An electronic measurement of the Boltzmann constant

Author(s)
Samuel P. Benz, Alessio Pollarolo, Jifeng Qu, Horst Rogalla, Chiharu Urano, Weston L. Tew, Paul D. Dresselhaus, D. R. White
The Boltzmann constant was measured by comparing the Johnson noise of a resistor at the triple point of water with a quantum-based voltage reference signal...

Electron Ionization Mass Spectra of Alkylated Sulfabenzamides

Author(s)
Nino G. Todua, Kirill V. Tretyakov, Roman S. Borisov, Dmitry I. Zhilyaev, Vladimir G. Zaikin, Stephen E. Stein, Anzor I. Mikaia
Mono-, di- and trialkyl derivatives of "sulfabenzamide" (N-4-aminophenylsulfonyl-benzamide) are prepared and their EI mass spectra are examined. It is found...

Magnetization Reversal Mechanisms in Heusler Alloy Spin Valves

Author(s)
T. P. Ginley, Julie Borchers, Brian Kirby, Cindi L. Dennis, Matthew J. Carey, J. R. Childress
Ferromagnetic layers composed of Heusler alloys, which are predicted to be 100% spin polarized in bulk, have been incorporated into spin-valve sensors to...

CONTINUOUS FLOW ENZYME-CATALYZED POLYMERIZATION IN A MICROREACTOR

Author(s)
Santanu S. Kundu, Atul S. Bhangale, William E. Wallace, Kathleen M. Flynn, Charles M. Guttman, Richard Gross, Kathryn L. Beers
Enzymes immobilized on solid supports are increasingly used for chemical transformation because the process is greener and sustainable. Here we use...

Neutron Imaging of Lithium Concentration in Battery Pouch Cells

Author(s)
Daniel S. Hussey, David L. Jacobson, Jason B. Siegel, C. D. Stefan, Xinfan Lin, David Gorsich
This paper shows how neutron radiography can be used for in situ quantification of the lithium concentration across battery electrodes, a critical physical...

Time Through the Air

Author(s)
John P. Lowe
A brief history of the NIST WWVB low frequency (LF) radio station. This includes recent attempts at creating a sister station on the eastern side of the United...

Thoughts on Higher Education and Scientific Research

Author(s)
Jeffrey M. Voas, George Hurlburt, Keith Miller, Phillip Laplante, Bret Michael
The notion of a "tipping point" isn't new, al though the concept has relevance in differing ways. Academia seems to be at a tipping point, whereby the steady...
