Metallo-N-Heterocycles - A New Family of Hydrogen Storage Material

April 1, 2020
Author(s)
Khai Chen Tan, Yang Yu, Ruting Chen, Teng He, Zijun Jing, Qijun Pei, Jintao Wang, Yong Shen Chua, Anan Wu, Wei Zhou, Hui Wu, Ping Chen
Storing hydrogen efficiently in condensed material under mild conditions is a key technique challenge. Here, we developed a new family of hydrogen storage material spanning across the domain of inorganic and organic hydrides, namely metalorganic hydrides

Methods to improve the dimensional measurement accuracy of a motion tracking system

April 1, 2020
Author(s)
Shendong Shi, Balasubramanian Muralikrishnan, Vincent D. Lee, Daniel S. Sawyer
Photogrammetry based motion tracking systems are widely used in entertainment, medicine, sports, and other industries for low accuracy positioning applications. Camera-based systems track cooperative markers on objects to obtain their real-time positions

Mid-Infrared Frequency Comb Generation and Spectroscopy with Few-Cycle Pulses and hd2TH Nonlinear Optics

April 1, 2020
Author(s)
Alexander Lind, Abijith S. Kowligy, Henry R. Timmers, Flavio Caldas da Cruz, Nima Nader, Myles C. Silfies, Thomas K. Allison, Scott Papp, Scott Diddams
The mid-infrared atmospheric window of 3–5.5 μm holds valuable information regarding molecular composition and function for fundamental and applied spectroscopy. Using a robust, mode-locked fiberlaser source of 11 fs pulses in the near infrared, we

Using Microprojectiles to Study the Ballistic Limit of Polymer Thin Films

April 1, 2020
Author(s)
Shawn H. Chen, Amanda J. Souna, Christopher L. Soles, Stephan J. Stranick, Edwin P. Chan
The dynamic impact between a particle and a planar material is important in many high impact events, andthereisagrowingneedtocharacterizethemechanicalpropertiesoflight-weightpolymeric materials at dynamic loading conditions. Here, a laser-induced

Auto-tuning of double dot devices it in situ with machine learning

March 31, 2020
Author(s)
Justyna Zwolak, Thomas McJunkin, Sandesh Kalantre, J. P. Dodson, Evan MacQuarrie, D. E. Savage, M. G. Lagally, S N. Coppersmith, Mark A. Eriksson, Jacob Taylor
The current practice of manually tuning quantum dots (QDs) for qubit operation is a relatively time- consuming procedure that is inherently impractical for scaling up and applications. In this work, we report on the \it in situ} implementation of a

Global City Teams Challenge Public Safety SuperCluster Progress Report 2018-2019

March 31, 2020
Author(s)
Sokwoo Rhee, Brenda Bannan, Samantha Dubrow, Michael Dunaway, Dean Skidmore, Elisa Torres
NIST co-hosted the 2018-2019 GCTC Smart and Secure Cities and Communities Challenge (SC3) program with DHS S&T and NTIA. The objective was to encourage participating teams to include cybersecurity and privacy as integral project elements alongside goals

Nanoscale MOSFET as a potential Room-Temperature Quantum Current Source

March 31, 2020
Author(s)
Kin P. Cheung, Jason P. Campbell
Nanoscale metal-oxide-semiconductor field-effect-transistors (MOSFETs) with only one defect at the interface can potentially become a single electron turnstile linking frequency and electronic charge to realize the elusive quantized current source. Charge

UE-to-Network Relay Discovery in ProSe-enabled LTE Networks

March 30, 2020
Author(s)
Samantha M. Gamboa Quintiliani, Alexandre C. Moreaux, David W. Griffith, Richard A. Rouil
The UE-to-Network Relay functionality was introduced to Long Term Evolution (LTE) cellular networks in Release 13. In this technology, User Equipment (UEs) acting as Relay UEs are used to extend network coverage to cell-edge and out-of-coverage Remote UEs
