The school is one of the largest atmospheric and environmental academic research centers in Britain. Pearce, who came to the Laboratory in 2009, is investigating how minerals and microbes affect technetium and other radionuclides in the soil at a former plutonium production site in southeastern Washington State. ]]>Thu, 19 Nov 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=692Dr. Michael Thackeray at the Pacific Northwest National Laboratory's Frontiers in Materials Sciences Seminar Series. The series features academic, government, and industrial leaders who discuss novel ideas and advancements in science. ]]>Tue, 10 Nov 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=688Results: Whole water molecules form complex shapes around hydroxide ions, simple negatively charged particles, according to a recent study by scientists at Pacific Northwest National Laboratory. The shapes are the result of hydrogen bonds between the ions and the molecules. This research answers the question, debated in scientific circles for more than 70 years, of how hydroxide ions get oriented in water. This work graced the cover of the October 19, 2009, issue of Chemical Physics Letters. ]]>Tue, 03 Nov 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=689Primitive: that's how Dr. John Bargar describes the state of knowledge of the reactivity of biogenic uranite in ground water. Biogenic uranite is a form of uranium, produced by bacteria, that is fairly immobile in groundwater. Bargar discussed his work to turn this primitive knowledge into a sophisticated understanding at Pacific Northwest National Laboratory's Frontiers in Biogeochemistry Seminar Series. The series features scientists who discuss novel ideas and advancements in geochemical research and development. ]]>Sun, 01 Nov 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=684Results: Recently, a trio from Pacific Northwest National Laboratory and Louisiana Tech University showed that strontium ions congregate on water's surface. Their computer simulation and careful calculations finally demonstrated why experiments and conventional wisdom clashed about the behavior of this type of ion, a divalent cation or one with two electrons missing. ]]>Wed, 28 Oct 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=682Results: Uranium's migration through the soil depends on groundwater's chemical composition, according to a recent study by Pacific Northwest National Laboratory. Scientists showed that uranium attached to soil particles and moved slowly when the groundwater was at neutral pH and contained low levels of carbonate ion or dissolved carbon dioxide. Such conditions often occur at riverbanks when the river water rises and mixes with the groundwater. This work appeared in the September 1 issue of Environmental Science & Technology. ]]>Mon, 26 Oct 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=679Science reveals new, important details about a common catalyst: how rafts of chemically reactive platinum form in the catalyst. The new work yields insights into how to improve the industrial catalyst for oil refining, chemicals processing and environmental uses. ]]>Mon, 05 Oct 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=677Wed, 30 Sep 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=673Tue, 29 Sep 2009 00:00:00 GMThttp://www.pnl.gov/science/highlights/highlight.asp?id=671Pacific Northwest National Laboratory.
