UV-assisted room-temperature chemiresistive NO2 sensor based on TiO2 thin film

Author(s)
Ting Xie, Nichole Sullivan, Kristen L. Steffens, Baomei Wen, Guannan Liu, Ratan K. Debnath, Albert Davydov, Romel D. Gomez, Abhishek Motayed
TiO2 thin film based, chemiresistive sensors for NO2 gas which operate at room temperature under ultraviolet (UV) illumination have been demonstrated in this...

Tip characterization method using multi-feature characterizer for CD-AFM

Author(s)
Ndubuisi G. Orji, Hiroshi Itoh, Chumei Wang, Ronald G. Dixson, Sebastian Schmidt, Bernd Irmer, Peter S. Walecki
In atomic force microscopy (AFM) metrology, the tip is a key source of uncertainty. Images taken with an AFM show a change in feature width and shape that...

High-efficiency superconducting nanowire single-photon detectors fabricated from MoSi thin-films

Author(s)
Varun B. Verma, Boris Korzh, Felix Bussieres, Robert D. Horansky, Shellee D. Dyer, Adriana E. Lita, Igor Vayshenker, Francesco Marsili, Matthew D. Shaw, Hugo Zbinden, Richard P. Mirin, Sae Woo Nam
We report on MoSi SNSPDs which achieved high system detection efficiency (87.1 ± 0.5% at 1542 nm) at 0.7 K and we demonstrate that these detectors can also be...

Intrinsic Spin Torque Without Spin-Orbit Coupling

Author(s)
Kyoung-Whan Kim, Kyung-Jin Lee, Hyun-Woo Lee, Mark D. Stiles
For non-uniform magnetic textures, we derive an intrinsic contribution to the non-adiabatic spin torque that may be the dominant contribution. It differs from...

Third-Party Software's Trust Quagmire

Author(s)
Jeffrey M. Voas, George Hurlburt
Integrating software developed by third-party organizations into a larger system raises concerns about the software's quality, origin, functionality, security...

Managing Risk in a Cloud Ecosystem

Author(s)
Michaela Iorga, Anil Karmel
The article focuses on the tier 3 security risks related to the operation and use of cloud-based information systems. To prevent and mitigate any threats...

New perspective on glycoside hydrolase binding to lignin from pretreated corn stover

Author(s)
John M. Yarbrough, Ashutosh Mittal, Elisabeth Mansfield, Larry Taylor, Sarah Hobdey, Deanne W. Sammond, Yannick J. Bomble, Michael F. Crowley, Stephen R. Decker, Michael E. Himmel, Todd B. Vinzant
Non-specific binding of cellulases to lignin has been implicated as a major factor in the loss of cellulase activity during biomass conversion to sugars. It is...

Multi-element logic gates for trapped-ion qubits

Author(s)
Ting Rei Tan, John P. Gaebler, Yiheng Lin, Yong Wan, Ryan S. Bowler, Dietrich G. Leibfried, David J. Wineland
Precision control over hybrid physical systems at the quantum level is of general importance in physics. For trapped-ions, a hybrid system formed of different...

A strong loophole-free test of local realism

Author(s)
Lynden K. Shalm, Evan Meyer-Scott, B. G. Christensen, Peter L. Bierhorst, Michael A. Wayne, Deny Hamel, Martin J. Stevens, Thomas Gerrits, Scott C. Glancy, Michael S. Allman, Kevin J. Coakley, Shellee D. Dyer, Adriana E. Lita, Varun B. Verma, Joshua C. Bienfang, Alan L. Migdall, Yanbao Zhang, William Farr, Francesco Marsili, Matthew D. Shaw, Jeffrey Stern, Carlos Abellan, Waldimar Amaya, Valerio Pruneri, Thomas Jennewein, Morgan Mitchell, P. G. Kwiat, Richard P. Mirin, Emanuel H. Knill, Sae Woo Nam
We present a loophole-free violation of local realism using entangled photon pairs. We ensure that all relevant events in our Bell test are spacelike separated...

A significant-loophole-free test of Bell's theorem with entangled photons

Author(s)
Marissa Giustina, Marijn Versteegh, Soren Wengerowsky, Johannes Handsteiner, Armin Hochrainer, Kevin Phelan, Fabian Steinlechner, Johannes Koffler, Larsson Jan-Ake, Carlos Abellan, Waldimar Amaya, Valerio Pruneri, Morgan Mitchell, Joern Beyer, Thomas Gerrits, Adriana Lita, Krister Shalm, Sae Woo Nam, Thomas Scheidl, Rupert Ursin, Bernhard Wittmann, Anton Zeilinger
Local realism is the worldview in which physical properties of objects exist independently of measurement and where physical influences cannot travel faster...

Monolithic device for modelocking and stabilization of a frequency comb

Author(s)
Kevin L. Silverman, Richard P. Mirin, Ari D. Feldman, Todd E. Harvey, Thomas Schibli, Chien-Chung Lee, Yosuke Hayashi
We demonstrate a device that integrates a III-V semiconductor saturable absorber mirror with a graphene electro-optic modulator, which provides a monolithic...

Metrological challenges for measurements of key climatological observables: Oceanic salinity and pH, and atmospheric humidity. Part 1: overview

Author(s)
Rainer Feistel, Robert Wielgosz, Stephanie A. Bell, M F. Camoes, J R. Cooper, P Dexter, A G. Dickson, P Fisicaro, Allan H. Harvey, M Heinonen, Olaf Hellmuth, H J. Kretzschmar, J W. Lovell-Smith, Trevor J. McDougall, R Pawlowicz, S Seitz, Petra Spitzer, D Stoica, H Wolf, P Ridout
Water in its three ambient phases plays the dominant thermodynamic role for the functioning principles of the terrestrial climate system. Together with clouds...

Beam-Scanning for Rapid Coherent Raman Hyperspectral Imaging

Author(s)
Seungwan Ryu, Charles Camp, Ying Jin, Marcus T. Cicerone, Young Jong Lee
Coherent Raman imaging requires high peak power laser pulses to maximize the nonlinear multiphoton signal generation, but accompanying photo-induced sample...
