4. Deactivation of after-treatment catalysts for bio-fuelled engines
Abstract : To decrease the emissions of anthropogenic CO2 from vehicles one option is to increase the utilization of biobased fuels. However, there are challenges with this transition, one being the mitigation of emissions of the potent greenhouse gas methane, which is the main constituent of biogas. READ MORE

5. Numerical modelling of particulate matter deposition in exhaust gas after-treatment systems
Abstract : As urban air quality declines, the corresponding levels of particulate matter (PM), that include pollutants such as sulfates, nitrates and black carbon, rise posing the greatest risks to human health. Hence, the control of these particulate emissions constitutes a major global challenge that commands serious attention. READ MORE
