Long‐term monitoring reveals biomass loss and concurrent dominance changes in coastal zooplankton community

open access: yesEcography, EarlyView.
Anthropogenically induced changes in environmental conditions have been affecting species communities globally, leading to shifts in ecosystem functioning. Physical drivers like temperature, salinity and acidification are especially important in coastal ecosystems, and high‐resolution time‐series are essential to identify how these variables affect ...

Strong interfacial charge transfer from CrSBr induces extreme hole doping and quantum‐Hall states in graphene heterostructures

open access: yesInfoScience, EarlyView.
Magnetic van der Waals semiconductors offer unique opportunities to integrate spin and charge degrees of freedom in atomically thin devices. We fabricate dual‐gated heterostructures consisting of exfoliated CrSBr and monolayer graphene with Hall measurement revealing robust heavy p‐doping of graphene and signals of h‐BN/graphene moiré superlattices ...

Large Igneous Province Record Through Time and Implications for Secular Environmental Changes and Geological Time‐Scale Boundaries

open access: yesGeophysical Monograph Series, Page 1-26., 2021

Exploring the links between Large Igneous Provinces and dramatic environmental impact

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

Weyl points and anomalous transport effects tuned by the Fe doping in Mn3Ge Weyl semimetal

open access: yesNew Journal of Physics
The discovery of a significantly large anomalous Hall effect in the chiral antiferromagnetic system—Mn _3 Ge—indicates that the Weyl points are widely separated in phase space and positioned near the Fermi surface.

Most costly and prevalent reasons for hospitalization in children with medical complexity in Ontario, Canada

open access: yesJournal of Hospital Medicine, EarlyView.
Abstract Background and Objectives Children with medical complexity (CMC) have chronic health conditions often associated with functional limitations. CMC comprise 1%–5% of the pediatric population. In Canada, their care accounts for one‐third of pediatric health spending.

Effect of Fe Doping on the Structural, Morphological, Optical, and Magnetic Properties of Ca2InTaO6 Double Perovskite

open access: yesphysica status solidi (b), EarlyView.
Fe‐doped Ca2InTaO6 double perovskites are synthesized via solid‐state reaction and systematically investigated. Rietveld refinement confirms orthorhombic Pbnm structure, while optical studies reveal a bandgap narrowing from 3.31 to 2.84 eV. Photoluminescence spectra exhibit strong red emission at 671 nm with optimal intensity at 10 mol% Fe ...
