Summary: The search for sustainable plastics is driven by the environmental pollution issues associated with petrochemical-derived plastics. Bioplastics, such as poly(lactic acid) (PLA), are increasingly being used in packaging due to limited fuel resources. However, poor ductility and gas barrier characteristics limit the use of PLA as food packaging material. This study aims to overcome these limitations by fabricating PLA/polyethylenimine-modified mesoporous silica (PEI-MS) composites. The influence of PEI content in MS and wt % loadings of optimized PEI content in MS on the properties of PLA is investigated in detail. The results show that PEI-MS modification improves the thermal stability and mechanical properties of PLA.

Summary: Carbon dots (CDs) are fluorescent nanoparticles with wide-ranging applications. However, their photostability and photoluminescence mechanism vary widely, and photobleaching can occur under intense light. This study investigates the photostability of different CDs and discovers that their resistance to photobleaching is correlated with their emission properties. The study also explores the influence of photobleaching dynamics on the photophysics of CDs.

Summary: The design of functional coatings for touchscreens and haptic interfaces is crucial in electronic devices. This study developed photoactivated anti-fingerprint coatings by incorporating 2D-SnSe2 nanoflakes into ordered mesoporous titania thin films. The resulting heterostructures showed enhanced ability to remove fingerprints and improved photocatalytic activity. The addition of SnSe2 did not affect the self-assembly process and the three-dimensional pore structure of the films. Furthermore, exposure of the films to sunlight and UV light completely eliminated fingerprints, suggesting potential applications in self-cleaning mechanisms.
