Scientists in Aerosol Research Laboratories conduct a wide range of aerosol research funded by federal agencies using advanced instrumentations. The comprehensive array of measurement tools acquired commercially and developed in house have been employed to investigate transport and transformation of airborne particles in the atmosphere, real-time detection of toxic airborne particles in industrial workplaces, control of engineered nanoparticles, laser ablation for surface decontamination, and lately the impacts of nanoparticles on biological tissues. Supporting infrastructure to the laboratories includes methodologies for high precision particle generation and delivery developed for instrument calibration and aerosol metrology for biological research.
Topic:
A bench-top setup for experiments to improve fundamental understandings of nanoparticle formation by laser ablation using an array of advanced aerosol measurement instruments and computational modeling methods. Project funded by DOE/OBER/EMSP.
A field-portable aerosol plasma spectrometer constructed at ORNL for real-time in-situ measurement of airborne particles from 30 nanometers to several micrometers in size using an electrically enhanced laser induced plasma technique developed by ORNL scientists. Projects funded by SERDP, ESTCP, DOE/FE, DOE/NN, and NNSA/Y12.
A prototype multi-well array exposure chamber developed by ORNL scientists for investigating toxicity of nano particles generated by internal combustion engines and precision fabricated nanostructures. Projects funded by DOE/OTT, AFRL, and ORNL/LDRD.
