Development and Characterization of Mikania, Kapok, Wool, Sugarcane, and Pineapple Fiber Reinforced Polyester Composite

open access: yesEngineering Reports, Volume 7, Issue 1, January 2025.
Incorporating plant‐derived fibers like Mikania, wool, kapok, sugarcane, and pineapple into polyester composites significantly enhances mechanical properties, as shown through tensile, impact, and SEM analysis. Pineapple‐based composites exhibited the highest tensile strength (42.4822 N/mm2) and maximum stretch (4.27950%), while kapok contributed to ...

Pollinators respond positively to urban green space enhancements using wild and ornamental flowers

open access: yesInsect Conservation and Diversity, Volume 18, Issue 1, Page 16-28, January 2025.
Green spaces enhanced for nature are higher in pollinator diversity and are more resilient to urbanisation than unenhanced green spaces. Additional non‐native floral plantings at enhanced sites attract a higher diversity of pollinators and more Dipteran visits than sites only enhanced with native wildflowers, supporting a mixed‐planting approach ...
