Structured, Shaped, or Printed Single‐Atom Catalysts and Their Applications

open access: yesAdvanced Functional Materials, EarlyView.
This paper reviews the design and use of structured single‐atom catalysts, which integrate porous architectures with the exceptional reactivity of isolated catalytic sites. It explores fabrication strategies, advanced characterization methods, and support materials that enhance thermal stability, mechanical robustness, and operational efficiency of ...

La liaison de l'adjectif sur le nom en français : morphologie, syntaxe, phonologie

open access: yesLinguistica, 2011
La liaison de l'adjectif sur le nom en français relève pour l'essentiel de la morphologie et de la syntaxe. Seules étudiées ici, les formes de liaison du masculin singulier (FLMS) constituent l'un des éléments du paradigme flexionnel de l'adjectif.

Ferrocene Derivatives Enable Ultrasensitive Perovskite Photodetectors with Enhanced Reverse Bias Stability

open access: yesAdvanced Functional Materials, EarlyView.
Novel ferrocene derivatives (e.g., FcPhc2) are used as an ultrathin layer hole‐blocking layer, reducing hole injection from the Ag contact. This results in an ultralow noise spectral density of 1.2 × 10−14 A Hz−1/2, and a high specific detectivity of 8.1 × 1012 Jones at −0.5 V.

Switching of Magnetic Order via Non‐Magnetic Al Addition in FeCoNiMnAlx Films

open access: yesAdvanced Functional Materials, EarlyView.
Non‐magnetic Al addition provides a sensitive handle to switch the magnetic order in high entropy FeCoNiMnAlx thin films via fcc to bcc phase transformation. Films with fcc structure exhibit a large exchange bias, while bcc films exhibit enhanced ferromagnetic properties, reflecting the magnetic ground state of Mn which switches from antiferromagnetic ...

High‐Entropy Liquid Metal Process for Transparent Ultrathin p‐Type Gallium Oxide

open access: yesAdvanced Functional Materials, EarlyView.
This work introduces a doping strategy for harvesting ultrathin Ga oxide layers using a multi‐elemental Ga‐based liquid metal alloy. The incorporation of trivalent In metal into the self‐limiting oxide formed on the alloy's surface is enabled by the existence of atomically dispersed Pt, Au, and Pd.

Engineering a Spin‐Orbit Bandgap in Graphene‐Tellurium Heterostructures

open access: yesAdvanced Functional Materials, EarlyView.
Tellurium intercalation in epitaxial graphene on Ir(111) enables the emergence of a spin–orbit‐induced bandgap with energy spin splitting. By combining STM, ARPES, spin‐resolved ARPES, and DFT, two structural phases are identified, both exhibiting tunable electronic doping.

Optical Control of the Thermal Conductivity in BaTiO3

open access: yesAdvanced Functional Materials, EarlyView.
Light‐driven manipulation of thermal conductivity in archetypal ferroelectric, BaTiO3, offers a novel and effective approach for the dynamical control of the heat flux, with potential applications in thermal management and phonon‐based logic. Abstract Achieving dynamic control over thermal conductivity remains a formidable challenge in condensed matter
