Characterization of New Particle Formation in Soft X-ray Radiolysis Reactor: AMCs-to-Secondary Inorganic Aerosols

New Performances of Soft X-ray Spectrometry (leeixs) in Surface Analysis of Organic and Inorganic Materials

Capabilities of low-energy electron induced x-ray spectrometry (LEEIXS) in surface and very thin film analysis are illustrated by examples dealing with films of organic and inorganic materials deposited on different metallic substrates from liquid or vapour phases (chemisorption, electrodeposition, plasma polymerization . ..). In addition, these examples point out the sensitivity of the techniq...

Measurements of secondary inorganic aerosols in the Netherlands

Effect of heterogeneous aqueous reactions on the secondary formation of inorganic aerosols during haze events

The effect of heterogeneous aqueous reactions on the secondary formation of inorganic aerosols during haze events was investigated by analysis of comprehensive measurements of aerosol composition and concentrations [e.g., particular matters (PM2.5), nitrate (NO3), sulfate (SO4), ammonium (NH4)], gas-phase precursors [e.g., nitrogen oxides (NOx), sulfur dioxide (SO2), and ozone (O3)], and releva...

Optimum driving a Z-pinch for soft X-Ray lasers

A capillary plasma z-pinch as an alternative active medium of soft X-Ray lasers was studied experimentally and theoretically. The theoretical analysis was based on the self consistent solution of the so called “snow plow” model. The dynamics of pinched plasma is determined by the capillary parameters and by the time dependence of electrical current passing through it. The current time dependenc...

New Bright Soft X-ray Selected Rosat Agn: I. Infrared–to–x-ray Spectral Energy Distributions

We present results of an infrared-to-X-ray study of 76 bright soft X-ray selected Seyfert galaxies discovered in the ROSAT All-Sky Survey. These objects are characterized by steep X-ray spectra in the 0.2-2.0 keV bandpass with power law energy spectral indices in the range of 1.3 to 8 and a lack of internal absorption by neutral hydrogen. Our sample selection based on hardness ratio yields a me...
