Top Tweets for #Sub3nm
Researchers from @INAR_fin @AerosolTau @hsy_fi and @IlmaTiede developed a new method to determine the relative contributions of atmospheric new particle formation and traffic to the sub-3 nm particle population in different urban environments

In Finland researchers teamed up to measure 1-800 nm particles and several gaseous compounds at an urban street canyon and a nearby background station—read about it in the Airmodus Newsletter:

"This study shows that whenever we encounter ozone indoors, where we spend most of our lives, NCAs will be produced in the air around us."
@licinadusan @CJWeschler @NijingWang @MengzeLi3 @VanhanenJoonas et al.

Finally I can share this one: "Ozone Initiates Human-Derived Emission of Nanocluster Aerosols". So having people indoors with ozone can trigger particle formation through ozone + human skin lipid chemistry @licinadusan @CJWeschler @WargockiPawel : https://t.co/dAUvOprNfS
Wallace et al. have studied ultrafine particles (2.3‐64 nm) from burning candles in a residence: number concentration peaked in the #sub3nm particle sizes, and to see the whole picture, even smaller particles (<2 nm) should be measured.
@LanceWallace3 @RimIAQ @PSU_AE @penn_state
Burning candles indoors produce sub 10nm particles: "...increased particle production for the very smallest particles (2.33‐2.50 nm) suggests that even smaller particles may be important to study" #IAQ #IndoorChem @IndoorChem

How cool is this!? Our A11 must have the most comfortable seat @EAC20191! 😉
Want to see the @airmodus nCNC? Take a look in the #Volvo downstairs!

Growth of atmospheric/other aerosol particles in the single-digit nm sizes is a process sensitive to not only conditions of the environment, but also the composition of the particle itself.... 1/3

"Recent studies have shown that a significant fraction of traffic-related particles are only few nanometers in diameter.”
(Nanocluster aerosol (NCA), particle diameter 1.3-4 nm)

"The lifetime of smallest, nanocluster aerosol (NCA) particles is longer than expected. ...NCA may play a significant role in urban environments”

Nanokokoiset hiukkaset säilyvät ilmakehässä odotettua pidempään. #Liikenne-päästöjä selvittäneet tutkijat arvioivat, että näiden aivan pienimpien hiukkasten #ilmanlaatu- ja #terveys-vaikutukset ovat kaupunkiympäristössä suuremmat kuin on aiemmin oletettu. https://t.co/0duEGhmydW
NCA contributes both to health and climate effects of vehicle emissions. Kangasniemi et al. and Järvinen et al. featured in the latest Airmodus Newsletter: https://t.co/emDYGT0ibg

New research on nanocluster aerosol from traffic, Kangasniemi et al. @TampereUni
"A large amount of NCA survives the initial transformation processes after being emitted from traffic.”

"...we conclude that NCA may play a significant role in urban environments, since, rather than being scavenged by larger particles, NCA particles remain in the particle population and grow by condensation." Kangasniemi et al: https://t.co/NiRhgmeWdA
@ElaMietti @ethnpc @VanhanenJoonas Are any of your team coming to https://t.co/RVpNGPe708 later this month? Would love to meet there. #Nanoparticles #Nanopollution #sub3nm
Also @ethnpc next week: @VanhanenJoonas presenting number concentration measurements of #nonvolatile #sub3nm particles emitted by a GDI engine. At 4000 rpm highest conc. in 1-3 nm size range. Most of the sub-3nm #particles don’t evaporate in 400oC
#1nm #emissions #aerosolscience
@ethnpc next week: Henna Lintusaari from @TampereUni presenting a poster of #nonvolatile #sub23nm particle number concentrations in a street canyon; simultaneous measurements of >23 nm, >10 nm, >3 nm, and >1.4 nm #particles. Highest concentrations during morning rush hour.

@jksmith34 @airmodus @INAR_fin @VanhanenJoonas @janette_m1 Great that you mentioned this! In this setup there are particle counters with cut-offs ranging from 1.3 nm to 20 nm, so these measurements will give size and particle number info of those small particles as well.

Yes, now #sub3nm detection, counting, & dispersion modeling. That's a trick that @CERN laughs at & we only #DreamOutLoud about. Hey! @TfL truth is stranger than fiction. Start measuring #UFP before a tweet finds the right lawyer who sues the hell out of everyone! @rosamund_ElsFdn
@jksmith34 Exactly, if you don't look you won't know if it's there.
In 2017 Rönkkö et al. showed that a major fraction of particles emitted by road transportation are in a previously unmeasured size range of 1.3–3.0 nm.
