Far-field interference of a neutron white beam and the applications to noninvasive phase-contrast imaging

April 21, 2021
Author(s)
Michael G. Huber, Daniel S. Hussey, Muhammad D. Arif, David L. Jacobson, Jacob LaManna, Wakana Ueno, Han Wen, Dmitry Pushin, Dusan Sarenac, David Cory, Houxun Miao, Takenao Shinohara, Joseph Parker
The phenomenon of interference plays a crucial role in the field of precision measurement science. Waveparticle duality has expanded the well-known interference effects of electromagnetic waves to massive particles. The majority of the wave-particle

Thermal And Visual Observation Of Water And Acetone Oscillating Heat Pipes

April 21, 2021
Author(s)
Daniel S. Hussey, David L. Jacobson, Hongbin Ma, R. A. Winholtz, Corey Wilson, Corey Borgmeyer
Identical oscillating heat pipes (OHP) charged separately with water and acetone were observed thermally and visually at varying condenser temperatures and heat inputs. Neutron radiography allowed visualization of hydrogen rich liquid water and acetone

Thick Sintered Electrode Lithium-Ion Battery Discharge Simulations: Incorporating Lithiation-Dependent Electronic Conductivity and Lithiation Gradient due to Charge Cycle

April 21, 2021
Author(s)
Daniel S. Hussey, Jacob LaManna, David L. Jacobson, Gary Koenig
In efforts to increase the energy density of lithium-ion batteries, researchers have attempted to both increase the thickness of battery electrodes and increase the relative fractions of active material. One system that has both of these attributes are

Three Phase-Grating Moire Neutron Interferometer for Large InterferometerArea Applications

April 21, 2021
Author(s)
Michael G. Huber, D. Sarenac, D. A. Pushin, Houxun Miao, Daniel S. Hussey, D G. Cory, Muhammad D. Arif, David L. Jacobson, Jacob LaManna, Ben Heacock
We demonstrate a three phase-grating neutron interferometer as a robust candidate for large area interferometry applications and characterization of materials. This novel far- eld moire technique allows for broad wavelength acceptance and relaxed

Electrolyte Layer Gas Triggers Cathode Potential Instability in CO2 Electrolyzers

February 1, 2021
Author(s)
Kevin Krause, Jason K. Lee, ChungHyuk Lee, Hisan W. Shafaque, Pascal J. Kim, Kieran F. Fahy, Pranay Shrestha, Jacob LaManna, Elias Baltic, David Jacobson, Daniel Hussey, Aimy Bazylak
Electrolytic carbon dioxide (CO2) reduction is becoming increasingly promising for managing anthropogenic CO2 emissions; however, issues related to unstable performance and ineffective gas management are still not fully accounted for in the field. Here, we

Water Migration and Swelling in Engineered Barrier Materials for Radioactive Waste Disposal

January 25, 2021
Author(s)
Joanna McFarlane, Lawrence M Anovitz, Michael C. Cheshire, Victoria H. DiStefano, Hassina Z. Bilheux, Jean-Christophe Bilheux, Luke L. Daemen, Richard E. Hale, Ronald L. Howard, A. J. Ramirez-Cuesta, Louis J. Santodonato, Markus Bleuel, Daniel S. Hussey, David L. Jacobson, Jacob LaManna, Edmund Perfect, Logan Qualls
Deep underground repositories are needed to isolate radioactive waste from the biosphere. Bentonite is an integral component of many multibarrier repository systems. Information on the hydraulic behavior of bentonite is needed for modeling the long-term

The interactive effect of heat and mass transport on water condensation in the gas diffusion layer of a proton exchange membrane fuel cell

December 31, 2020
Author(s)
Po-Ya A. Chuang, Md A. Rahman, Felipe Mojica, Daniel S. Hussey, David L. Jacobson, Jacob LaManna
Despite recent advancement in fuel cell technology, significant challenges remain in achieving high power density operation to meet the stringent targets of performance, durability and cost. This is due to the lack of fundamental understanding in
