Development of Flame Retarded Battery Casings Using Glass Fiber‐Reinforced Epoxy Resin

Polymer Composites, EarlyView.
Development of flame retarded battery casings using glass fiber‐reinforced epoxy resin by exploiting the synergistic action of APP and TiO2 to promote the formation of a coherent ceramic‐phosphate char layer. ABSTRACT This study investigates the development of glass fiber‐reinforced epoxy resin composites with enhanced fire performance for application ...

Emission of ions and charged soot particles by aircraft engines [PDF]

Atmospheric Chemistry and Physics, 2003
In this article, a model which examines the formation and evolution of chemiions in an aircraft engine is proposed. This model which includes chemiionisation, electron thermo-emission, electron attachment to soot particles and to neutral molecules ...

Performance improvement of carbon fiber‐reinforced ABS composites by introducing fullerene nanoparticles

Polymer International, EarlyView.
Fullerene particles were incorporated with CF‐reinforced acrylonitrile–butadiene–styrene terpolymer (ABS) matrix at three different compositions by a melt‐compounding process. These insights are crucial for the optimization of conductive hybrid composites for various applications.

Exploring Soot Particle Concentration and Emissivity by Transient Thermocouples Measurements in Laminar Partially Premixed Coflow Flames

Energies, 2017
Soot formation in combustion represents a complex phenomenon that strongly depends on several factors such as pressure, temperature, fuel chemical composition, and the extent of premixing. The effect of partial premixing on soot formation is of relevance

Negative Chemotaxis of Urease‐Functionalized Polymeric Microcapsules

Small, EarlyView.
Urease‐functionalized PLGA microcapsules exhibit negative chemotaxis in urea gradients, migrating from high to low substrate concentrations. Increasing gradients enhance chemotaxis until a plateau, while increasing average substrate concentration in a fixed gradient reverses chemotactic behavior.

Influence of the collecting substrate's nature on structure and properties of Gajal soot

Bibechana
Gajal soot, a black carbonaceous residue, was prepared by burning sesame oil with the aid of threaded cotton in a copper oil lamp. Substrates made of clay, iron, and bronze were separately used for the collection of the Gajal soot, herein named as GS-CS,

Fire Testing and Hazard Assessment for Flame Retardant Polymer Composites

Safety Science and Technology, EarlyView.
Flame retardant polymer composites are now being evaluated with more than pass or fail flammability tests. Heat release, smoke, toxicity, and system‐level behavior are receiving more attention, and multi‐scale methods are being used to describe fire hazard under more realistic conditions.

Atmospheric tar balls: Particles from biomass and biofuel burning [PDF]

, 2004
"Tar balls'' are amorphous, carbonaceous spherules that occur in the tropospheric aerosol as a result of biomass and biofuel burning. They form a distinct group of particles with diameters typically between 30 and 500 nm and readily identifiable with ...

Processing of soot in an urban environment: case study from the Mexico City Metropolitan Area [PDF]

Atmospheric Chemistry and Physics, 2005
Chemical composition, size, and mixing state of atmospheric particles are critical in determining their effects on the environment. There is growing evidence that soot aerosols play a particularly important role in both climate and human health, but ...

Soot aerosols from commercial aviation engines are poor ice-nucleating particles at cirrus cloud temperatures [PDF]

Atmospheric Chemistry and Physics
Ice-nucleating particles catalyze ice formation in clouds, affecting climate through radiative forcing from aerosol–cloud interactions. Aviation directly emits particles into the upper troposphere where ice formation conditions are favorable.
