Description:

This month, Nate Lewis will discuss, “Sunlight-Driven Hydrogen Formation by Membrane-Supported Photoelectrochemical Water Splitting.”

We are developing an artificial photosynthetic system that will utilizes sunlight and water as the inputs and produce hydrogen and oxygen as the outputs. We are taking a modular, parallel development approach in which three distinct primary components-the photoanode, the photocathode, and the product-separating but ion-conducting membrane-are fabricated and optimized separately before assembly into a complete water-splitting system. The design principles incorporate two separate, photosensitive semiconductor/liquid junctions that will collectively generate the 1.7-1.9 V at open circuit necessary to support both the oxidation of H2O (or OH-) and the reduction of H+ (or H2O). The photoanode and photocathode will consist of rod-like semiconductor components, with attached heterogeneous multi-electron transfer catalysts, which are needed to drive the oxidation or reduction reactions at low overpotentials. The high aspect-ratio semiconductor rod electrode architecture allows for the use of low cost, earth abundant materials without sacrificing energy conversion efficiency due to the orthogonalization of light absorption and charge-carrier collection. Additionally, the high surface-area design of the rod-based semiconductor array electrode inherently lowers the flux of charge carriers over the rod array surface relative to the projected geometric surface of the photoelectrode, thus lowering the photocurrent density at the solid/liquid junction and thereby relaxing the demands on the activity (and cost) of any electrocatalysts. A flexible composite polymer film will allow for electron and ion conduction between the photoanode and photocathode while simultaneously preventing mixing of the gaseous products. Separate polymeric materials will be used to make electrical contact between the anode and cathode, and also to provide structural support. Interspersed patches of an ion conducting polymer will maintain charge balance between the two half-cells.

Nate, George L. Argyros Professor of Chemistry, has been on the faculty at Caltech since 1988 and has served as Professor since 1991. He has also served as Principal Investigator of the Beckman Institute Molecular Materials Resource Center at Caltech since 1992. He was on the faculty at Stanford, as Assistant Professor from 1981 to 1985, and as tenured Associate Professor from 1986 to 1988. Nate received his Ph. D. in Chemistry from the MIT.

Nate has been an Alfred P. Sloan Fellow, a Camille and Henry Dreyfus Teacher-Scholar, and a Presidential Young Investigator. He received the Fresenius Award in 1990, the ACS Award in Pure Chemistry in 1991, the Orton Memorial Lecture award in 2003, the Princeton Environmental Award in 2003, the Michael Faraday Medal of the Royal Society of Electrochemistry in 2008, and was elected to the National Academy of Inventors’ 2017 class of fellows. He is currently Editor-in-Chief of Energy & Environmental Science. He has published over 500 papers and has supervised approximately 100 graduate students and postdoctoral associates.

His research interests include artificial photosynthesis and electronic noses. Nate has been active in the solar fuels, solar chemical field, for over 40 years. Details of these research topics focus on light-induced electron transfer reactions, both at surfaces and in transition metal complexes, surface chemistry and photochemistry of semiconductor/liquid interfaces, novel uses of conducting organic polymers and polymer/conductor composites, and development of sensor arrays that use pattern recognition algorithms to identify odorants, mimicking the mammalian olfaction process.

Webinar - Negotiating your Net Worth: Tools, Techniques and Tactics to Getting the Salary you Deserve

Location: Webinar

Description:

If you miss out on negotiating your starting salary by only 7% in your first year of work, you may lose $500K-$1.2 million in salary over 30 years of employment. Change that equation by attending this webinar. You will learn what general negotiation tactics and techniques work and how to use these tools effectively to negotiate your compensation. Learn how to overcome your fears around negotiating and empower yourself to be the best negotiator possible. The first part of the webinar will begin with a general discussion of negotiations (50 minutes). The second part of the webinar (30 minutes) will specifically address negotiation strategies for women and discuss how to optimize communication styles in a business situation. Come learn and earn what you are worth!
