The aim of this research project is to study the deposition of thermal atoms and small ionised clusters on well defined surfaces. For this, an installation has been developed at the Institut de Physique Expérimentale to produce mass selected ionic metal cl ...
A systematic study of the mass spectra of particles formed in a supersonic nozzle expansion of Zn, Cd, and Hg vapors together with Na was performed. The particles discussed in this paper contain only 1 heavy atom and
The cytotoxic effect of different concentrations of titanium particles on osteoblasts was studied in vitro. It was found that the viability of the osteoblasts was inversely proportional to the particle concentration. Phagocytosis of particles by the osteob ...
Dust particle contamination is known to be responsible for reduced quality and yield in microelectronic processing. However it may also limit the operation of particle accelerators as a result of beam lifetime reduction or enhanced field emission in radio- ...
We have prepared tailored small arrays of single-domain Ninanomagnets exhibiting an easy-axis perpendicular to the substrate surface. Using ballistic Hall micromagnetometry we probe the magnetization under different tilt angles. For an array of 13 nanomagn ...
To determine self-consistently the time evolution of particle size and their number density in situ multi-angle polarization-sensitive laser light scattering was used. Cross-polarization intensities (incident and scattered light intensities with opposite p ...
The operating diagram of a low quality factor, 8 GHz TE-degrees-01 gyrotron exhibits oscillations between 6.8 and 7.3 GHz. These oscillations are identified as the backward wave component of the TE-degrees-21 traveling mode. As the resonance condition of t ...
A catalytic dispersion of fine metal particles mediates the photodissociation of water into hyrogen gas. A protective agent adsorptive to said particles and selected from among homopolymers, copolymers, hydrocarbyl radicals and polysaccharides stabilizes t ...
