Advanced Functional Materials, EarlyView.We use scanning nitrogen vacancy magnetometry to directly image the weak in‐plane magnetic moments in mixed phase BiFeO3 at the nanoscale and quantify the local magnetic moments to be 18.8±2.0 μB/nm2 in the rhombohedral‐like phase and 1.5±0.6 μB/nm2 in the well‐known non‐magnetic tetragonal‐like phase.

Unraveling the Electronic Structure of Silicon Vacancy Centers in 4H‐SiC
Advanced Functional Materials, EarlyView.The electronic structure of the silicon vacancy in 4H‐SiC is probed via transient absorption spectroscopy, uncovering previously inaccessible excited states of the quartet and doublet spin channels, including the V2' transition. In combination with theoretical analysis, a comprehensive picture of the electronic structure is established.

Chiral Phase Change Nanomaterials
Advanced Functional Materials, EarlyView.This work demonstrates reversible, non‐volatile phase transitions in chiral Ge2${\rm Ge}_2$Sb2${\rm Sb}_2$Te5${\rm Te}_5$ (GST) nanohelices for high‐speed optical modulation of chirality and dynamic control of the state of polarization (SOP). The chiral nanostructures are fabricated using a highly directional, wafer‐scale physical vapor deposition ...

Particle-induced x-ray emission spectrometry of size-fractionated atmospheric aerosols [PDF]
, 2002 Atmospheric aerosol samples were collected with a stacked filter unit (SFU), which separates the aerosol into a coarse (2-10 µm aerodynamic diameter (AD)) and a fine (< 2 µm AD) size fraction. The samples were analysed by particle-induced x-ray emission (PIXE) spectrometry.

Advanced Functional Materials, EarlyView.Mucoadhesive amphiphilic block and statistical copolymers were synthesized via Reversible Addition–Fragmentation Chain Transfer polymerization from bio‐sourced myrcene and polyethylene glycol methacrylate. The resulting polymers exhibit narrow molar‐mass distributions, high regioselectivity, well‐defined microstructures, and tend to self‐assemble into ...

Advanced Functional Materials, EarlyView.Engineering MnNiPx cathodes through the dual role of Mn simultaneously improves hydrogen evolution reaction activity and intermittent‐operation durability. Mn preferentially oxidizes to protect Ni–P sites from irreversible oxidation, while metallic Mn incorporation enhances the HER kinetics of Ni–P active layer.
