Individual aerosol particles from biomass burning in southern Africa: 2, Compositions and aging of inorganic particles
[1] Individual aerosol particles collected over southern Africa during the SAFARI 2000 field study were studied using transmission electron microscopy and field-emission scanning electron microscopy.Expand
Atmospheric tar balls: Particles from biomass and biofuel burning
[1] “Tar balls” are amorphous, carbonaceous spherules that occur in the tropospheric aerosol as a result of biomass and biofuel burning. They form a distinct group of particles with diametersExpand
Individual aerosol particles from biomass burning in southern Africa: 1. Compositions and size distributions of carbonaceous particles
[1] Individual aerosol particles in smoke plumes from biomass fires and in regional hazes in southern Africa were studied using analytical transmission electron microscopy (TEM), which allowedExpand
Influence of sea-salt on aerosol radiative properties in the Southern Ocean marine boundary layer
There has been considerable debate about the relative importance of sea-salt and sulphate from non-sea-salt sources in determining aerosol radiative effects in the marine boundary layer. In theExpand
Magnetite from magnetotactic bacteria; size distributions and twinning
We studied intracellular magnetite particles produced by several morphological types of magnetotactic bacteria including the spirillar (helical) freshwater species, Magnetospirillum magnetotacticum,Expand
Soot and sulfate aerosol particles in the remote marine troposphere
Sulfate aerosol particles containing soot aggregates were observed in the marine troposphere in both hemispheres under conditions that ranged from extremely clean to heavily polluted. Even in cleanExpand
A Cultured Greigite-Producing Magnetotactic Bacterium in a Novel Group of Sulfate-Reducing Bacteria
The crystal structure of biomineralized magnetic nanocrystals depends on environmental and genetic factors. Magnetotactic bacteria contain magnetosomes—intracellular, membrane-bounded, magneticExpand

Aerosol particles are ubiquitous in the troposphere and exert an important influence on global climate and the environment. They affect climate through scattering, transmission, and absorption ofExpand
Nature and climate effects of individual tropospheric aerosol particles
Aerosol particles in the atmosphere exert a strong influence on climate by interacting with sunlight and by initiating cloud formation. Because the tropospheric aerosol is a heterogeneous mixture ofExpand
Reaction sequence of iron sulfide minerals in bacteria and their use as biomarkers.
Some bacteria form intracellular nanometer-scale crystals of greigite (Fe3S4) that cause the bacteria to be oriented in magnetic fields. Transmission electron microscope observations showed thatExpand
