New collaborative publication in ACP on SOA formation from furan

组内消息 2018-06-25

We’re excited to announce the publication of a new article in ACPD. This article provides new information on the roles of NOx level and RH on the formation of SOA from the photooxidation of furan in the presence of NaCl seed particles. Strong evidences indicate that both the RH and different NOx levels have a significant effect on SOA formation.

New smog chamber and new instrument

组内消息 2018-02-03

Our new smog chamber. There are two collapsible 5 m^3 reactors inside the chamber.
smog chamber IAPC
We have acquired a Thermo Q-Exactive mass spectrometry. This instrument has a high-field Orbitrap that combines a resolution of up to 140,000 with high scan speed. The new chamber and Q-Exactive will be used for our secondary organic aerosol research projects.
