Influence of Substrate Moisture State and Roughness on Interface Microstructure and Bond Strength: Slant Shear vs. Direct Tension Testing

December 8, 2017
Author(s)
Dale P. Bentz, Igor de la Varga, Jose Munoz, Robert Spragg, Benjamin Graybeal, Daniel S. Hussey, David L. Jacobson, Scott Z. Jones, Jacob M. LaManna
There are conflicting views in the literature concerning the optimum moisture state for an existing substrate prior to the application of a repair material. Both saturated-surface-dry (SSD) and dry substrates have been found to be preferable to the other

Neutron and X-ray Tomography (NeXT) system for simultaneous, dual modality tomography

November 27, 2017
Author(s)
Jacob M. LaManna, Daniel S. Hussey, Elias M. Baltic, David L. Jacobson
Dual mode tomography offers the potential of improved estimation of the composition of a sample from the complimentary of the interaction of the two probes with the sample. We have developed a simultaneous neutron and 90 keV X-ray tomography system that is

Studying Water and Solute Transport through Desalination Membranes via Neutron Radiography

October 25, 2017
Author(s)
Devin L. Shaffer, Jacob M. LaManna, David L. Jacobson, Daniel S. Hussey, Menachem Elimelech, Edwin P. Chan
Neutron radiography, a non-destructive imaging technique, is applied to study water and solute transport through desalination membranes. Specifically, we use neutron radiography to quantify lithium chloride draw solute concentrations across a thin-film

Simultaneous Neutron and X-Ray Imaging of 3D Kerogen and Fracture Structure in Shales

June 17, 2017
Author(s)
Wei-Shan NMN Chiang, Jacob M LaManna, Daniel S. Hussey, David L. Jacobson, Yun Liu, Jilin Zhang, Daniel T. Georgi, Jin-hong Chen
Hydrocarbon production from shales using horizontal drilling and hydraulic fracturing has been the key development in US energy industry in the past decade and has now become more important globally. Nevertheless, many fundamental problems related to the

A pseudo-3D model to investigate heat and water transport in large area PEM fuel cells - Part 2: Application on an automotive driving cycle

September 14, 2016
Author(s)
Daniel S. Hussey, J-P Poirot-Crouvezier, M. Chandesris, S. Rosini, David L. Jacobson, Jacob M. LaManna, A. Morin, Y. Bultel
In this work, the pseudo-3D multiphysics model introduced in Part 1 of this two-part series of papers is used to investigate heat and water transport in a proton exchange membrane fuel cell designed for an automotive application. The main advantage of the
