Polyelectrolytes can be used in a variety of forms from Layer-by-Layer assembled thin films to spun polyelectrolyte complex as free-standing membranes. The Layer-by-Layer methodology is used to adsorb oppositely charged polyelectrolytes...
A key challenge for modern chemistry is the production of mesoscopic complexity and hierarchical order to ultimately bridge the gap between the molecular world and functional microdevices. As proof of concept, nature shows unambiguously...
This dissertation presents and evaluates the structure-sensitive optical and electronic properties of gold nanostructure systems: plasmonic gold nanoparticle networks and monolayer-protected gold nanoclsuters. Plasmonic nanoparticle...
Inorganic precipitate membranes play an important role in chemobrionics and origin of life research. They can involve a range of catalytic materials, affect crystal habits, and show complex permeabilities. Microfluidic flows are a...
Living organisms engineer complex architectures that address many of their survival needs such as strength, flexibility, self-healing properties, and the fast transport of resources. The typical starting materials are abundant and...
Structural biology has been successful in the characterization of soluble protein, which has given insight in the inner working of several thousands of proteins. However, structural characterization of proteins has been limited in two...
The role of charge density in polyelectrolyte multilayer coatings used in 2-D cell culture was investigated in this dissertation. First it is important to comprehend that cells do not attach directly to surfaces, they attach to proteins...
My dissertation, The Cairo Letters, is a collection of poems that draws largely on the epistolary tradition. One section describes a series of letters I received from a first love living in Cairo, Egypt. They were long and lonesome and...
The work in this dissertation presents microfluidic platforms developed for the evaluation of islet function. Pancreatic islets of Langerhans release glucagon and insulin to maintain blood glucose levels, and the release of these...
The adsorption of proteins in biomedical implants, like catheters, cardiac pacemakers, and blood-contacting sensors, 1–3 could cause these devices to malfunction at long term. Therefore, the understanding of proteins’ adsorption onto...
This dissertation presents structure-specific descriptions of optical properties and electronic energy relaxation dynamics of structure precise monolayer-protected gold clusters (MPCs) and narrow size distributed semiconductor...
Polyelectrolytes are highly charged polymers compensated by small counterions. Based on the type of charge, a polyelectrolyte can be either polycation or polyanion. When mixing two oppositely charged polyelectrolytes in aqueous solution, ...
Global demand for clean sustainable energy is growing with the planet's population. While fossil fuels are the current standard, many are looking to the nearly endless energy supplied by the Sun. Because of the potential cost benefit...
The interactions of charged polymers, polyelectrolytes, on surfaces and in solution have gained a lot of attention throughout the years. Depositing alternating layers of oppositely charged polyelectrolytes forms multilayers, PEMUs. Their...
Photon upconversion (UC), especially through the process of triplet-triplet annihilation (TTA), is capable of combining two photons into one higher energy photon which could be captured in applications such as photovoltaics, ...
Intermetallic magnetic materials, such as SmCo5 and Nd2Fe14B, play important role in our daily lives via their use in many high-tech devices and technologies. Understanding the interplay between the crystal structure, electronic...
Polyelectrolyte complexes have gained great attention over the past few decades for their applications in materials science, engineering, and medicine. They can be assembled into thin films via the layer-by-layer deposition of oppositely...
Owing to the onset of applications of technological devices in our everyday life, lanthanide elements are becoming continuously important. Traditionally known as rare earth metals, lanthanides (Ln) are categorized as critical materials...
This dissertation is divided into two parts, both of which describe the synthesis of various organic molecules. Much of the work is already published, as noted where appropriate in the chapter headings. The first part of this work covers...
