Seminar - “Towards the Practical Application of Lithium Sulfur Batteries: Electrochemistry and Chemistry” by Dr. Jie Xiao, Pacific Northwest National Laboratory, Richland, Washington 99352, United States

ABSTRACT:  Lithium sulfur (Li-S) batteries have attracted increasing attention because of their high theoretical capacity, natural abundance, low cost and environmental friendliness. Assuming Li2S as the end product, the maximum specific capacity and energy from Li-S batteries are 1675 Ah kg−1 and 2650 Wh kg−1, respectively, significantly higher than those of state-of-the-art lithium ion batteries.

Seminar - “Engineering Anticancer Bacterial Therapies”, by Professor Neil Forbes, Department of Chemical Engineering,University of Massachusetts, Amherst, MA

ABSTRACT:  Engineered bacteria have the potential to overcome the limitations that cause common cancer therapies to fail. Synthetic biology is playing a critical role in the creation of these therapies. We have shown that bacteria, specifically Salmonella, have three main qualities that enable them to overcome the limitations of chemotherapy. Bacteria 1) preferentially target tumors, 2) penetrate tissue, and 3) can kill non-mitotic cells.

Seminar - “Methods for Fast Determination of Lithium Insertion/Extraction Kinetics”, by Steen Brian Schougaard, Université du Québec à Montréal, Département de chimie, Montreal (QC) H3C 3P8, Canada

ABSTRACT:  Arguably, electric and hybrid electric vehicles are the new frontiers for lithium batteries. As a new market it is distinctly different from mass produced microelectronics, not only in the energy per battery unit but also in the power performance requirements. Especially the required charging rates during deceleration and emergency charging, as well as, the discharge rates during startup from standstill are exciting challenges.
