Optical properties and energy transfer processes in silver nanocomposite glasses
(2009)
This thesis reports results on the spectroscopic properties and energy transfer processes in silver-doped aluminophosphate glasses. Material preparation was achieved by the meltquenching technique, with tin being used for ...
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 ...
Structure-activity studies, role of transferrin, and gene expression profile of the cytotoxic activity of Ti(IV) complexes in colon adenocarcinoma
(2008-12)
Ligand modification on titanocene dichloride has the potential to produce soluble and stable complexes. As part of our research efforts in the area of titanium-based antitumor agents, we have investigated the cytotoxic ...
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. ...
Effect of the E11 amino acid on the ligand binding in Hemoglobin I from Lucina pectinata
(2007)
Hemoglobin I (HbI) from Lucina pectinata (clam) is a protein that binds and transports H2S to the bacteria in the clam. HbI is one of the few known hemoglobins that carries H2S, toxic gas, in its active site, which contains ...
Effect of the Histidine E7 amino acid in the sulfheme formation of the hemoglobin I from Lucina Pectinata
(2008)
Sulfhemoglobin is a non-functional derivative of hemoglobin known to be produced by exposure to sulfa drugs, air pollution and others. It is formed by the reaction between H2O2, H2S and the heme group in the presence of ...
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 ...
Oxidation reactions of Lucina pectinata hemoglobins: Model system to design heme protein based blood substitutes
(2008)
Today, efforts are focused in the production of a second-generation blood substitutes that minimizes the oxidative stress and the tissue vasoactivity. The infused cell-free hemoglobin’s can act as nitric oxide (NO) scavenger ...
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. ...
