    Article Title: High-resolution mobile monitoring of carbon monoxide and ultrafine particle concentrations in a near-road environment.
    Article Snippet: Assessment of near-road air quality is challenging in urban environments that have roadside structures, elevated road sections, or depressed roads that may impact the dispersion of traffic emissions.. Vehicles traveling on arterial roadways may also contribute to air pollution spatial variability in urban areas.. To characterize the nature of near-road air quality in a complex urban environment, an instrumented all-electric vehicle was deployed to perform high spatialand temporal-resolution mapping of ultrafine particles (UFPs, particle diameter 100 nm) and carbon monoxide (CO).

    Article Snippet: The developed optothermal spectroscopy system uses a pump-and-probe detection principle, where an external cavity quantum cascade laser (EC-QCL Hedgehog, Daylight Solutions) with a tuning range from 8-10.6 μm is focused with a parabolic mirror (MPD169-M03, Thorlabs) and directed onto the sample for mid-IR excitation.
