Ullom, Eberhard Widmann, Shinya Yamada, Johann Zmeskal, Daniel S. Swetz

A performance evaluation of superconducting transition-edge sensors (TESs) in the environment of a pion beam line at a particle accelerator is presented. Averaged across the 209 functioning sensors in the array, the achieved energy resolution is 5.2 eV

Spectrum and Energy Levels of Five-Times Ionized Zirconium (Zr VI)

January 5, 2016

Author(s)

Joseph Reader, Mark D. Lindsay

The spectrum of five-times-ionized zirconium Zr VI was observed from 160 Å to 2000 Å with sliding spark discharges on 10.7-m normal- and grazing-incidence spectrographs. The existing analysis of this spectrum [Khan Z. A. et al. 1985 Phys. Scr. 31 837] was

Practical limitations of aerosol separation by a tandem differential mobility analyzeraerosol particle mass analyzer

January 4, 2016

Author(s)

James G. Radney, Christopher D. Zangmeister

A cavity ring-down spectrometer and condensation particle counter were used to investigate the limitations in the separation of singly and multiply charged aerosol particles by a tandem differential mobility analyzer (DMA) and aerosol particle mass

Beam-Scanning for Rapid Coherent Raman Hyperspectral Imaging

December 14, 2015

Author(s)

Seungwan Ryu, Charles Camp, Ying Jin, Marcus T. Cicerone, Young Jong Lee

Coherent Raman imaging requires high peak power laser pulses to maximize the nonlinear multiphoton signal generation, but accompanying photo-induced sample damage often poses a challenge to microscopic imaging studies. We demonstrate that a beam-scanning

Chloride Incorporation Process in CH3NH3PbI3-xClx Perovskites via Nanoscale Bandgap Maps

December 9, 2015

Author(s)

Jungseok Chae, Qingfeng Dong, Jinsong Huang, Andrea Centrone

CH3NH3PbI3-xClx perovskites enable fabrication of highly efficient solar cells. Chloride ions benefit the morphology, carrier diffusion length and stability of perovskite films; however, whether those benefits stem from the presence of Cl- in the precursor

Observation of Iron Spin-States using Tabletop X-ray Emission Spectroscopy and Microcalorimeter Sensors

December 2, 2015

Author(s)

Young Il Joe, Galen C. O'Neil, Luis Miaja Avila, Joseph W. Fowler, Kevin L. Silverman, Daniel S. Swetz, Joel N. Ullom, Ralph Jimenez

X-ray emission spectroscopy (XES) is a powerful probe of the electronic and chemical state of elemental species embedded within more complex compounds. X-ray sensors that combine high resolving power and high collecting efficiency are desirable for photon

Making Contact to Molecular Layers: Linking Large Ensembles of Molecules to the Outside World

November 4, 2015

Author(s)

Christina A. Hacker, Sujitra J. Pookpanratana, Curt A. Richter, Mariona Coll

In this chapter we examine the various approaches to making electrical contact to large area molecular junctions. We will highlight the experimental concerns that one must consider and the various approaches to make reliable structures and characterize the

First far-infrared high resolution analysis of the nu6 band of phosgene 35Cl2CO and 35Cl37CLCO

Author(s)

Walter J. Lafferty

A Fourier transform spectrum of phosgene (Cl2CO) has been recorded in the 22.5 μm spectral region at a resolution of 0.00102 cm-1 using a Bruker IFS125HR spectrometer coupled with synchrotron radiation leading to the observation of the ν6 vibrational bands

Determination of 3-D molecular orientation by polarization broadband CARS spectroscopy

October 30, 2015

Author(s)

Young J. Lee

Theoretical description is presented about a new analysis method to determine 3-diminsional (3-D) molecular orientation by concurrently analyzing polarization profiles of multiple Raman modes measured by broadband coherent anti-Stokes Raman scattering

Zero to pi continuously controllable cross-phase modulation in a Doppler-broadened N-type electromagnetically-induced-transparency medium

October 29, 2015

Author(s)

Lu Deng, Edward W. Hagley, R B. Li, C J. Zhu

We demonstrate an observation of zero to π continuously controllable cross-phase- modulation based on an N-type electromagnetically-induced-transparency scheme in a room-temperature 87Rb vapor. We theoretically and experimentally show that the signal field

Abiotic bromination of soil organic matter

October 15, 2015

Author(s)

Bruce D. Ravel, Alessandra C. Leri

Biogeochemical transformations of plant-derived soil organic matter (SOM) involve complex abiotic and microbially mediated reactions. One such reaction is halogenation, which occurs naturally in the soil environment and has been associated with enzymatic
