U.S. gains in air quality are slowing down

May 4, 2018

Study indicates challenges of meeting ozone goals After decades of progress in cleaning up air quality, U.S. improvements for two key air pollutants have slowed significantly in recent years, new research concludes. The unexpected finding indicates that it may be more difficult than previously realized for the nation to achieve...

Engineers demonstrate large-scale 'germ trap' solution for hospitals

July 27, 2017

When an infectious airborne illness strikes, some hospitals use negative pressure rooms to isolate and treat patients. These rooms use ventilation controls to keep germ-filled air contained rather than letting it circulate throughout the hospital. But, in the event of an epidemic, these rooms can quickly fill up. Now, a...

Using UAVs and lasers to map atmospheric gases

July 18, 2017

Researchers from the National Institute of Standards and Technology (NIST) and the University of Colorado Boulder have demonstrated a new mobile, ground-based system that could scan and map atmospheric gas plumes over kilometer distances. The system uses an eye-safe laser instrument to send light that “combs” the air to a...

Diesels pollute more than tests detect; excess emissions kill 38,000 yearly

May 16, 2017

Because of testing inefficiencies, maintenance inadequacies and other factors, diesel cars, trucks and buses worldwide emit 4.6 million tons more harmful nitrogen oxide (NOx) than standards allow, according to a new study co-authored by University of Colorado Boulder mechanical engineering researchers. The study , published today in Nature , shows...

David Pfotenhauer

MechE doctoral student works for better air quality in Denver communities

March 20, 2017

When David Pfotenhauer decided to pursue a PhD at CU Boulder, he knew that he wanted to specialize in an application-based science that would allow him get out into communities and use his knowledge to address public issues.

A state-of-the-art gimbal with a custom-built telescope and laser pitch / catch system automatically scans the field for retroreflectors, which are too small to be seen in the distance.

CU Boulder team to track methane leaks using lasers

Targeting Cookstove Pollution Using Supercomputers and NASA Satellites

Jan. 23, 2017

New air quality research is investigating a major, but often overlooked contributor to outdoor pollution and climate: burning of solid fuel for cooking and heating. Cookstove studies typically evaluate how they contribute to indoor air quality issues in houses where solid fuel is frequently used for cooking and heating. A...
