A Soot Deposition Gauge for Fire Measurements

March 12, 2018
Author(s)
Amy E. Mensch, Thomas G. Cleary
The goal of this exploratory project is to demonstrate the feasibility of a conductometric measurement to determine the time-resolved soot deposition on surfaces in fire environments. Quantitative soot deposition data enabled by this measurement method is

Approaches to the Optimal Nonlinear Analysis of Microcalorimeter Pulses

March 8, 2018
Author(s)
Joseph W. Fowler, Christine G. Pappas, Bradley K. Alpert, William B. Doriese, Galen C. O'Neil, Joel N. Ullom, Daniel S. Swetz
We consider how to analyze microcalorimeter pulses for quantities that are nonlinear in the data, while preserving the signal-to-noise advantages of linear optimal filtering. We apply the approach to compute the electrothermal feedback energy deficit (the

Synchrotron Methods for Flexible Hybrid Electronics Industrial Recommendations on Interagency (DoC-DoD-DoE) Partnerships to Address Measurement Challenges Hindering the Flexible Hybrid Electronics Manufacturing Ecosystem

February 12, 2018
Author(s)
Christopher L. Soles, Richard A. Vaia, Ronald Pindak
The round-table participants concluded that facilities at NSLS-II provide immediate opportunities to address some of the critical processing and measurement challenges that are blocking the path towards a sustainable US-centric Flexible Hybrid Electronic

Parametric resonance in linear microresonators using analog feedback

January 21, 2018
Author(s)
Jason J. Gorman, Vikrant J. Gokhale
This paper reports on the design and implementation of an analog feedback controller for generating parametric resonance in linear microresonators that do not intrinsically demonstrate this phenomenon. It is shown that the controller produces a fundamental

Dependence of transition width on current and critical current in transition-edge sensors

December 7, 2017
Author(s)
Kelsey M. Morgan, Christine G. Pappas, Douglas A. Bennett, Johnathon D. Gard, James P. Hays-Wehle, Gene C. Hilton, Carl D. Reintsema, Daniel R. Schmidt, Joel N. Ullom, Daniel S. Swetz
If transition-edge sensor (TES) X-ray detectors are to be useful in photon-rich environments,they must maintain high resolving power when pulse durations are engineered to be short, which is usually accomplished by increasing the thermal conductance (G)to

Advanced Electrical Power System Sensors Workshop Report

November 13, 2017
Author(s)
Allen R. Goldstein
The objective of the Advanced Electrical Power Sensors Workshop was to provide input into planning processes being undertaken by the National Institute of Standards and Technology (NIST), Department of Energy (DOE), and the Grid Modernization Laboratory

Nanowire Aptasensors for Electrochemical Detection of Cell-Secreted Cytokines

October 9, 2017
Author(s)
Ying Liu, Ali Rahimian, Sergiy Krylyuk, Tam Vu, Bruno Crulhas, Gulnaz Stybayeva, Dong-Sik Shin, Albert Davydov, Alexander Revzin, Meruyert Imanbekova
Cytokines are small proteins secreted by immune cells in response to pathogens/infections; therefore these proteins can be used in diagnosing infectious diseases. For example, release of a cytokine interferon (IFN)-γ from T-cells is used for blood-based

Toward 3D printed hydrogen storage materials made with ABS-MOF composites

September 26, 2017
Author(s)
Megan C. Kreider, Zeeshan Ahmed, Makfir Sefa, James A. Fedchak, Julia Scherschligt, Michael Bible, Nikolai Klimov, Bharath Natarajan, Hartings Mathew
The push to advance efficient, renewable, and clean energy sources has brought with it an effort to generate materials that are capable of storing hydrogen. Metal-organic framework materials (MOFs) have been the focus of many such studies as they are

3.5 GHz Environmental Sensing Capability Detection Thresholds and Deployment

September 1, 2017
Author(s)
Thao Nguyen, Anirudha Sahoo, Michael R. Souryal, Timothy Hall
Spectrum sharing in the 3.5~GHz band between commercial and government users along U.S. coastal areas depends on an Environmental Sensing Capability (ESC)---that is, a network of radio frequency sensors and a decision system---to detect the presence of
