Comparing laser patterning of submicron structures into metal
<p>Within the EU funded project Laser4Surf European researchers are exploring how using laser structuring can alter and improve the properties or performance of metals. This graphic compares the patterning of metal surfaces with the help of Direct Laser Interference or Direct Laser Ablation (DLA) with Laser Induced Periodic Surface Structures (LIPSS).</p>

Raw and processed anomalous diffraction data for crystals of metal-free R2lox soaked with Mn, Fe and Co or Zn
<p>Raw and processed anomalous diffraction data for crystals of metal-free <em>Geobacillus kaustophilus</em> R2-like ligand-binding oxidase (R2lox) soaked with 5 mM each MnCl<sub>2</sub>, (NH<sub>4</sub>)<sub>2</sub>Fe(SO<sub>4</sub>)<sub>2</sub> and CoCl<sub>2</sub> or ZnCl<sub>2</sub>. Data were collected on two crystals each after soaking with Mn, Fe and Co or Mn, Fe and Zn, respectively. For each crystal, one dataset each was collected at the Fe K edge (7162 eV), Mn K edge (6589 eV) and Co K edge (7721 eV) or Zn K edge (9664 eV; X-ray energies corresponding to the theoretical K edge + 50 eV). Data were collected at 100 K on a Pilatus 6M detector at beamline X06SA of the Swiss Light Source (SLS, Villigen, Switzerland) on September 23, 2012, and processed with XDS and XSCALE. All raw and processed diffraction data for each crystal are compressed into one file. </p>
Liquid metal solves maze
<p>These are supplementary videos for the paper ``Liquid Metal Solves Mazes'. The abstract of the paper is below. </p> <p> </p> <p>A room temperature liquid metal is a metal whose melting point is around room temperature. We use liquid metal gallium due to its non-toxicity. A physical maze is a a connected set of Euclidean domains separated by impassable walls. We demonstrate that a maze filled with sodium hydroxide is solved by a gallium droplet when direct current is applied between start and destination loci. During the maze solving the droplet stays compact due to its large surface tension, navigate along lines of the highest electrical current due its high electrical conductivity, and goes around corners of the maze's corridors due to its high flexibility. The droplet maze solver has a long life-time due to negligible vapour of the liquid gallium.</p>

For example, the directory 1.600_0.500_0.900 corresponds to the simulation with log10(M1/Msun)=1.6, M2/M1=0.5 and Porb=0.9 days. Each folder is also a MESA template folder, containing all input files neccesary to reproduce that individual simulation.</p> <p>The file summary_tables.tar.gz contains summarized information for each simulation in ascii format.</p>

Development of Metals Corrosion Maps of Arkansas and Maintenance of Cross-Drains
<p>Corresponding data set for Tran-SET Project No. 18GTASU01. Abstract of the final report is stated below for reference:</p> <p>"Corrosion potential of metallic structures in alluvial soils is governed by chemical and electromagnetic properties of the soils. Geotechnical engineers are generally more concerned about different types of soils and their physical and mechanical properties than the chemical aspects. The main objective of this study is to analyze the geotechnical, electrochemical and electromagnetic properties of soils in Arkansas. Important parameters (e.g., soil resistivity) related to corrosion potential of metal culverts have been predicted through neural network (NN) models. The developed NN models have been trained and verified by using laboratory test results of soil samples collected from Arkansas Department of Transportation (ARDOT), and survey data obtained from the United States Department of Agriculture (USDA) and Arkansas Department of Environmental Quality (ADEQ). Finally, the Geographic Information System (GIS) based corrosion risk maps of three different types of metal pipes have been developed based on the available soil properties, metal properties, and water quality data. The developed maps will help ARDOT engineers to assess corrosion potential of metal pipes prior to the new construction and repair projects and use proper culvert and cross drain materials."</p>
