Summary of the Symposium on Data Analytics for Advanced Manufacturing

April 13, 2017
Author(s)
Anantha Narayanan Narayanan, Ronay Ak, Yung-Tsun Lee, Rumi Ghosh, Sudarsan Rachuri
The Symposium on Data Analytics for Advanced Manufacturing was held in conjunction with the 2016 IEEE International Conference on Big Data in Washington D.C. on December 6-7, 2016. The Symposium's goal was to address manufacturing industries' issues, needs

Electroshock Weapon Measurements

April 12, 2017
Author(s)
Nicholas G. Paulter Jr., David M. Jenkins, Norimitsu Ichikawa
Electroshock weapons (ESWs) are a commonly used tool in the escalation of force arsenal for law enforcement and the military around the world. ESWs function by providing a high-voltage low-current electrical shock that, when discharged into a live

Infrared and visible laser spectroscopy for highly-charged Ni-like ions

April 12, 2017
Author(s)
Yuri Ralchenko
Application of visible or infrared (IR) lasers for spectroscopy of highly-charged ions (HCI) has not been particularly extensive so far due to a mismatch in typical energies. We show here that the energy difference between the two lowest levels within the

Nanoscale Imaging and Spectroscopy of Band Gap and defects in Polycrystalline Photovoltaic Devices

April 12, 2017
Author(s)
Yohan Yoon, Jungseok Chae, Aaron M. Katzenmeyer, Heayoung Yoon, Joshua D. Schumacher, Sang M. An, Andrea Centrone, Nikolai B. Zhitenev
Improving the power conversion efficiency of photovoltaic (PV) devices is challenging because the generation, separation and collection of electron-hole pairs in PV devices is strongly dependent on details of the nanoscale chemical composition and defects

Broadband parametric amplifiers based on nonlinear kinetic inductance artificial transmission lines

April 11, 2017
Author(s)
Jiansong Gao, Saptarshi Chaudhuri, Dale Li, Kent D. Irwin, Clint Bockstiegel, Weijie Guo, Xiangliang Liu, Johannes Hubmayr
We present broadband parametric amplifiers based on the kinetic inductance of superconducting NbTiN thin films and an artificial (lumped-element) transmission line architecture. We demonstrate two amplifier designs implementing two different phase matching

Dielectric Characterization of Confined Water in Chiral Cellulose Nanocrystal Films

April 10, 2017
Author(s)
Bharath N. Natarajan, Caglar Emiroglu, Jan Obrzut, Douglas M. Fox, Beatriz Pazmino, Jack F. Douglas, Jeffrey W. Gilman
A known deterrent to a large scale development and use of cellulose nanocrystals (CNCs) is their affinity for moisture, which has a profound effect on dispersion, wetting, interfacial adhesion, matrix crystallization and water uptake. To quantify the

Standardized Measurements of Collection Efficiency from Wipe-Sampling of Trace Explosives

April 10, 2017
Author(s)
Jennifer R. Verkouteren, Jeffrey A. Lawrence, Matthew E. Staymates, Edward R. Sisco
One of the limiting steps to detecting traces of explosives at screening venues is effective collection of the sample. Wipe-sampling is the most common procedure for collecting traces of explosives, and standardized measurements of collection efficiency

BC8 Silicon (Si-III) is a narrow-gap semiconductor

April 7, 2017
Author(s)
Haidong Zhang, Hanyu Liu, Kaya Wei, Oleksandr Kurakevych, Zhenxian Liu, Yann Godec, Joshua Martin, Michael Guerrette, George S. Nolas, Timothy A. Strobel
Large-volume, phase-pure synthesis of BC8 silicon (Ia3 ̅, cI16) has enabled bulk measurements of optical, electronic and thermal properties. Unlike previous reports that conclude BC8-Si is semimetallic, we demonstrate that this phase is a direct band gap

Combining model-based measurement results of critical dimensions from multiple tools

April 7, 2017
Author(s)
Nien F. Zhang, Bryan M. Barnes, Hui Zhou, Mark Alexander Henn, Richard M. Silver
Model-based measurement techniques use experimental data and simulations of the underlying physics to extract quantitative estimates of the measurands of a specimen based upon a parametric model of that specimen. The uncertainties of these estimates are

Light-stimulated Permanent Shape Reconfiguration in Crosslinked Polymer Microparticles

April 7, 2017
Author(s)
Lewis M. Cox, Xiaohao Sun, Chen Wang, Nancy Sowan, Jason Killgore, Rong Long, Hengan Wu, Christopher N. Bowman, Yifu Ding
Covalent adaptable networks (CANs) are cross-linked polymer networks capable reconfiguring their network topology, enabling stress relaxation and shape changing behaviors. Reversible addition-fragmentation chain transfer (RAFT) is one specific mechanism by

Qubit gates using hyperbolic secant pulses

April 7, 2017
Author(s)
Hsiang S. Ku, Junling Long, Xian Wu, Mustafa Bal, Russell Lake, Edwin Barnes, Sophia Economou, David P. Pappas
It has been known since the early days of quantum mechanics that hyperbolic secant pulses possess the unique property that they can perform cyclic evolution on two-level quantum systems independently of the pulse detuning. More recently, it was realized

The synthesis of high-purity Na 2B 12F 12 and the crystal structures of Na 2(B 12F 12) (5 K neutron powder diffraction (NPD)), Na 2(H 2O) 4(B 12F 12) (120 K single-crystal X-ray diffraction (SC-XRD), Na 2(B 12Cl 12) (5 K and 295 K NPD), and Na 2(H 2O) 6(B

Hyperfine-mediated electric quadrupole shifts in Al+ and In+ ion clocks

April 6, 2017
Author(s)
Kyle P. Beloy, David R. Leibrandt, Wayne M. Itano
We evaluate the electric quadrupole moments of the 1S0 and 3P0 clock states of 27Al+ and 115In+. To capture all dominant contributions, our analysis extends through third order of perturbation theory and includes hyperfine coupling of the electrons to both
