Ferritic/martensitic steels considered as first-wall candidate materials for fusion reactors experience significant radiation hardening at temperatures below similar to400 degreesC. Experimental evidence suggests that the observed defects are large interst ...
A review of the microstructure of irradiated reduced activation ferritic/martensitic steels is presented, with a focus on F82H. Because of its resistance to irradiation induced hardening, swelling and low irradiation induced temperature shift in the ductil ...
Recent experiments in the Joint European Torus (JET) have provided evidence of sawtooth stabilization by fast ions arising from deuterium neutral beam injection (NBI). A possible theoretical basis for the interpretation of the observed sawtooth period beha ...
L'émergence de procédés de gravure profonde performants (vitesse, anisotropie, uniformité…) de matériaux tels que le silicium (Si), la silice (SiO2) et certains polymères repose sur: • Le développement d'équipement de gravure permettant le contrôle indépen ...
Ionization energies (IE) of [M + zH]z+ (z+) electrospray-produced polypeptides were detd. by electron ionization in a Penning cell of 4.7 and 9.4 .T Fourier transform mass spectrometers. For z = 1+ and substance P, the found IE value of 11.0+-0.4 eV is in ...
This paper reports on the technology development and characterization of polyimide-based, microfluidic channels with integrated nanoporous membranes. A layer transfer and lamination technique is used to fabricate flexible microchannels from spin-on polyimi ...
This paper describes the fabrication of polyimide-based microelectrodes with embedded fluidic microchannels. The thin-film structures combine for the first time a fluidic system with microelectrodes for recording and stimulation of biological signals on a ...
The kinetic energy dependence of ions trapped in a radiofrequency (RF) hexapole ion trap was calcd. as a function of space charge, mean free path, mass, RF potential and charge. The av. kinetic energy of the ions increases with increasing space charge, mea ...
A comparative image simulation and transmission electron microscopy (TEM) study has been addressed in order to assess whether NiAl intermetallic undergoes a crystalline-to-amorphous transformation directly induced by the cascade. For this purpose, an NiAl ...
Using a first-principles approach, we characterize dangling bond defects at Si-SiO2 interfaces by calculating hyperfine parameters for several relaxed structures; Interface models, in which defect Si atoms remain close to crystalline sites of the substrate ...
