Stacking Faults Assist Lithium-Ion Conduction in a Halide-Based Superionic Conductor

April 6, 2022
Author(s)
Elias Sebti, Hayden Evans, Hengning Chen, Peter Richardson, Kelly White, Raynald Giovine, Krishna P. Koirala, Yaobin Xu, Eliovardo Gonzalez-Correa, Chongmin Wang, Craig Brown, Anthony Cheetham, Pieremanuele Canepa, Raphaele Clement
… of stacking faults in the superionic conductor Li 3 YCl 6 and demonstrate a method of controlling its Li+ … connectivity in mechanochemically-synthesized Li 3 YCl 6 . We harness paramagnetic relaxation enhancement to enable 89 Y solid-state NMR, and directly contrast the Y-cation site …

X-ray Computed Tomography Instrument Performance Evaluation, Part III: Sensitivity to Detector Geometry and Rotation Stage Errors at Different Magnifications

September 29, 2021
Author(s)
Prashanth Jaganmohan, Bala Muralikrishnan, Meghan Shilling, Ed Morse
With steadily increasing use in dimensional metrology applications, especially for delicate parts and those with complex internal features, X-ray computed tomography (XCT) has transitioned from a medical imaging tool to an inspection tool in industrial

Genotyping SNPs Using a UV Photocleavable Oligonucleotide in MALDI-TOF MS

March 17, 2005
Author(s)
Peter M. Vallone, K Fahr, M Kostrzewa
Matrix assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF MS) coupled with allele specific primer extension is a proven method for typing single nucleotide polymorphisms (SNPs). A novel modification upon this methodology is the

Observation of Changes in the Atomic and Electronic Structure of Single-Crystal Yba 2 Cu 3 O 6.6 Accompanying Bromination

July 1, 2002
Author(s)
L M. Dieng, A Y. Ignalov, T A. Tyson, Mark Croft, A Dogan, C Y. Kim, Joseph Woicik, J Grow
… recovery of superconductivity in underdoped YBa 2 Cu 3 O 6+y (YBCO) we have performed polarized multiple-edge x-ray … (XAFS) measurements on normal (y nearly equal to} 0.6) and brominated (Br/Cu nearly equal to} 1/30, y nearly … crystals with superconducting transitions at 63K and 89 K, respectively. The brominated sample becomes strongly …

Interfacial Shear Strengths of Dental Resin-Glass Fibers by the Microbond Test

November 1, 2001
Author(s)
Walter G. McDonough, Joseph M. Antonucci, Joy Dunkers
In this study, the feasibility of using the microbond test (MBT) to probe the durability of the bond between a dental resin with differently silanized E-glass fibers was investigated. The E-glass fibers were silanized with equivalent amounts of two types

An improved electronic measurement of the Boltzmann constant by Johnson noise thermometry

July 18, 2017
Author(s)
Jifeng Qu, Samuel Benz, Kevin Coakley, Horst Rogalla, Weston L. Tew, David R. White, Kunli Zhou, Zhenyu Zhou
… constant, k, with a relative uncertainty less than 110-6. These results have been supported by a measurement with a relative uncertainty of 1.910-6 made with dielectric constant gas thermometry. Together, … standard uncertainty of 2.810^-6 and relative offset 0.8910^-6 from the CODATA 2014 recommended value. The most …

Search for a T-odd, P-even Triple Correlation in Neutron Decay

September 14, 2012
Author(s)
Jeffrey S. Nico, T E. Chupp, K P. Coulter, R L. Cooper, S. J. Freeman, B. K. Fujikawa, A. Garcia, Gordon L. Jones, Hans P. Mumm, Alan K. Thompson, C A. Trull, F. E. Wiefeldt, J. F. Wilkerson
… in a blind analysis. Results: We find D=[-0.94 +/- 1.89(stat) +/- 0.97(sys)] x 10^-4. Conclusions: This is the …

Reversible Proton Transfer Dynamics in Bacteriorhodopsin

August 20, 2004
Author(s)
Y. S. Lee, Morris Krauss
Proton transfer in bacteriorhodopsin from the cytoplasm to the extracellular side is initiated from protonated asp96 in the cytoplasmic region towards the deprotonated Schiff base. This occurs in the transition from the photocycle late M state to the N
