A comparison of established and digital surface model (DSM)‐based methods to determine population estimates and densities for king penguin colonies, using fixed‐wing drone and satellite imagery

Remote Sensing in Ecology and Conservation, EarlyView.
We used fixed‐wing drones and Beyond Visual Line of Sight flying to create high‐resolution imagery and Digital Surface Models (DSMs) of six large king penguin colonies (colony population sizes ranging from 10,671 to 132,577 pairs) in South Georgia. We used a novel DSM‐based method to facilitate automated and semi‐automated counts of each colony to ...

Impacts of fire on canopy structure and its resilience depend on successional stage in Amazonian secondary forests

Remote Sensing in Ecology and Conservation, EarlyView.
We analyzed the effects of fire on secondary forests' vertical structure in different successional stages using lidar metrics. Our results show that independently of the successional stage, secondary forests that experienced fire were more degraded than unburned secondary forest areas. Overall, our results show that forests in early successional stage (

Leveraging Blockchain and Smart Contracts to Combat Greenwashing in Sustainable Development

Sustainable Development, EarlyView.
ABSTRACT Blockchain technology, when combined with smart contracts, enables buyers to distinguish between greenwashed and genuinely eco‐friendly products. The presence of counterfeit items can severely impact supply chains by diminishing brand value, eroding consumer confidence, and undermining market trust.

Making Synthetic 2D Graphene Oxide Nanosheets by Electrochemical Oxidation of Commercial Carbon Fibres

Small, EarlyView.
A scalable, sustainable method is presented for synthesising high‐quality graphene oxide (GO) nanosheets from carbonized polyacrylonitrile (PAN) fibres via electrochemical exfoliation in nitric acid. This method produces monolayer GO with consistent thickness (≈0.9 nm) and unique circular and oblong morphology, reducing dependence on natural graphite ...

Controlled Nanoconfinement in a Microfluidic Modular Bead Array Device via Elastomeric Diaphragm Collapse for Enhancing Biomolecular Binding Kinetics

Small, EarlyView.
A modular platform for controlled nanoconfinement over a large area is presented using an elastomeric diaphragm integrated with strain sensors and microfabricated posts (≈500 nm) to enhance biomolecular binding by alternating between confinement and bulk transport for rapid DNA immobilization and screening aptamers on their binding affinities to target
