Thermal characterization of acetone peroxide mixtures with high energetic materials and raman based detection of concealed chemical threats
(2009)
This study was aimed at making contributions toward the understanding and detection of homemade explosives (HME). The properties and interactions between components in a blend of energetic materials with acetone peroxide, ...
Fourier transform infrared mapping to determine the distribution of active ingredients in pharmaceutical formulations
(2007)
A basic problem in pharmaceutical manufacturing is that a relatively simple formulation can produce widely varying therapeutic performance depending upon how the ingredients are distributed in the final matrix. Many methods ...
Standoff raman spectroscopy system for detection of explosives, chemical warfare agents simulants and toxic industrial compounds
(2008)
In this work a remote Raman system has been designed, assembled and tested for detecting explosives, Toxic Industrial Compounds (TIC) and Chemical Warfare Agents Simulants (CWAS) at laboratory scale up to 7 m target-telescope ...
Enhanced Raman Scattering of TNT on nanoparticles substrates: Ag, Au and Au/Ag Bimetallic colloids prepared by reduction with sodium citrate and hydroxylamine hydrochloride
(2007)
Surface-Enhanced Raman Scattering (SERS) provides extremely high sensitivity, due to increase in the Raman cross-sections of intrinsically very weak scattering events making these events comparable or even better than ...
Cyclic organic peroxides identification and trace analysis by Raman microscopy and open-air chemical ionization mass spectrometry
(2009)
The persistent use of cyclic organic peroxides in explosive devices has increased the interest in study these compounds. Development of methodologies for the detection of triacetone triperoxide (TATP) and hexamethylene ...
Experimental and Dft Studies of the mechanism of cetone-peroxide formation reaction using Raman and nuclear magnetic resonance spectroscopies
(2009)
A mechanism for the reaction between acetone and hydrogen peroxide leading to the formation of the important homemade explosive Acetone Peroxide is postulated. The proposed mechanistic scheme is based on Raman and Nuclear ...
Surface enhanced raman scattering of TNT on TiO2 substrates-photodegradation kinetics of explosives
(2007)
The majority of explosives found in antipersonnel and antitank landmines contain 2,4,6- trinitrotoluene (TNT). 2,4-Dinitrotoluene (DNT) is a common manufacturing byproduct in the synthesis and degradation of TNT. The ...
Synthesis and characterization of copper nanoparticles: Architectural morphologies and applications in surface enhanced raman spectroscopy
(2009)
The preparation of copper colloidal suspensions was conducted by three different methods. These methods used wet chemical synthesis, in which a metal salt solution was mixed with a solution containing the reducing agent. ...
Theoretical and experimental vibrational and NMR studies of α and β-RDX
(2008)
Cyclic nitramine hexahydro-1,3,5-trinitro-s-triazine (RDX), is an important energetic ingredient for propellants and explosives. To understand RDX explosive nature, the molecular structure needs to be examined in detail. ...
