A large planetary body inferred from diamond inclusions in a ureilite meteorite

Philippe Gillet, Cécile Hébert, Marco Cantoni, Emad Oveisi, James Badro, Farhang Nabiei, Teresa Katharina Dennenwaldt

Planetary formation models show that terrestrial planets are formed by the accretion of tens of Moon-to Mars-sized planetary embryos through energetic giant impacts. However, relics of these large proto-planets are yet to be found. Ureilites are one of the ...

Linking Morphology and Multi-Physical Transport in Structured Photoelectrodes

Sophia Haussener, Marco Cantoni, Yannick Kenneth Gaudy, Silvan Suter

Semiconductors with complex anisotropic morphologies in solar to chemical energy conversion devices enhance light absorption and overcome limiting charge transport in the solid. However, structuring the solid-liquid interface has also implications on conce ...

In Situ Electric Field Skyrmion Creation in Magnetoelectric Cu2OSeO3

Henrik Moodysson Rønnow, Arnaud Magrez, Marco Cantoni, Fabrizio Carbone, Oleksandr Kriuchkov, Ping Huang, Rajeswari Jayaraman

Exploiting additional degrees of freedom in solid-state materials may be the most-promising solution when approaching the quantum limit of Moore's law for the conventional electronic industry. Recently discovered topologically nontrivial spin textures, sky ...

Applicability of a recently proposed tribocorrosion model to CoCr alloys with different carbides content

Stefano Mischler, Marco Cantoni, Shoufan Cao

Existing sliding tribocorrosion models have been developed for homogeneous passive metals such as stainless steel and pure metals. Many technical alloys contains however second phases, usually much harder than the metallic matrix, intended to provide bette ...

Evolution of 3-D Transport Pathways and Triple-Phase Boundaries in the Ni-YSZ Hydrogen Electrode upon Fuel Cell or Electrolysis Cell Operation

Jan Van Herle, Arata Nakajo, Marco Cantoni, Pierre Burdet

The degradation of the Ni-YSZ electrode was investigated after SOFC or SOEC operation for up to 4,700 h and 10,700 h, respectively. 3-D FIB-SEM serial sectioning combined with 3-D EDS elemental mapping allowed the measurement of structural, material and el ...

Strontium Migration at the GDC-YSZ Interface of Solid Oxide Cells in SOFC and SOEC Modes

Jan Van Herle, Marco Cantoni, Emad Oveisi, Arata Nakajo, Pierre Burdet, Giorgio Rinaldi

Strontium migration from the oxygen electrode to the interface between the electrolyte and interlayer was investigated in solid oxide cells in fuel cell (SOFC) and electrolysis (SOEC) modes. Four samples were imaged by focused ion beam scanning electron mi ...

Structure of precipitates and orientation relationships in Al, Ge, Mo-doped higher manganese silicide crystals

Philippe Buffat, Marco Cantoni, Elena Suvorova Buffat

The structure of Al, Ge, Mo-doped Higher Manganese Silicide (HMS) crystals with the general formulas Mn(Si0.99Ge0.01)(1.75), Mn(Si0.995Ge0.005)(1.75) and (Mn0.98Mo0.02)(Si0.98Ge0.02)(1.75)Al-0.01 was investigated by scanning and transmission electr ...

Stereo-vision three-dimensional reconstruction of curvilinear structures imaged with a TEM

Pascal Fua, Cécile Hébert, Marco Cantoni, Emad Oveisi, Guillaume Lucas, Antoine Letouzey, Sandro Ivo Sebastiano De Zanet

Deriving accurate three-dimensional (3-D) structural information of materials at the nanometre level is often crucial for understanding their properties. Tomography in transmission electron microscopy (TEM) is a powerful technique that provides such inform ...

Effect of surface films on tribologically induced metallurgical transformations of steel in oil lubricated contacts

Stefano Mischler, Marco Cantoni, Shoufan Cao

This study was initiated with the aim to assess the influence of boundary films on the tribologically induced metallurgical transformations and deformations of metals in lubricated contacts and their effect on wear. For this, the tribological behavior of a ...

Spin and valence dependence of iron partitioning in Earth's deep mantle

Cécile Hébert, Philippe Gillet, Marco Cantoni, Farhang Nabiei, James Badro, Hélène Marie Piet, Teresa Katharina Dennenwaldt

We performed laser-heated diamond anvil cell experiments combined with state-of-the-art electron microanalysis (focused ion beam and aberration-corrected transmission electron microscopy) to study the distribution and valence of iron in Earth's lower mantl ...
