Evaluating Dielectric Properties for Semicrystalline Thermoplastics to Analyze the Thermal and Rheological Properties in Laser‐Based Powder Bed Fusion of Plastics

open access: yesAdvanced Engineering Materials, EarlyView.
This study aims to establish a link between the dielectric properties of polyamide 12 (PA12) and its thermal and rheological properties using dielectric analysis (DEA). A standardized methodology is introduced to determine melting and crystallization temperatures.

Holographic corrections to meson scattering amplitudes

open access: yesNuclear Physics B, 2017
We compute meson scattering amplitudes using the holographic duality between confining gauge theories and string theory, in order to consider holographic corrections to the Veneziano amplitude and associated higher-point functions.

Mechanical Properties of Different Austenitic High‐Nitrogen Steel Grades Produced by Powder Mixtures

open access: yesAdvanced Engineering Materials, EarlyView.
The effect of nitrogen content on the mechanical properties of austenitic stainless steels is investigated using tailored powder metallurgical processing. Different PM routes, including additive manufacturing, enable controlled nitrogen uptake and complex geometries.

In Situ Formation of a Melt‐Solid Interface Toward Stable Oxygen Reduction in Protonic Ceramic Fuel Cells

open access: yesAdvanced Functional Materials, Volume 35, Issue 12, March 18, 2025.
Protonic ceramic fuel cells offer a promising route to generate power efficiently but face critical challenges in achieving industrially viable activity and stability at their cathodes in CO2‐containing air. This report proposes a new cathode material design strategy to enable the cathode to be both catalytically active and CO2 tolerant through the ...

Evidence of Long‐Range Dzyaloshinskii–Moriya Interaction at Ferrimagnetic Insulator/Nonmagnetic Metal Interfaces

open access: yesAdvanced Functional Materials, EarlyView.
This study demonstrates that in sputter‐deposited Tb3Fe5O12 (TbIG)/nonmagnetic metal (NM) heterostructures, the interfacial Dzyaloshinskii–Moriya Interaction (DMI) originates at the TbIG/NM interface. Furthermore, measurements suggest a significant interfacial DMI arising from a second non‐local interface, created by inserting a Cu spacer layer between

Ultra‐Fast Non‐Volatile Resistive Switching Devices with Over 512 Distinct and Stable Levels for Memory and Neuromorphic Computing

open access: yesAdvanced Functional Materials, EarlyView.
A materials and device design concept that comprises a self‐assembled ultra‐thin epitaxial ion‐transporting layer, an amorphous oxide overcoat oxygen‐blocking layer, and a partial filament formed during an electroforming step is proposed for low‐current multilevel resistive switching devices.

Splitting CEGM amplitudes

open access: yesJournal of High Energy Physics
The CEGM formalism offers a general framework for scattering amplitudes, which rests on Grassmannians, moduli spaces and tropical geometry. The physical implications of this generalization are still to be understood.

Gluon Scattering in Deformed N=4 SYM

open access: yes, 2008
We consider gluon and gluino scattering amplitudes in large N beta-deformed N=4 SYM with real beta. A direct inspection of the planar diagrams shows that the scattering amplitudes to all orders in perturbation theory are the same as in the undeformed N=4
