Impact of Nanoparticles on the Segmental and Swelling Dynamics of Ionomer Nanocomposite Membranes

March 12, 2019
Author(s)
Apoorv Balwani, Antonio Faraone, Eric M. Davis
… vanadium redox flow battery, the marginal improvements in ion selectivity are insufficient for wide-scale … phases of the ionomer, thereby altering the vanadium ion transport via slowdown of fluorocarbon chain dynamics. … from this study have profound implications for controlling ion selectivity in these ionomer nanocomposite membranes. …

Small Particle Growth in Silane Radio-Frequency Discharges

February 1, 2000
Author(s)
M A. Childs, Alan Gallagher
… 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

Dynamical evolution of the 2D/3D interface: a hidden driver behind perovskite solar cell instability

January 3, 2020
Author(s)
Lee J. Richter, Ahmad R. Kirmani, Albertus A. Sutano, Nikita Drigo, Ines G. Benito, Valentine I. Queloz, Kyung T. Cho, Pascal A. Schouwink, Mohammad K. Nazeeruddin, Giulia Grancini, Sanghyun Paek
… in the 3D cage move towards the 2D layer, which acts as an ion scavenger. If structurally stable, the 2D layer physically blocks the ion movement at the interface boosting the device stability. …

Switching Between Giant Positive and Negative Thermal Expansions of a YFe(CN) 6 -Based Prussian Blue Analogue Induced by Guest Species

July 24, 2017
Author(s)
Qilong Gao, Jun Chen, Qiang Sun, Dahu Chang, Qingzhen Huang, Hui Wu, Andrea Sanson, Ruggero Milazzo, He Zhu, Qiang Li, Zhanning Liu, Jinxia Deng, Xianran Xing
The control of thermal expansion of solid compounds is intriguing but remains challenge. In this study, we investigate the effect of guests on the thermal expansion of open-framework structures. It is interesting to observe that the presence of guest ions

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
