8 The likely health and environmental implications associated with atmospheric 9 nanoparticles have prompted considerable recent research activity. Knowledge of the 10 characteristics of these particles has improved considerably due to an ever growing interest in 11 the scientific community, though not yet sufficient to enable regulatory decision making on(More)
Currently, there are no air quality regulations in force in any part of the world to control number concentrations of airborne atmospheric nano-particles (ANPs). This is partly due to a lack of reliable information on measurement methods, dispersion characteristics, modelling, health and other environmental impacts. Because of the special characteristics of(More)
13 Recent Euro–5 and Euro–6 vehicle emission standards are the first ever initiative to 14 control particles on a number basis at the source. Related standards are also desirable 15 for ambient nanoparticles (taken in this article to be those below 300 nm) to protect 16 against possible adverse impacts on public health and the environment. However, 17 there(More)
13 The transport sector is the dominant source of nanoparticles in the urban atmosphere. 14 It is also responsible for about 20–25% of current global CO 2 emissions, a figure that 15 is expected to grow to about 30–50% by 2050 (Fuglestvedt et al., 2008). One option 16 to counter this trend and contribute to the attainment of carbon emission reduction 17(More)
Freshly emitted nanoparticles were found in the car cabin High frequency measurements are needed for better PNC estimation Dilution was found to be the dominant process in car cabin PNC levels in car cabin increased significantly in traffic congestion zones Exposure doses to temporal PNC peaks were up to 380% more than average dose rate. Abstract 8 The aim(More)
This study compared dispersion calculations using a street network model (SIR-ANE) with results from wind tunnel experiments in order to examine model performance in simulating short-range pollutant dispersion in urban areas. The comparison was performed using a range of methodologies, from simple graphical comparisons (e.g. scatter plots) to more advanced(More)
Understanding the transformation of nanoparticles emitted from vehicles is essential for developing appropriate methods for treating fine scale particle dynamics in dispersion models. This article provides an overview of significant research work relevant to modelling the dispersion of pollutants, especially nanoparticles, in the wake of vehicles.(More)

The X(2) holder enables the effective production of thin, electron transparent samples for high-resolution transmission electron microscopy (HRTEM). Improvements to the X(2) holder for high-quality transmission electron microscopy (TEM) sample preparation are presented in this paper. We discuss the influence of backscattered electrons (BSE) from the sample(More)
7 Wind tunnel measurements downwind of reduced scale car models have been made to study the 8 wake regions in detail, test the usefulness of existing vehicle wake models, and draw key 9 information needed for dispersion modelling in vehicle wakes. The experiments simulated a car 10 moving in still air. This is achieved by (i) the experimental(More)
