He added that advances in batteries and fuel cells will require research on composition and design, kinetics of critical processes, and life-limiting processes in cells and their packaging. Faulkner noted that advances in energy conversion and electrosynthesis depend on a better understanding of complex reactions at the electrodes.

Esther Takeuchi, Distinguished Professor and William and Jane Knapp Chair in Energy and the Environment in the Departments of Materials Science and Chemical Engineering and Chemistry at the State University of New York at Stony Brook with a joint appointment at Brookhaven National Laboratory, continued the discussion of energy storage by demonstrating how in situ and operando methods can advance understanding of highly complex electrochemical systems. She began by defining in situ methods as ones that measure a property or material in an intact system and operando methods as ones that probe a system while it is in operation.

Thomas Jaramillo, associate professor of chemical engineering at Stanford University and director of the SUNCAT Center for Interface Science and Catalysis, closed the session on energy conversion by discussing the design of new catalysts and processes for sustainable production of fuels and chemicals. He noted that the rapidly decreasing price of electricity from renewable resources has created new interest in using electrochemical processes for chemical production.

He was interested in exploring electrochemical approaches because they offer a new avenue for reaction discovery given precise potential control, direct generation of radical intermediates, integration of multiple reduction–oxidation events in the same reaction system, external temporal control of a reaction as it proceeds, and opportunities for chemoselectivity and stereoselectivity. He noted that his team used fundamental knowledge of organic chemistry to guide the discovery of new catalysts for electrosynthesis but also used electrochemistry to discover new reactions and to gain a deeper and better understanding of the organic reaction mechanisms.

He closed by emphasizing that electrochemistry has been and remains an essential tool for his research. SESSION II: EDUCATIONAL, RESOURCE, AND OTHER NEEDS TO ADVANCE ELECTROCHEMICAL SCIENCE AND APPLICATIONS -- A PANEL DISCUSSION Panelists: Jeffrey Dick, University of North Carolina; Thomas Jaramillo, Stanford University; Shelley Minteer, University of Utah; Andrew Rappe, University of Pennsylvania; Esther Takeuchi, State University of New York at Stony Brook; and Bill Tumas, National Renewable Energy Laboratory Baran moderated the panel discussion and began by prompting the panelists to provide an "elevator pitch" to demonstrate the importance of electrochemistry.

The difference between a traditional fuel cell and a biofuel cell is that the metal catalyst has been replaced with a biological catalyst. Today, people are experimenting with using microbial fuel cells to treat wastewater; these systems use the oxidation of organic materials in the waste to produce electricity and thus create energy-efficient wastewater treatment.

Stang Presidential Endowed Chair of Chemistry and Distinguished Professor at the University of Utah, continued the discussion begun by Modestino on the opportunities for data science to optimize electrochemical processes. He described the process for using data science in organic chemistry -- first collecting empirical data and data mining, next developing or estimating molecular descriptors and property sets, then conducting supervised learning by using regression tools, and finally converting the "math" to mechanisms and translating to new systems.

. He noted that detecting single entities typically requires nanoelectrodes to enhance sensitivity and described several methods for making them, including using lasers to "pull" wires to small diameters, using scanning electrochemical cell microscopy to activate only a small portion of an electrode, and confining contents to nanodroplets.
