Multivariate statistical analysis as a tool for the segmentation of 3D spectral data

Cécile Hébert, Marco Cantoni, Guillaume Lucas, Pierre Burdet

Acquisition of three-dimensional (3D) spectral data is nowadays common using many different microanalytical techniques. In order to proceed to the 3D reconstruction, data processing is necessary not only to deal with noisy acquisitions but also to segment ...

Three-dimensional chemical analysis of laser-welded NiTi–stainless steel wires using a dual-beam FIB

Michel Rappaz, Aïcha Hessler-Wyser, Marco Cantoni, Pierre Burdet, Jonas Vannod

The biomedical industry has an increasing demand for processes to join dissimilar metals, such as laser welding of NiTi and stainless steel wires. A region of the weld close to the NiTi interface, which previously was shown to be prone to cracking, was fur ...

Imaging of high-Q cavity optical modes by electron energy-loss microscopy

Romuald Houdré, Cécile Hébert, Marco Cantoni, Duncan Thomas Lindsay Alexander, Nicolas Le Thomas

We show a technique that images the intensity distribution and local state of polarization of the optical field of high-quality factor optical modes confined in dielectric planar photonic crystal nanocavities. Based on energy-loss spectroscopy of swift ele ...

Nigrostriatal overabundance of alpha-synuclein leads to decreased vesicle density and deficits in dopamine release that correlate with reduced motor activity

Patrick Aebischer, Graham Knott, Marco Cantoni, Ralf Schneggenburger, Özgür Genç, Jean-Charles Bensadoun, Wojciech Janusz Bobela, Safa Mohanna

alpha-Synuclein (alpha-syn) is a presynaptic protein present at most nerve terminals, but its function remains largely unknown. The familial forms of Parkinson's disease associated with multiplications of the alpha-syn gene locus indicate that overabundanc ...

Hydrogen evolution across nano-Schottky junctions at carbon supported MoS2 catalysts in biphasic liquid systems

Hubert Girault, Xile Hu, Marco Cantoni, Pekka Eero Peljo, Heron Vrubel, Micheal Diarmaid Scanlon, Peiyu Ge

The activities of a series of MoS2-based hydrogen evolution catalysts were studied by biphasic reactions monitored by UV/Vis spectroscopy. Carbon supported MoS2 catalysts performed best due to an abundance of catalytic edge sites and strong electronic coup ...

Light trapping in solar cells: can periodic beat random?

Christophe Ballif, Franz-Josef Haug, Marco Cantoni, Duncan Thomas Lindsay Alexander, Corsin Battaglia, Matthieu Despeisse, Jordi Escarre Palou, Mathieu Gérard Boccard, Karin Söderström, Mathieu Charrière

Theory predicts that periodic photonic nanostructures should outperform their random counterparts in trapping light in solar cells. However, the current certified world-record conversion efficiency for amorphous silicon thin-film solar cells, which strongl ...

Comparison of SOFC cathode microstructure quantified using X-ray nanotomography and focused ion beam scanning electron microscopy

Christos Comninellis, Jan Van Herle, Marco Cantoni, Pietro Tanasini

X-ray nanotomography and focused ion beans scanning electron microscopy (FIB-SEM) have been applied to investigate the complex 3D microstructure of solid oxide fuel cell (SOFC) electrodes at spatial resolutions of 45 nm and below. The application of near e ...

Comparison of X-ray Nanotomography and FIB-SEM in Quantifying the Composite LSM/YSZ SOFC Cathode Microstructure

Christos Comninellis, Jan Van Herle, Marco Cantoni, Pietro Tanasini

X-ray nanotomography and focused ion beam scanning electron microscopy (FIB-SEM) provide unique opportunities to interrogate the 3D microstructure of solid oxide fuel cell (SOFC) electrodes with unprecedented spatial resolution with elemental specificity. ...
