Particle Size Effects in Ru/CNF Catalysts during Supercritical Water Gasification of Glycerol

Frédéric Vogel, Oliver Kröcher, David Baudouin, Ayush Agarwal

Ru/CNF catalysts of different Ru nanoparticle (NP) sizes (0.9-2.7 nm) were assessed for their performance in continuous supercritical water gasification (SCWG) of glycerol. A structure sensitivity of Ru was demonstrated, with high initial turnover frequenc ...

Investigating active phase loss from supported ruthenium catalysts during supercritical water gasification

Frédéric Vogel, Oliver Kröcher, David Baudouin, Mohamed Tarik

Active phase loss mechanisms from Ru/AC catalysts were studied in continuous supercritical water gasification (SCWG) for the first time by analysing the Ru content in process water with low limit-of-detection time-resolved ICP-MS. Ru loss was investigated ...

Conformal Deposition of Conductive Single-Crystalline Cobalt Silicide Layer on Si Wafer via a Molecular Approach

Giovanni De Micheli, Pierre-Emmanuel Julien Marc Gaillardon, Tsung-Han Lin, David Baudouin, Olha Sereda

The realization of metal-semiconductor contacts plays a significant role in ultrascaled integrated circuits. Here, we establish a low-temperature molecular approach for the conformal deposition of a 20-nm Co-rich layer on Si (100) wafers by reaction in sol ...

Low Temperature Wet Conformal Nickel Silicide Deposition for Transistor Technology through an Organometallic Approach

Giovanni De Micheli, Michele De Marchi, Pierre-Emmanuel Julien Marc Gaillardon, Tsung-Han Lin, Maxime Victor Thammasack, David Baudouin

The race for performance of integrated circuits is nowadays facing a downscale limitation. To overpass this nanoscale limit, modern transistors with complex geometries have flourished, allowing higher performance and energy efficiency. Accompanying this br ...

Phenylazide Hybrid-Silica - Polarization Platform for Dynamic Nuclear Polarization at Cryogenic Temperatures

Geoffrey Bodenhausen, Sami Jannin, Aurélien Bornet, Jonas Milani, Basile Vuichoud, David Benjamin Roger Antoine Gajan, David Baudouin

Hyperpolarization of NMR-active nuclei is key to gather high quality spectra of rare species and insensitive isotopes. We have recently established that silica-based materials containing regularly distributed nitroxyl radicals connected to the silica matri ...

Structured and porous materials particularly suitable as polarizing agents in dissolution dynamic nuclear polarization

Geoffrey Bodenhausen, Sami Jannin, Aurélien Bornet, David Benjamin Roger Antoine Gajan, David Lyndon Emsley, David Baudouin

The present invention concerns materials consisting in a porous and structured network, this network being at least in part formed by Si atoms, or Si atoms and metal atoms, linked to each other by oxy bridges, comprising organic molecules which include at ...
