THE NEED FOR TRANSFORMATIONAL SCIENCE 1600 Society’s advances are built on scientific discoveries, many of which transformed our under- standing of the world. Many people see science as a selfish pursuit; researchers conduct expen- sive experiments with no application to today’s problems, but this view and new ideas. New materials, new processes, and new questions continue to arise. At the Department of Energy’s Pacific misses the raison d’être for funda- In the late 1600s, Anton van Northwest National Laboratory, our mental science—our prosperity and Leeuwenhoek discovered tiny scientists are pushing the frontiers of security rely on our understanding creatures in plaque.

Researchers at Pacific Northwest National Laboratory designed a novel, cutting-edge light enclosure for a photobioreactor that blocks ambient light while providing red and blue light using energy- efficient LEDs. This photobioreactor is aiding in optimizing hydrogen and biofuel production from photosynthetic microbes. OBTAINING A PREDICTIVE Understanding OF MULTI- CELLULAR SYSTEMS To paraphrase John Donne: no cell is an island. Whether it is a bacterium such as E. coli or part of a plant, animal, or fungi, each cell has a specific role for which it was created. But a cell doesn’t act alone. Cells are part of multi- cellular biological systems—from microbial communitites to humans. The environment, neighboring cells, and other processes all impact a cell’s behavior and function. Limited information is available about how communities of cells and organ- isms respond and adjust to environmental stress or changes as multi-cellular systems. PNNL is developing and applying technologies for measuring biolog- ical, chemical, and physical properties at relative spatial and time scales. We are also developing the computational framework that links this information to cell communities and environmental interfaces. Because of the ever-increasing volume of cell information, today’s instru- ments can’t easily analyze and interpret the data. So, scientists at PNNL are creating first-of-a-kind tools and techniques that can provide high-throughput Integrating experimental data data and quickly analyze these large data sets with unprecedented resolution. from award-winning tools such as the ESI-MS Source & Interface By combining experimental data with theoretical studies and computational with theoretical studies and resources, we are pushing the state of the science and learning how living computational models, biologists systems composed of different types of cells will respond and adjust to change. at Pacific Northwest National By doing so, we can also find ways to understand and predict how cells perform Laboratory are pushing the state in ways that will benefit us by providing new energy sources, cleaning up our of science regarding proteins and environment, influencing carbon sequestration, and impacting human health. other cellular molecules.

UNDERSTANDING AND CONTROLLING CHEMICAL AND PHYSICAL PROCESSES IN COMPLEX ENVIRONMENTS Photosynthesis. Burning coal. Refining oil. For hundreds of years, scientists have examined these and other processes to understand how reactions work in the real world. Understanding is key to controlling. However, much of our knowledge is limited to simpler gas-phase systems. How atoms, molecules, and microbes behave in liquid water and other condensed phases as well as at interfaces pres- ents a host of mysteries. At PNNL, our scientists are solving these mysteries. Working on the small scale. Through new methods and technologies, scientists are learning how atoms, molecules, and ions interact with photons and electrons, and how to make and break chemical bonds. This under- standing is transforming how we view the interaction of minerals, microbes, and other subsurface reactions. Further, understanding reactions from elec- trons to molecules is key to building new materials. At PNNL, scientists are learning to build, atom by atom, materials that control charge transport in sensors, batteries, and fuel cells. Our experts combine experimental, theoretical, and Leading on the world stage. In the United States, China, and other computational approaches to countries, catalyzing reactions efficiently is key to mitigating the impacts of shed light on processes and energy use and manufacturing. In looking to solve near-term issues, scientists reactions, such as the movement at the Laboratory’s Institute for Interfacial Catalysis conduct world-leading of charges through water, in research to convert biomass and coal to cleaner energy sources. Taking a more next-generation fuel cells. fundamental discovery approach, scientists at the newly formed Center for Molecular Electrocatalysis are delving into molecular systems that convert electrical energy into chemical bonds and back again.
