PNNL Highlights for the Office of Basic Energy Sciences (July 2013 – July 2014) PNNL-23552 About the Cover: Long thought to be unresponsive to ultraviolet light, oxygen adatoms actually respond to light. PNNL researchers made this discovery by coating the surface of the catalyst titanium dioxide with krypton reporters. When light strikes the catalyst, the oxygen adatoms become electronically excited and knock the krypton off the surface. PNNL Highlights for the Office of Basic Energy Sciences (July 2013 – July 2014) August 2014 Prepared for the U.S. Department of Energy under Contract DE-AC05-76RL01830 Pacific Northwest National Laboratory Richland, Washington 99352 Summary Pacific Northwest National Laboratory Highlights for the Office of Basic Energy Sciences showcases our fundamental research to understand, predict, and ultimately control matter and energy at the electronic, atomic, and molecular levels to provide the foundations for new energy technologies and to support the U.S. Department of Energy’s missions. The highlights are from July 2013 to July 2014. In addition to reading about outstanding fundamental research that appeared in key scientific publications, you’ll also see invited review articles, where our staff were asked to provide the definitive examination of a topic. The BES leadership highlights showcase our experts’ contributions to the chemical sciences, geosciences, biosciences, and materials sciences. You’ll see new fellows in the Materials Research Society, Royal Society of Chemistry, and other organizations along with awards from professional societies in the United States and abroad. As you leaf through these pages, you will see that Pacific Northwest National Laboratory’s contributions to BES programs are making significant impacts in the basic energy sciences. PNNL is poised to deliver even more important science to the nation in the future. We are pleased to share this limited edition compilation with you. iii Contents Research Highlights

  • Re-Thinking Recognition: Science Prizes for the Modern World
    TALENT Re-thinking recognition: Science prizes for the modern world Introducing our new perspectives series In a world where global challenges and advances in technology bring both uncertainty and new possibilities, the chemical sciences have a critical role to play. But what will that role be? How can we maximise the impact we make across academia, industry, government and education? And what actions should we take to create a stronger, more vibrant culture for research that helps enable new discoveries? Our perspectives series addresses these questions through four lenses: talent, discovery, sustainability and knowledge. Drawing together insights and sharp opinion, our goal is to increase understanding and inform debate – putting the chemical sciences at the heart of the big issues the world is facing. Talent Talent is the lifeblood of the chemical sciences. But how do we inspire, nurture, promote and protect it? Where will we find the chemical scientists of the future? And what action is required to ensure we give everyone the greatest opportunity to make a positive difference? Discovery Chemistry is core to advances across every facet of human life. But where do the greatest opportunities lie? How will technology shape the science we create? And what steps should we take to ensure that curiosity-driven research continues to unlock new opportunities in unexpected ways? Sustainability Our planet faces critical challenges – from plastics polluting the oceans, to the urgent need to find more sustainable resources. But where will new solutions come from? How can we achieve global collaboration to address the big issues? And where can the chemical sciences deliver the biggest impacts? Knowledge Around the world research fuels scientific progress but the way we are sharing new knowledge is changing.

Or that more people die from falling off ONON BOARDBOARD small boats (16 feet and Boating under) than larger ones? Here are some tips for accident-free boating: WITHWITH Safety Rules for Boating: • Be weather wise. Bring a BOATING portable radio to check BOATING weather reports. • Bring extra gear you may need. A flashlight and extra batteries, matches, map, flares, first aid SAFETY kit, sunglasses and sunscreen SAFETY should be kept in a watertight container or pouch. • Tell someone where you’re going, who is with you, and how long you’ll be gone. • Ventilate after fueling. Open the hatches, run the blower, and carefully sniff for gasoline fumes in the fuel and engine areas before starting your engine. • Anchor from the bow, not the stern. Use an anchor line at least five times longer than the water depth. • Know your boat’s capacity. Don’t overload it or put an oversized motor on it. Have fun on the water. Boat safely!

His renewed passion for the form is evident on every page of Just After Sunset. Who but Stephen King would turn a Port-O-San into a slimy birth canal, Just After Sunset: Stories a roadside honky-tonk into a place for endless love? A book salesman with a grievance might pick up a mute hitchhiker, not knowing the silent man in the passenger seat listens altogether too well. Or an exercise routine on a stationary bicycle, begun to reduce bad cholesterol, might take its rider on a captivating--and then terrifying--journey. Set on a remote key in Florida, " The Gingerbread Girl " is a riveting tale featuring a young woman as vulnerable--and resourceful--as Audrey Hepburn's character in Wait Until Dark. In "Ayana," a blind girl works a miracle with a kiss and the touch of her hand. For King, the line between the living and the dead is often blurry, and the seams that hold our reality intact might tear apart at any moment. In one of the longer stories here, "N.

    16th Boron Chemistry Meeting in the Americas June 26 - 30, 2018 at Boston College Program and Abstracts 1 WELCOME It is our distinct pleasure to welcome you to the 16th Boron Chemistry Meeting in the Americas here at Boston College. We hope that you will enjoy the historic city of Boston as well as the four-day program filled with exciting talks and stimulating discussions. Delegates from all over the world (North-, Central-, and South America, Europe, and Asia), and from diverse backgrounds (academia, industry, and government) are coming together at this conference to learn about the latest developments in boron chemistry. Thus, we hope that this gathering will not only promote scientific exchange and collaboration but also provide an opportunity for participants to make new connections and to reconnect with old friends. In organizing the program, the vision we had was to highlight the versatility of the element boron in four specific areas (medicinal chemistry, organic synthesis, materials chemistry, fundamental chemistry). This four-pronged thematic focus is represented by our conference logo with four infinity symbols surrounding the boron and is reflected by the scientific program. One of the highlights of the program will be the poster session on Wednesday evening. This will be a great opportunity to chat about the latest research while enjoying small bites and drinks. Another highlight is the conference banquet, which will take place on Thursday evening at the exquisite State Room with unparalleled views of the city and the Boston waterfront from the 33rd floor in the heart of downtown Boston. During the banquet we will celebrate Prof.
