Biodegradation of rocket propellant waste, ammonium perchlorate [PDF]
The short term effects of ammonium perchlorate on selected organisms were studied. A long term experiment was also designed to assess the changes incurred by ammonium perchlorate on the nitrogen and chloride contents of soil within a period of 3 years ...

Microscopic observations of X-ray and gamma-ray induced decomposition of ammonium perchlorate crystals [PDF]
, 1972 The X-ray and gamma-ray induced decomposition of ammonium perchlorate was studied by optical, transmission, and scanning electron microscopy. This material is a commonly used oxidizer in solid propellents which could be employed in deep-space probes, and

2,4-Dimethylanilinium perchlorate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2010 The crystal packing of the title compound, C(8)H(12)N(+)·ClO(4) (-), is stabilized by N-H⋯O hydrogen bonds, the protonated amine group acting as a hydrogen-bond donor with the perchlorate O atoms as acceptors. These connect neighbouring cations and anions, forming a two-dimensional network.

Evidence for Adsorption of Chlorine Species on Iron(III) (hydr)oxides in the Sheepbed Mudstone, Gale Crater, Mars [PDF]
Chlorine is a widespread element on Mars present in dust, soils and rocks, including the Sheepbed mudstone at Yellowknife Bay, Gale crater. Combined elemental and volatile analyses of two drilled samples, Cumberland and John Klein, indicated that ...

High performance ammonium nitrate propellant [PDF]
, 1979 A high performance propellant having greatly reduced hydrogen chloride emission is presented. It is comprised of: (1) a minor amount of hydrocarbon binder (10-15%), (2) at least 85% solids including ammonium nitrate as the primary oxidizer (about 40% to ...

4-Acetylpyridinium perchlorate [PDF]
Acta Crystallographica Section E Structure Reports Online, 2009 In the crystal of the title mol-ecular salt, C(7)H(8)NO(+)·ClO(4) (-), the ions are linked by N-H⋯O hydrogen bonds, resulting in chains propagating in [010]. The packing is reinforced by C-H⋯O inter-actions.
