Quantitative Electron Probe Microanalysis of Rough Targets

October 16, 2008
Author(s)
Dale E. Newbury
Rough samples with topography on a scale that is much greater than the micrometer dimensions of the electron interaction volume present an extreme challenge to quantitative electron beam x-ray microanalysis with energy dispersive x-ray spectrometry

Quantized Rotation of Atoms From Photons With Orbital Angular Momentum

October 16, 2008
Author(s)
Mikkel Andersen, Changhyun Ryu, Pierre Clade, Vasant Natarajan, A Vaziri, Kristian Helmerson, William D. Phillips
Light can carry two kinds of angular momentum: Spin angular momentum (SAM) associated with its polarization and orbital angular momentum (OAM) associated with its spatial mode [1, 2]. The coupling of optical SAM to atoms has been known for over a century

Quantum Charge Fluctuations and the Polarizability of the Single Electron Box

October 16, 2008
Author(s)
Konrad Lehnert, B A. Turek, K Bladh, L F. Spietz, D Gunnarsson, P Delsing
We measure the average charge on a single-electron box, with an accuracy of 10 -3 e as a function of an externally applied potential. At this accuracy, we observe that the total capacitance of the box is a function of temperature, of external potential and

Quantum Teleportation Between Nanomechanical Modes

October 16, 2008
Author(s)
Lin Tian, Stephen Carr
We study a quantum teleportation scheme between two nanomechanical modes without local interaction. The nanomechanical modes are linearly coupled to and connected by the continuous variable modes of a superconducting circuit made of transmission line and

Quantum Teleportation with Atomic Qubits

October 16, 2008
Author(s)
J Chiaverini, T Schaetz, Joseph W. Britton, Wayne M. Itano, John D. Jost, Emanuel Knill, C. Langer, Dietrich Leibfried, R Ozeri, David J. Wineland

Radiation Chemistry of Phenols

October 16, 2008
Author(s)
Pedatsur Neta, S Steenken
This chapter summarizes the radiation chemistry of phenols. It includes studies on the radiation chemistry of phenols in aqueous solutions, in organic solvents, in solid matrices, and in the gas phase.

Radioanalytical Emergency Response Exercise

October 16, 2008
Author(s)
Kenneth G. Inn, Iisa Outola, S Nour, Hiromu Kurosaki, L Albin, A Berne
The National Institute of Standards and Technology (NIST Radiochemistry Intercomparison Program) and the Environmental Measurements Laboratory (EML Performance Testing 0904) recently conducted two independent radiological emergency preparedness exercises

Raman Microspectroscopy of Some High Explosives, Revisited

October 16, 2008
Author(s)
E S. Etz, S V. Roberson, J Greg Gillen
Current NIST research is discussed on the characterization by micro-Raman spectroscopy of several high explosives (HES). The RamanSpectra are evaluated relative to the thermal decomposition of the HES to explain the reactions that produce secondary ion

Reactive Intermediates in Combustion

October 16, 2008
Author(s)
John K. Merle, Christopher M. Hadad
This chapter provides an introduction into the chemistry of reactive intermediates that are typically generated by combustion. Several aspects of combustion chemistry are reviewed: (i) low- and high-temperature mechanisms for saturated and unsaturated

Realizing the SI in the 21st Century at NIST

October 16, 2008
Author(s)
K B. Gebbie
As it embarks on its second 100 years, the National Institute of Standards and Technology is developing new approaches to realizing and disseminating the SI. Efforts to improve the realization of the second include development of a laser-cooled cesium

Really Cool Molecules

October 16, 2008
Author(s)
Paul S. Julienne
Ultracold molecules have been made by applying a time-dependent magnetic field to a dilute quantum gas of ultracold trapped fermionic atoms. This raises the prospect of creating novel superfluids and molecular Bose-Einstein condensates.

Recent Developments in Y STR and Y SNP Analysis

October 16, 2008
Author(s)
John Butler
This article reviews new genetic markers on the Y chromosome and methods for analyzing these short tandem repeat (STR) and single nucleotide polymorphism (SNP) loci. Relative chromosomal locations for over 50 Y STRs are described along with their repeat

Reciprocity in Reverberation Chamber Measurement

October 16, 2008
Author(s)
David A. Hill
Even though reverberation chambers have been used primarily for radiated immunity testing, they are reciprocal devices that are equally applicable for radiated emissions testing. This short paper presents the theory for radiated emissions testing and uses
