Jessica Borges-Vilches, Tuuli Virkkala, Valentina Guccini, Marko Crivaro, Thaddeus Maloney, Tekla Tammelin, Eero Kontturi   Reactive and Functional Polymers, 2026, 221, 106667 Abstract : Stimuli-responsive hydrogels are interesting, particularly in the realm of biomedicals, but often the fundamental response of their key physical properties is not simultaneously monitored. Here, we investigated the pH response on the porosity, rheological behavior, mechanical performance, and

Technol., 2026, 444, 133924 Abstract : This study presents a biobased dispersion coating formulated from natural wax and lignin nanoparticles providing hydrophobicity, stain resistance, and antimicrobial functionality for natural fiber textiles. Its durability is demonstrated and has potential for applic

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

Mattos   Advanced Functional Materials, 2025, XX, XXXX Abstract : A broadband blackbody requires both perfect anti-reflective characteristics and effective light entrapment spanning wavelengths from the mid-infrared (MIR) to the ultraviolet (UV) range. This ideal combination has not been achieved in several artificial superblack systems or even in naturall
