Superhyrophobicity and structures of adsorbed silane coupling agents on silica and diatomaceous earth
(2016-07)
Superhydrophobic coatings were prepared using fluorosilane treated diatomaceous earth (DE) with either polyurethane or epoxy binders and the results were compared. The water contact angles were studied as a function of the ...
Synthesis and applications of early transition metal oxides
(2014-05)
An optimized synthesis of sodium molybdenum bronze was presented using 1/3 of the expensive Na2MoO4*2H2O buffer as the conventional method. The need for a N2 atmosphere was also eliminated. Further, the reaction time was ...
Thermal analysis of polymers adsorbed on silica and the functionalized mesoporous silica and its application to the adsorption of volatile organic compounds
(2015-07)
The thermal behavior of adsorbed poly(vinyl acetate) (PVAc) on silica was determined using temperature-modulated differential scanning calorimetry (TMDSC). PVAc samples with different molecular masses (260, 170 and 100 ...
I. Steric effects in the synthesis of 2,3-dihydro-4-(1H)-quinolinones by the tandem Michael-SNAr reactionII. Synthesis of Nitrogen heteroarotinoids for anticancer activityIII. Synthetic study of supramolecular compounds
(2013-07)
In the initial project, a one-pot tandem reaction sequence was developed for the preparation of 2,3-dihydro-4-(1H)-quinolinones by a Michael addition-SNAr reaction sequence. The steric environment of the Michael terminus ...
Computational studies of molybdenum oxide clusters and environmental corrosion of iron and zinc
(2014-07)
This dissertation describes two creative activities. The first is a computational study of molybdenum oxide clusters and the other is an experimental study of the corrosion of metals. The first effort covers three topics. ...
Exploration and characterization of new synthesis methods for C60 colloidal suspensions in water
(2014-05)
Buckminsterfullerene, C60, has been used in the production of several commercial products from badminton racquets and lubricants for their mechanical properties to cosmetics and even dietary supplements for their "antioxidant" ...
Preparation and characterization of perfluorooctane sulfonate-intercalated single-walled carbon nanotube ropes and clay-composites
(2012-07)
Scope and Method of Study: The purpose of the first project was to study the anionic intercalation reactions of single walled carbon nanotubes with perfluorooctane sulfonate, and the dispersion of intercalated single walled ...
Genetic algorithms for feature selection and classification of complex chromatographic and spectroscopic data
(2012-12)
A basic methodology for analyzing large multivariate chemical data sets based on feature selection is proposed. Each chromatogram or spectrum is represented as a point in a high dimensional measurement space. A genetic ...
Validation and application of the Purdie assay in the analyses of the major polyunsaturated fatty acids
(2012-07)
Scope and Method of Study:
Polymer adsorption on silica and wettability of graphene oxide surfaces, experiments and simulations
(2016-05)
Among the various classifications of polymer composites, studying polymers adsorbed to a surface such as silica is important due to their numerous applications. Adsorbed polymers usually show different properties than their ...
