Rotational Surfaces in Terms of Coordinate Finite Chen II-Type

open access: yesPan-American Journal of Mathematics
In this study, we first establish several formulae according to the first and second Beltrami operators. We discuss the class of surfaces of revolution in the 3-dimensional Euclidean space E3 without parabolic points, in which the position vector X ...

Dynamically Actuated Reconfigurable Topographical Surface Enables Active Control of Implant‐Associated Infections

open access: yesAdvanced Functional Materials, EarlyView.
A dynamically actuated reconfigurable topographical surface (DARTS) integrates contact‐mediated bactericidal nanotopography with programmable mechanical actuation to actively disrupt bacterial biofilms. Dynamic surface reconfiguration enhances bacterial killing and suppresses implant‐associated infections in vivo, providing a new strategy for active ...

On Godunov-type finite volume methods for seismic wave propagation

open access: yesDiscover Geoscience
The computational complexity of simulating seismic waves demands continual exploration of more efficient numerical methods. While Finite Volume methods are widely acclaimed for tackling general nonlinear hyperbolic (wave) problems, their application in ...

3-D Finite Element Model for Drum-Type HTS Dynamos

open access: yesIEEE Access
Continuous cylindrical stator high-temperature superconducting (HTS) dynamos, also known as drum-type HTS dynamos, are devices for contactless current injection, but their complex three-dimensional (3D) electromagnetic behaviour cannot be captured ...

Vector‐Field Control and Emergent Basal‐Plane Anisotropy of Magnetic Textures in Noncentrosymmetric (Fe0.63Ni0.3Pd0.07)3P

open access: yesAdvanced Functional Materials, EarlyView.
A field‐driven transition from chiral stripes to an achiral fan state is observed in a tetragonal magnet and linked to a temperature‐dependent rotation of the effective Dzyaloshinskii–Moriya interaction axis. This interplay generates pronounced in‐plane anisotropy and provides a new route for controlling chiral spin textures in noncentrosymmetric ...

Disorder‐Broadened Topological Hall Phase and Anomalous Hall Scaling in FeGe

open access: yesAdvanced Functional Materials, EarlyView.
By systematically introducing defects into FeGe via ion‐beam modification, we demonstrate that disorder broadens the temperature regime over which the topological Hall effect ‐ a signature of skyrmions or other chiral textures — appears, while also increasing its magnitude.

Bone‐Inspired Recyclable Composites for Damage‐Tolerant Circular Materials

open access: yesAdvanced Functional Materials, EarlyView.
Bone‐inspired architected composites are developed by combining osteon‐like reinforcements with a recyclable Elium thermoplastic matrix. The hierarchical architecture redirects cracks and promotes energy dissipation, while enabling recovery of intact, aligned, load‐bearing reinforcement units that retain their original stiffness, revealing a route ...

Unified Phase‐Field Framework for Antiferroelectric, Ferroelectric and Dielectric Phases: Application to HZO Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
HfxZr1−xO2${\rm Hf}_x{\rm Zr}_{1-x}{\rm O}_2$ offers CMOS‐compatible nanoscale ferroelectricity yet suffers from a high Ec${\rm E}_c$ demanding large operating voltages. A unified phase‐field framework spanning AFE/FE/DE phases shows how FE grains soften neighboring AFE grains over λ$\lambda$ ≈$\approx$ 22–37 nm.

Engineered Nanotopography to Modulate Growth and Signaling of Neuronal Networks

open access: yesAdvanced Functional Materials, EarlyView.
This study examines the interaction between neurons and nanoscale topographies on engineered substrates. Neurons cultured on nanowires, nanopillars and nanoneedles exhibit enhanced neurite outgrowth, form more organized neuronal circuits, and display improved synaptic connectivity, compared to flat substrates.
