Electric-field imaging using polarized neutrons

Author(s)
Y.- Y. Jau, Daniel S. Hussey, Thomas R. Gentile, Wangchun Chen
We experimentally demonstrate that electrically neutral particles, neutrons, can be used to directly visualize the electrostatic field inside a target volume...

Continued Growth of IEEE RAS Standards Efforts

Author(s)
Craig I. Schlenoff
This has been a very eventful quarter for standardization efforts within the IEEE Robotics and Automation Society (RAS). Even the virtual nature of the 2020...

Protocol for Light-Shift Compensation in a Continuous-Wave Microcell Atomic Clock

Author(s)
Moustafa A. Hafiz, Remy Vicarini, Nicolas Passilly, Claudio Calosso, Vincent N. Maurice, Juniper Pollock, V Yudin, John Kitching, Rodolphe Boudot
Light shifts are known to be an important limitation to the mid- and long-term fractional frequency stability of different types of atomic clocks. In this...

Development of NIST Atomic Databases and OnlineTools

Author(s)
Yuri Ralchenko, Alexander Kramida
Over the last 25 years, the atomic standard reference databases and online tools developed at the National Institute of Standards and Technology (NIST) provide...

Photorealistic full-color nanopainting enabled by a low-loss metasurface

Author(s)
Pengcheng Huo, Maowen Song, Wenqi Zhu, Cheng Zhang, Lu Chen, Henri Lezec, Yanqing Lu, Amit Agrawal, Ting Xu
We design and experimentally demonstrate a TiO2 metasurface that enables full-color generation and ultrasmooth color brightness variations. The reproduced...

Measurement and Standardization Challenges for Exosome-Based Delivery Vectors

Author(s)
Bryant Nelson, Hao-Wei Wang, Samantha Maragh, Paul DeRose, Elzafir B. Elsheikh, Wyatt Vreeland, Ionita Ghiran, Jennifer Jones
Extracellular vesicles (EVs), and in particular exosomes, have the potential to revolutionize the development and efficient delivery of clinical therapeutics...

Reducing the Measurement Time of Exact NOEs by Non-Uniform Sampling

Author(s)
Parker J. Nichols, Alexandra Born, Morkos A. Henen, Dean Strotz, David N. Jones, Frank Delaglio, Beat Vogeli
We have previously reported on the measurement of exact NOEs (eNOEs), which yield a wealth of additional information in comparison to conventional NOEs. We have...

Measurement of the 2P1/2–2P3/2 fine structure splitting in fluorine-like Kr, W, Re, Os and Ir

Author(s)
Galen O'Neil, Samuel C. Sanders, Paul Szypryt, Dipti Goyal, Amy Gall, Yang Yang, Samuel M. Brewer, William Doriese, Joseph Fowler, Daniel Swetz, Joseph Tan, Joel Ullom, Andrey V. Volotka, Endre Takacs, Yuri Ralchenko
Quantum electrodynamics (QED) is currently considered to be one of the most accurate theories of fundamental interactions. As its extraordinary precision offers...

Modeling Temperature Effects on a Coriolis Mass Flowmeter

Author(s)
Fabio O. Costa, Jodie Gail Pope, Keith A. Gillis
Coriolis mass flowmeters are known to be stable, have low uncertainty (± 0.1 %), and are insensitive to fluid properties. This meter type is used for many...
