DuckNet: an open‐source deep learning tool for waterfowl species identification in UAV imagery

Remote Sensing in Ecology and Conservation, EarlyView.
Using drones with thermal‐RGB sensors and a deep learning model (RetinaNet with ResNet‐50), we surveyed non‐breeding waterfowl across restored wetlands in the Mississippi Alluvial Valley. Our model, DuckNet, achieved high accuracy and offers an open‐source, customizable tool for automated waterfowl detection to support conservation monitoring ...

Electrospun PAN Membrane Loaded with AgInP2Se6 Nanosheets for Triboelectric Energy Harvesting

Small, EarlyView.
Exfoliated AgInP2Se6 nanosheets are incorporated into a polyacrylonitrile (PAN) polymer matrix by electrospinning and applied for the first time in a triboelectric nanogenerator (TENG). The hybrid membrane delivers strong electrical output and exhibits reversible humidity sensitivity, responding rapidly to changes in relative humidity.
