TL;DR: It is demonstrated that detention times of packed-bed bioreactors can be substantially reduced using isolate KJ, but that larger concentrations of acetate will be necessary to reduce perchlorate to low levels necessary for drinking water.

TL;DR: MgO nanoparticles with an average size of 30nm were prepared by a traditional solgel method using magnesium chloride and NaOH aqueous solution as the raw materials X-ray diffraction (XRD) and transmission electron microscopy (TEM) were used to characterize the products as mentioned in this paper.

TL;DR: In this paper, a number of experimental techniques were developed for describing the characteristics of the CCPs as a function of the oxidizer particle size and pressure. But the results of these experiments were limited to the case of aluminized solid propellants.
Abstract: Experimental results are presented on the formation of condensed combustion products (CCPs) at the burning surface of aluminized solid propellants. A number of experimental techniques were developed for describing the characteristics of the CCPs as a function of the oxidizer particle size and pressure. The results of this investigation provide qualitative descriptions of the CCPs formed at the propellant burning surface as functions of oxidizer particle size and pressure.
