A new 3MW ECRH system at 105 GHz for WEST*

Timothy Goodman, Stefano Alberti, Jean-Philippe Hogge, Ioannis Pagonakis, Konstantinos Avramidis

The aim of the WEST experiments is to master long plasma pulses (1000s) and expose ITER-like tungsten wall to deposited heat fluxes up to 10 MW/m2. To increase the margin to reach the H-Mode and to control W-impurities in the plasma, the installation of an ...

Selectively Exciting and Probing Radiative Plasmon Modes on Short Gold Nanorods by Scanning Tunneling Microscope-Induced Light Emission

Olivier Martin, Andreas Stemmer, Yalan Ma

We study the plasmon modes of gold nanorods (as short as similar to 100 nm) on a nonmetallic conductive substrate using scanning tunneling microscope-induced light emission (STM-LE) with a nonplasmonic tungsten tip at room temperature in high vacuum (10-7 ...

Relaxation time shift of Cobalt related internal friction peak in WC-Co cemented carbide

Daniele Mari, Lucas Eric Jacques Degeneve, Samy Adjam

Cemented carbides are widely used in the cutting tools industry for their mechanical properties. They are composite materials made of hard tungsten carbide grains jointed together by a ductile cobalt binder. Due to the extreme conditions of use of the tool ...

FEM of stress partition during compression of WC-10 wt.% Co with realistic 3D morphology

Daniele Mari, Lucas Eric Jacques Degeneve

A Finite Element Model is developed to represent the mechanical behavior of WC-10 wt.% Co in compression tests. In this research, realistic three-dimensional model is obtained by slicing a sample by Focused Ion Beam and reconstituting it, resulting in two ...

In situ work function measurements of W, WO3 nanostructured surfaces

Francisco Sanchez

Surface nanostructuring enables the fabrication of materials with highly desirable properties. Nanostructured tungsten surfaces have potential applications in solar water splitting. Exposing a polished tungsten surface to helium plasma induces various surf ...

Processing and micro-mechanical characterization of multi-component transition MC carbides in iron

Andreas Mortensen, Goran Zagar, Léa Deillon, Marta Fornabaio, Lionel Michelet

We prepare multi-component transition monocarbides of chosen composition by arc-melting together a pre-alloy of the transition metals and cast iron. Based on the elements Ti, Ta, V, Nb and W, 51 different binary, ternary and quaternary compositions are pro ...

Surface Oxygenate Species on TiC Reinforce Cobalt-Catalyzed Fischer-Tropsch Synthesis

Andreas Züttel, Wen Luo, Qian Jiang

Carbide-supported metal catalysts attract extensive research interests owing to the special properties of metal carbide and the interactions between metals and the carbide supports. While surface oxide species are inevitable in carbide materials, their rol ...

Strain glass transition of cobalt phase in a cemented carbide

Daniele Mari, Samy Adjam

Cemented carbides are hard materials used for the fabrication of cutting tools. They consist of hard micron or sub-micron carbide grains held together in a matrix of a tough metallic binder such as cobalt. The understanding and control of cobalt characteri ...
