Blanka Halamoda-Kenzaoui, Simon Baconnier, Thierry Bastogne, Didier Bazile, Patrick Boisseau, Gerrit Borchard, Sven E. Borgos, Luigi Calzolai, Karin Cederbrant, Gabriella di Felice, Tiziana Di Francesco, Marina Dobrovolskaia, Rog?rio Gaspar, Bel?n Gracia, Vincent A. Hackley, Lada Leyens, Neill Liptrott, Margriet Park, Anil Patri, Gert Roebben, Matthias Roesslein, Ren? Th?rmer, Patricia Urb?n L?pez, Val?rie Zuang, Susanne Bremer-Hoffmann
The workshop "Bridging communities in the field of nanomedicine" was hosted by the European Commission Joint Research Centre on 27-28 September 2017. It gathered experts from regulatory bodies, research institutions and industry to discuss the main

Fragmentation stimulates soil respiration in temperate forests

April 30, 2019
Author(s)
Ian Smith, Lucy Hutyra, Andrew Reinmann, jonathan thompson, David Allen
Forest fragmentation impacts carbon uptake and storage, however, the magnitude and direction of fragmentation impacts on soil respiration remain poorly characterized. We quantify soil respiration rates along edge-to-interior transects in two temperate

Large-Signal-Network-Analyzer Phase Calibration on an Arbitrary Grid

April 30, 2019
Author(s)
Aric Sanders, Dylan Williams, Joshua Kast, Kate Remley, Rob Horansky
We have developed a method for improving the synchronization of large-signal network analyzers and transferring "cross-frequency" phase calibrations from a calibrated sampling oscilloscope to the large-signal vector network analyzer on an arbitrary

Magnetic Order Effects on the Electronic Structure of KMMnSd2^ (M=Cu,Li) with the ThCr 2 Si 2 -Type Structure

April 30, 2019
Author(s)
Austin Virtue, Xiuquan Zhou, Brandon Wilfong, Jeffrey W. Lynn, Keith Taddei, Peter Zavalij, Limin Wang, Efrain E. Rodriguez
We propose three magnetic structures for KCuMnS^26 with the ThCr 2Si 2-type structure. Powder samples of KCuMnS 2 and KLiMnS 2 were prepared for structural studies and magnetization measurements. In both compounds, the Mn 2+ site is alloyed by either Cu +

X-ray computed tomography instrument performance evaluation: Detecting geometry errors using a calibrated artifact

April 30, 2019
Author(s)
Balasubramanian Muralikrishnan, Katharine M. Shilling, Steven D. Phillips, Wei Ren, Vincent D. Lee, Felix H. Kim, Gabriel Alberts, Valentina Aloisi
X-ray computed tomography (XCT) is uniquely suitable for non-destructive dimensional metrology of delicate or internal features generated from the additive manufacturing process. While XCT has long been used in medical imaging, it has only been used for

Application of the group contribution volume translated Peng-Robinson equation of state to new commercial refrigerant mixtures

April 29, 2019
Author(s)
Ian H. Bell, Jonathan Welliquet, Maria Mondejar, Sylvain Quoilin, Ala Bazyleva, Frederik Haglind
The search of new refrigerants complying with the most recent environmental regulations must be supported by the availability of simple and reliable models for the prediction of their thermophysical behavior, both as pure substances and as mixtures. Cubic

Assessing Fire-blocking Effectiveness of Barrier Fabrics in the Cone Calorimeter

April 29, 2019
Author(s)
Shonali Nazare, William M. Pitts, Mauro Zammarano, John R. Shields, Elizabeth Knowlton, Benito De Leon
Cone calorimetric experiments have been conducted on bare flexible polyurethane foam (FPUF) samples as well as FPUF covered with a variety of fire-blocking barrier fabrics (BFs) in order to characterize and rank BF effectiveness for improving the

Nanomechanics of cellulose deformation reveal molecular defects that facilitate natural deconstruction

April 29, 2019
Author(s)
Peter Ciesielski, Ryan Wagner, Vivek Bharadwaj, Jason Killgore, Ashutosh Mittal, Gregg Beckham, Stephen Decker, Michael Himmel, Michael Crowley
Technologies surrounding utilization and processing of cellulosic materials have been important to human society for millennia. As with many materials, achieving a molecular-level understanding of the formation, characteristics, and functionality of

A Synchrotron X-ray Micro-Spectroscopy Study of the Explosive Melt Glass Derived From the Trinity Nuclear Test

April 28, 2019
Author(s)
Bruce Ravel, Daniel E. Crean, Daniel J. Bailey, M. C. Stennett, Claire L. Corkhill, Ryan Tappero, N. C. Hyatt
Trinitite, the explosive melt glass derived from the Trinity nuclear test, is of interest as a model material for nuclear forensics investigation. However, there remains uncertainty as to the mechanism of trinitite formation. In this study, new insight is

Protocols for tensile testing flexible unidirectional composite laminates

April 27, 2019
Author(s)
Amy E. Engelbrecht-Wiggans, Ajay Krishnamurthy, Faraz A. Burni, William A. Osborn, Amanda L. Forster
Many body armor designs incorporate unidirectional (UD) laminates. UD laminates are constructed of thin layers of high performance yarns where the yarns in each layer are oriented parallel to each other and held in place using binder resins and thin

Chemistry from 3D-printed objects

April 26, 2019
Author(s)
Matthew R. Hartings, Zeeshan Ahmed
3D printing technology has started to take hold as an enabling tool for scientific advancement. Born from the marriage of computer-aided design and additive manufacturing, 3D printing was originally intended to generate prototypes for inspection before

Evaluation of a lateral flow immunoassay for the detection of the synthetic opioid fentanyl

April 26, 2019
Author(s)
Edward Sisco, Daniel J. Angelini, Tracey D. Briggs, Michele N. Maughan, Michael G. Feasel, Jennifer W. Sekowski
In the United States in 2016, 64,000 overdose deaths were reported to be associated with the abuse of opioids, including prescription painkillers (e.g. oxycodone), opiates (e.g. heroin), or synthetic opioids (e.g. fentanyl). The recent spike in the
