Spin‐Polarized Antiferromagnets for Spintronics

open access: yesAdvanced Materials, EarlyView.
This review highlights recent advances in anomalous and spin transport phenomena in spin‐polarized antiferromagnets. Key effects—including the anomalous Hall, Nernst, and magneto‐optical effects—are discussed across various antiferromagnetic platforms.

GelMA/AgNWs Hydrogel Combined with Electrical Stimulation Effectively Promotes Skin Wound Healing

open access: yesAdvanced Materials Interfaces, EarlyView.
The doped AgNWs in GelMA hydrogel prevent the wound from being infected and introduce the electrical field into the wound region. COMSOL simulation guides the introduced electric field to be conducive to promoting cell migration and proliferation. Thus, the GelMA/AgNWs hydrogel combined with ES effectively accelerated the healing process of skin wounds.

Maximum Principles for Dynamic Equations on Time Scales and Their Applications

open access: yesJournal of Applied Mathematics, 2014
We consider the second dynamic operators of elliptic type on time scales. We establish basic generalized maximum principles and apply them to obtain weak comparison principle for second dynamic elliptic operators and to obtain the uniqueness of Dirichlet

Emergent Ferromagnetism at LaFeO3/SrTiO3 Interface Arising from a Strain‐Induced Spin‐State Transition

open access: yesAdvanced Materials Interfaces, EarlyView.
Strain at the LaFeO3/SrTiO3 interface induces spin‐state disproportionation, creating a checkerboard pattern of low‐ and high‐spin Fe3+ ions. This unusual configuration leads to interfacial ferromagnetism in an otherwise antiferromagnetic insulator. Using electron microscopy, spectroscopy, and density functional theory, this work reveals a new route to

Exploring the Role of Stent Strut Geometry in Cellular Behavior: An In Vitro Chip Model to Understand In‐Stent Restenosis

open access: yesAdvanced Materials Interfaces, EarlyView.
An engineered in vitro platform mimicking stent strut cross‐sectional shapes reveals how geometry influences cell behavior. Sharp‐cornered geometries promote cell proliferation and matrix alignment, while rounded shapes reduce these effects. The findings align with clinical outcomes and suggest intracellular tension as a key driver, offering a ...

Operatori ellittici massiminimanti

open access: yesLe Matematiche, 1996
In the theory of second order elliptic equations, in non divergence form, two non linear elliptic operators, which are non convex with respect to the second derivatives, are studied.
