DIC Challenge 2.0: Developing Images and Guidelines for Evaluating Accuracy and Resolution of 2D Analyses: Focus on the Metrological Efficiency Indicator

January 4, 2022
Author(s)
Philip Reu, EMC Jones, S.S. Fayad, B. Blaysat, E. Toussaint, Mark Iadicola, P. Lava, J Rethore, J. Yang, K. Bhattacharya, L. Yang, D. Deb, C.S.R. Vemulapati, M Klein, E Ando, E Roubin, O. Stamati, C Couture, Alexander Landauer, M. Liu, S Jaminion, T. Siebert, S.N. Olufsen
Background The DIC Challenge 2.0 follows on from the work accomplished in the first Digital Image Correlation (DIC) Challenge Reu et al. (Experimental Mechanics 58(7):1067, 1). The second challenge was required to better quantify the spatial resolution of

Ferromagnetic resonance and magnetization switching characteristics of perpendicular magnetic tunnel junctions with synthetic antiferromagnetic free layers

deyuan lyu, Delin Zhang, Daniel Gopman, Yang Lv, Onri Benally, Jian-Ping Wang
Perpendicular magnetic tunnel junctions (pMTJs) with synthetic antiferromagnetic (SAF) free layers were predicted and recently demonstrated to possess ultrahigh switching speed and ultralow switching current density. However, ferromagnetic resonance (FMR)

Evaluating Ventilation Performance

Author(s)
Andrew K. Persily
The evaluation of building ventilation performance is critical to understanding indoor contaminant transport dynamics and interpreting indoor contaminant measurements. However, ventilation performance involves many different issues and metrics that can

NIST Conference Papers Fiscal Year 2018, Volume 1: Engineering Laboratory

January 3, 2022
Author(s)
Kathryn Miller
NIST is committed to the idea that results of federally funded research are a valuable national resource and a strategic asset. To the extent feasible and consistent with law, agency mission, resource constraints, and U.S. national, homeland, and economic

A 3-DOF MEMS motion stage for scanning tunneling microscopy

January 1, 2022
Author(s)
Taekyung Kim, Jason J. Gorman
Piezoelectric tube scanners used in most conventional scanning tunneling microscopes (STM) are highly resonant mechanisms that require a low-bandwidth controller ( 1 kHz) to minimize ringing, which prohibitively limits scan speed. In addition, hysteresis

A Methodology for Modeling Interoperability for Smart Sensors in Smart Grids

January 1, 2022
Author(s)
Edward Griffor, Kang B. Lee, Gerald J. FitzPatrick, Eugene Song
Smart sensors in smart grids provide real-time data and status of bidirectional flows of energy for monitoring, protection, and control of grid operations to improve reliability and resilience. Smart sensor interoperability is major challenges for smart

A Methodology for Modeling Interoperability for Smart Sensors in Smart Grids

January 1, 2022
Author(s)
Edward Griffor, Yuyin Song, Kang B. Lee, Gerald J. FitzPatrick
Smart sensors in smart grids (SGs) can provide real-time data and status of modernized, bidirectional flows of energy, electrical power grids for monitoring, protection, and control of grid operations to improve reliability and resilience. Smart sensor

Core-shell and Egg-shell Zeolite Catalysts for Enhanced Hydrocarbon Processing

January 1, 2022
Author(s)
Thuy Tran Le, Kumari Shilpa, Choongsze Lee, Sungmin Han, Conan Weiland, Simon Bare, Paul Dauenhauer, Jeffrey Rimer
Developing structure-performance relationships with the underlying goal of optimizing known zeolite catalysts involves the manipulation of their physicochemical properties. Here, we systematically assessed the impact of mesoscopic gradients in acid site

Crystal structure and thermochromic behavior of the quasi-0D lead-free organic-inorganic hybrid compounds (C7H9NF)8M4I16 (M = Bi, Sb)

December 31, 2021
Author(s)
Winnie Wong-Ng, Xiochen Zhao, Yikai Fu, Yunlin Lei, Chao Wang, Wei Zhou, Shouyu Wang, Weifang Liu
Quasi 0-D lead-Free thermochromic organic-inorganic hybrid single crystals (C7H9NF)8M4I16 (M = Bi, Sb) were synthesized by a conventional solvothermal reaction method. The crystal structures were analyzed using single crystal X-ray diffraction (SXRD)
