Dynamics of the Extended and Intermediate Range Order in Model Polymer Electrolyte Poly(Ethylene Oxide) and Lithium Bis(Trifluoromethanesulfonyl)imide

April 17, 2023
Author(s)
Peter Falus, Antonio Faraone, Stephan Forster, Kunlun Hong, Michael Ohl
The dynamics of lithium ions and polymer chains were investigated at the molecular scale in the model polymer electrolyte Poly (Ethylene Oxide) (PEO)/Lithium bis(trifluoromethanesulfonyl)imide as a function of temperature. This system is known to present

Super Charge Separation and High Voltage Phase in Na x MnO 2

December 12, 2018
Author(s)
Xi Chen, Yichao Wang, Kamila Wiaderek, Xiahan Sang, Olaf Borkiewicz, Karena Chapman, James LeBeau, Jeffrey W. Lynn, Xin Li
Na xMnO 2 shows Mnu3+^ and Mn^ 4+ charge separation with charge stripe ordering upon Na de-intercalation at x=5/8, similar to many colossal magnetoresistance materials. We show in this paper that, surprisingly, at lower Na compositions of 5/8 >x less than

Linewidth narrowing and Purcell enhancement in photonic crystal cavities on an Er-doped silicon nitride platform

January 25, 2010
Author(s)
Yiyang Gong, Maria Makarova, Selcuk Yerci, Rui Li, Martin Stevens, Burm Baek, Sae Woo Nam, Robert Hadfield, Sander N. Dorenbos, Val Zwiller, Luca Dal Negro, Jelena Vuckovic
Light emission at 1.54 mm from an Er-doped amorphous silicon nitride layer coupled to photonic crystal resonators at cryogenic and room temperatures and under varying optical pump powers has been studied. The results demonstrate that small mode volume

Room-Temperature Solid-State Nitrogen-Based Magneto-Ionics in CoxMn1-xN Films

… The model and data confirms that the plasma positive ion density greatly exceeds the electron density, and that the average netgative ion mass exceeds the average positive ion mass. …

Nanosilver suppresses growth and induces oxidative damage to DNA in Caenorhabditis elegans

May 2, 2013
Author(s)
Bryant C. Nelson, Bryce J. Marquis, Piper R. Hunt, Katherine M. Tyner, Sean Conklin, Nicholas Olejnik, Robert L. Sprando
The utility of C. elegans as an alternative model to assess nanomaterial toxicity was evaluated using 10 nm silver particles (10nmAg). Endpoints of nanomaterial uptake and localization, larval growth, morphology, and DNA damage were assessed. Orally
