IFCC working group recommendations for correction of bias caused by non-commutability of a certified reference material used in the calibration hierarchy of an end-user measurement procedure

June 1, 2020
Author(s)
Johanna Camara, W. Greg Miller, Jeffrey R. Budd, Neil Greenberg, Weykamp Cas, Harald Althaus, Heinz Schimmel, Mauro Panteghini, Vincent Delatour, Ferruccio Ceriotti, Thomas Keller, Douglas Hawkins, Robert Rej, Finlay MacKenzie, Elina van der Hagen, Hubert W. Vesper
Establishing metrological traceability to a matrix-based certified reference material (CRM) that has been validated to be commutable among a group of measurement procedures (MPs) is central to producing equivalent results for a measurand in clinical

Magnetic Field Frustration of the Metal-Insulator Transition in V 2 O 3

June 1, 2020
Author(s)
J. Trastoy, A. Camjayi, J. del Valle, Y. Kalcheim, J.-P. Crocombette, Dustin A. Gilbert, Julie Borchers, J. E. Villegas, D. Ravelosona, M. J. Rozenberg, Ivan K. Schuller
Despite decades of efforts, the origin of metal-insulator transitions (MITs) in strongly-correlated materials remains one of the main longstanding problems in condensed-matter physics. An archetypal example is V 2O 3, which undergoes simultaneous

Progress Towards Operation of a Deuterium Cold Neutron Source at the NCNR

June 1, 2020
Author(s)
John M Jurns, Michael Middleton, Robert E. Williams
The NIST Center for Neutron Research (NCNR) operates a 20 MW research reactor that produces neutrons for a suite of 30 neutron scattering instruments. 70% of these instruments use cold neutrons (E 2), which is in turn cooled by a recently commissioned 7 kW

Reconciling temperature-dependent factors affecting mass transport losses in polymer electrolyte membrane electrolyzers

June 1, 2020
Author(s)
Jacob LaManna, Aimy Bazylak, ChungHyuk Lee, Jason K. Lee, Kieran F. Fahy, Eli Baltic, Daniel S. Hussey, David L. Jacobson
In this work, we investigated the impact of temperature on two-phase transport in low temperature (LT)-polymer electrolyte membrane (PEM) electrolyzer anode flow channels via in operando neutron imaging and observed a decrease in mass transport

Securing web transactions TLS server certificate management:

June 1, 2020
Author(s)
Mehwish Akram, William C Barker, Rob Clatterbuck, Donna Dodson, Brandon Everhart, Jane Gilbert, William Haag, Brian Johnson, Alexandros Kapasouris, Dung Lam, Brett Pleasant, Mary Raguso, Murugiah Souppaya, Susan Symington, Paul Turner, Clint Wilson

CERTIFICATION OF SRM 640f LINE POSITION AND LINE SHAPE STANDARD FOR POWDER DIFFRACTION

May 31, 2020
Author(s)
David R. Black, Marcus Mendenhall, Albert Henins, James Filliben, James Cline
The National Institute of Standards and Technology (NIST) certifies a suite of Standard Reference Materials (SRMs) to be used to evaluate specific aspects of instrument performance of both X-ray and neutron powder diffractometers. This report describes SRM

Comparison of Open and Solid Falling Retroreflector Gravimeters

May 29, 2020
Author(s)
Neil Ashby, Derek Van Westrum
We study whether the optical properties of a solid glass retroreflector influence the value of the acceleration of gravity $g$ determined by dropping both solid and open retroreflectors in an absolute ballistic gravimeter. The retroreflectors have

Error Estimation and Enhanced Stiffness Sensitivity in Contact Resonance Force Microscopy with a Multiple Arbitrary Frequency Lock-In Amplifier (MAFLIA)

May 29, 2020
Author(s)
Erin Flater, Arya Mugdha, Saurabh Gupta, William Hudson, Abbigail Fahrenkamp, Jason Killgore, Jesse Wilson
In contact resonance force microscopy and related dynamic atomic force microscopy methods, an accurate description of the real-time cantilever dynamics is essential to the mapping of local material properties, such as viscoelasticity, piezo response, and

Experimental investigation of structural steel beams subjected to localized fire

May 29, 2020
Author(s)
Selvarajah Ramesh, Lisa Y. Choe, Chao Zhang
This paper presents an experimental behavior of unprotected W16 × 26 steel beams subjected to localized fire. Beam specimens were either simply supported or connected to steel columns via all bolted double angle connections. Two test fires, steady or

Foundational Cybersecurity Activities for IoT Device Manufacturers

May 29, 2020
Author(s)
Michael J. Fagan, Katerina N. Megas, Karen Scarfone, Matthew Smith
Internet of Things (IoT) devices often lack device cybersecurity capabilities their customers-- organizations and individuals--can use to help mitigate their cybersecurity risks. Manufacturers can help their customers by improving how securable the IoT
