1. Particulate Formation in Gasoline Direct Injection Engines
Abstract : Gasoline direct injection (GDI) engines are facing a great challenge because of the need to comply with increasingly stringent emission regulations while improving fuel economy. GDI engines are popularly known for their high fuel efficiency (by the standards of gasoline engines) and low emissions, enabling higher compression ratios and thus increased volumetric efficiency.

2. Particulate Formation in GDI Engines
Abstract : The need to comply with stringent emission regulations while improving fuel economy and reducing criteria pollutant emissions from transportation presents a major challenge in the design of gasoline Direct Injection (DI) engines because of the adverse effects of ultrafine Particulate Number (PN) emissions on human health and other environmental concerns. With upcoming advances in vehicle electrification, it may be the case that electric vehicles completely replace all current vehicles powered by internal combustion engines ensuring zero emissions.

3. Valorization of biomass related substrates into value added chemicals : Hydrogen transfer catalysis
Abstract : In the current global scenario, it is evident that global warming and climate change are primarily driven by emissions stemming from the utilization of fossil fuels. Yet, if we look around, most of what we see is made from or linked to fossil fuels and it clearly shows our over-dependency on fossil fuels and hence there is a significant need to develop alternate sources of energy and raw materials to tackle these problems.

5. Properties of oxygen carriers based on natural and waste materials at high degrees of reduction
Abstract : Oxygen carriers play an important role in multiple energy conversion processes, such as chemical-looping technology and oxygen-carrier-aided combustion. This thesis particularly explores how a high reduction degree of an oxygen carrier can affect its performance. READ MORE
