Electric-Current-Assisted Nucleation of Zero-Field Hopfion Rings. [PDF]

open access: yesAdv Mater
This work reports a novel and efficient nucleation protocol for 3D localized topological magnetic solitons‐hopfion rings in chiral magnets using pulsed electric currents. By using Lorentz transmission electron microscopy and topological analysis, we report characteristic features and extraordinary stability of hopfion rings in zero or inverted external

Diagonal flips in Hamiltonian triangulations on the projective plane

open access: yes, 2005
In this paper, we shall prove that any two triangulations on the projective plane with n vertices can be transformed into each other by at most 8n-26 diagonal flips, up to isotopy.

Strain Engineering of Magnetoresistance and Magnetic Anisotropy in CrSBr

open access: yesAdvanced Materials, EarlyView.
Biaxial compressive strain significantly enhances magnetoresistance and critical saturation fields in thin flakes of the 2D magnet CrSBr, along all three crystallographic axes. First‐principles calculations link these effects to strain‐induced increases in exchange interactions and magnetic anisotropy.

Cycles, Disjoint Spanning Trees and Orientations of Graphs

open access: yes, 2012
A graph G is hamiltonian-connected if any two of its vertices are connected by a Hamilton path (a path including every vertex of G); and G is s-hamiltonian-connected if the deletion of any vertex subset with at most s vertices results in a hamiltonian ...

Quantum Photothermal Self‐Monitoring Fiber Probes for In Vivo Photothermal Therapy

open access: yesAdvanced Science, EarlyView.
A miniaturized quantum photothermal fiber probe based on a metal/polymer/glass composite optoelectronic fiber that simultaneously guides lightwave and microwave was developed for the first time. The probe achieves enhanced photothermal conversion (13°C/mW, 25°C–120°C range) while providing real‐time self‐monitoring with 0.2°C thermal resolution at the ...

Field‐Frustrated Cooperative Distortions: Suppressing Jahn‐Teller Ordering via Microwave Annealing

open access: yesAdvanced Science, EarlyView.
Microwave annealing decouples local Jahn‐Teller distortions from long‐range cooperative ordering in CuFe2O4, stabilizing a metastable cubic phase that remains locally distorted yet globally symmetry‐frustrated. Synchrotron XRD, PDF, XPS, and in situ thermal cycling reveal how non‐equilibrium MW‐phonon interactions suppress cooperative orbital‐lattice ...

Multiferroic‐Centric Materials and Systems Engineering for Battery Applications: An Insight Into Mechanisms, Strategies, and Characterizations

open access: yesAdvanced Science, EarlyView.
Multiferroic order parameters – polarization, magnetization, and ferroelastic strain – are positioned as dynamic design variables for batteries. Their mechanistic roles, practical tuning through fabrication and external fields, and ferroic‐resolved characterization routes are unified into a closed‐loop framework, revealing how coupled ferroic responses

Bond Softening and Elastic Confinement of Monolithic Dense Binary Alloys for High Volumetric Capacity of K‐Ion Battery Anodes

open access: yesAngewandte Chemie, Volume 138, Issue 19, 4 May 2026.
Synergistically intrinsic‐extrinsic dual‐stabilization engineering to construct dense monolithic alloy architectures is proposed by integrating 2D binary alloy nanosheets into 3D elastic graphene networks. Such a dense monolithic anode achieves high volumetric and areal performance, enabling fast K+ transfer and superior structural recovery during ...
