Thurkow, M. (author), Banzhaf, S. (author), Burler, T. (author), Pultz, J. (author), Schaap, M. (author)Millions of people are exposed to enhanced levels of nitrogen dioxide in urbanized areas, leading to severe health effects. Moreover, nitrogen oxides contribute to the formation of ozone and particulate matter, and as such have wider health related impacts. A substantial reduction of nitrogen oxides may offer considerable health benefits for the...article 2023

(author), Fishwick, J. (author), Yang, M. (author)Global concerns regarding air quality have over the past decade led to the introduction of regulations by the International Maritime Organisation curbing the emissions of sulphur and nitrogen oxides (SOx, NOx). These limits were implemented initially in so-called “emission control areas”, defined where the density of shipping activity combines...article 2023

Holmer, O. (author), Willems, F. (author), Blomgren, F. (author), Eriksson, L. (author)Green zones are challenging problems for the thermal management systems of hybrid vehicles. This is because within the green zone the engine is turned off, and the only way to keep the aftertreatment system warm is lost. This means that there is a risk of leaving the green zone with a cold and ineffective aftertreatment system, resulting in high...conference paper 2020
