Flame Temperatures Saturate with Increasing Dead Material in Ulex europaeus, but Flame Duration, Fuel Consumption and Overall Flammability Continue to Increase

Fire, 2019
A key determinant of wildfire behaviour is the flammability of constituent plants. One plant trait that influences flammability is the retention of dead biomass, as the low moisture content of dead material means less energy is required to achieve ...

Fire-retardant and fire-barrier poly(vinyl acetate) composites for sealant application

eXPRESS Polymer Letters, 2010
Fire-retardant ceramifying poly(vinyl acetate) (PVAc) sealants have been prepared. The degradation of PVA was integrated with the action of the fire retardants to reduce flammable gases, produce carbonaceous char and convert the fillers into a self ...

Flash points of mixtures of flammable and non‐flammable liquids [PDF]

Fire and Materials, 1976
AbstractA general theory is developed which enables closed‐cup flash‐points of mixtures of flammable and non‐flammable liquids to be predicted from a knowledge of certain properties of a flammability diagram. The theory illustrates, quantitatively, the effect of both the flame inhibiting properties of the vapour of the non‐flammable component and the ...

Discovering Early‐Stage Gas Generation Kinetics Enables Thermal Runaway Early Warning in Lithium‐Ion Batteries

Advanced Science, EarlyView.
Operando gas diagnostics reveal a previously unrecognized chemical activation (CA) stage during thermal runaway in lithium‐ion batteries. A physics‐informed gas generation kinetics network (GGKNet) is developed to reconstruct reaction pathways and physical models automatically.

Balancing Bulk Solution Chemistry and Cation Solvation for Stable Aqueous Aluminum Batteries

Advanced Science, EarlyView.
A dual‐scale electrolyte design balances bulk solution chemistry and cation solvation in aqueous aluminum batteries. Regulation of the bulk solution preserves high ionic conductivity and electrochemical stability, while modulation of the Al3+ solvation environment lowers desolvation penalties and suppresses hydrogen evolution. This balanced electrolyte
