Procedure for rapid determination of nickel, cobalt, and chromium in airborne particulate samples [PDF]

open access: yes
A rapid, selective procedure for the determination of 1 to 20 micrograms of nickel, chromium, and cobalt in airborne particulates is described. The method utilizes the combined techniques of low temperature ashing and atomic absorption spectroscopy.

Quantitative speciation of Mn-bearing particulates emitted from Autos burning (methylcyclopentadienyl)manganese tricarbonyl-added gasolines using XANES spectroscopy

open access: yes, 2000
The chemical nature of Mn-containing particulates emitted from (methylcyclopentadienyl)manganese tricarbonyl-added gasoline engines has been elucidated using Mn K-edge X-ray absorption fine structure (XAFS) spectroscopy.

Particulate Measurement Methods

open access: yes, 2003
The presence of soot is essential in some processes: it is the product in carbon black; it provides the source of light radiation in pyrotechnic and pyrophoric flares; and is the dominant source of radiant heat transfer in boilers and furnaces. However, it is also an undesirable product in many combustion processes where it is expelled with the exhaust,

Particulate airborne impurities [PDF]

open access: yes, 2013
The cumulative effects of air pollutants are of principal concern in research on environmental protection in Sweden. Post-industrial society has imposed many limits on emitted air pollutants, yet the number of reports on the negative effects from them is

Optical signatures of molecular particles via mass-selected cluster spectroscopy [PDF]

open access: yes, 1990
A new molecular beam apparatus was developed to study optical absorption in cold (less than 100 K) atomic clusters and complexes produced by their condensation with simple molecular gases.
