100th Webinar: From Combustion to Non-Equilibrium Electrified Manufacturing for E-fuels & Materials
Combustion Webinar Oct. 16, 2024; Speaker: Yiguang Ju
With the rapid increase of renewable electricity, electrified manufacturing and recycling of e-fuels and materials provides a promising solution to the challenges of intermittency of renewable energy, carbon emissions from fossil fuels, and large-scale energy storage. Plasma provides a wonderful opportunity to control non-equilibrium chemistry not only to enhance combustion at extreme conditions but also to increase the yield and selectivity of e-fuels and material manufacturing and recycling. In this lecture, at first, I will give a brief introduction of electrification for industrial decarbonization and non-equilibrium plasma. Then, e...
