Highly Reversible Zinc Metal Anode for Aqueous Batteries

June 1, 2018
Author(s)
Fei Wang, Oleg Borodin, Tao Gao, Xiulin Fan, Wei Sun, Fudong Han, Antonio Faraone, Joseph Dura, Kang Xu, Chunsheng Wang
Metallic zinc (Zn) has been regarded as an ideal anode material for aqueous batteries, because of its high theoretical capacity (820 mAh/g), low electrochemical potential (-0.762 V vs. SHE), high abundance, low toxicity and intrinsic safety. There has been

Glycerol Hydrogen-Bonding Network Dominates Structure and Collective Dynamics in a Deep Eutectic Solvent

January 25, 2018
Author(s)
Antonio Faraone, Durgesh V. Wagle, Gary A. Baker, E. C. Novak, M. Ohl, D. Reuter, Peter Lunkenheimer, A. Loidl, Eugene Mamontov
The deep eutectic solvent glyceline formed by choline chloride and glycerol in 1:2 molar ratio is much less viscous compared to glycerol, which facilitates its use in many applications where high viscosity is undesirable. Despite the large difference in

Nanoscale Particle Motion in Attractive Polymer Nanocomposites

December 6, 2017
Author(s)
Erkan NMN Senses, Suresh Narayanan, Yimin NMN Mao, Antonio Faraone
Using x-ray photon correlation spectroscopy, we examined slow nanoscale motion of silica nanoparticles individually dispersed in entangled poly (ethylene oxide) melt at particle volume fractions up to 42%. The nanoparticles, therefore, serve as both

Liquid Structure with Nano-Heterogeneity Promotes Cationic Transport in Concentrated Electrolytes

October 10, 2017
Author(s)
Oleg Borodin, Liumin Suo, Mallory Gobet, Xiaoming Ren, Fei Wang, Antonio Faraone, Jing Peng, Marco Olguin, Marshall Schroeder, Michael S. Ding, Eric Gobrogge, Arthur von Wald Cresce, Stephen Munoz, Joseph Dura, Steve Greenbaum, Chunsheng Wang, Kang Xu
Using molecular dynamics simulations, small angle neutron scattering and a variety of spectroscopic techniques, we evaluated the ion solvation and transport behaviors in aqueous electrolytes containing bis(trifluoromethane sulfonyl)imide (LiTFSI). We

Small Particle Driven Chain Disentanglements in Polymer Nanocomposites

April 5, 2017
Author(s)
Erkan NMN Senses, Siyam M. Ansar, Christopher L. Kitchens, Yimin NMN Mao, Suresh Narayanan, Bharath NMN Natarajan, Antonio Faraone
Using neutron spin-echo spectroscopy, X-ray photon correlation spectroscopy and bulk rheology, we studied the effect of particle size on the single chain dynamics, particle mobility, and bulk viscosity in athermal polyethylene oxide-gold nanoparticle

Hydrogen Diffusion in Bulk and Nanocrystalline Palladium: A Quasielastic Neutron Scattering Study

August 29, 2016
Author(s)
Maiko Kofu, Naoki Hashimoto, Hiroshi Akiba, Hirokazu Kobayashi, Hiroshi Kitagawa, Hiroshi Kitagawa, Madhu Sudan Tyagi, Antonio Faraone, John R. Copley, Wiebke Lohstroh, Osamu Yamamuro
The diffusion dynamics of hydrogen in bulk and Nanocrystalline palladium has been examined using quasielastic neutron scattering (QENS). With respect to bulk PdH 0.73, two relaxation processes were found. For both processes, the variation of the relaxation

Structure and Dynamics of Interacting Nanoparticles in Semidilute Polymer Solutions

August 17, 2016
Author(s)
Ryan Poling-Skutvik, Katrina Irene S. Mongcopa, Antonio Faraone, Suresh Narayanan, Jacinta C. Conrad, Ramanan Krishnamoorti
We investigate the structure and dynamics of silica nanoparticles and polymer chains in semidilute solutions of high molecular weight polystyrene in 2-butanone to determine the effect of long range interparticle interactions on the coupling between
