Characterization of Interfacial Structure in Polymer-Fullerene Bulk Heterojunctions via 13C {2H} Rotational Echo Double Resonance NMR

July 13, 2018
Author(s)
Ryan C. Nieuwendaal, Dean M. DeLongchamp, Martin Heeney, Jan Hummelen, Chad R. Snyder, Ronald L. Jones, Sebastian Engmann, Lee J. Richter, Zhuping Fei, Alex Sieval
We introduce a new application of solid state NMR measurements towards characterizing the donor-acceptor interfaces within bulk heterojunction (BHJ) films. Rotational echo double resonance (REDOR) is used to measure dipolar couplings between 13C nuclei on

Probing the Structure, Composition and Spatial Distribution of Ligands on Gold Nanorods

August 20, 2015
Author(s)
Michael J. A. Hore, Xingchen Ye, Jamie Ford, Yuzhi Gao, Jiayang Fei, Qiong Wu, Stuart J. Rowan, Russell J. Composto, Christopher B. Murray, Boualem Hammouda
The structure and size of ligands attached to the surfaces of gold nanorods, such as adsorbed surfactants or grafted polymers, are important considerations that facilitate the use of such nanoparticles in the human body, in advanced materials for energy

Robust Two-Qubit Geometric Phase Gates using Amplitude and Frequency Ramping

November 18, 2025
Author(s)
Christina Bowers, Deviprasath Palani, John Barta, Tyler Guglielmo, Stephen Libby, Dietrich Leibfried, Daniel Slichter
We demonstrate a method for generating entanglement between trapped atomic ions based on adiabatically ramped state-dependent forces. By ramping both the amplitude of the state-dependent force and the motional mode frequencies, we realize an entangling

Optical Atomic Clocks

December 1, 2013
Author(s)
Christopher W. Oates, N Poli, P. Gill, G.M. Tino
In the last ten years extraordinary results in time and frequency metrology have been demonstrated. Frequency stabilization techniques for continuous wave lasers and femto-second optical frequency combs have enabled a rapid development of frequency

Anharmonic Phonons and Magnons in BiFeO 3

February 13, 2012
Author(s)
O. Delaire, M. B. Stone, J. Ma, A. Huq, D. Gout, Craig Brown, K. F. Wang, Z. F. Ren
The phonon density of states (DOS) and magnetic excitation spectrum of polycrystalline BiFeO 3 were measured for temperatures 200 less than or equal to}Τ less than or equal to} 750K, using inelastic neutron scattering (INS). Our results indicate that the
