TL;DR: In this article, the effect of high gravity level (G) on the particle size and its distribution of α-Fe2O3 was explored and it was found that increasing the G of a rotating packed bed (RPB) is beneficial for the formation of particles with smaller particle sizes and narrower size distribution.

TL;DR: In this paper, the deflagration behavior of pure and doped ammonium perchlorate (AP) was studied over the pressure range 300-6000 psia, using cinephotomicrography of burning samples and scanning electron microscopy of quenched samples.
Abstract: The deflagration behavior of pure and doped ammonium perchlorate (AP) was studied over the pressure range 300–6000 psia, using cinephotomicrography of burning samples and scanning electron microscopy of quenched samples. Materials studied were pure AP in single-crystal and pressed-pellet forms, and single crystals with controlled isomorphous substitution of K + , MnO 4 − , and Cr 2 O 7 2− ions. This study shows that previous speculations regarding the combustion of AP are based on erroneous assumptions, and more realistic views, based on the observations, are proposed. In addition, some serious questions regarding the relevance of low-temperature, low heating rate, and low-pressure decomposition data to actual combustion are posed.

TL;DR: Experimental results indicated that 1 possesses potential application prospects in the field of explosives and propellants.
Abstract: A new solvent-free energetic MOF, [Pb(HBTI)]n (1) (H3BTI = 4,5-bis(1H-tetrazole)-1H-imidazole), has been synthesized under hydrothermal and acidic conditions. It were characterized by elemental analysis, IR, TG, DSC and SEM. Single crystal X-ray diffraction analysis revealed that 1 features a rigid 3D framwork architecture without solvent molecules. Thermoanalysis demonstrated that the thermostability of 1 was up to 325 oC. Non-isothermal kinetic and apparent thermodynamic parameters of exothermic decomposition process of 1 were determined by Kissinger's and Ozawa's methods. Through oxygen-bomb combustion calorimetry, the standard molar enthalpy of formation of 1 was determined. The calculated detonation properties (heat of detonation, detonation velocity and detonation pressure) and sensitivity tests of 1 were carried out. In addition, 1 was explored as combustion promoter to accelerate the thermal decompositions of ammonium perchlorate (AP) by differential scanning calorimetry. Experimental results indicated that 1 possess potential application prospect in the field of explosive and propellant.
