Recently, inorganic low explosives, such as pyrotechnic composition, black powder, and ammonium nitrate, are commonly used in improvised explosive devices (IEDs) by the rioter or terrorists since these energetic materials can be obtained easily and legally from civilian markets....

A facile photosynthesis of trans-dioxoruthenium(VI) porphyrins.

Chemical communications (Cambridge, England)

Huang Y, Vanover E, Zhang R.

Photolysis of porphyrin-ruthenium(IV) dichlorate complexes with visible light results in homolytic cleavage of the O-Cl bond in the chlorates to form trans-dioxoruthenium(VI) species bearing either sterically encumbered or unencumbered porphyrin ligands.

Coulometrische titration von hypochloriten und chloraten.

Talanta

Gründler P, Holzapfel H.
PMID: 18960728
Talanta. 1970 Mar;17(3):246-8. doi: 10.1016/0039-9140(70)80076-5.

Hypochlorite was determined by direct coulometric titration with iron(II) in an acetate buffered solution. Chlorate was titrated with titanium(III) in 2M hydrochloric acid. Amperometric indication with one and two electrodes, respectively, was used. Mixtures of hypochlorites and chlorates, e.g.,...

In-source collision induced dissociation of inorganic explosives for mass spectrometric signature detection and chemical imaging.

Anal Chim Acta. 2015 Sep 10;892:1-9. doi: 10.1016/j.aca.2015.06.008. Epub 2015 Jul 08.

The trace detection, bulk quantification, and chemical imaging of inorganic explosives and components was demonstrated utilizing in-source collision induced dissociation (CID) coupled with laser desorption/ionization mass spectrometry (LDI-MS). The incorporation of in-source CID provided direct control over the extent...
