After serving as the Editor-in-Chief for the past three years, I am very pleased to turn over the editorial torch to Dr. Yi Qian who served as the Associate Editor-in Chief during this time. Dr. Qian has been a long-time IEEE volunteer and has all the

SEIRAS Study of Chloride Mediated Polyether Adsorption on Cu

August 31, 2018
Author(s)
Thomas P. Moffat, Daniel Josell, Lee J. Richter
Surface enhanced infrared absorption spectroscopy (SEIRAS) was used to examine the co- adsorption of a selection of polyethers with Cl- under conditions relevant to superconformal Cu electrodeposition in CuSO4-H2SO4 electrolytes. In 0.1 mol/L H2SO4 a

Comment on "Innovative scattering analysis shows that hydrophobic disordered proteins are expanded in water"

August 30, 2018
Author(s)
Robert Best, Alessandro Borgia, Wenwei Zheng, Karin Buholzer, Madeleine Borgia, Hagen Hofmann, Daniel Nettels, Klaus Gast, Alexander Grishaev, Benjamin Schuler
The degree of compaction inferred from SAXS experiments by Riback et al. for unfolded proteins in water versus chemical denaturant is highly consistent with the results from FRET experiments. There is thus no "contradiction" between the two methods, nor

Density and Speed of Sound Measurements of Surrogate Diesel Fuels

August 30, 2018
Author(s)
Tara Fortin
The densities and speeds of sound of four surrogate diesel fuels of varying compositional accuracy were measured at atmospheric pressure over the combined temperature range 278.15 K to 343.15 K. Measurement results for the surrogate fuels were compared to

Kinetic Separation of Propylene over Propane in a Microporous Metal-Organic Framework

August 30, 2018
Author(s)
Libo Li, Xiaoqing NMN Wang, Wei Zhou, Litao Jia, Banglin Chen
Propylene (C 3H 6)/propane (C 3H 8) separation is one of the most challenging as well as most energy-intensive separation processes in the petrochemical industry. Herein we report a microporous metal-organic framework ELM-12 with appropriate channels where

Certification of Standard Reference Material 2365 BK Virus DNA Quantitative Standard

August 29, 2018
Author(s)
Megan H. Cleveland, Natalia Farkas, Kevin M. Kiesler, Blaza Toman, Peter M. Vallone
Standard Reference Material (SRM) 2365 is intended for use in the value assignment of BK virus deoxyribonucleic acid (DNA) to BK DNA controls and standards. A unit of SRM 2365 consists of a well characterized, linearized plasmid, containing BK virus DNA

Topological Transitions Induced by Antiferromagnetism in a Thin-Film Topological Insulator

August 29, 2018
Author(s)
Qing Lin He, Gen Yin, Luyan Yu, Alexander Grutter, Lei Pan, Chui-Zhen Chen, Xiaoyu Che, Guoqiang Yu, Bin Zhang, Qiming Shao, Alexander L. Stern, Brian Casas, Jing Xia, Xiaodong Han, Brian Kirby, Roger K. Lake, K. T. Law, Kang L. Wang
Ferromagnetism in topological insulators (TIs) opens a topologically non-trivial exchange band gap, providing an exciting platform for manipulating the topological order through external magnetic field. Here, we experimentally show that the surface of an

High-speed alignment optimization of digital optical phase conjugation systems based on autocovariance analysis in conjunction with orthonormal rectangular polynomials

August 28, 2018
Author(s)
Ashton S. Hemphill, Yuecheng Shen, Jeeseong C. Hwang, Lihong V. Wang
Digital optical phase conjugation (DOPC) enables many optical applications by permitting focusing of light through scattering media. However, DOPC systems require precise alignment of all optical components, particularly of the spatial light modulator (SLM

Lamellar and bundled domain rotations in barium titanate

August 27, 2018
Author(s)
Jane A. Howell, Mark D. Vaudin, Lawrence Henry Friedman, Robert F. Cook
Cross-correlation of electron backscatter diffraction patterns has been used to generate rotation maps of single crystals of tetragonal barium titanate (BaTiO3) containing multiple lamellae and bundles of  90 domains. Rotation measurement angular

Part-per-million quantization and current-induced breakdown of the quantum anomalous Hall effect

August 27, 2018
Author(s)
Eli J. Fox, Ilan T. Rosen, Yanfei Yang, George R. Jones Jr., Randolph Elmquist, Xufeng Kou, Lei Pan, Kang L. Wang, D. Goldhaber-Gordon
In the quantum anomalous Hall effect, quantized Hall resistance and vanishing longitudinal resistivity are predicted to result from the presence of dissipationless, chiral edge states and an insulating two-dimensional bulk, without requiring an external

Tunable mid-infrared generation via wide-band four-wave mixing in silicon nitride waveguides

August 27, 2018
Author(s)
Abijith S. Kowligy, Daniel D. Hickstein, Alexander Lind, David Carlson, Henry R. Timmers, Nima Nader, Daniel Maser, Daron Westly, Kartik Srinivasan, Scott Papp, Scott Diddams
We demonstrate wide-band frequency down-conversion to the mid-infrared (MIR) using four-wave mixing (FWM) of near-infrared (NIR) femtosecond-duration pulses from an Er:fiber laser, corresponding to 100 THz spectral translation. Photonic-chip-based silicon

Development and Applications of a Fiber-Coupled Atom-Based Electric Field Probe

August 26, 2018
Author(s)
Christopher L. Holloway, Matt Simons, Josh Gordon
We are developing a fundamentally new atom-based approach for electric (E) field measurements. This new approach will lead to a self-calibrated, SI traceable, E-field measurement, and has the capability to perform measurements on a fine spatial resolution

High-resolution near-field imaging and far-fieldantenna measurements with atomic sensors

August 26, 2018
Author(s)
Christopher L. Holloway, Matt Simons, Dave Anderson, Georg Raithel
—Measurements of radio-frequency (RF) electric fields using atomic sensors based on quantum-optical spectroscopy of Rydberg states in vapors has garnered significant interest in recent years for the establishment of atomic standards for RF electric fields

Precipitous change of the irreversible strain limit with heat-treatment temperature in Nb3Sn wires made by the restacked-rod process
