THz-Frequency Spin-Hall Auto-Oscillator Based on a Canted Antiferromagnet

open access: yes, 2017
We propose a design of a THz-frequency signal generator based on a layered structure consisting of a current-driven platinum (Pt) layer and a layer of an antiferromagnet (AFM) with easy-plane anisotropy, where the magnetization vectors of the AFM ...

Metal‐Organic Framework Embedded Electrospun Fibrous Membranes‐Based Hybrid Nanogenerators with Hierarchical Modified Polyamide Films for Mechanical Energy Harvesting and IoT Applications

open access: yesAdvanced Functional Materials, EarlyView.
Hybrid nanogenerator (HNG) based on a zinc‐metal‐organic framework‐loaded fibrous film integrated with a hierarchically modified nylon film having micropatterns and micropores is fabricated via an electrospinning technique, and its electrical properties are optimized. The HNGs are incorporated into wearable garments and automobile systems for practical

Stratégies des marques face à leur appropriation par un artiste : Analyse réalisée à partir d’œuvres appartenant au mouvement du pop art et à ses héritiers

open access: yesK@iros
This research focuses on the rapprochement between commercial world of brands and that of art, two worlds that are a priori distinct. Indeed, essentially since the 20th century, the artistic sphere tends to be more and more intertwined with brands that ...

6.4 GHz Acoustic Sensor for In-situ Monitoring of AFM Tip Wear [PDF]

open access: yes, 2011
This paper demonstrates an acoustic sensor that can resolve atomic force microscopy (AFM) tip blunting with a frequency sensitivity of 0.007%. The AFM tip is fabricated on a thin film piezoelectric aluminum nitride (AlN) membrane that is excited as a ...

Multi-step atomic reaction enhanced by an atomic force microscope probe on Si(111) and Ge(111) surfaces

open access: yes, 2016
We present first-principles total-energy electronic-structure calculations that provide the microscopic mechanism of the adatom interchange reaction on the Sn- and Pb-covered Ge(111)-(2x8) and the Sb-covered Si(111)-(7x7) surfaces with and without the ...

Flexibility and Dynamicity Enhances and Controls Supramolecular Self‐Assembly of Zinc(II) Metallogels

open access: yesAdvanced Functional Materials, EarlyView.
Zinc(II) coordination complexes with tunable aryloxy‐imine ligands exhibit controllable supramolecular self‐assembly into hierarchical fibrous structures. Coordination‐driven stacking, not π–π interactions, enables gelation, dynamic assembly/disassembly, and enhanced nanomechanical properties.

Magnetic structure of the antiferromagnetic half-Heusler compound NdBiPt

open access: yes, 2015
We present results of single crystal neutron diffraction experiments on the rare-earth, half-Heusler antiferromagnet (AFM) NdBiPt. This compound exhibits an AFM phase transition at $T_{\mathrm N}=2.18$~K with an ordered moment of $1.78(9)$~$\mu_{\mathrm ...

FeDSNP‐Pa Nanoassemblies: A Triple‐Action Therapeutic Strategy Targeting Oxidative Stress, Inflammation, and Pyroptosis for Retinal Ganglion Cell Protection in Glaucoma

open access: yesAdvanced Functional Materials, EarlyView.
FeDSNP‐Pa, a metallized nanoparticle loaded with sodium pyruvate (Pa), exerts triple therapeutic effects by scavenging reactive oxygen species (ROS), suppressing inflammatory responses, and inhibiting pyroptosis signaling pathways. This multifunctional neuroprotective strategy protecting retinal ganglion cells (RGCs) from elevated intraocular pressure ...

Competition of Superconductivity and Antiferromagnetism in a d-Wave Vortex Lattice

open access: yes, 2002
The d-wave vortex lattice state is studied within the framework of Bogoliubov-de Gennes (BdG) mean field theory. We allow antiferromagnetic (AFM) order to develop self-consistently along with d-wave singlet superconducting (dSC) order in response to an ...

Tuning the Dielectric Properties of Individual Clay Nanosheets by Interlayer Composition: Toward Nano‐Electret Materials

open access: yesAdvanced Functional Materials, EarlyView.
The dielectric properties of clays are studied on the level of individual monolayers and functional double stacks. The material breakdown characteristics and charge storage performance are analyzed. For illustration, a defined charge pattern representing a cuneiform character is produced, written into a microscopic clay tile, referencing the origins of
