Remote infrared spectroscopy detection of highly energetic materials
(2015-12)
An Open-Path Standoff Detection System was designed using a telescope coupled to a EM27 Fourier Transform infrared spectrometer equipped with a mercury cadmium telluride (MCT) cryocooled detector. Samples of highly energetic ...
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 ...
Dependence of active mode remote Ft-Ir sensing on angle of incidence, substrate type and analyte surface concentration
(2013-12)
A standoff detection scheme for a highly energetic material (HEM) and other threat chemicals deposited on substrates as contamination residues using Fourier transform infrared spectroscopy (FTIR) is described. The HEM used ...
Surface enhanced Raman spectroscopy of vegetative cells and endospores of Bacillus thuringiensis as a model for detection of biothreats
(2012-05)

Design and development of remote Raman spectroscopy system for detection of hazardous compounds
(2012-11)
Remote Raman detection has become a powerful analytical technique for detection of hazardous compounds in situ and without sample preparation at distances away from the observation site. This study describes the design, ...
Synthesis and surface modification of metallic nanoparticles: Sensitivity, influence of shape, concentration and excitation wavelength on chemical detection by Sers
(2010-05)
Surface-Enhanced Raman Spectroscopy (SERS) is a powerful spectroscopic technique that can be used for detecting analytes at very low concentrations. In SERS, the intensity of vibrational signatures can be enhanced by factors ...
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 ...
Open path FTIR standoff detection of high explosives on aluminum substrates
(2010)
An Open-Path Standoff Detection System was designed using a telescope coupled to a EM27 Fourier Transform infrared spectrometer equipped with a mercury cadmium telluride (MCT) cryocooled detector. Samples of highly energetic ...
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 ...
