Ultrafast Imaging of Fuel and Biofuel Sprays Towards More Efficient and Cleaner Combustion Engines A Collaboration between SC-BES and EERE • • • The hydrodynamic properties of liquid jets, laminar or turbulent, is crucial to the breakup and atomization of fuel to properly prepare the mixture of fuel/air in a combustion cylinder High-speed liquid sprays have been a great challenge in the research field of multiphase hydrodynamics and they have not been understood due to the dearth of experimental and theoretical/simulative methods. The aim of this work is to overcome the difficulties associated with conventional optical methods and to develop a novel method, namely, using ultrafast x-ray imaging, to elucidate this complex multiphase fluid dynamics problem at a fundamental level. The x-ray images of the sprays have revealed, for the first time, the instantaneous spray structure and The liquid breakup of a high-density stream from a fuel dynamics of optically dense sprays with a combined injector as imaged with ultrafast synchrotron x-ray fullfield phase contrast imaging at the APS. unprecedented spatial and temporal resolution. The spray morphology and dynamics will play an important role, well beyond the combustion research, in the emerging fields of microfluidics and nanofluidics that have stimulated great interest in understanding Velocity maps of the jet at t=40, 200 and 400 s complex multiphase flows in confined spatial See: Yujie Wang 1, Xin Liu 2, Kyoung-Su Im 1, Wah-Keat Lee 1, Jin Wang 1, Kamel Fezzaa 1, David L.

Organic Solar Cells Organic photovoltaics show promise for low cost flexible solar cells sunlight Active Layer • For maximum efficiency, the polymer and fullerene (blue and red) must phase separate on 5 -10 nm lengths, but so far this has been poorly characterized. • Small angle x-ray scattering was used to quantify this morphology (plot at far right) including the average distance between polymer/fullerene interfaces & how this depends on solar cell processing • X-ray diffraction was used to characterize polymer/fullerene molecular packing & how this affects solar cell performance • These studies permit rationale optimization of solar cell processing and materials P 3 HT (polymer) PCBM (fullerene) 2 D slice of morphology green = polymer white = fullerene box size = 50 nm BESAC November 5, 2009 23
Natural Photosynthesis New insights into the water splitting mechanism At the heart of the photosynthetic complex in natural systems lies an active site with a cluster of four Mn (red dots) and one Ca (green dot) atoms. Amino acids (ligands) in the surrounding protein are thought to maintain the specific structure necessary for catalytic activity. Glutamate Extended X-ray Absorption Fine Structure (EXAFS) analysis revealed significant structural changes in the mutant that particularly affect the integrity of the Mn-Ca cluster. The histidine residue at site 332 was replaced by a glutamate using site directed mutagenesis. X The structural changes result in a block of the Scycle and loss of water splitting activity, showing that His 332 is essential for proper function. Yachandra, Yano & Sauer,

Seminal Work for 2009 Nobel Prize in Chemistry Conducted at DOE Light Sources Support from US DOE-SC and NIH National Center for Research Re § Ribosome translates the genetic instructions encoded by DNA into chains of amino acids that make up proteins. The ribosome is composed of two subunits: 30 S, which reads the code; and 50 S, which links up the amino acids. The structures of 30 S and 50 S have been crucial to understanding everything from how the ribosome achieves its amazing precision to how different antibiotics bind to the ribosome, knowledge that could help researchers come to grips with the problem of multiresistant bacteria. § Starting in the late 1990 s, Ramakrishnan and Steitz used x-ray crystallography at the NSLS to gather structures of these two ribosome subunits, Ramakrishnan on 30 S and Steitz on 50 S. § Steitz, Ramakrishnan, and Yohath also performed studies at the APS; Although most of the Argonne Nobel-related work was performed at the SBC's beamline at the APS, Steitz and Yonath also used two other APS beamlines: GMCA-CAT and BIOCARS.
