Efficient Magnetization Switching Driven by Orbital Torque in Light 3d Transition‐Metal Nitrides

open access: yesAdvanced Functional Materials, EarlyView.
Efficient magnetization switching is demonstrated through orbital torque generated from light 3d transition‐metal nitride. Transition‐metal nitrides are established as effective sources of orbital angular momentum for current‐induced switching, highlighting their potential for low‐power next‐generation orbitronic devices beyond conventional heavy‐metal‐

Estimating the time and angle of arrivals in mobile communications

open access: yes, 2013
Dans ce projet, nous présentons une méthode nouvelle et précise d’estimation de la direction et des délais d’arrivée dans un environnement à trajets multiples, à des fins d’estimation de canal. Récemment, les méthodes de super-résolution ont été largement utilisées pour l’estimation à haute-résolution de la direction d’arrivée (DOA) ou de la différence

Modulation of Surface‐Associated Transport in (Bi1‐xSbx)2Te3 via Battery‐ Inspired Solid‐State Iontronic Gating

open access: yesAdvanced Functional Materials, EarlyView.
Iontronic gating in a battery‐inspired device modulates the relative weight of surface‐associated and bulk‐like transport fingerprints in (Bi1‐xSbx)2Te3, resulting in phenomenological valve‐like transport behavior. The strongest WAL‐associated coherent transport signatures emerge near the transport‐defined carrier compensation regime at ultra‐low gate ...

Scalable Fabrication of Thermally Reconfigurable Ge Metasurfaces Using Stencil Lithography for Mid‐Infrared Molecular Fingerprinting

open access: yesAdvanced Functional Materials, EarlyView.
Scalable stencil lithography enables resist‐free fabrication of high‐index Ge metasurfaces for mid‐infrared molecular fingerprinting. Reversible thermo‐optic tuning provides post‐fabrication spectral control for precise resonance–vibration mode alignment, enabling enhanced molecular fingerprinting of microplastic particles.

Integrated Multiband Smart Windows From UV to LWIR Based on Molecularly Engineered Thermochromic Hydrogels

open access: yesAdvanced Functional Materials, EarlyView.
A multiband smart window integrating a thermochromic poly (EEEA‐co‐NIPAM) hydrogel with functional layers, enabling dynamic VIS‐NIR solar modulation alongside UV shielding and low LWIR emissivity. The polymer network forms hydrogen‐bonding interactions, promoting chain collapse above a reduced lower critical solution temperature, and accelerating the ...

Hydrogel‐Based Method for High‐Resolution Measurements of Contact Mechanics in Rapid Biological Adhesives: A Case Study in Cuttlefish Tentacle Strikes

open access: yesAdvanced Functional Materials, EarlyView.
Cuttlefish and squid can catch their prey within milliseconds using specialized tentacles and suckers. The physics of how the suckers can attach so quickly has remained a mystery given the technical challenges of studying them in vivo. In this publication, we develop a hydrogel that retains imprints of the suckers in order to estimate the forces they ...
