About
The Wyslouzil Laboratory studies aerosol science, phase transitions, nucleation, particle growth, nanoparticle structure, and particle formation via electrospray techniques.
The Wyslouzil Group is credited with creating the world's "squarest" ice. This near-perfect cubic arrangement of water molecules is a form of ice that may exist in the coldest high-altitude clouds but is extremely hard to make on Earth. The ability to make and study cubic ice in the laboratory could improve computer models of how clouds interact with sunlight and the atmosphere—two keys to understanding climate change.

Faculty Bio
Barbara Wyslouzil is a Professor of Chemical and Biomolecular Engineering, as well as a Professor of Chemistry and Biochemistry, at the Ohio State University.
She received her B.Sc. in Mathematics and Engineering from Queens University, Kingston Ontario in 1980. From 1981-1986 she worked for the Alberta Research Council, and earned an MSc in Chemical Engineering from the University of Alberta in 1985.
Finally, she obtained her Ph.D. in Chemical Engineering from the California Institute of Technology in 1992.
Her research is best described as fundamental aerosol physics. Topics of interest include developing methods to measure nanoparticle formation, growth, and freezing rates as well as elucidating the structure of multi-component nanoparticles. She also collaborates on projects related to composite polymer nano-particle formation via electrospray techniques for biomedical applications.
She has been actively involved in the American Association for Aerosol Research (AAAR), serving on the executive board as secretary, vice president and president. Her awards include an NSF Career Award and the Kenneth B. Whitby Award from the AAAR. She was recently named a Fellow of AAAR.
Her research was highlighted in the OSU Office of Research Site: 150 Years of Ohio State: Research and Creative Expression Innovators, and her research has been selected by the editors of such publications as Journal of Chemical Physics, Argonne Today, and Chemistry World to be promoted as Featured Articles and Editors’ Picks. She was inducted into the American Association for Aerosol Research as a lifelong fellow in 2018.

Research
Our research projects all contain some aspect or application of aerosol science. Currently we are conducting experiments to probe the microstructure and composition of nanodroplets, and to measure nucleation rates in supersonic nozzles. Models of multicomponent condensation in supersonic flows complement the experimental work. Our group is also active in developing biological and biomedical applications of aerosol science.
The Wyslouzil Group set a new record for creating ice crystals that have a near-perfect cubic arrangement of water molecules—a form of ice that may exist in the coldest high-altitude clouds but is extremely hard to make on Earth.
The ability to make and study cubic ice in the laboratory could improve computer models of how clouds interact with sunlight and the atmosphere—two keys to understanding climate change

Ice Formation Rates
In 2018, Wyslouzil measured the ice formation rates at temperatures near 225 K and found that in this region the temperature dependence of the rates changes dramatically. Our measurements merge smoothly with those at higher and lower temperature but are difficult to predict with standard rate expressions.
Homogeneous nucleation of ice from supercooled liquid water is an important process in ice formation in clouds as well as in technological processes including food preservation. The ability to make and study cubic ice could improve
computer models that enhance our understanding of water and provide keys to understanding climate change.
Even in the liquid state, the composition of multicomponent nanometer-sized droplets is highly non-uniform despite their small size and the relatively short diffusion times. Surface enrichment in aerosols affects the heterogeneous chemistry of aerosol particles as well as nucleation, growth and evaporation kinetics. Our research group uses small angle neutron scattering (SANS) and tunable laser diode absorption spectroscopy (TDLAS) to probe the structure and composition of nanodroplets in order to develop a better understanding of how molecules segregate within aerosol droplets.

In most industrial applications and in the atmosphere, more than one condensible species is present, and the rates of new particle formation and growth may be severely under predicted if interactions between the species are ignored. In our group we use a continuous flow supersonic nozzle apparatus to explore nucleation, condensation, and aerosol evolution at supersaturations and expansion rates that are comparable to those found in turbomachinery, jet exhausts, and steam turbines. By conducting small angle neutron scattering and pressure trace experiments, nucleation rates can be measured that are 6 – 8 orders of magnitude higher than in any other type of equipment.
INSIGHT INTO HETEROGENEOUS CONDENSATION OF CO2 ONTO ALKANE
Barbara Wyslouzil recently explored the heterogeneous condensation of CO2 onto alkane nanodroplets and found that CO2 does not condense until the pressures and temperatures are close to CO2’s extrapolated vapor-liquid equilibrium line and the alkane particles have started to freeze. Depending on the formation process, the resultant particles can adopt a core-shell structure or have CO2 domains in the form of cubes or needles.
Impact: Natural gas can contain significant amounts of CO2 as well as higher hydrocarbons. Supersonic separation is an alternative method to remove condensable material from natural gas. Understanding how and when different constituents in the mixture condense is important to improving the design and operation of these devices.
Our research group also collaborates actively with colleagues on bio-related aerosol problems. Our current research focuses on developing aerosol based delivery systems for tissue therapy.
Our research funders include NSF, ACS, NIH, NATO (travel) and the USDA.
