Recent studies have shown that sea spray aerosol has a size-dependent, complex composition consisting of biomolecules and biologically-derived organic compounds as well as salts. This additional chemical complexity most likely influences the heterogeneous reactivity of SSA as these other components will have different reactive sites and reaction pathways. In this study, we focus on the reactivity a class of particles derived from some of the biological components of sea spray aerosol including lipopolysaccharides (LPS) that undergo heterogeneous chemistry within the reactive sites of the biological molecule. Examples of these reactions and the relevant reactive sites are proposed as follows: R-COONa(s) + HNO3(g) → NaNO3 + R-COOH and R-HPO4Na(s) + HNO3(g) → NaNO3 + R-H2PO4. We discuss these results in terms of the detailed knowledge on the acid/base characteristics of sites in gas-phase molecules and thermodynamic driving force for predicting sites of protonation and potentially different reactivities. These reactions may not only be a heterogeneous reaction pathway for sea spray aerosol but for a variety of other types of atmospheric aerosol as well.
This research output has an Altmetric Attention Score of 3. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 03 October 2016.
All research outputs
#21,685,481
of 34,447,360 outputs
Outputs from Journal of Physical Chemistry A
#4,600
of 12,175 outputs
Outputs of similar age
#189,350
of 335,601 outputs
Outputs of similar age from Journal of Physical Chemistry A
#33
of 144 outputs
Altmetric has tracked 34,447,360 research outputs across all sources so far. This one is in the 36th percentile – i.e., 36% of other outputs scored the same or lower than it.
So far Altmetric has tracked 12,175 research outputs from this source. They receive a mean Attention Score of 2.7. This one has gotten more attention than average, scoring higher than 60% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 335,601 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 144 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 77% of its contemporaries.
