Combination Therapy: Parp Inhibitor Synergizes The Therapeutic Efficacy Of Doxorubicin In The Treatment Of Prostate Cancer, Momin Ansare
Combination Therapy: Parp Inhibitor Synergizes The Therapeutic Efficacy Of Doxorubicin In The Treatment Of Prostate Cancer, Momin Ansare
Electronic Theses & Dissertations
Men are most susceptible to prostate cancer in the United States. The general treatment options include surgery, hormone therapy, chemotherapy, and radiation therapy. But in recent days, the nanoformulation have shown promising applications in overcoming the drawbacks of the currently available treatment options. To complement, we tried to enhance the capability of the nanoparticle formulation by loading them with a novel drug combination for the treatment of prostate cancer. Herein, we synthesized folate conjugated iron oxide nanoparticles encapsulated with doxorubicin and olaparib for imaging and targeted treatment of prostate cancer. Both drugs are approved by FDA for clinical cancer treatment. …

Synthesis Of Doxorubicin-Based Prodrug And Activatable Mr Nanoprobe For The Imaging And Treatment Of Cancer, Bayan Dous
Electronic Theses & Dissertations
Magnetic Resonance Imaging (MRI) is increasingly being used as a diagnostic tool for cancer. We propose a novel molecular probe, Gadolinium-DTPA disulfide-bonded Doxorubicin (Gd-DTPA-SS-Doxo) encapsulated in iron oxide which could provide a dual modality for detecting malignant growth while simultaneously targeting treatment options. We first synthesized Gd-DTPA-SS-Doxo followed by encapsulation within the poly (acrylic acid) (PAA) coating of iron oxide nanoparticle (IONP), producing a nanoprobe (IO-Gd-DTPA-SS-Doxo) with quenched longitudinal spin lattice magnetic relaxation (T1). After receptor-mediated internalization, Gd-DTPA-SS-Doxo is released from the nanoprobe’s polymeric coating due to the acidic microenvironment of the tumor. When the molecular probe is subjected to …
A Facile Method To Synthesize Bi-Functional Nanostructured Nickel Compounds For Energy Storage And Water Splitting Applications, Nawaf Albeladi
A Facile Method To Synthesize Bi-Functional Nanostructured Nickel Compounds For Energy Storage And Water Splitting Applications, Nawaf Albeladi
Electronic Theses & Dissertations
In recent years, the increasing demands for clean, efficient, and renewable energy have triggered researchers to increase their effort to develop multi-functional materials for energy applications. Supercapacitors, among the comparative energy storage devices, have attracted considerable attention due to their high energy storage capacity, fast charge-discharge capability, long cycle life, and high power density. Transition metal oxides and sulfides are being used as materials for supercapacitor applications due to their excellent conductivity, high electrochemical properties, and large theoretical energy storage capacitance. On the other hand, among the numerous energy techniques, water splitting has become one of the most important technologies …

An Abstract of the Thesis by
Ahlam Alghamdi
The main objective of this study is to synthesize nanostructured cobalt oxide decorated on polypyrrole using a facile method for energy applications. For this, polypyrrole was first synthesized using a chemical polymerization method. In the second step, a varying amount of cobalt oxide was decorated on polypyrrole using a hydrothermal process. The synthesized materials were structurally and electrochemically characterized. It was observed that the electrochemical properties of the composites depend on their composition. The …
Flame Retardancy Of Ferrocene Incorporated Epoxide, Sultan Alanazi
Flame Retardancy Of Ferrocene Incorporated Epoxide, Sultan Alanazi
Electronic Theses & Dissertations
Epoxy resins are thermosetting resins that are used in a variety of applications such as electrical and electronic devices. However, epoxy resins can be inherently flammable. To circumvent this problem, epoxy resins were prepared by incorporating ferrocene carboxylic acid into the epoxy prior to thermal setting, as a flame retardant. Ferrocene carboxylic acid was prepared by condensing o-chlorobenzoyl chloride with ferrocene followed by hydrolysis. The synthesized ferrocene carboxylic acid was characterized by 1H-NMR spectroscopy, 13C-NMR spectroscopy, and FT-IR spectroscopy. Epoxy films were then prepared by reacting ferrocene carboxylic acid (10, 15, and 20% by wt) with bisphenol A …
A Detailed Study Of Novel High-Performance Bromine And Phosphorus Based Reactive Flame Retardants In High-Quality Bio-Polyol Based Rigid Polyurethane Foams, Sanket Bhoyate
Electronic Theses & Dissertations
Structural fire is one of the most catastrophic issues related to human safety observed from reports of National Fire Protection Association of United States in past years. Polyurethanes are one of the important structural material used as thermal insulation in housing. They are also used in automotive, construction, medical, packaging, furniture, thermal, electrical, and vibration insulation. Considering this, we have synthesized bio-based polyurethane foams using limonene-based polyol, isocyanates, and other compounds. Flame retardancy was imparted using reactive flame retardant polyols. Firstly, flame retardancy test was performed on the foams using two novel aliphatic and two novel aromatic bromine-based synthesized reactive …

Targeted Triple Drug Regimen For The Treatment Of Prostate Cancer, Tanuja Tummala
Electronic Theses & Dissertations
Prostate cancer is the most common amongst men. According to ACS 2018 statistics, about 164,690 new cases appear and 29,430 deaths occur. Nearly 6 in 10 cases are diagnosed in men over 50 years of age and often there are no early symptoms. The treatment options include surgery, chemotherapy, hormonal therapy and/or radiation and it can often be treated successfully. However, the poor management and adverse effects demanded ways to find better treatment option. Towards the development of a personalized medicine for prostate cancer treatment, we proposed to design prostate cancer targeting magnetic nanoplatform. This integrates various key components such …

Highly Flame Retardant And Bio-Based Rigid Polyurethane Foams Derived From Orange Peel Oil, Chunyang Zhang
Electronic Theses & Dissertations
Polyurethane is an important class of polymer which is being used for various industrial applications in the form of rigid foams, flexible foams, thermoplastic, elastomer, coating, and adhesive. Especially there is a huge market for rigid polyurethane foams for their applications as thermal insulating material in building and housing. In general, polyurethanes are prepared using polyols and diisocyanates. Most of the polyols used by industries are petrochemical based. In this project, a novel polyol from an orange peel oil-based derivative, limonene dimercaptan, was synthesized using one step photochemical thiol-ene reaction. The synthesized polyol was used to prepare flame retardant polyurethane …
Characterization Of Polymers Containing Ferrocene And Imidazole With Density Functional Theory, Eric Mullins
Characterization Of Polymers Containing Ferrocene And Imidazole With Density Functional Theory, Eric Mullins
Electronic Theses & Dissertations
Electrochemical and UV-Vis studies on these polymers in the presence of aqueous solutions containing metal ions have revealed significant modifications in the electrochemical properties and absorption spectra. These modifications in electrochemical properties could be attributed to the ability of the imidazole to coordinate with metal ions, increasing its electron deficiency and enhancing oxidization of the nearby ferrocene moiety if it is in close proximity with imidazole. However, the mechanism of interaction between the imidazole and metal ions, as well as the equilibrium geometry of the resulting polymer-metal ion complex is unknown.
In this thesis, density functional theory (DFT) was used …
