Fractional Skyrmion Tubes in Chiral‐Interfaced 3D Magnetic Nanowires

open access: yesAdvanced Functional Materials, EarlyView.
In chiral 3D helical magnetic nanowires, the coupling between the geometric and magnetic chirality provides a way to create topological spin states like vortex tubes. Here, it is demonstrated how the breaking of this coupling in interfaced 3D nanowires of opposite chirality leads to even more complex topological spin states, such as fractional ...

Fast Neutron Detector Based on Hybrid 2D Perovskite Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
This work presents the direct detection of fast neutrons using flexible hybrid 2D perovskite (PEA2PbBr4) thin‐film detectors. Thanks to their high low‐Z elements content and good charge transport, these materials enable efficient neutron detection. The thin film configuration allowed the operation at low voltage, and offer scalability, flexibility, and

La sociologie urbaine dans le contexte français

open access: yesSociologies, 2012
This synthesis begins by recalling some outlines of a story whose the contemporary French urban sociology is to some extent the heir: an emergence which took place later than in other countries, a recurrent questioning about the object itself, a leading ...

On k-transversals

open access: yesJournal of Combinatorial Theory, Series A, 1987
One of the main results of this paper is Theorem 3: If H is a family of infinite sets then H has a k-transversal if and only if it has a transversal.

Perfusable Brain Microvascular Network‐On‐Chip Model to Study Flavivirus NS1‐Induced Endothelial Dysfunction

open access: yesAdvanced Functional Materials, EarlyView.
This study presents a microfluidic brain microvascular network‐on‐chip (BMVasChip) to investigate endothelial barrier dysfunction caused by flavivirus non‐structural protein 1 (NS1), including virus‐ and time‐dependent vascular damage, leakiness, and dysfunction.

Anionic Citrate‐Based 3D‐Printed Scaffolds for Tunable and Sustained Orthobiologic Delivery to Enhance Tissue Regeneration

open access: yesAdvanced Functional Materials, EarlyView.
A potent anionic citric acid‐based 3D‐printed scaffold is developed for the sustained and controlled release of orthobiologics to enhance orthopedic therapeutic efficacy. Comprehensive in vivo studies demonstrated effective bone fusion and high safety at a low dose of BMP‐2 delivered by the system, establishing it as a promising platform for safe ...
