This seminar will discuss the ideality and reality of low carbon sustainable energy options. The technical challenges for the development of energy efficient advanced engines and high energy density lithium ion batteries will be briefly reviewed. The recent discoveries of low temperature flames such as cool flames and warm flames and their impacts on engine knocking, turbulent flame burning rates, and alternative fuel development will be summarized. Control of low temperature ignition and combustion by using non-equilibrium plasma and plasma-combustion instability will be highlighted. Measurements of rate limiting kinetics in plasma assisted low temperature combustion will be briefly discussed. The opportunity to use low temperature flames for the synthesis of high energy density lithium ion battery cathode materials will be introduced.
