Anal Chem. 2015 Oct 06;87(19):9589-94. doi: 10.1021/acs.analchem.5b01775.

The explosive triacetone triperoxide (TATP) can be easily manufactured from readily accessible reagents and is extremely difficult to detect, owing to the lack of UV absorbance, fluorescence, or facile ionization. The developed method is based on the acidic hydrolysis...

Performance evaluation of a miniature ion mobility spectrometer drift cell for application in hand-held explosives detection ion mobility spectrometers.

Anal Bioanal Chem. 2009 Sep;395(2):411-9. doi: 10.1007/s00216-009-2818-5. Epub 2009 May 08.

The implementation of hand-held ion mobility spectrometers (IMS) requires the development and evaluation of miniature drift cells providing high sensitivity while maintaining reasonable resolution. This manuscript describes the construction of a miniature IMS designed for such an application and...

Application of LC-QTOF/MS for the validation and determination of organic explosive residues on Ionscan® swabs.

The identification and confirmation of trace explosive residues along with potential precursors and degradation products require a comprehensive laboratory analysis procedure. This study presents the determination of organic explosives consisting of hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX), 2,4,6-trinitrotoluene (TNT), 2,4,6,N-tetranitro-N-methylaniline (Tetryl), 1,3,5-trinitrobenzene (1,3,5-TNB)...

Shattering dissociation in high-energy molecular collisions between nitrate esters.

The Journal of chemical physics

Schweigert IV, Dunlap BI.
PMID: 21950861
J Chem Phys. 2011 Sep 21;135(11):114306. doi: 10.1063/1.3640000.

We present ab initio molecular dynamics simulations of head-on collisions between ethyl nitrate molecules at collisional energies from 200 to 1200 kJ/mol. Above a threshold energy, an increasing fraction of the collisions led to rapid dissociation on impact--"shattering." The...
