Shippert Co-author of Paper Featured in Nature

Work describes first observations of surface radiative forcing by carbon dioxide using ARM data

February 2015
For his contribution to research recently showcased in a paper published in Nature, Tim Shippert, a scientist with the ARM Data Integration team in PNNL’s ACMD Division, ran six model years of ARM data to evaluate reviewers’ questions about specific calculations. The resulting work provided evidence of the first observed influence of atmospheric carbon dioxide at the Earth’s surface and helps confirm that climate models are accurately representing carbon dioxide’s impacts to climate.

Transformations: The Value of Catalysis, Top Five List from CME's Last Five Years, Catalytic Choreography

February 2015

In the latest edition of the Institute for Integrated Catalysis' Transformations, PNNL scientist Bob Weber provides an overview on the value of catalysis to the economy, society, and scientific research in general. This issue's feature is on the top five things learned in the first five years of the Center for Molecular Electrocatalysis at PNNL. This Energy Frontier Research Center has answered fundamental questions about what makes catalysts work. Transformations also contains the Institute for Integrated Catalysis's (IIC's) latest video, "Catalytic Choreography," catalysis scientist Zdenek Dohnalek (see photo) explains how his team at PNNL discovers how molecules move, break and rejoin on the surface of a catalyst-fundamental knowledge that could be used to design better catalysts to produce renewable energy.
