Investigation of Crystal Structure Change and Mechanical Properties of 3D Printed PLA After Annealing

open access: yesPolymer Engineering &Science, EarlyView.
Thermal annealing of FDM‐printed PLA significantly enhances longitudinal tensile and flexural strengths by increasing crystallinity to 46.6%. However, transverse properties remain constrained by weak interlayer adhesion, providing crucial insights into the anisotropic thermo‐mechanical behavior of printed biopolymers for demanding engineering ...

Compatibilization and Reinforcement of PHB/PBAT Blends via Sequential Blending of Surface‐Modified Cellulose

open access: yesPolymer Engineering &Science, EarlyView.
Sequential blending improved the mechancial properties of PHB/PBAT/cellulose composites as compared to the one‐step batch mixing method. ABSTRACT Polyhydroxybutyrate (PHB) is a natural and biodegradable polymer generated by bacteria. While its applications to potentially replace petroleum‐based plastics are severely limited due to its brittleness and ...

The Ethical Dimensions of Climate Change: Rethinking Justice, Responsibility, and Collective Obligation

open access: yesSustainable Development, EarlyView.
ABSTRACT Climate change is one of the most profound ethical and existential challenges of the 21st century. Beyond its physical, economic, and environmental consequences, it raises fundamental moral questions about justice, equity, responsibility, and the right to a livable planet.
