Heterointerface‐Engineered SiC@SiO2@C Nanofibers for Simultaneous Microwave Absorption and Corrosion Resistance

open access: yesAdvanced Science, EarlyView.
The novel heterointerface engineering strategy integrates a SiO2 interlayer and amorphous carbon shell onto SiC nanofibers, enhancing microwave absorption and corrosion resistance. Abstract To meet the demands of maritime defense and transportation, next‐generation microwave absorption (MA) materials must combine efficient attenuation and corrosion ...

Topological Skyrmion‐Based Spin‐Torque‐Diode Effect in Magnetic Tunnel Junctions

open access: yesAdvanced Electronic Materials, EarlyView.
Electrical excitation and detection of a breathing skyrmion in a nanoscale skyrmion‐based spin‐torque diode at room temperature is achieved. Skyrmions are generated via spin‐transfer torque current induction, and their breathing dynamics are observed through ferromagnetic resonance (FMR) measurements.

Relationships among tissues, biofluids, and otolith selenium concentrations in wild female burbot (Lota lota)

open access: yesIntegrated Environmental Assessment and Management, EarlyView., 2023
Abstract In the Lake Koocanusa‐Kootenai River system (Montana, USA and British Columbia, Canada), selenium (Se) contamination has become an international concern and is suspected to contribute to the observed burbot (Lota lota) population collapse. Due to our limited ability to sample burbot in Lake Koocanusa for monitoring studies, we used a reference
