Covalently Immobilized Lignin–Xanthene Conjugates for Persistent Surface Photochemistry and Self‐Sterilizing Interfaces Under Ambient Visible Light

open access: yesMacromolecular Rapid Communications, EarlyView.
Bio‐derived lignin–Eosin Y macromolecular networks are developed as visible‐light‐responsive self‐sterilizing coatings that generate reactive oxygen species without leaching. The spray‐coated photopolymerized surfaces exhibit durable antibacterial and antiviral activity under ambient light for extended periods, demonstrating a scalable and sustainable ...

The Relationship between Different Proofs of Load-Bearing Capacity, Fire Resistance of the Cross-Section and the Price of Solid Softwood

open access: yesBuildings
The impact of ultimate limit state checks on the fire resistance of the cross-section (element) of softwood structural timber is analyzed in this study, which was found to depend on the cross-sectional area, strength class or material quality expressed ...

Caring for forests between attitude and platitude. Social relationships with nature in industrial forestry in Äänekoski, Finland

open access: yesPeople and Nature, EarlyView.
Abstract Forests play a pivotal role in sustainability transitions. This article explores how people's relationships with forests, particularly how they care for or take care of them, shape and reflect broader tendencies and tensions in forest utilization and governance.

Performance of Glass Fiber Composites With Plastic‐Waste Pyrolysis Char as Filler

open access: yesPolymer Composites, EarlyView.
Valorisation of mixed plastic waste into carbonaceous char via pyrolysis, its integration as a microfiller in epoxy/E‐glass (GFRP) laminates, and characterisation to assess composite performance as a function of filler loading. ABSTRACT Plastic pyrolysis offers circular solutions for mixed plastic waste but leaves a carbonaceous char that is often ...

Reinforcement and Rheology of Epoxy‐Mediated Lignin Integration in Carboxylated Nitrile Rubber

open access: yesPolymer Engineering &Science, EarlyView.
The interaction of lignin‐epoxy resin‐XNBR and the effect of lignin on the nonlinear rheological behavior of epoxy‐cured XNBR/lignin composites. ABSTRACT Lignin has attracted increasing interest as a renewable filler for rubber composites; however, it shows weaker reinforcing efficiency than conventional fillers such as carbon black and silica ...

Flexural anisotropy of rift-sawn softwood boards induced by the end-grain orientation

open access: yesJournal of Wood Science, 2021
Inspired by the use of rift-sawn softwood board for covering curved surfaces in Kokerabuki, a traditional Japanese roofing method, we investigated the flexural anisotropy of wood caused by its end-grain orientation.

Almond Shell‐Derived Cellulosic Microfibres: Extraction, Characterisation and Applications in Sustainable Paper‐Based Packaging

open access: yesPackaging Technology and Science, EarlyView.
Cellulosic microfibres were extracted from almond shells using organosolv, soda and kraft processes, and comprehensive physicochemical, surface, thermal and morphological characterisation demonstrated their strong potential as sustainable fillers for paper‐based packaging application. ABSTRACT This study develops pathways for the valorisation of almond
