Complex Structures of Different CaFe 2 As 2 Samples

February 18, 2014
Author(s)
Bayrammurad Saparov, Claudia Cantoni, Minghu Pan, Thomas C. Hogan, William D. Ratcliff, Stephen D. Wilson, Katharina Fritsch, Bruce D. Gaulin, Athena S. Sefat
We use temperature-dependent X-ray and neutron diffraction, low-temperature scanning tunneling microscopy, and room-temperature scanning-transmission electron-microscopy, to investigate the interplay between magnetism and crystal structures in three CaFe

Humic Acid-Mediated Silver Nanoparticle Formation Under Environmentally Relevant Conditions

April 1, 2011
Author(s)
Nelson Akaighe, Robert I. MacCuspie, Divina A. Navarro, Diana S. Aga, Sarbajit Banerjee, Mary Sohn, Virender K. Sharma
The formation of silver nanoparticles (AgNPs) via reduction of silver ions (Ag+) in the presence of humic acids (HAs) under various environmentally relevant conditions is described. HAs tested were from Suwannee River (SUW), and samples of three sediment

Consistency of atomic data for the interpretation of beam emission spectra

Tripartite interactions between two phase qubits and a resonant cavity

August 1, 2010
Author(s)
Fabio Altomare, Jae Park, Katarina Cicak, Mika Sillanpaa, Michael S. Allman, Adam J. Sirois, Joshua Strong, Jed D. Whittaker, Raymond Simmonds
The ability to create and manipulate the entanglement of a large number of quantum systems lies at the heart of emerging quantum information technologies. Thus far, multipartite entanglement has been achieved using various forms of quantum bits (qubits)

Growth of Nanocrystalline Ceria Studied Using a USAXS Capillary Flow-Cell

July 1, 2006
Author(s)
Vincent A. Hackley, Andrew J. Allen, P R. Jemian, J M. Raitano, S W. Chan
Nanocrystalline ceria particles, with dimensions as small as 2 nm, have been prepared at room temperature by a soft chemical route using aqueous cerium nitrate and hexamethylenetetramine (HMT) as reactants. HMT decomposes slowly in aqueous solution

Genotyping SNPs Using a UV Photocleavable Oligonucleotide in MALDI-TOF MS

March 17, 2005
Author(s)
Peter M. Vallone, K Fahr, M Kostrzewa
Matrix assisted laser desorption time-of-flight mass spectrometry (MALDI-TOF MS) coupled with allele specific primer extension is a proven method for typing single nucleotide polymorphisms (SNPs). A novel modification upon this methodology is the

Atomic Spectroscopy at NIST 2001

June 1, 2001
Author(s)
Joseph Reader
The program in atomic spectroscopy at NIST continues to provide accurate reference data on spectral lines and energy levels for a wide variety of important applications. With spectrometers at NIST that can record spectra from the extreme ultraviolet (1 nm)

Structural investigation of (Sr 4-d Ca d )PtO 6 Using X-Ray Rietveld Refinement

August 16, 1999
Author(s)
Winnie K. Wong-Ng, James A. Kaduk, R A. Young, F Jiang
The structures of the solid solution series (Sr 4-δCa δ)PtO 6, with δ = 0, 0.85(1), 2, and 3, have been investigated using the Rietveld refinement technique with laboratory x-ray powder data. A complete solid solution between Sr and Ca was confirmed to
