Quantification of Magnetic Interactions in van der Waals Heterostructures Using Lorentz Transmission Electron Microscopy and Off‐Axis Electron Holography

open access: yesAdvanced Materials, EarlyView.
Cross‐sectional Lorentz TEM and off‐axis electron holography visualize the magnetic domain structure and quantify interlayer coupling in Fe3GeTe2/graphite/Fe3GeTe2 heterostructures. A stray‐field coupling length of 37±$\pm$7 nm marks the onset of domain misalignment between the layers.

The Radon and Hilbert transforms and their applications to atmospheric waves

open access: yesAtmospheric Science Letters
The Radon and Hilbert transform and their applications to convectively coupled waves (CCWs) are reviewed. The Hilbert Transform is used to compute the wave envelope, whereas the Radon transform is used to estimate the phase and group velocities of CCWs ...

Near‐Infrared Imaging of H2O2 in Plants With Nanosensors Under Environmentally Changing Conditions

open access: yesAdvanced Materials, EarlyView.
This paper reports a ratiometric nanosensor enabling robust, multivariate detection of stress signals (H2O2) in plants, with high resistance to light fluctuations and mechanical disturbances. Single‐walled carbon nanotubes serve as the sensor, Egyptian Blue nanosheets serve as a stable reference, and plant autofluorescence serves as a label‐free ...

Rocket-induced lower ionosphere disturbances derived from measurements of very low frequency transmitter signals

open access: yesEarth and Planetary Physics
A rocket launch can induce large-scale atmospheric disturbances, which have mainly been investigated in previous studies by using measurements of total electron content.

Orthogonal Passivation of Polar Facets for Efficient InSb Quantum Dot SWIR Photodetectors

open access: yesAdvanced Materials, EarlyView.
An orthogonal passivation strategy is developed for indium antimonide (InSb) colloidal quantum dots (CQDs): a metal halide passivates Sb‐terminated surface sites, while thiol ligands passivate In‐terminated sites. This site‐specific passivation reduces trap density, prolonging carrier lifetime and increasing carrier mobility, and enables InSb CQD ...

Life‐Like Ferrous Oxide Microspheres from Kombucha

open access: yesAdvanced Materials Interfaces, EarlyView.
Kombucha bacterial cellulose, sodium alginate, and ferrous nitrate self‐assemble into membrane‐enclosed iron oxide microspheres. These microspheres bud daughter vesicles, sustain 24‐h electrochemical oscillations, and filter theta‐band signals.

Oxygen‐Controlled Structural and Defect Engineering of Magnetron‐Sputtered ZnO Thin Films for Photosensing

open access: yesAdvanced Materials Interfaces, EarlyView.
Zinc oxide thin films are engineered by controlling oxygen flow and nominal partial pressure during growth to tune atomic‐scale defects and crystallographic texture that limit device performance. By balancing competing defects, the films achieve improved preferential c‐axis orientation and enhanced ultraviolet photoresponse.

Neuromorphic Training of VO2 Device at Behavioral Timescale Inspired by the Plasticity of CA1 Neurons of Live Mouse Brain

open access: yesAdvanced Materials Interfaces, EarlyView.
A VO2 device can act as a functional analog for behavioral timescale synaptic plasticity noted in the mouse brain by current pulsing. ABSTRACT Realizing biologically relevant plasticity rules in hardware is a central goal in neuromorphic computing.
