Phase Change Material‐Driven Tunable Metasurface for Adaptive Terahertz Sensing and Communication in 6G Perceptive Networks

open access: yesAdvanced Functional Materials, EarlyView.
This study explores the benefits of metasurfaces made from functional materials, highlighting their ability to be adapted and improved for various high‐frequency applications, including communications and sensing. It first demonstrates the potential of these functional material‐based metasurfaces to advance the field of sub‐THz perceptive networks ...

Anomaly constraint on massless QCD and the role of Skyrmions in chiral symmetry breaking

open access: yesJournal of High Energy Physics, 2018
We discuss consequences of the ’t Hooft anomaly matching condition for Quantum Chromodynamics (QCD) with massless fundamental quarks. We derive the new discrete ’t Hooft anomaly of massless QCD for generic numbers of color N c and flavor N f , and an ...

Reconfigurable 3D Magnetic Nanoarchitectures

open access: yesAdvanced Functional Materials, EarlyView.
This experimental study confirms that 3D magnetic tetrapods grown by focused electron beam‐induced deposition exhibit sequential, controllable magnetization reversal in the individual nanowire legs. The magnetic state of the nanoarchitecture can be controlled individually, on‐demand, through a variation of the direction and magnitude of the applied ...

Quantifying Spatio‐Operational Heterogeneity in Electrochemical Devices via Operando Correlative Neutron and X‐Ray Tomography

open access: yesAdvanced Functional Materials, EarlyView.
Heterogeniety in electrochemical systems heavily influences device performance and durability. The study shows unique evidence of spatio‐operational heterogeneity in fuel cells via operando neutron and X‐ray tomography. Large variations in membrane thickness and hydration depend upon location and operating conditions, with implications on membrane ...

Ion and Solvent Dynamics in Charged 2D Clay Nanoslits with Unprecedented Ångström‐Precise Slit Height Control

open access: yesAdvanced Functional Materials, EarlyView.
The slit height of fluorohectorite 2D‐nanochannels is tuned with Å‐precision (2.4–250 Å). Slit‐height‐dependent ion and water mobilities are quantified by applying EIS, PFG‐NMR, and SFG‐NMR with MD simulations guiding interpretation. Diffuse properties are investigated with CP‐AFM, MD, and PB.

Discrete Symmetries Analysis and Exact Solutions of the Inviscid Burgers Equation

open access: yesDiscrete Dynamics in Nature and Society, 2012
We discuss the Lie point symmetries and discrete symmetries of the inviscid Burgers equation. By employing the Lie group method of infinitesimal transformations, symmetry reductions and similarity solutions of the governing equation are given.

Realization of Complex‐Shaped Magnetic Nanotubes with 3D Printing and Electrodeposition

open access: yesAdvanced Functional Materials, EarlyView.
Complex‐shaped magnetic nanotubes were fabricated by coating three‐dimensional nanoscaffolds fabricated with focused electron beam induced deposition with a magnetic coating via electrodeposition. X‐ray magnetic microscopy and simulations revealed an azimuthal magnetic configuration within the nanotubes and pinning of domain walls at curved vertices ...
