Melt Electrospinning of Poly (ε‐Caprolactone)/Polyethylene Oxide/Polyethylene Glycol—Hydroxyapatite Nanocomposite Fibers: Morphology, Properties, and Hydrolytic Degradation

open access: yesPolymer Engineering &Science, EarlyView.
The fabrication of nanocomposite fibers based on a ternary PCL/PEO/PEG blend reinforced with hydroxyapatite nanoparticles via melt electrospinning resulted in improved nanoparticle uniformity, fine‐tuning of the microstructure and mechanical properties, and accelerated hydrolytic degradation; features that make this system a promising platform for bone

Permafrost Distribution in the Canadian Rockies: Key Variables Influencing Patch‐Scale Variability

open access: yesPermafrost and Periglacial Processes, EarlyView.
ABSTRACT The spatial distribution of permafrost in mountainous regions is influenced by various factors such as topography, climate, vegetation, and substrate. Despite the existence of comprehensive permafrost maps at national and global levels, they fail to accurately represent the patch‐scale (e.g., < 25 m) permafrost distribution in characteristic ...

Control System for the Navigation of the Agricultural Robots: A Review

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Control systems for the navigation of autonomous agricultural robots—particularly those operating in uneven terrain and in the presence of static or dynamic obstacles—have advanced considerably in recent years. As conventional machinery evolves toward increasingly automated systems, the design of reliable navigation controllers has become ...

Investigating the Environmental Impact of Additive Construction: A Systematic Analysis of the Life Cycle Assessment Studies

open access: yesSustainable Development, EarlyView.
ABSTRACT Additive Manufacturing (AM) has been identified as a potential catalyst for a paradigm shift within the construction industry, due to its capacity to enhance sustainability, reduce waste, and augment design flexibility. This study presents a systematic literature review (SLR) that explores the application of Life Cycle Assessment (LCA) in ...

Symbols of Climate Action: Audit Labor and the Production of Carbon Credits

open access: yesEconomic Anthropology, EarlyView.
ABSTRACT Voluntary carbon markets (VCMs) are promoted as tools for financing climate mitigation, yet their effectiveness and credibility remain contested. This article examines how carbon credits are produced and destabilized as symbols of climate action, emphasizing the forms of ecological and audit labor that sustain their legitimacy.
