The Aerosol and Air
Quality Research Laboratory researches "Particulate Systems" - both in
liquids and gases. Areas of application include air pollution control,
environmental nanotechnology and materials synthesis. A focal area of
investigation is "understanding the formation and growth dynamics of
aerosols in high temperature environments". This area encompasses
"combustion aerosols" - the control of toxic species emissions from
combustors (such as coal, waste incinerators, smelters, welding and
foundry operations), conversion of emissions to useful byproducts, and
production of materials such as ceramics, magnetic oxides, doped
semi-conducting photocatalysts, and others.
An area of interest is
the relationship between "nanoparticles" and "health". A recently funded
DOD-MURI project will enable us to collaborate with health scientists to
firmly establish the biological effects of nanoparticles. See article in
the
National Nanotechnology Initiative website.
Charging behavior of
nanoparticles is an important characteristic that needs to be studied to
improve particle collection efficiency and to enable develop more robust
measurement methods. A combination of soft x-ray system with a unipolar
corona has demonstrated a cascading effect in ion generation, and
improvement in charging efficiencies of nanoparticles. Our group has also
developed a novel soft x-ray corona system to capture viral nanoparticles
and completely inactivate them. This project is funded by NIH through the
Midwest Regional Center of Excellence for
Biodefense Research. |
