Science Colloquium Series is a semester long lecture series that offers everyone in the Linfield community the opportunity to learn about science across the traditional science disciplines of biology, chemistry, math, physics, and computer science. *Made possible in part by generous gifts from the Hearst Foundations. Sponsored by Linfield Physics Department.
In Partnership with Program for Liberal Arts and Civic Engagement (PLACE) theme: Air, Water, Earth, and Fire: the ancient elements on a changing planet
*NOTE: Day and location varies as the fall lecture series is partnerned with, and builds to, PLACE events. Refreshments will be available starting 15 min prior to events. Additional information on lectures and events will be added as they are scheduled.

Water - a panel discussion
Linfield faculty representing a wide range of disciplines will discuss water. Whose is it? What is our responsibility? How do we place a value on it? How are these issues discussed from the viewpoints of human health, ecology, economics, social justice, or historical perspective?

"The Electric Porsche Project"
Abstract: The Electric Porsche Project is the application of engineering principles: requirements, modeling, integration, reliability, fabrication, testing, and Newton’s Second Law presented from the perspective of a Systems Engineer. With the advent of commercially available electric cars, does it make sense for a hobbyist to spend nights and weekends converting an internal combustion vehicle to electric drive? Challenges included component selection, integrating a well-balanced system, keeping a high voltage battery pack in a safe operating envelope, thermal management, and staying within budget.

"Fuels from Sunlight"
Abstract:The continued prosperity of human civilization will require replacing fossil fuels with renewable, sustainable, and carbon-free energy sources. More energy hits the earth in the form of sunlight in one hour than civilization uses in one year. The critical science and technology challenge is to develop scalable low-cost methods to convert solar energy into fuel and electricity and to store that energy for times when the sun isn’t shining. One approach is to wire solar cells that generate electricity to electrolysis systems that generate hydrogen and oxygen gas through “water-spitting”. The hydrogen gas can be used in a fuel cell to generate electricity on demand or burned like natural gas, but without CO2 emission. I will discuss our efforts to discover and understand catalysts that enable efficient electrolysis systems without using scarce, precious elements. I will also introduce our study of photoelectrochemical devices – where photovoltaic and electrolysis components are integrated – which in principle allow for low-cost hydrogen gas production in a single step, from water, with only sunlight as the input.
Biography: Boettcher received his B.A. in Chemistry at the University of Oregon in 2003 where he was a Barry M. Goldwater Scholar. He received his Ph.D. in Inorganic Chemistry with Galen Stucky at UC Santa Barbara in 2008 where he was an NSF Graduate Research and UC Chancellor's Fellow. As a Kavli Nanoscience Institute Prize Postdoctoral Scholar, he studied three-dimensional Si electrode structures at the California Institute of Technology working with Nathan Lewis and Harry Atwater. In 2010, he joined the Department of Chemistry at the University of Oregon. His current research is at the intersection of materials science and electrochemistry, with a focus on fundamental aspects of solar energy conversion and storage. In 2011 he was named one of 18 DuPont Young Professors worldwide, in 2014 a Cottrell Scholar, and in 2015 both a Sloan and a Dreyfus awardee.
