Char Layer Thickness Evolution During Structural Timber Fire Experiment and Final Density Profile
Fire and Materials, EarlyView.ABSTRACT This paper evaluates several non‐destructive experimental methods for determining the char layer thickness and its density profile in structural timber samples exposed to standard ISO 834 fire curve experiments. Microwave echo pulse, ultrasonic echo pulse, X‐ray computed tomography, and resistance drilling were evaluated.

Styrene and its natural analogues: accumulation and sustainable production methods
Journal of the Science of Food and Agriculture, EarlyView.Abstract Styrene, also known as vinyl benzene, is a colourless, highly volatile petrochemical that serves as a key monomer in the production of polystyrene and styrene‐butadiene rubber. Its industrial synthesis via the alkylation of benzene with ethylene relies on fossil fuels, requiring high temperatures and toxic catalysts that contribute to ...

Low‐Hysteresis Cellulose‐Based Hydrogels for Strain Detecting
Macromolecular Rapid Communications, EarlyView.Low‐hysteresis hydrogel with high cellulose content is prepared. The modified cellulose is prepared through a sequential periodate oxidation and borohydride reduction process. The hydrogel can be used as a strain sensor with a gauge factor of 1.1 in the 0%–300% sensing range.

People 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.

Roll‐to‐Roll Processing of Biodegradable Multilayer Barrier Packaging Structures
Packaging Technology and Science, EarlyView.This work demonstrates that novel packaging materials built using biobased and biodegradable materials can be produced in pilot‐scale and converted into functional barrier packaging. The proposed structures are anticipated to make a strong impact in use‐cases where the risk of environmental littering is elevated, such as snacks and take away meals ...
