Correlation Between Morphology and Device Performance of pBTTT:PC 71 BM Solar Cells

October 1, 2016
Author(s)
Wenluan Zhang, Hao Shen, Brett W. Guralnick, Brian Kirby, Ngoc A. Nguyen, Roddel Remy, Charles Majkrzak, Michael E. Mackay
Phenyl-C 71-butyric acid methyl ester (PC 71BM) could intercalate between the side-chains of poly(2,5-bis(3-tetradecylthiophen-2-yl)thieno[3,2-b]thiophene (pBTTT) creating a stable co-crystal structure, so optimal solar cell performance was obtained at

Three-level Haldane-like model on a dice optical lattice

September 21, 2015
Author(s)
Ian B. Spielman, T. Andrijauskas, E. Anisimovas, M. Raciunas, A. Mekys, V. Kudriasov, G. Juzeliunas
We consider ultracold atoms in a two-dimensional optical lattice of the dice geometry in a tight-binding regime. The atoms experience a laser-assisted tunneling between the nearest neighbor sites of the dice lattice accompanied by the momentum recoil. This

Theoretical Analysis of a Magnetophoresis-Diffusion T-Sensor Immunoassay

August 6, 2013
Author(s)
Thomas P. Forbes, Matt S. Munson, Samuel P. Forry
Microfluidic immunoassays have demonstrated broad application to the detection and quantification of analytes ranging from small drug molecules to large proteins and biomolecules. These systems exhibit short length scales, reduced sample volumes, and

Superconductivity in Nb-Sn thin films of stoichiometric and off-stoichiometric compositions

December 7, 2012
Author(s)
Matthijs Mentink, John E. Bonevich, Marc Dhalle, Daniel Dietderich, Arno Godeke, Frances Hellman, Herman Ten Kate
Binary Nb-Sn thin film samples are fabricated and characterized in terms of their composition, morphology and superconducting properties. Nb-Sn is magnetron-sputtered onto heated R-plane sapphire substrates at 700 C, 800 C, and 900 C, using a custom-built

Calibration of Ultra-Low Infrared Power at NIST

July 20, 2010
Author(s)
Solomon I. Woods, Stephen M. Carr, Adriaan C. Carter, Timothy M. Jung, Simon G. Kaplan, Raju V. Datla
The Low Background Infrared (LBIR) facility has developed and tested the components of a new detector for calibration of infrared powers down to 1 pW, with 0.1% uncertainty. Calibration of such low powers could be valuable for the quantitative study of

Active Vibration-induced PM Noise Control in Optical Fibers: Preliminary Studies

May 29, 2007
Author(s)
David A. Howe, Archita Hati, Craig Nelson, Jennifer A. Taylor, Neil Ashby
Vibration causes mechanical distortions in fiber-optic transmission lines that induce time (phase) fluctuations. RF systems are increasingly using optical fibers in various ways and must occasionally operate in environments with acoustic and structure-born

Guidelines for Media Sanitization

September 1, 2006
Author(s)
Richard L. Kissel, Matthew A. Scholl, Steven Skolochenko, Xiang Li
Information systems capture, process, and store information using a wide variety of media. This information is located not only on the intended storage media but also on devices used to create, process, or transmit this information. These media may require

RNA and RNA-Protein Complexes as Targets for Therapeutic Intervention

May 1, 2002
Author(s)
E S. DeJong, B. Luy, John Marino
Today, the majority of pharmaceuticals developed to treat cancers and viral/bacterial infections target cellular, bacterial or viral proteins known to be associated with a given pathology. Although proteins are the focus of most current drug discovery

Structure Determination of a Polymeric Amorphous Chain Compound AlB 4 H 11

August 21, 2012
Author(s)
Xuenian Chen, Yongsheng Zhang, Yongli Wang, Wei Zhou, Douglas A. Knight, Teshome B. Yisgedu, Zhenguo Huang, Hima K. Lingam, Beau Billet, Terrence J. Udovic, Gilbert M. Brown, Sheldon G. Shore, Christopher M. Wolverton, Ji-Cheng Zhao
The structure of the amorphous aluminoborane compound AlB 4H 11 was identified through a collaborative study closely coupling theoretical predictions via the PEGS+DFT approach with experimental measurements using IR, NMR, and neutron vibrational

Capture and isolation of highly-charged ions in a compact Penning trap: V12

December 4, 2013
Author(s)
Samuel Brewer, Nicholas D. Guise, Joseph Tan
Room-temperature, compact Penning traps have been shown recently to be useful for capture and storage of highly-charged ions extracted from an EBIT ion source at the National Institute of Standards and Technology (NIST). Highly-charged argon and neon ions

Securing the Future of NMR Metabolomics Reproducibility: A Call for Standardized Reporting

Andrew Ferdinand, Zheng Luo, Sindhu Jammi, Zachary Newman, Grisha Spektor, Okan Koksal, Akash Rakholia, Daniel Sheredy, Parth Patel, Travis Briles, Wenqi Zhu, Martin Machai Boyd, Amit Agrawal, Scott Papp
We report on experiments generating a magneto-optical trap (MOT) of 88-strontium (88Sr) atoms at microkelvin temperature, using integrated-photonics devices. With metasurface optics integrated on a fused-silica substrate, we generate six-beam, circularly p

SAND: automated time-domain modeling of NMR spectra applied to metabolite quantification
