11 a.m. (EDT)
45 minutes with an additional 15 minutes for Q & A
Daw Gen Lim and Sebastian Osswald School of Materials Engineering, Purdue University
Vinodkumar Etacheri and Vilas G. Pol School of Chemical Engineering, Purdue University
In this presentation, you will learn —
- How the structure and composition of the wheat starch changes during carbonization.
- How control of temperature affects the structure of the carbonized materials, and thus can be used to maximize energy efficiency in industrial processes.
- How the Raman signals change before and after charge discharge cycling of the battery electrodes.
- How the Raman peak intensity of D and G bands of carbon electrodes changes during Li/Na ion intercalation, which is correlated to structural changes in the electrode.
- How Raman spectroscopy detects the phase transformation of metal oxide based electrodes.
