Mechanistic Insights into the Formation of Porous Carbons from Gelatin

May 1, 2017
Author(s)
A. E. Danks, M. J. Hollamby, Boualem Hammouda, D. C. Fletcher, F. Johnston-Banks, S. E. Rogers, Z. Schnepp
Porous carbons are important for many applications. The biopolymer gelatin provides a simple route to functional carbon foams with77 multimodal porosity. In this paper, small angle neutron scattering is applied alongside other techniques to elucidate the

Effect of Phosphorylation on a Human-like Osteopontin Peptide

April 25, 2017
Author(s)
Samuel Lenton, Marco Grimaldo, Felix Roosen-Runge, Frank Schreiber, Tommy Nylander, Roger Clegg, Carl Holt, Michael Hartlein, Victoria Garcia Sakai, Tilo Seydel, Susana C. Marujo Teixeira
Osteopontin is a disordered phosphoprotein that is expressed in many species and tissues and has a range of distinct functions. A notable property of more highly phosphorylated isoforms of osteopontin is their ability to sequester nanoclusters of calcium

Performance of van der Waals Corrected Functionals for Guest Adsorption in the M 2 (dobdc) Metal-Organic Frameworks

April 24, 2017
Author(s)
Bess Vlaisavljevich, Johanna Huck, Zeric Hulvey, Kyuho Lee, Jarad A. Mason, Jeffrey B. Neaton, Jeffrey R. Long, Craig Brown, Dario Alfe, Angelos Michaelides, Berend Smit
Small molecule binding in metal-organic frameworks (MOFs) can be accurately studied both experimentally and computationally, provided the proper tools are employed. Herein, we compare and contrast properties associated with guest binding with density

Combining Microscopic and Macroscopic Probes to Untangle the Single-Ion Anisotropy and Exchange Energies in an S = 1 Quantum Antiferromagnet

April 20, 2017
Author(s)
Jamie Brambleby, Jamie Lee Manson, Paul A. Goddard, Matthew B. Stone, Roger D. Johnson, Pascal Manuel, Jacquelina A. Villa, Craig Brown, Helen Lu, Shalinee Chikara, Vivien Zapf, Saul H. Lapidus, Rebecca Scatena, Piero Macchi, Yu-Sheng Chen, Lai-Chin Wu, John Singleton
We derive a synergistic approach to determine the spin Hamiltonian and field-temperature phase diagram for polycrystalline samples of S = 1 [Ni(HF 2)(pyz) 2]SbF 6 by exploiting a selected range of experimental techniques. Spatial exchange anisotropy was

Structural Features and Lipid Binding Domain of Tubulin on Biomimetic Mitochondrial Membranes

April 18, 2017
Author(s)
David Paul Hoogerheide, Sergei Y. Noskov, Daniel Jacobs, Lucie Bergdoll, Vitalii Ivanovich Silin, David L. Worcester, Jeff Abramson, Hirsh Nanda, Tatiana K. Rostovtseva, Sergey M. Bezrukov
Amphitropic proteins, the subfamily of peripheral membrane proteins that interact directly with lipid bilayers, comprises members whose function depends on their localization either in the cytosol or at the cellular membranes. Despite the well-established

Ising-Like Antiferromagnetism on the Octahedral Sublattice of a Cobalt-Containing Garnet and the Potential for Quantum Critically

April 14, 2017
Author(s)
Abbey J. Neer, Joanna Milam-Guerrero, Justin E. So, Brent C. Melot, Kate Ross, Zeric Hulvey, Craig Brown, Alexey A. Sokol, David O. Scanlon
In this letter, we report the observation of quasi-one-dimensional magnetism in the garnet CaY 2Co 2Ge 3O 12. Using low-temperature powder neutron diffraction and symmetry analysis, we identify a magnetic structure consisting of chain-like motifs oriented

Comparison of the Coordination of B 12 F 12 ^2-^, B 12 Cl 12 2- , and B 12 H 12 ^2-^ to Na + in the Solid State: Crystal Structures and Thermal Behavior of Na 2 (B 12

The synthesis of high-purity Na 2B 12F 12 and the crystal structures of Na 2(B 12F 12) (5 K neutron powder diffraction (NPD)), Na 2(H 2O) 4(B 12F 12) (120 K single-crystal X-ray diffraction (SC-XRD), Na 2(B 12Cl 12) (5 K and 295 K NPD), and Na 2(H 2O) 6(B

Cubic Lead Perovskite PbMoO 3 with Anomalous Metallic Behavior

April 1, 2017
Author(s)
Hiroshi Takatsu, Olivier Hernandez, Wataru Yoshimune, Carmelo Prestipino, Takafumi Yamamoto, Cedric Tassel, Yoji Kobayashi, Dmitry Batuk, Yuki Shibata, Artem M. Abakumov, Craig Brown, Hiroshi Kageyama
A novel Pb-based perovskite PbMoO 3 is obtained by high-pressure and high-temperature synthesis. This material crystallizes in the Pm3m cubic structure at room temperature, making it distinct from typical Pb-based perovskite oxides with a structural

On the Structure and Dynamics of Water Associated with Single-Supported Zwitterionic and Anionic Membranes

March 28, 2017
Author(s)
A. Miskowiec, Z. N. Buck, F. Y. Hansen, H. Kaiser, H. Taub, Madhu Sudan Tyagi, S. O. Diallo, Eugene Mamontov, K. W. Herwig
We have used high-resolution quasielastic neutron scattering (QENS) to investigate the dynamics of water molecules (time scale of motion 10 u-11-10 -9 s) in proximity to singe-supported bilayers of the zwitterionic lipid DMPC (1,2-dimyristoly-sn-glycero-3

Believable Statements of Uncertainty

February 8, 2017
Author(s)
Richard M. Lindstrom
Nearly fifty years ago, two landmark papers appeared that should have cured the problem of ambiguous uncertainty statements in published data. Eisenhart’s paper in Science called for statistically meaningful numbers, and Currie’s Analytical Chemistry paper

Fast Formation of Low-Defect-Density Tethered Bilayers by Fusion of Multilamellar Vesicles

January 10, 2017
Author(s)
Tadas Ragaliauskas, Mindaugas Mickevicius, Bozena Rakovska, Tadas Penkauskas, Frank Heinrich, Gintaras Valincius
Multilamelar vesicles fuse to molecular-anchor-grafted surfaces yielding low defect density, tethered bilayer membranes. Continuous bilayers are formed within 10 min, while the electrically insulating bilayers with less than 0,1 υmu-1} defect density can
