Nano Research Facility School of Engineering & Applied Science


Welcome to the wonder world of AEROSOLS!

The word aerosol is defined as a gaseous suspension of fine solid or liquid particles.

Aerosols are a lot more than just products that come out of a spray can!  They find application in nanoparticle technology, pharmaceuticals, medicine, electronics, advanced materials, air pollution control, atmospheric issues, global climate, energy and environmental technologies.

Our group, the Aerosol and Air Quality Research Laboratory (AAQRL) is housed in the Department of Energy, Environmental and Chemical Engineering at Washington University in St. Louis. We are involved in research and education related to particulates.

We invite you to take a virtual tour and learn more about us, and the exciting field of Aerosol Science and Engineering.

Lab Tours & Visits

Visitors are welcome to come learn more about the fascinating field of aerosol science and technology, and see nanotechnology projects in action; energy and environmental technologies and others.  Our Laboratory is located in Brauer Hall 3035 (see map here). To schedule a visit, please contact Dr. Biswas


Safety Training

All students and personnel working in the Laboratory should have both EHS Safety Training and Training in Radioactive Materials. Both of these require Annual Refreshers.




MAGEEP 5th Internation Synposium, "The role of research universities in addressing GLOBAL CHALLENGES", October 16, 2014 - October 19, 2014 Visit:


Yang Wang and Jiaxi Fang map out nanometer sized clusters in a flame aerosol reactor (FLAR).  This is the first ever measurement of such clusters during particle formation in a flame aerosol reactor.  See J. of Aerosol Science


Crumpling force on graphene unraveled by Weining Wang. See

Dr. Wang also publishes paper in JACS on Pt activated TiO2 for record high photoreduction rates of carbon dioxide. See 


Professor Biswas wins Award given by American Association for Aerosol Research

Dr. Pratim Biswas was recently awarded the 2013 David Sinclair Award  for sustained excellence in aerosol research and technology by an established scientist.  He was recognized for having a lasting impact in aerosol science research.  This award memorializes David Sinclair, one of aerosol science's greatest innovators known for his knowledge, ingenuity and energy. (See details of the award)

Highlights of AAQRL Projects


AAQRL researches "Particulate Systems" - both in liquids and gases. Areas of application include air pollution control, energy and environmental technology, nanoparticle technology and materials synthesis.


A focal area of investigation is "understanding the formation and growth dynamics of aerosols in high temperature environments".  This area encompasses "combustion aerosols" - the control of toxic species emissions from combustors (such as coal, waste incinerators, smelters, welding and foundry operations), conversion of emissions to useful byproducts, and production of materials such as ceramics, doped semiconducting photocatalysts, and others. 


Please visit our RESEARCH PROJECTS papge to find out more details of our reject projects.


We also develop several educational/self learning modules - for those for the expert to high school students.  Please visit EDUCATION page to learn more.
