Fast response sequential measurements and modelling of nanoparticles inside and outside a car cabin

This EPSRC–funded research presents novel fast response measurements, revealing rapid transformation processes acting on nanoparticles within and outside moving vehicles. A fast parameterised dispersion model was developed to compute nanoparticle concentrations penetrating into the car–cabins from other on–road vehicles. These new findings and the model represent a valuable tool for scientific community, policy makers, and regulatory authorities to assess nanoparticle exposure of car passengers and design mitigation measures. This work triggered new ideas and collaboration to win an acclaimed (http://www.ukieri.org/images/pdf/success-story-surrey-IIT-Delhi.pdf) UK–India Education and Research Initiative grant, and winning Commonwealth PhD fellowship to extend this research strand.
