TL;DR: Porous fly ash-based geopolymer material was produced using fly ash and sodium water glass as original material and H 2 O 2 as foaming agent in this paper, where the changes caused by the geopolymersization and decomposition of H 2O 2 on the properties of the final products were investigated by applying curing on geopolym mortars with different amounts of sodium waterglass (60, 80 and 100 ǫ) and H2 O 2 (4, 6 and 8 g) added at various curing temperatures.

TL;DR: In this article, Li ion batteries at different states of charge were tested using a cone calorimeter to study the burning behaviors under an incident heat flux of 50kW/m−2.

TL;DR: In this article, aramid fibers reinforced silica aerogel composites (AF/aerogels) for thermal insulation were prepared successfully under ambient pressure drying, and the microstructure showed that the aramid fibers were inlaid in the Aerogel matrix, acting as the supporting skeletons, to strengthen the aerogels matrix.

TL;DR: In this article, a novel effective medium theory was proposed to model the thermal conductivity of porous materials, where phases (or components) are treated as small spheres dispersing into an assumed uniform medium with thermal conductivities km.

TL;DR: Data in these stages concerning pre-movement time, walking speed, occupant characteristics, actions and exit choice decisions are compiled and can be used as input parameters for evacuation models in PBD or in validating the evacuation models’ accuracy.
