Atmospheric aerosols as prebiotic chemical reactors.

Aerosol particles in the atmosphere have recently been found to contain a large number of chemical elements and a high content of organic material. The latter property is explicable by an inverted micelle model. The aerosol sizes with significant atmospheric lifetimes are the same as those of single-celled organisms, and they are predicted by the interplay of aerodynamic drag, surface tension, ...

Chemical characterization and X-ray absorption spectroscopy

A rapid progress in the theoretical developments based on modulations of absorption cross section due to single and multiple scattering of an electron emitted from an inner shell by X-rays impinging on the target atom to understand the EXAFS and XANES in recent years and harnessing of the highly powerful synchrotron radiation source for the X-rays have bestowed immense capability on X-ray absor...

Characterization of atmospheric aerosols using Synchroton radiation

Characterization of atmospheric particles by electron probe X-ray microanalysis.

Microchemical glass standards were used to validate a quantitation method based on peak-to-background (P/B) ratios from electron probe x-ray microanalysis spectra. This standardless method was applied to the determination of concentrations of individual particles from Malpha or Lalpha lines, as well as from Kalpha lines. The algorithm was tested on particulate glass samples for diameters rangin...
