LAQR outing to Horsetooth!

The LAQR group spent an afternoon away from their computers, carts and chambers to hike up to the Horsetooth Rock! The Horsetooth Rock is a popular landmark in Fort Collins and at 7,255 feet offers stunning views of the Front Range plains to the east and Rockies to the west. Here is a link to the hike we did:

Senior Design Team at E-Days


The senior design team working at the laboratory presented their final working product at Engineering-Days at the Lory Student Center. The senior design team had worked hard over the past two semesters to build a low-cost, low-power and autonomous air quality monitor that could measure, in real-time, ambient concentrations of carbon dioxide and three other pollutants regulated by the Environmental Protection Agency (carbon monoxide, oxides of nitrogen and ozone). Their efforts paid off and E-Days was a grand success. Congratulations!

VW diesel testing gets highlighted on CBS Denver


Using a portable emissions measurement system (courtesy of Lightning Hybrids, Loveland), we recently tested three VW TDI diesel Jettas to investigate pollutant emissions during on-road tests. We found that all Jettas met the EPA and California’s emissions standard for carbon monoxide (CO) and particulate matter (PM) but exceeded the emissions standard for oxides of nitrogen (NOx). Our work and findings were highlighted in a news segment on CBS Denver.

Welcome Ali, Chris and Liam!

Fall brings in more students! Ali is starting a PhD in Mechanical Engineering and will work on air quality modeling, Liam is an undergraduate researcher who is going to build an environmental chamber and Chris is a senior design student who plans to build an SCR system for a diesel engine and help measure isocyanic acid emissions. Check their profiles out on the Group page.

Studying fresh and ‘aged’ particles from diesel engines, cookstoves and more

DefconIn June 2015, we collaborated with Delphine Farmer in Chemistry and Sonia Kreidenweis and Paul DeMott Atmospheric Sciences to study with the emissions and atmospheric evolution of fine particles or aerosols arising from diesel engines, biomass combustors and cookstoves. We used a broad suite of instruments to measure the size, mass, composition and properties of aerosols; these measurements will allow us to understand the impact of aerosols on air quality, climate and public health. The collage above captures some of the equipment we used and shows the researchers who made this study possible. We are all excited about the data we collected and are can’t wait to test our hypotheses!
