Abstract

The surface properties of atmospheric aerosol particles largely control their impact on climate by affecting their ability to uptake water, react heterogeneously, and nucleate ice in clouds. However, in the vacuum of a conventional electron microscope, the native surface structure often undergoes chemical rearrangement resulting in surfaces that are quite different from their atmospheric configurations. Herein, we report the development of a cryo-TEM approach where sea spray aerosol particles are flash frozen in their native state and then probed by electron microscopy. This unique approach allows for the detection of not only mixed salts, but also soft materials including whole hydrated bacteria, diatoms, virus particles, marine vesicles, as well as gel networks within hydrated salt droplets. As a result, we anticipate this method will open up a new avenue of analysis for aerosol particles, not only for ocean-derived aerosols, but for those produced from other sources where there is interest in the transfer of organic or biological species from the biosphere to the atmosphere.

Soft matter and nanomaterials characterization by cryogenic transmission electron microscopy

Journal Article Watt, John ; Huber, Dale L. ; Stewart, Phoebe L. - MRS Bulletin

Soft matter has historically been an unlikely candidate for investigation by electron microscopy techniques due to damage by the electron beam as well as inherent instability under a high vacuum environment. Characterization of soft matter has often relied on ensemble-scattering techniques. The recent development of cryogenic transmission electron microscopy (cryo-TEM) provides the soft matter community with an exciting opportunity to probe the structure of soft materials in real space. Cryo-TEM reduces beam damage and allows for characterization in a native, frozen-hydrated state, providing direct visual representation of soft structure. This article reviews cryo-TEM in soft materials characterization and illustrates howmore »« less

The reaction of nitrogen dioxide with sea salt aerosol

Journal Article Weis, D D ; Ewing, G E - Journal of Physical Chemistry A: Molecules, Spectroscopy, Kinetics, Environment, amp General Theory

It is estimated that sea salt is the largest source of tropospheric aerosol particulate matter with 10{sup 12} kg introduced into the atmosphere from wave action over the oceans each year. Recently, considerable attention has been given to heterogeneous reactions between salts and nitrogen oxides and their possible roles in atmospheric chemistry, primarily as potential sources of tropospheric halogens. The reaction of sea salt aerosol with NO{sub 2} under ambient conditions was explored using particles that were generated by atomizing an aqueous solution of synthetic sea salt. The aerosol at 9--30% relative humidity, was mixed with 1--3 mbar of NO{submore »« less

The role of jet and film drops in controlling the mixing state of submicron sea spray aerosol particles

Journal Article Wang, Xiaofei ; Deane, Grant B. ; Moore, Kathryn A. ; ... - Proceedings of the National Academy of Sciences of the United States of America

Covering 71% of the Earth’s surface, oceans represent a significant global source of atmospheric aerosols. The size and composition of sea spray aerosols (SSA) affect their ability to serve as cloud seeds and thus understanding the factors controlling their composition is critical to predicting their impact on clouds and climate. SSA particles have been shown to be an external mixture of particles with different compositions. Film and jet drop production mechanisms ultimately determine the individual particle compositions which are comprised of an array of salt/organic mixtures ranging from pure sea salt to nearly pure organic particles. It is often assumedmore »« less

Mixing states of Amazon-basin aerosol particles transported over long distances using transmission electron microscopy

Journal Article Adachi, Kouji ; Oshima, Naga ; Gong, Zhaoheng ; ... - Atmospheric Chemistry and Physics Discussions (Online)

The Amazon basin is important for understanding the global climate both because of its carbon cycle and as a laboratory for obtaining basic knowledge of the continental background atmosphere. Aerosol particles play an important role in the climate and weather, and knowledge of their compositions and mixing states is necessary to understand their influence on the climate. For this study, we collected aerosol particles from the Amazon basin during the Green Ocean Amazon (GoAmazon2014/5) campaign (February to March 2014) at the T3 site, which locates about 70 km from Manaus, and analyzed using transmission electron microscopy (TEM). TEM has bettermore »« less
