Near Room‐Temperature Ferromagnetic Phase Achieved in 4d Ruthenate via Interfacial Ferrimagnetic Coupling and Octahedral Rotation Engineering

open access: yesAdvanced Science, EarlyView.
Transition metal oxides combining strong spin‐orbit coupling, near‐room‐temperature ferromagnetism, and high conductivity are rare. A Ca0.5Sr0.5RuO3 interfacial phase between LaMnO3 layers has all these features, high Tc, enhanced magnetization, and reduced coercivity.

Asymptotic behavior of a sixth-order Cahn-Hilliard system

open access: yes, 2013
Our aim in this paper is to study the asymptotic behavior, in terms of finite-dimensional attractors, of a sixth-order Cahn-Hilliard system. This system is based on a modification of the Ginzburg-Landau free energy proposed in [Torabi S., Lowengrub J ...

Generalized Phase Tailoring of Arbitrary Orthogonal Polarizations in Meta‐Structure with High‐Order Geometric Symmetry

open access: yesAdvanced Science, Volume 12, Issue 28, July 24, 2025.
A generalized methodology is proposed for Cm (m ≥ 3) meta‐structures to achieve independent phase control of arbitrary orthogonal polarizations. By integrating orientation tuning with structural tailoring, this approach extends spin‐based designs to polarization‐diverse wavefront engineering, enabling multi‐functional and high‐efficiency meta‐devices ...

Stirring Without Stirrers: Polymer Fouling‐Driven Mass Transport Unlocks Order‐of‐Magnitude Gain in Electrochemiluminescence

open access: yesAdvanced Science, EarlyView.
Strategic electrode fouling enhances mass transport, primarily through electrochemically actuated lateral density gradients. Engineered fouling induces flow velocities up to 0.4 cm s⁻¹ in otherwise quiescent systems. Sub‐millimeter plastic features boost local rates by up to 290%, while micrometer‐scale arrays yield a 30% net electrolysis gain ...

On the asymptotics of orthogonal polynomials on the curve with a denumerable mass points

open access: yesJournal of Numerical Analysis and Approximation Theory, 2007
We investigate the asymptotic behavior of orthogonal polynomials with respect to a measure of the type \(\sigma =\alpha +\gamma \), where \(\alpha \) is a measure concentrated on a rectifiable Jordan curve and \(\gamma \) is an infinite discrete measure.
