fiber loop mirror forming a half-open cavity. Random lasing with competing spectral modes in the range from 1535 nm to 1560 nm is achiev ...

Temperature-dependent multiangle FTIR NIR-MIR ellipsometry of thermochromic VO2 and V1-xWxO2 films

Andreas Schueler, Rosendo Sanjines, Antonio Paone

VO2 and W-doped VO2 thin films were prepared by Radio Frequency (RF) reactive magnetron sputtering using V-metal target. The amount of W doping was quantified by Rutherford Backscattering Spectrometry (RBS). The optical constants of VO2 and V1-xWxO2 films ...

Colloidal Processing and Yield Stress Modeling Towards Dry Pressed Green Bodies for Transparent Polycrystalline Alumina

Paul Bowen, Michael Stuer

Colloidal processing is a key aspect in modern ceramic processing but most formulations are found empirically. The need for a better knowledge based design of suspension formulation can be achieved by using interparticle potential modelling linked to rheol ...

Atomistic Modeling of Effect of Mg on Oxygen Vacancy Diffusion in alpha-Alumina

Paul Bowen, Ulrich Aschauer, Abhishek Tewari

Oxygen diffusion plays an important role in grain growth and densification during the sintering of alumina ceramics and governs high-temperature processes such as creep. The atomistic mechanism for oxygen diffusion in alumina is, however, still debated; at ...

Genève face à sa mondialité. Anglo-saxons et portugais comme marqueurs de la segmentation spatiale genevoise

Manoug Jérémie Borzakian

Genève, petite ville mondiale connaissant une importante croissance économique et démographique, est ici envisagée par le biais d’une carte sur la répartition des résidents anglo-saxons et portugais du canton. Les logiques spatiales très différentes de ces ...

Electrical property measurements of Cr-N codoped TiO2 epitaxial thin films grown by pulsed laser deposition

László Forró, Arnaud Magrez, Richard Gaal, Jacim Jacimovic

The temperature dependent resistivity and thermo-electric power of Cr-N codoped TiO2 were compared with that of single element N and Cr doped and undoped TiO2 using epitaxial anatase thin films grown by pulsed laser deposition on (100) LaAlO3 substrates. T ...
