Long-term radiance evolution of a tritium-powered radioluminescent device based on a cellulose aerogel loaded with Y2O3:Eu3+ microphosphors

This paper reports the first systematic 16-month monitoring of a tritium-powered radioluminescent device based on Y2O3:Eu3+-loaded cellulose aerogel, revealing an atypical non-monotonic radiance evolution that suggests complex sequential mechanisms within the material and highlights its potential for long-term implantable photobiomodulation applications.

Micro/Nanoplastic Formation by Polymer Processing

This study reveals that melt extrusion, a standard polymer processing step, is an intrinsic source of micro- and nanoplastics across diverse polymer chemistries due to phase separation caused by oxidized chain scission, necessitating new mitigation strategies to prevent chain degradation at the source.

Influence of Spider Silk Reinforcement on the Thermal Stability and Degradation Kinetics of PLA/Starch Biocomposites

This study demonstrates that while starch reduces the thermal stability of polylactic acid (PLA), the addition of spider silk reinforcement effectively mitigates this destabilizing effect and enhances thermal resistance and char formation, making it a promising bio-reinforcement for sustainable PLA-based packaging.
