Author(s)
Shouzhong Peng, Daoqian Zhu, Weixiang Li, Hao Wu, Alexander Grutter, Dustin A. Gilbert, Jiaqi Lu, Danrong Xiong, Wenlong Cai, Padraic Shafer, Kang L. Wang, Weisheng Zhao
Electrical manipulation of exchange bias and magnetization in antiferromagnet/ferromagnet thin films has been of great interest in recent years. Here, we experimentally demonstrate current-induced switching of exchange bias in perpendicularly magnetized

Methods for Characterization of Bioactivity Using Confocal Microscopy

December 1, 2020
Author(s)
Jirun Sun, Nancy Lin, Joy Dunkers, Sheng Lin-Gibson
One common tissue engineering approach for regenerating or replacing damaged tissues involves a porous polymeric scaffold. The scaffolds serve as the mechanical framework for cell attachment and growth, and generate an environment with features that span

Mission Critical Voice Quality of Experience Access Time Measurement Method Addendum

December 1, 2020
Author(s)
Chelsea Greene, Jesse Frey, Zainab O. Soetan, Jaden Pieper, Silas Thompson
Access time generally describes the time associated with the establishment of a talk path upon user request to speak and has been identified as a key component of quality of experience (QoE) in voice communications. The National Institute of Standards and

Temporal Memory with Magnetic Racetracks

Hamed Vakili, Mohammed N. Sakib, Samiran Ganguly, Mircea Stan, Matthew Daniels, Advait Madhavan, Mark D. Stiles, Avik W. Ghosh
Race logic is a relative timing code that represents information in a wavefront of digital edges on a set of wires in order to accelerate dynamic programming and machine learning algorithms. Skyrmions, bubbles, and domain walls are mobile magnetic

A low-swelling, polymeric mixed conductor operating in aqueous electrolytes

November 30, 2020
Author(s)
Lee Richter, Tommaso Nicolini, Jokubas Surgailis, Achileas Savva, Guillaume Wantz, Olivier Dautel, Georges Hadiziioannou, Natalie Stingelin
Organic mixed conductors find use in batteries, bioelectronics technologies, neuromorphic computing and sensing. While great progress has been achieved, polymer-based mixed conductors frequently experience significant volumetric changes during ion uptake

Numerical Evaluation of Advanced Laser Control Strategies Influence on Residual Stresses for Laser Powder Bed Fusion Systems

November 30, 2020
Author(s)
Carraturo Massimo, Brandon Lane, Ho Yeung, Stefan Kollmannsberger, Alessandro Reali, Ferdinando Auricchio
Process-dependent residual stresses are one of the main burdens to a wide spread adoption of laser powder bed fusion technology in industry. Residual stresses are directly influenced by process parameters, such as laser path, laser power, and speed. In

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

Runtime Verification of the ARIAC Competition: Can a Robot be Agile and Safe at the Same Time?

November 27, 2020
Author(s)
Angelo Ferrando, Zeid Kootbally, Pavlo Piliptchak, Rafael Cardoso, Craig I. Schlenoff, Michael Fisher
ARIAC (Agile Robotics for Industrial Automation Competition) is a robotic competition which aims to advance robotic agility in industry. Participants in this competition are required to implement a robot control system to overcome agility challenges in a

Intertwined Density Waves in a Metallic Nickelate

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
