Ground‐truthing of satellite imagery to assess seabird colony size: A test using Adélie penguins

open access: yesRemote Sensing in Ecology and Conservation, EarlyView.
Adélie penguin colony size can be estimated from space using very high‐resolution (VHR; 0.3–0.6 m resolution) satellite imagery due to the contrast between their guano stain and the surrounding terrain. Our study assessed the utility of VHR imagery for making indirect assessments of changes in colony size.

X‐ray and γ‐ray Sensing from Aqueous‐Based Lead Sulfide Telluride Nanocomposites

open access: yesSmall, EarlyView.
PbSxTey nanoparticles integrate into flexible, size‐scalable aramid polymeric scaffolds, forming percolation paths capable of efficiently transporting the electrons and holes created by penetrating photonic interactions. The resulting nanosemiconductor‐nanofiber composite forms the basis for room‐temperature spectroscopic sensors of X‐rays and γ‐rays ...

Experimental Analysis of the Nb(C,N) Pinning Effects on Austenite Grain Growth Coupled with Mean‐Field Simulations

open access: yessteel research international, EarlyView.
Refining austenite is key to preventing surface cracks during continuous casting of. This study combines in situ high‐temperature confocal microscopy with mean‐field simulations to model grain size evolution, highlighting the grain‐refining effect of niobium carbonitride precipitates on the austenitic microstructure.
