“Selectivity of Cinchona Alkoloids for the Synthesis of 3,3-disubstituted Oxindole Derivatives”

The oxindole skeleton bearing a tetrasubstituted carbon at the 3-position is found in many bioactive natural products and pharmaceutically active compounds. The reactions of 3-substituted 2-oxindoles with nitrosobenzene give 3,3-disubstituted oxindole derivatives. It is possible to obtain two different products with different biological activities . Cinchona alkaloids are used as catalysts in this reaction; they can catalyze different types of reactions with changing degrees of efficiency and enantioselectivity. Cinchona alkaloids are environmentally friendly; they are readily available and recoverable. Quantum mechanical calculations were used to determine the most effective cinchona alkoloids for this reaction. In this project three catalysts will be synthesized and the yields and selectivities in the presence of these catalysts will be determined.

“The Use of Cyclodextrins in Drug Solubility and Transfer”

Cyclodextrins in the pharmaceutical industry have been used to enhance the aqueous solubility, physicochemical and physiological stability, and the deliverability of various active pharmaceutical ingredients. Cyclodextrins may form inclusion complexes with various pharmaceutical ingredients through non-covalent, host-guest interactions. Other forms of complexes such as the non-inclusion or association complexes have also been described in literature, and the nature of these interactions generate cyclodextrins as drug delivery carriers. In this study a literature survey about the use of cyclodextrins to enhance the solubility of drugs will be carried out. Some experimental studies about forming thiobarbituric acids and cyclodextrin will be performed.

“Kinetic Studies and Equilibrium Isotherms for The Removal of Cationic Dyes and Copper (II) from Aqueous Solutions by Using Ferrimagnetic Magnetite Nanoparticles”

Several adsorbents are used to remove contaminants from effluents. Among those, magnetite is a special candidate as it is biocompatible and has excellent magnetic properties leading to the possibility of adsorbing contaminants from the effluent and the removal of the entity from the medium by using an external magnetic field. In this study, adsorption mechanisms for the adsorption of two different cationic dyes and Copper (II) ions onto poly(acrylic acid) coated ferrimagnetic magnetite nanoparticles will be investigated by using different equilibrium isotherm models.”

“Study of CO2 Capture over Amine-Modified Mesoporous Silica”

 CO2 is one of the main anthropogenic greenhouse gases, the concentration of which has increased tremendously since the beginning of the industrial revolution. Since the climate change observed on earth was associated with the increasing level of CO2 in the atmosphere, reduction of emissions has become indispensable with the increasing environmental concerns. This project aims a theoretical investigation of CO2 capture over APTMS, MAPS, and DMAPS-modified mesoporous silica structures.

Determination of Amine-Modified Mesoporous Silica Molecular Models” 

CO2 capture over amine-modified mesoporous silica surfaces has received increasing attention due to the critical importance of the subject in achieving the reduction of greenhouse effect. Despite of the numerous mechanistic studies implemented in CO2 scrubbing in aqueous amine solutions, the capture mechanism is still not clear for the adsorption of CO2. One way to investigate the adsorption mechanism of CO2 over amine-modified solid sorbents is to use molecular modeling and the determination of the molecular model to be used is critical for the success of the study. This project aims to determine molecular models for various amine-functionalized MCM-41 adsorbents.
