An Independent Post-Publication Bioindicator Study Supplementing the Environmental-Safety Discussion of Fiber-Based Perovskite Solar Cells

This independent post-publication study demonstrates that polyolefin elastomer (POE) encapsulation significantly suppresses lead migration from fiber-based perovskite solar cells into a soil-plant system over 90 days, reducing bioindicator uptake to approximately one-tenth of unencapsulated controls through mechanisms like restricted diffusion and reduced water ingress.

Cellulose microfibril interactions with water: A density functional theory study of H2O incorporation into the cellulose microfibril structure

This study utilizes periodic density functional theory calculations to demonstrate that water molecules can incorporate into the interior of cellulose microfibrils to strengthen the structure via hydrogen bonding without disrupting the crystalline arrangement, while also evaluating external hydration pathways for potential hydrolysis and deuterium exchange.

Resolving Ontological Circularity and Pedagogical Confusion Inherent in the 2019 Mole Definition by Recognizing the Elementary Amount and Adopting the Entity as the Appropriate Atomic-Scale Amount Unit

This paper proposes resolving the ontological circularity and pedagogical confusion of the 2019 mole definition by introducing the "elementary amount" (nan_a) as a fundamental constant and the "entity" (ent) as an atomic-scale unit, thereby establishing amount of substance as a distinct physical dimension independent of the mole.

Waste valorization of coconut shell char as a partial cement replacement in sustainable mortar: fresh-state, setting, and mechanical performance

This study demonstrates that incorporating 5–10% coconut shell char, produced via pyrolysis, as a partial cement replacement optimizes the balance between fresh-state properties and mechanical performance in sustainable mortar, with the 5% dosage yielding superior compressive and flexural strengths compared to the control.

Comparative analysis of phthalate leachate in U.S., Oceania, and European recycled consumer PET bottles: assessing the impact of regulatory policies and recycled content.

This study utilizes GC-MS analysis to demonstrate that European PET bottles, which are subject to stricter additive regulations and mandatory recycled content, exhibit significantly lower phthalate leaching concentrations compared to those from the U.S. and Oceania, highlighting the effectiveness of regulatory policies in reducing chemical exposure.
