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, ...
Supramolecular host-guest interactions of cyclodextrins and calixarenes with niobocene and vanadocene
(2010)
Cyclodextrins (CDs) and calixarenes act as a molecular host to a variety of guests: ions, metal complexes, polar and nonpolar organic molecules. These inclusion complexes have found pharmaceutical applications due to the ...
Synthesis of nanoparticles of iron oxide, silver and gold for photodegradation and detection of 2,4,6-trinitrotoluene
(2013)
Various nano-structured materials were synthesized to be used in the purification and detection of contaminants in water. Iron oxides and extruded polystyrene/TiO2 nanocomposites were synthesized, characterized and evaluated ...
Applications of one-dimensional nanostructures in energy conversion and biomedical sciences
(2011)
This research explores applications of carbon nanotubes in energy and biomedical sciences. For applications in energy, this research reports the synthesis and characterization of one-dimensional silver nanostructures using ...
Near infrared spectroscopic transmission measurements for pharmaceutical powder mixtures and theory of sampling (TOS) applied in pharmaceutical industry quality control (Qc) practices
(2015)
This thesis presents two projects that involve the implementation of near infrared spectroscopy. NIR spectroscopy is a fast and non-destructive spectroscopy that in combination with multivariate analysis is a very useful ...
Development of a methodology to determine drug distribution in polymeric thin film formulations using hyperspectral image analysis
(2013)
This dissertation is focused on the development of analytical methods to determine drug distribution throughout polymeric films using hyperspectral image analysis. The NIR-CI and Raman mapping techniques have been used to ...
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 ...
Sorption of VOCs and PAHs onto recycled tire crumb rubber
(2011)
Sorption of Volatile Organic Compounds (VOCs) (ethylbenzene, toluene and xylene) and Poly Aromatic Hydrocarbons (PAHs) (acenaphthene, acenaphthylene and phenanthrene) by tire crumb rubber (TCR) and its main components were ...
Crystallographic structures of hemoglobin II (HbII) from Lucina Pectinata in the 4–9 pH range
(2011)
Lucina pectinata’s ctenidia contains three hemeproteins: the hydrogen sulfide reactive hemoglobin I (HbI) and the oxygen transporting hemoglobins II and III (HbII and HbIII) that remain unaffected by the presence of H2S. ...
Surface enhanced Raman spectroscopy of vegetative cells and endospores of Bacillus thuringiensis as a model for detection of biothreats
(2012-05)
The development of rapid and efficient techniques for biological detection, identification and classification has a positive impact in fields ranging medical, environmental and industrial microbiology to biological warfare ...
