What is it about?
We explored the properties of particles produced from automotive disk brakes in a laboratory setting and found that the particles can be highly charged. As many as 80% of particles emitted from some brakes have at least some charge.

Why is it important?
Brake wear particles is an important source of air pollution that will grow in significance as we transition to alternative fuels. Research has shown that these particles are harmful to human health and the environment. The observation that these particles are charged provides insights into their fate in the atmosphere as well as a possible means for removing these particles before they are emitted.
