Author(s)
Huairuo Zhang, Albert Davydov, Shafin Hamid, Eric Pop, Asir Khan
Spiking neural networks (SNN) with Ge2Sb2Te5 (GST) based phase change memory (PCM) synaptic devices are promising for edge applications. However, from a de-vice standpoint, the performance of such SNN is often con-strained by the abrupt depression

Probing Intrinsic Magnetization Dynamics of the Y3Fe5O12/Bi2Te3 Interface at Low Temperature

A. R. Will-Cole, Valeria Lauter, Alexander Grutter, Carsten Dubs, David Lidsky, Morris Lindner, Timmy Reimann, Nirjhar Bhattacharjee, Tzu-Ming Lu, Peter Sharma, Nichole Valdez, Charles Pearce, Todd Monson, Matthew Matzelle, Arun Bansil, Don Heiman, Nian Sun
Topological insulator–magnetic insulator (TI–MI) heterostructures hold significant promise in the field of spintronics, offering the potential for manipulating magnetization through topological surface state–enabled spin-orbit torque. However, many TI–MI

Detailed Dynamics of a Moving Magnetic Skyrmion Lattice in MnSi Observed Small-Angle Neutron Scattering under an Alternating Electric Current Flow

D. Okuyama, M. Bleuel, Qiang Ye, Jeffery Krzywon, N. Nagaosa, A. Kikkawa, Y. Taguchi, Y. Tokura, J. Reim, Y. Nambu, T. Sato
Lattice formation of swirling textures is ubiquitous in solid-state materials, such as a magnetic skyrmion lattice in chiral magnets. In the magnetic skyrmion lattices, their moving states and dynamics under external perturbations are still unrevealed

Reverse Separation of Carbon Dioxide and Acetylene in Two Isostructural Copper Pyridine-Carboxylate Frameworks

July 21, 2024
Author(s)
Jing-Hong Li, You-Wei Gan, Jun-Xian Chen, Rui-Biao Lin, Yisi Yang, Hui Wu, Wei Zhou, Banglin Chen, Xiao-Ming Chen
Separating acetylene from carbon dioxide is important but highly challenging due to their similar molecular shapes and physical properties. Adsorptive separation of carbon dioxide from acetylene can directly produce pure acetylene but is hardly realized

Effects of hydrogen on the evolution of 4130 steel microstructure as a result of tensile loading

July 12, 2024
Author(s)
Zack Buck, May Ling Martin, Damian Lauria, Jason Killgore, Peter Bradley, Yan Chen, Ke An, Matthew Connolly
Neutron diffraction and Scanning Kelvin Probe Force Microscopy (SKPFM) were used to study the evolution of lattice strain, dislocation density, and phase partitioning of a ferrite/martensite pressure vessel steel (AISI 4130) that resulted from tensile

Entanglement kinetics in polymer melts are chemically specific

July 3, 2024
Author(s)
Benjamin Dolata
We investigate the universality of entanglement kinetics in polymer melts. We compare predictions of a recently developed constitutive equation for disentanglement to molecular dynamics simulations of both united-atom polyethylene and Kremer-Grest models
