Secondary organic aerosol formation from straw burning using an oxidation flow reactor.

Article Synopsis
- The study utilized a Go: PAM reactor to explore how burning wheat straw creates secondary organic aerosols (SOA) by simulating atmospheric oxidation over up to 2.55 days.
- The research found that higher water content in wheat straw significantly increased primary particle emission factors during flaming stages, while the non-flaming stages showed little variation with water content.
- Overall, the study indicated that the enhancement ratios of organic aerosols increased initially with hydroxyl radical exposure before declining, highlighting a significant gap in accurately estimating biomass burning SOA when only considering VOC oxidation.
In the present work, we propose a novel algorithm to determine the scattering coefficient of OA by evaluating the relationships of the MSEs for primary organic aerosol (POA) and secondary organic aerosol (SOA) with their mass concentrations at three distinct sites, i.e. an urban site, a rural site, and a background site in China.

Surface electromyography (sEMG) has been widely used in the study of clinical medicine, rehabilitation medicine, sports, etc., and its endpoints should be detected accurately before analyzing. However, endpoint detection is vulnerable to electrocardiogram (ECG) interference when the sEMG recorders are placed near the heart.
