Biobased Polyurethane Films Based on Andiroba (Carapa guianensis) and Buriti (Mauritia flexuosa) Oil Polyols

open access: yesJournal of Applied Polymer Science, EarlyView.
Polyurethane films were prepared from andiroba (Carapa guianensis) and buriti (Mauritia flexuosa) oil‐derived polyols, emphasizing their potential as bio‐based materials. UV–Vis analysis indicates the retention of carotenoid‐related chromophoric features within the polymer matrix.

Additives Enhancing Biodegradability in Plastics and Potential Implications for Textiles: A Mechanistic Review

open access: yesJournal of Applied Polymer Science, EarlyView.
Mechanistic insights from additive‐assisted plastic degradation guide the design of environmentally adaptive textile fibers. Functional additives enhance oxidative, hydrolytic, enzymatic, and microbial degradation pathways. Translating these strategies requires control of fiber architecture, additive distribution, and environmental interactions ...

Activity enhancement of carbon nanofiber-based catalysts for CO2 methanation by mechanochemical synthesis

open access: yes
Carbon nanofibers (CNFs) modified with CeO2 were employed as support for the synthesis of Ni catalysts for the CO2 methanation reaction. Two different preparation methods were investigated: incipient wetness impregnation and mechanochemical synthesis ...

Combined effect of increasing the post‐reformer temperature and adding red mud as a secondary catalyst in the thermocatalytic reforming of digestate

open access: yesBiofuels, Bioproducts and Biorefining, EarlyView.
Abstract This work studies the combined effect of increasing the post‐reformer temperature and introducing red mud as a support catalyst in the thermocatalytic reforming (TCR®) of digestate. The TCR® method, developed by the Fraunhofer Institute for Environmental, Safety and Energy Technology UMSICHT (abbreviated as Fraunhofer UMSICHT), is an extension
