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 ...
Thermal inkjet technology for the deposition of nanoparticles and Metal-organic framework (Mof): Preparation of sers-active substrates and Mof films for In-situ enhanced raman and infrared detection of harmful contaminants
(2012-12)
The applications of thermal ink-jet printing technology as deposition technique of functional materials such as metal nanoparticles and microporous nickel-oxalate metal organic framework were studied. Highly sensitive ...
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 ...
Laser-Induced growth of nanoparticles and nanostructures
(2011)
The preparation of nanostructures assisted by laser action was studied and successfully accomplished from solution and on surfaces. The synthesized nanostructures were characterized by several microscopy techniques. Silver, ...
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 ...
Desarrollo de método cuantitativo para la determinación del contenido de humedad en el proceso de granulación de un medicamento utilizando la tecnología de infrarrojo cercano
(2011)
The granulation process is one of the most important processes in the manufacture of a pharmaceutical product. This is due to that in this manufacturing step the active ingredient (AI) is mixed with the excipients. One ...
Preparation and study of thin RDX films standards on various substrates deposited by spin coating technology
(2017-05)
The highly energetic material (HEM) hexahydro-1,3,5-trinitro-s-triazine, also known as RDX, has two stable conformational polymorphs at room temperature: α-RDX (molecular conformation of –NO2 groups: axial-axial-equatorial) ...
