Investigation Of Microwave-Assisted Synthesis Of Palladium Nanoparticles Supported On Fe3o4 As Efficient Recyclable Magnetic Catalysts For Suzuki-Miyaura Cross-Coupling, Hany A. Elazab May 2019

Investigation Of Microwave-Assisted Synthesis Of Palladium Nanoparticles Supported On Fe3o4 As Efficient Recyclable Magnetic Catalysts For Suzuki-Miyaura Cross-Coupling, Hany A. Elazab

Chemical and Biochemical Engineering Faculty Research & Creative Works

In this research, a facile and reproducible approach was implemented for the synthesis of palladium nanoparticles supported on Fe3O4 with remarkable activity as an ideal catalyst for Suzuki-Miyaura cross-coupling. Magnetite supported Pd nanoparticles reveal high activity in Suzuki-Miyaura coupling reactions since they could be recycled up to seven times with the same high catalytic activity. This adopted method of catalyst synthesis has many advantages, including reproducibility and the reliability of the adopted synthetic method. The produced catalyst has unique magnetic properties to facilitate catalyst recovery from the reaction mixture by using a strong magnet as an external …

Functionalization Of Iron Oxide Nanoparticles And The Impact On Surface Reactive Oxygen Species Generation For Potential Biomedical And Environmental Applications, Trang Mai Jan 2019

Functionalization Of Iron Oxide Nanoparticles And The Impact On Surface Reactive Oxygen Species Generation For Potential Biomedical And Environmental Applications, Trang Mai

Theses and Dissertations--Chemical and Materials Engineering

Iron oxide nanoparticles (IONPs) have been widely studied for a variety of applications, from biomedical applications (e.g., cell separation, drug delivery, contrast agent for magnetic resonance imaging and magnetically mediated energy delivery for cancer treatment) to environmental remediations (e.g., heavy metal removal and organic pollutants degradation). It has been demonstrated that IONPs can induce the production of reactive oxygen species (ROS) via Fenton/Haber-Weiss reactions which has been shown to be one of the key underlying mechanisms of nanoparticles toxicity. This inherent toxicity of nanoparticles has been shown to enhance the efficacy of traditional cancer therapies such as chemotherapy and radiation. …


Development Of Magnetic Nanocomposite Materials As Reusable Adsorbents For Chlorinated Organics In Contaminated Water, Angela Gutierrez Jan 2019

Development Of Magnetic Nanocomposite Materials As Reusable Adsorbents For Chlorinated Organics In Contaminated Water, Angela Gutierrez

Theses and Dissertations--Chemical and Materials Engineering

The constant growth in population worldwide over the past decades continues to put forward the need to provide access to safe, clean water to meet human needs. There is a need for cost-effective technologies for water and wastewater treatment that can meet the global demands and the rigorous water quality standards and at the same maximizing pollutant efficiency removal. Current remediation technologies have failed in keeping up with these factors without becoming cost-prohibitive. Nanotechnology has recently been sought as a promising option to achieve these goals. The use of iron oxide magnetic nanoparticles as nanoadsorbents has led to a new …
