Tracing ultra-fine dust (10/6/2009)

Limit values for fine dust emissions are based on total particle weight. It is the ultra-fine particles, however, that are particularly harmful to health. A new technique separates them by size and identifies their composition -- directly where they arise. ...> Full Article

New X-ray technique illuminates reactivity of environmental contaminants (9/17/2009)

A chemical reaction can occur in the blink of an eye.Thanks to a new analytical method employed by researchers at the University of Delaware, scientists can now pinpoint, at the millisecond level, what happens as harmful environmental contaminants such as arsenic begin to react with soil and water under various conditions. ...> Full Article
