Electrical and Electroluminescence Evaluation of 17 Year Old Monocrystalline Silicon Building Integrated Photovoltaic Modules

December 25, 2023
Author(s)
Andrew Shore, Tali Schlenoff, Bakary Coulibaly, David Navon, Stephanie Moffitt, Brian P. Dougherty, Behrang Hamadani
Longterm reliable operation of photovoltaic modules is necessary to ensure the technology is key to reducing the cost of solar energy. However, degradation mechanisms in the field are not always consistent or predictable. We present a dataset of 72

Intra-grain local luminescence properties of CdSe0.1Te0.9 Thin Films

December 25, 2023
Author(s)
Ganga Neupane, Behrang Hamadani, David Albin, Joel Duenow, Matthew Reese, Susanna Thon
We report on the local photoluminescence properties of grains and grain boundaries of CdSe0.1Te0.9 thin film deposited by the colossal grain growth method using a wide-field hyperspectral imaging technique. We observed significant variations in the

System-Level Evaluation of 5G NR UE-Based Relays

December 25, 2023
Author(s)
Samantha Gamboa Quintiliani, Aziza Ben Mosbah, Wesley Garey, Chunmei Liu, Richard A. Rouil
The notion of UE-based relays started with the introduction of Proximity Services (ProSe) and Device-to-Device (D2D) communication, and evolved with the adaptation of the Fifth Generation (5G) New Radio (NR) interface. While the main goal of relays is to

Ultra-Low Phase Noise Frequency Division with Array of Direct Digital Synthesizers

December 25, 2023
Author(s)
Marco Pomponio, Archita Hati, Craig Nelson
In this article, we present a four-channel direct digital synthesis (DDS) design that operates with a common clock ranging from 500 MHz to 24 GHz and generates output frequencies up to 1.75 GHz. A key feature of this board is its custom field-programmable

Stability-Enhanced Cisplatin Gold Nanoparticles as Therapeutic Anticancer Agents

December 22, 2023
Author(s)
Tae Joon Cho, Vytas Reipa, John Pettibone, Justin Gorham, Allesandro Tona, Aaron Johnston-Peck, Bryant C. Nelson, Vincent Hackley
Using dendron chemistry, we developed stability-enhanced carboxylate surfacemodified (negatively charged dendron) AuNPs (Au-NCD). Since the carboxylate surface of Au- NCD is optimal for complexation with cisplatin (Pt) moieties, we further synthesized Pt

Cybersecurity of Genomic Data

December 20, 2023
Author(s)
Ronald Pulivarti, Natalia Globus, Frederick R. Byers, Justin Wagner, Justin Zook, Samantha Maragh, Jennifer McDaniel, Kevin Wilson, Martin Wojtyniak, Brett Kreider, Ann-Marie France, Sallie Edwards, Tommy Morris, Jared Sheldon, Scott Ross, Phillip Whitlow
Genomic data has enabled the rapid growth of the U.S. bioeconomy and is valuable to the individual, industry, and government because it has multiple intrinsic properties that in combination make it different from other types of high value data which

Comparison of Direct and Indirect Measures of Transport Efficiency in Single Particle ICP-MS

December 16, 2023
Author(s)
Karen Murphy, Antonio Montoro Bustos, Lee L. Yu, Monique Johnson, Michael R. Winchester
Accurate calibration of the fraction of introduced sample that is transported to the plasma, termed "transport efficiency" (TE), is required for spICP-MS measurement of particle number concentration (PNC) and for measurement of particle size (diameter, PS)

Picoliter Drop Deposition of SnO2 Nanoparticles onto Microsensor Platforms

December 14, 2023
Author(s)
Elvin Beach, Kurt D. Benkstein, Krenar Shqau, Christopher Montgomery, Patricia Morris, Stephen Semancik
Microhotplates produced by micromachining processes provide a robust substrate for miniaturized solid-state gas sensors; however, it can be challenging to locally deposit solution-suspended nanomaterials for sensing directly onto these small (≈ 100 µm), 3

Recommendations from the Ocean Carbonate System Intercomparison Forum: Quantifying and reducing uncertainties in the calculations of carbonate system equilibrium in the oceans

December 14, 2023
Author(s)
Brendan Carter, Jonathan Sharp, Andrew Dickson, Marta Alvarez, Michael Fong, Maribel Garcia-Ibanez, Ryan Woosley, Takeshita Yuichiro, Leticia Barbero, Robert Byrne, Wei-Jun Cai, Melissa Chierici, Simon Clegg, Regina Easley, Andrea Fassbender, Kalla Fleger, Xinyu Li, Macarena Martin-Mayor, Katelyn Schockman, Aleck Wang Zhaohui
The ocean carbonate system is critical to monitor because it plays a major role in regulating Earth's climate and marine ecosystems. It is monitored using a variety of measurements, and it is commonly understood that all major components of the seawater

Spatially-Dependent Model for Rods and Cones in the Retina

December 14, 2023
Author(s)
Daniel M. Anderson, Danielle Brager, Anthony J. Kearsley
We develop a mathematical model for photoreceptors in the retina. We focus on rod and cone outer segment dynamics and interactions with a nutrient source associated with the retinal pigment epithelium cells. Rod and cone densities (number per unit area of

Advancements in Computational Wind Engineering Workshop Report

December 13, 2023
Author(s)
Donald Scott, Jennifer Goupil, Melissa Burton, Catherine Gorle, Ahsan Kareem, Ted Stathopoulos, Bradley Young
In September 2022, the Structural Engineering Institute of the American Society of Civil Engineers commenced a project under National Institute of Standards and Technology Contract No. 133ND22PNB730391 to develop workshops on Advancement in Computational

Automated interpretation of firearm mark comparison results

December 13, 2023
Author(s)
Martin Baiker-Sorensen, Ivo Alberink, Laura Granell, Leen van der Ham, Erwin J.A.T. Mattijssen, Erich Smith, Johannes A. Soons, Peter Vergeer, Xiaoyu Alan Zheng
In this article an automated approach for interpretation of firearm mark comparison results is presented. First, similarity scores are derived for marks typically encountered on primers of fired cartridge cases: aperture shear striations as well as

Backdraft Experiments and Large Eddy Simulations in a scaled compartment

December 13, 2023
Author(s)
Marcos Vanella, Ryan Falkenstein-Smith, Thomas Cleary
An extensive set of backdraft experiments has been performed at the NIST National Fire Research Laboratory. These experiments were conducted in a reduced scale compartment, and are part of defining the conditions conducive to backdraft. Further, the
