TLDR
The NaHCO3/red-mud (RM) composite powders were successfully prepared by the solvent-anti-solvent method for methane explosion suppression and showed a much better suppression property than the pure RM or NaH CO3 powders.About:

Suppression of wood dust explosion by ultrafine magnesium hydroxide
Chuyuan Huang,Xianfeng Chen,Bihe Yuan,Hongming Zhang,Huaming Dai,Song He,Ying Zhang,Yi Niu,Shifei Shen +8 more
TL;DR: The experimental results show that explosion flame of wood dust is obviously suppressed by physical and chemical effects of Mg(OH)2 powders, and the suppression effect of nano-Mg( OH)2 is better than that of micron-MG(OH), under same mass fractions.

Inhibition of aluminum dust explosion by NaHCO3 with different particle size distributions.
TL;DR: Time-scale analysis indicated that the decomposition of NaHCO3 must be faster than the aluminum combustion reaction for effective chemical inhibition and an inhibition mechanism was proposed based on results.

Inhibition evaluation of ABC powder in aluminum dust explosion
TL;DR: The inhibition mechanism of aluminum dust explosion by ABC powder was summarized systematically based on results and the particles of the explosion residues of Al/NH3 mixture and Al/ABC mixture were significantly larger than those of pure aluminum explosion residues.

Effectiveness and mechanism of carbamide/fly ash cenosphere with bilayer spherical shell structure as explosion suppressant of coal dust
TL;DR: The suppression mechanism of carbamide/FAC composite suppressant was proposed, which was micro-nano multiscale complementary effect and deceleration-depressurization coupling effect and it showed that the surface-loaded carbamide particles had a particle size of ∼4 nm.

The roles of foam ceramics in suppression of gas explosion overpressure and quenching of flame propagation
TL;DR: The results demonstrate that the foam ceramics attenuate drastically the maximal explosion overpressure by up to fifty percent; the interconnected micro-network structure of the foam Ceramics contribute to quenching gas explosion flame and suppressing shock wave overpressure.

The effect of metal salts on premixed hydrocarbon—air flames
TL;DR: In this article, a study has been made of the inhibition of premixed flames by finely divided metal salts, some of which were found to be effective inhibitors of hydrocarbon combustion, and the mechanism of inhibition by powders probably involves this succession of steps: heating of the powder particles by the hot flame gases, evaporation of powder particles, decomposition or reaction of the evaporated material to provide metal atoms, and inhibition of the combustion process by the metal atoms.

Analytical aspects of chemically modified electrodes: classification, critical evaluation and recommendations
TL;DR: In this paper, the analytical aspects of chemically modified electrodes (CMEs) are critically reviewed and the effects of analyte and reagent accumulation, chemical transformation, electrocatalysis, permeability, ionic equilibria, controlled release, and change of mass, as well as combinations of these effects are evaluated and classified.
