Core-shell and Egg-shell Zeolite Catalysts for Enhanced Hydrocarbon Processing

April 25, 2022
Author(s)
Thuy Tran Le, Kumari Shilpa, Choongsze Lee, Sungmin Han, Conan Weiland, Simon Bare, Paul Dauenhauer, Jeffrey Rimer
Developing structure-performance relationships with the underlying goal of optimizing known zeolite catalysts involves the manipulation of their physicochemical properties. Here, we systematically assessed the impact of mesoscopic gradients in acid site

Design and Experimentation Guidelines for DER's Emulation Testbed

April 23, 2022
Author(s)
Hasnae Bilil, Anfal Hathah, Abdella Battou
Due to the increasing integration of distributed energy resources (DERs) into the national grid, research is needed to understand high DER penetration in relation to grid reliability and stability. Emulation-based research is a viable option to consider

A Data Integration Framework for Additive Manufacturing Big Data Management

April 21, 2022
Author(s)
Milica Perisic, Dimitrije Milenkovic, Yan Lu, Albert T. Jones, Nenad Ivezic, Boonserm Kulvatunyou
Large amounts of data are generated throughout the entire, AM, part-development lifecycle. Data are generated by various functions within process monitoring, material characterization, equipment status, and part qualification. Hence, data integration and

Exceptional points in lossy media lead to deep polynomial wave penetration with spatially uniform power loss

April 21, 2022
Author(s)
Alexander Yulaev, Sangsik Kim, Qing Li, Daron Westly, Brian Roxworthy, Kartik Srinivasan, Vladimir Aksyuk
Waves entering a spatially uniform lossy medium typically undergo exponential decay, arising from either the energy loss of the Beer–Lambert–Bouguer transmission law or the evanescent penetration during reflection. Recently, exceptional point singularities

Hardware-Enabled Security: Policy-Based Governance in Trusted Container Platforms

April 20, 2022
Author(s)
Michael Bartock, Murugiah Souppaya, Haidong Xia, Raghu Yeluri, Uttam Shetty, Brandon Lum, Mariusz Sabath, Harmeet Singh, Alaa Youssef, Gosia Steinder, Yu Cao, Jayashree Ramanathan
In today's cloud data centers and edge computing, attack surfaces have significantly increased, cyber attacks are industrialized, and most security control implementations are not coherent or consistent. The foundation of any data center or edge computing

Surveying Practicing Firearm Examiners

April 20, 2022
Author(s)
Nicholas Scurich, Brandon Garrett, Robert M. Thompson
The comparison of discharged bullets and shell casings by firearm examiners is one of the most conducted forensic analyses. However, little is known empirically about how practicing firearm examiners view and conduct their work, the range of conclusions

Trusted Cloud: Security Practice Guide for VMware Hybrid Cloud Infrastructure as a Service (IaaS) Environments

April 20, 2022
Author(s)
Murugiah Souppaya, Michael Bartock, Karen Scarfone, Donna Dodson, Daniel Carroll, Gina Scinta, Hemma Prafullchandra, Harmeet Singh, Raghuram Yeluri, Tim Shea, Carlos Phoenix, Robert Masten, Paul Massis, Jason Malnar, Michael Dalton, Anthony Dukes, Brenda Swarts, Rajeev Ghandi, Laura Storey, Rocky Weber, Jeff Haskins
A cloud workload is an abstraction of the actual instance of a functional application that is virtualized or containerized to include compute, storage, and network resources. Organizations need to be able to monitor, track, apply, and enforce their

Quantum computing hardware for HEP algorithms and sensing

April 19, 2022
Author(s)
Corey Rae McRae
Quantum information science harnesses the principles of quantum mechanics to realize computational algorithms with complexities vastly intractable by current computer platforms. Typical applications range from quantum chemistry to optimization problems and

A Semi-Supervised Approach for Automatic Crystal Structure Classification

April 13, 2022
Author(s)
Satvik Lolla, Haotong Liang, Aaron Gilad Kusne, Ichiro Takeuchi, William D. Ratcliff
The structural solution problem can be a daunting and time consuming task. Especially in the presence of impurity phases, current methods such as indexing become more unstable. In this work, we apply the novel approach of semi-supervised learning towards

An Optical Investigation of the Heavy Fermion Normal State in Superconducting UTe 2

April 13, 2022
Author(s)
Sirak Mekonen, Chang-Jong Kang, Dipanjan Chaudhuri, David Barbalas, Sheng Ran, Gabriel Kotliar, Nicholas Butch, N. Armitage
The recently discovered superconductor, UTe2, has attracted immense scientific interest due to the experimental observations that suggest odd-parity superconductivity. It is believed that the material becomes a heavy-fermion metal at low temperatures

Antiferromagnetic VdW Phase at the Interface of Sputtered Topological Insulator/Ferromagnet Bi 2 Te 3 /Ni 80 Fe 2 0 Heterostructures

April 13, 2022
Author(s)
Nirjhar Bhattacharjee, Krishnamurthy Mahalingam, Adrian Fedorko, Valeria Lauter, Matthew Matzelle, Bahadur Singh, Alexander Grutter, Alexandria Will-Cole, Michael Page, Michael McConney, Robert Markiewicz, Arun Bansil, Don Heiman, Nian Sun
Magnetic ordering in topological insulators (TI) is crucial for breaking time-reversal symmetry (TRS) and thereby opening a gap in the topological surface states (TSSs) [1-6], which is the key for realizing useful topological properties such as the quantum

Chiral Spin Bobbers in Exchange-Coupled Hard-Soft Magnetic Bilayers

April 13, 2022

X. H. Zhang, T. R. Gao, L. Fang, S. Fackler, Julie A. Borchers, Brian Kirby, Brian B. Maranville, S. E. Lofland, A. T. N'Diaye, E. Arenholz, A. Ullah, J. Cui, R. Skomski, Ichiro Takeuchi
The spin structure of exchange-coupled MnBi:Co-Fe bilayers is investigated by X-ray magnetic circular dichroism (XMCD), polarized neutron reflectometry (PNR), and micromagnetic simu-lations. The purpose of the present research is two-fold. First, the

Demonstration that Einstein-Podolsky-Rosen Steering Requires More than One Bit of Faster-than-Light Information Transmission

Author(s)
Yu Xiang, Michael Mazurek, Joshua Bienfang, Michael Wayne, Carlos Abellan, Waldimar Amaya, Morgan Mitchell, Richard Mirin, Sae Woo Nam, Qiongyi He, Marty Stevens, Krister Shalm, Howard Wiseman
Schrödinger held that a local quantum system has some objectively real quantum state and no other (hidden) properties. He therefore took the Einstein-Podolsky-Rosen (EPR) phenomenon, which he generalized and called 'steering', to require nonlocal

Electrically Driven Exchange Bias via Solid State Magneto-Ionics
