Investigating Soot Generated from Engineered Building Materials

November 27, 2020
Author(s)
Samuel L. Manzello, Sayaka Suzuki
Large outdoor fires are of concern all over the world. While fire spread processes are noted for their immediate destruction and loss of life, the generation of particulate matter from the combustion of both vegetative and structural fuels in the event of

RULE MODEL FOR SELECTING DIMENSIONAL MEASUREMENT EQUIPMENT IN INSPECTION PLANNING

November 27, 2020
Author(s)
Shaw C. Feng, John A. Horst, Allison Barnard Feeney, Albert T. Jones
Process uncertainty can have negative impact on the part quality and is critical to safety and performance of products. Those impacts are manifested in the dimensional measurement uncertainty associated with those parts and products. To minimize the

Junjie Zhang, D. Phelan, A. S. Botana, Yu-Sheng Chen, Hong Zheng, M. Krogstad, Suyin G. Wang, Yiming Qiu, Jose Rodriguez Rivera, R. Osborn, S. Rosenkranz, M. R. Norman, J. F. Mitchell
Nickelates are a rich class of materials, ranging from insulating magnets to superconductors. But for stoichiometric materials, insulating behavior is the norm, as for most late transition metal oxides. Notable exceptions are the 3D perovskite LaNiO 3, an

Six-sigma Quality Management of Additive Manufacturing

November 26, 2020
Author(s)
Yan Lu, Hui Yang, Paul Witherell
Quality is a key determinant in deploying new processes, products or services, and influences the adoption of emerging manufacturing technologies. The advent of additive manufacturing (AM) as a manufacturing process has the potential to revolutionize a

Boosting Membrane Hydration for High Current Densities in Membrane Electrode Assembly CO2 Electrolysis

November 25, 2020
Author(s)
Hisan W. Shafaque, ChungHyuk Lee, Kieran F. Fahy, Jason K. Lee, Jacob LaManna, Eli Baltic, Daniel S. Hussey, David L. Jacobson, Aimy Bazylak
Despite the advantages of CO2 electrolyzers, efficiency losses due to mass and ionic transport across the membrane electrode assembly (MEA) are critical bottlenecks for commercial-scale implementation. In this study, more efficient electrolysis of CO2 was

Materials Combining Asymmetric Pore Structures with Well-Defined Mesoporosity for Energy Storage and Conversion

November 25, 2020
Author(s)
Sarah Hesse, Kevin Fritz, Peter A. Beaucage, R. Paxton Thedford, Fei Yu, Francis Disalvo, Jin Suntivich, Ulrich Wiesner
Porous materials design often faces a trade-off between the requirements of high internal surface area and high reagent flux. Inorganic materials with asymmetric/hierarchical pore structures or well-defined mesopores have been tested to overcome this trade

Staggered spin Hall conductivity

November 25, 2020
Author(s)
Fei Xue, Paul M. Haney
The intrinsic spin Hall effect plays an important role in spintronics applications, such as spin-orbit torque-based memory. The bulk space group symmetry determines the form of the bulk spin current conductivity tensor. This paper considers materials for

Study of the Reactions of OH with HCl, HBr, and HI between 298 K and 460 K.

November 24, 2020
Author(s)
Vladimir L. Orkin, Victor Khamaganov, Igor Larin
The reactions between OH radicals and hydrogen halides (HCl, HBr, HI) have been studied between 298 K to 460 K by using a discharge flow – electron paramagnetic resonance technique. The rate constants at room temperature were found to be kHCl(298 K) = (7.9
