Michael S. Bloom, Abby G. Wenzel, John W. Brock, Rebecca J. Wineland, Lori Cruze, Elizabeth R. Unal, Assem Jiyessova, Roger B. Newman, John Kucklick
… 95%CI: -0.28, 0.001) but not among African Americans (β=0.05; 95%CI=-0.09, 0.50). MiBP (OR=2.84; 95%CI: 1.22, 6.61) and MEOHP (OR=2.79; 95%CI: 1.05, 7.41) were associated with an overall higher SGA risk, and …

High accuracy, high dynamic range optomechanical accelerometry enabled by dual comb spectroscopy

September 20, 2023
Author(s)
David Long, Jasper Stroud, Benjamin Reschovsky, Yiliang Bao, Feng Zhou, Thomas W. LeBrun, David Plusquellic, Jason Gorman, Sean Bresler
Cavity optomechanical sensors offer exceptional sensitivity but interrogating the cavity motion with high accuracy and dynamic range has proven to be challenging. Here we employ a dual optical frequency comb spectrometer to readout a cavity optomechanical

Bi 12 O 17 Cl 2 with a Sextuple Bi-O Layer Composed of Rock-Salt and Fluorite Units and its Structural Conversion through Fluorination to Enhance Photocatalytic Activity

October 10, 2022

Daichi Kato, Osamu Tomita, Ryky Nelson, Maria A. Kirsanova, Richard Dronskowski, Hajime Suzuki, Chengchao Zhong, Cedric Tassel, Kohdai Ishida, Yosuke Matsuzaki, Craig Brown, Koji Fujita, Kotaro Fujii, Masatomo Yashima, Yoji Kobayashi, Akinori Saeki, Itaru Oikawa, Hitoshi Takamura, Ryu Abe, Hiroshi Kageyama, Tatiana E. Gorelik, Artem M. Abakumov
Layered bismuth oxyhalides with bilayered (Bi 2O 2) fluorite slabs are promising visible-light photocatalysts because of the ability to control the valence band levels. Here we show that a structurally uncharacterized Bi 12O 17Cl 2, which has been

Certification of Standard Reference Material(R) 3655 Glycans in Solution (Frozen)

April 12, 2022
Author(s)
Mark Lowenthal, Blaza Toman, Brian Lang, Karen W. Phinney
Standard Reference Material (SRM) 3655 is intended primarily for use as a calibration standard for the measurement of enzymatically released N-linked glycans. Applications of SRM 3655 include the benchmarking and comparability of analytical techniques, as

Dopant Location Identification in Nd 3+ -Doped TiO 2 Nanoparticles

October 12, 2021
Author(s)
W Li, A I. Frenkel, Joseph Woicik, C Ni, S I. Shah
Doping large bandgap semiconductors is typically done in order to enhance photocatalytic, photovoltaic and other chemical and optoelectronic properties. The identification of dopant position and its local environment is essential to exploring the doping

Final Report of the SIM 60 Co Air-Kerma Comparison (KCDB Entry SIM.RI (I)-K1)

October 12, 2021
Author(s)
C K. Ross, K Shortt, M Saravi, A Meghzifene, V M. Tovar, R A. Barbosa, C N. da Silva, F Gutt, Stephen M. Seltzer
Transfer chambers were used to compare the standards for 60Co air kerma maintained by seven laboratories. Six of the laboratories were members of the Sistema Interamericano de Metrolog a (SIM) regional metrological organization while the seventh was the

Subsolidus Phase Relationships in the AO-AI 2 O 3 -Nb 2 O 5 (A=Ca, Sr) Systems

October 12, 2021
Author(s)
Julia Y. Chan, Wilma Feb-Ayala, J. M. Loezos, L D. Rotter, Lyle E. Levine, Richard G. Geyer
Dielectric ceramics for wireless communications exhibiting modest permittivity, high quality factor (Q), and near-zero temperature coefficient are needed for high-frequency, high power applications. Efforts are in progress to replace Ta 2O 5-based ceramics

Transient heating in fixed length optical cavities for use as temperature and pressure standards

February 25, 2021
Author(s)
Jacob Edmond Ricker, Kevin O. Douglass, Jay H. Hendricks, Jack Stone, Sergei Syssoev, Sefer Avdiaj
Optical refractometry techniques can enable realization of both pressure and temperature directly from properties of the gas. For achieving the highest possible accuracy, temperature uniformity across the refractometer must be less than 1 mK. However, the

Lifetime-Limited Interrogation of Two Independent 27Al+ Clocks using Correlation Spectroscopy

December 9, 2020
Author(s)
Ethan Clements, May E. Kim, Kaifeng Cui, Aaron M. Hankin, Samuel M. Brewer, Jose Valencia, Jwo-Sy Chen, Chin-wen Chou, David Leibrandt, David Hume
Laser decoherence limits the stability of optical clocks by broadening the observable resonance linewidths and adding noise during the dead time between clock probes. Correlation spectroscopy avoids these limitations by measuring correlated atomic

Dew-point Measurements For Water In Compressed Carbon Dioxide

August 6, 2015
Author(s)
Christopher W. Meyer, Allan H. Harvey
When transporting CO2 for sequestration, it is important to know the water dew point in order to avoid condensation that can lead to corrosion. We have constructed a flow apparatus to measure the water content at saturation in a compressed gas. A saturator

Experimental measurements and noise analysis of a cryogenic radiometer

July 10, 2014
Author(s)
Solomon I. Woods, Timothy M. Jung, Adriaan C. Carter, Raju V. Datla , Stephen M. Carr
A cryogenic radiometer device, intended for use as part of an electrical-substitution radiometer, was measured at low temperature. The device consists of a receiver cavity mechanically and thermally connected to a temperature-controlled stage through a
