Trapped Highly Charged Ion Plasmas

January 1, 2002
Author(s)
E Takacs, John D. Gillaspy
Electron beam Ion Trap (EBIT) devices are reviewed with special attention to applications in highly charged ion plasma research. EBIT properties are presented based on information extracted from a variety of experiments presented in the literature. Topics

Emergent Electric Field Control of Phase Transformation in Oxide Superlattices

February 1, 2020
Author(s)
Di Yi, Yujia Wang, Olaf M. J. van t'Erve, Liubin Xu, Hongtao Yuan, Michael J. Veit, Purnima P. Balakrishnan, Yongseong Choi, Alpha T. N'Diaye, Padraic Shafer, E. Arenholz, Alexander Grutter, Haixuan Xu, Pu Yu, Berend T. Jonker, Yuri Suzuki
Electric fields have been shown to transform materials with respect to their structure and properties, thus enabling many applications ranging from batteries to spintronics. Recently electrolytic gating, which can generate large electric fields and voltage

Development of a new UHV/XHV pressure standard (Cold Atom Vacuum Standard)

November 10, 2017
Author(s)
Julia Scherschligt, James A. Fedchak, Daniel Barker, Stephen Eckel, Nikolai Klimov, Constantinos Makrides, Eite Tiesinga
The National Institute of Standards and Technology has recently begun a program to develop a primary pressure standard that is based on ultra-cold atoms, covering a pressure range of 1 × 10-6 Pa to 1 × 10-10 Pa and possibly lower. These pressures

Low-Temperature Rotational Tunneling of Tetrahydroborate Anions in Lithium Benzimidazolate-Borohydride Li 2 (blm)BH 4

August 7, 2019
Author(s)
Alexander V. Skripov, Mirjana NMN Dimitrievska, Olga A. Babanova, R. V. Skoryunov, Alexei V. Soloninin, Fabrice Morelle, Y. Filinchuk, Antonio Faraone, Hui Wu, Wei Zhou, Terrence J. Udovic
To investigate the dynamical properties of the novel hybrid compound, lithium benzimidazolate-borohydride Li 2(bIm)BH 4 (where bIm denotes a benzimidazolate anion, C 7N 2H 5u-^), we have used a set of complementary techniques: neutron powder diffraction

Structural Insights into DNA-Stabilized Silver Clusters

May 10, 2019
Author(s)
Danielle Schultz, Robert G. Brinson, Fahriye N. Sari, Jeffrey Fagan, Christina Bergonzo, Nancy Lin, Joy Dunkers
The structure and dynamics of Ag complexes derived from single stranded DNA (ssDNA) is less understood than their double stranded (dsDNA) counterparts despite their great promise as fluorescent biological probes and sensors. In this work, we seek new

Color-map recommendation for MR relaxometry maps

October 16, 2024
Author(s)
Miha Fuderer, Fabio Crameri, Nandita deSouza, Bettina Baessler, Vikas Gulani, Meiyun Wang, Ruud de Boer, Matt Cashmore, Wolter de Graaf, Kathryn Keenan, Dan Ma, Carolin Pirkl, Nico Sollmann, Sebastian Weingartner, Stefano Mandija, Xavier Golay

Low-field MRI: A report on the 2022 ISMRM workshop

June 22, 2023
Author(s)
Adrienne Campbell-Washburn, Katy Keenan, Peng Hu, John Mugler, Krishna Nayak, Andrew Webb, Johnes Obungoloch, Kevin Sheth, Jurgen Hennig, Matthew Rosen, Najat Salameh, Daniel Sodickson, Joel Stein, Jose Marques, Orlando Simonetti

Tribological Performance of Head-Disk Interface Due to Nanoasperity Impacts

October 12, 2021
Author(s)
Tze J. Chuang, Stephen M. Hsu
During the track accessing mode ofa hard disk drive, theflying height of the slider over thedisk surface becomes smaller and smaller as the demand in data storage density increases. As aresult, the propensity of glide avalanche is bound to increase when

Selective spin inversion in solution by magic field cross polarization

November 1, 2019
Author(s)
Joel Tolman, Luke Arbogast
A pulsed element is proposed allowing the selective inversion of a single 1H nucleus, without regard to the presence of other degenerate 1H nuclei, provided that it is coupled to a heteronuclear spin with adequate chemical shift resolution in a 2D

Integration of a versatile bridge concept in a 34 GHz pulsed/CW EPR spectrometer

March 1, 2018
Author(s)
Alan H. Band, Matthew P. Donohue, Boris Epel, Shraeya Madhu, Veronika Szalai
We present a 34 GHz continuous wave (CW)/pulsed electron paramagnetic resonance (EPR) spectrometer capable of pulse-shaping that is based on a novel microwave bridge design. The bridge radio frequency (RF)-in/RF-out design (500 MHz to 1 GHz input/output

Accuracy, repeatability and interplatform reproducibility measurements of T 1 quantification methods used for DCE-MRI: results from a multicenter phantom study.

August 16, 2017
Author(s)
Octavia Bane, Stefanie J. Hectors, Mathilde Wagner, Lori L. Arlinghaus, Madhava P. Aryal, Yue Cao, Thomas L. Chenevert, Fiona Fennessy, Wei Huang, Nola M. Hylton, Jayashree Kalpathy-Cramer, Katy Keenan, Dariya I. Malyarenko, Robert V. Mulkern, David C. Newitt, Stephen E. Russek, Karl Stupic, Michael A. Boss
Purpose: To determine the in vitro accuracy, test-retest repeatability, and interplatform reproducibility of T 1 quantification protocols used for dynamic contrast-enhanced MRI at 1.5 and 3 T. Methods: A T 1 phantom with 14 samples was imaged at eight
