Integrating terrestrial and canopy laser scanning for comprehensive analysis of large old trees: Implications for single tree and biodiversity research

Remote Sensing in Ecology and Conservation, EarlyView.
Canopy laser scanning (CLS) enhances 3D measurements of large trees by lifting laser scanners into the canopy. Combining CLS with terrestrial laser scanning improves point cloud precision, reduces occlusion and enables detailed assessments of tree architecture and canopy biodiversity, opening new opportunities for forest ecology.

Flame Retardant Polyolefins Using Fibers From Leather Waste: Adjusting Extrusion Variables to Balance the Property Profile

Journal of Vinyl and Additive Technology, EarlyView.
Adjusting extrusion variables are a key to balance the flame retardancy and mechanical properties of polyolefin/leather waste fiber composites. ABSTRACT The extrusion processing variables represent a key to the optimal use of additives and thus the development of flame‐retardant polymer composites. Adjusting the property profile, for example, finding a
