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.

Traffic Flow Data Collection Methods During Wildfire Evacuation

Fire and Materials, EarlyView.
ABSTRACT With climate change and urbanisation increasing wildfire risk in the wildland–urban interface (WUI), enhancing community evacuation preparedness is crucial. This study evaluates different data collection methods for measuring traffic flows during a community wildfire evacuation drill in Roxborough Park, Colorado, in June 2024.

Multi‐synergistic strategy for dual‐sensing conductive hydrogels capable of simultaneous strain and temperature monitoring

FlexMat, EarlyView.
In this study, a multicomponent synergistic strategy is utilized, which capitalizes on the “intersection” of multiple functional influencing factors to achieve the successful development of a multifunctional hydrogel. Through the construction of a unique three‐dimensional dynamic cross‐linked network, the material combines mechanical strength ...
