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 ...
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 ...
Adsorption of Hexahydro-1,3,5-Trinitro-1,3,5-Triazina (RDX) on soil and clay mineral surfaces
(2008)
Hexahydro-1,3,5-trinitro-1,3,5-triazine (RDX) is an energetic compound that is commonly used as a military explosive. Studies indicate that nitroamines compounds, particularly those exhibiting several NO2 groups or other ...
Observation of enhanced Raman scattering as a result of coupling between localized plasmons and surface polariton waves associated with metal-semiconductor nanocomposites
(2011-05)
We report the observation of enhanced Raman scattering as a result of the coupling between the localized surface plasmon (LSP) of metal nanoparticles (NP) and the surface plasmon polariton (SPP) associated with a thin metal ...
X-ray photoelectron spectroscopy (XPS) study of Hexahydro-1,3,5-Trinitro-S-Triazine (RDX)
(2007)
Energetic materials are used as explosives component of landmines, plastic explosives
(C-4), and home made bombs, among others. Hexahydro-1,3,5-trinitro-s-triazine (RDX) is a
secondary explosive, which is the main ...
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 ...
Experimental and theoretical study of solubility of 1, 3, 5-trinitrohexahydro-S-triazine (Rdx) In alcohols
(2010)
The solubility of 1,3,5-trinitrohexahydro-s-triazine (RDX) in different alcohols were measured by HPLC, DSC, GC/MS, and NMR. The conformation of RDX in acetone-D6 solution was verified by vibrational studies using Raman ...
Separation, identification, and quantification of explosives using thin layer chromatography coupled to mid-infrared laser spectroscopy
(2019-05-10)
The need for rapid instrumentation and methods for detection and identification of chemical and biological threat agents in national defense and homeland security settings has become an ever more important issue in modern ...
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 ...
