Combustion Properties of Timber in Historic Structures: Case Study of the São Pedro de Alcântara Chapel Fire

Fire and Materials, EarlyView.
ABSTRACT Timber plays a fundamental role in the fire performance of historic building components, where ageing and environmental exposure can markedly influence its physical and chemical properties. This study presents an experimental investigation of the fire behaviour of Ocotea sp.

Study of Damage to Shutters Exposed to a Vegetation Fire: Definition of Vulnerability Thresholds

Fire and Materials, EarlyView.
ABSTRACT This study examines the fire behavior of wooden, PVC, and aluminum shutters through laboratory and large‐scale experiments. Laboratory tests were conducted using a cone calorimeter to assess the ignitability of the PVC and wooden shutters, focusing on the critical heat flux of ignition, ignition time and critical Flux Time Product (FTP ...

Experimental Characterization of the Effects of Mineral‐Based Fire‐Retardant Admixtures on the Combustion Properties of Polyethylene Blends

Fire and Materials, EarlyView.
ABSTRACT The growing demand for flame retardant (FR) polymeric materials has highlighted the need to improve the combustion behaviour of highly flammable polymers such as polyethylene (PE). This study investigates the use of eco‐sustainable mineral FRs as a strategy to reduce heat release and smoke production during combustion, while improving the ...

The research progress in polyethylene oxide polymer electrolytes

FlexMat, EarlyView.
Polyethylene oxide (PEO) has become the mainstream matrix material for solid polymer electrolytes (SPEs) due to its excellent lithium salt complexation ability and processability. However, its high crystallinity results in low ionic conductivity at room temperature and difficulty in suppressing lithium dendrite growth, which significantly hinders the ...

Ignition of a rectangular solid by an external heat flux [PDF]

, 1994
The influence of corners on the ignition of a solid exposed to a surface energy flux is analyzed with large activation energy asymptotics. We begin with the analysis of the ignition of semi-infinite wedges by a constant heat flux.

The Energy Dilemma: Does Energy Security Risk and Renewable Energy Affect Fossil Material Footprint? Policy Framework for Securing SDGs

Geological Journal, EarlyView.
Energy security risk has a positive impact on material footprint. Renewable energy consumption reduces material footprint. ABSTRACT Following a high economic growth path, the group of G7 economies is found to be utilising more and more material, causing a material footprint (MF), which in turn contributes to pollution.

Progress in the Role of Mast Cells and Biomolecular Signals in the Mechanism of Postoperative Ileus: From Cellular Activation to Exploration of the Brain–Gut Axis

Gut Medicine, EarlyView.
ABSTRACT Postoperative ileus (POI) is a frequent complication after surgical procedures, predominantly manifesting as aberrant gastrointestinal motility, which markedly extends the duration of postoperative recovery for patients. The clinical duration of POI is typically modulated by intricate inflammatory cascades, with mast cells assuming a critical ...
