Tiinamari Seppänen, Kristoffer Meinander, Monika Österberg, Emily D. Cranston, Tekla Tammelin   Advanced Materials Intefaces 2025, XX, XX, XXXX-XXXX Abstract : Porous cellulose and nanocellulose materials, such as foams and aerogels, are widely used in numerous applications due to their large surface area, sorption capacity, mechanical resilience, and overall versatility. Additionally, porous cellulose materials provide extensive interaction sites that can facilitate a variet

Yuya Fukata, Aayush Kumar Jaiswal, Ari Hokkanen, Hannes Orelma, Tadahisa Iwata   Advanced Functional Materials 2025, XX, XX, XXXX-XXXX Abstract : Polymer optical fibers (POFs) are widely used in short-distance communication and sensing, but current fibers rely on petroleum-based polymers such as polymethyl methacrylate (PMMA), which soften near 100 °C and lack renewability. Cellulose-derived fibers have been proposed as sustainable alternatives, yet progress is hindered by so
