The main objective of this project is to develop a polymer based near infrared (NIR) particle that can serve as both, diagnostic and therapeutic agents, for fighting cancer. Specifically these particles will be designed to have high-contrast, high signal to noise ratios, long in vivo circulation lifetimes, and facilitat…
The interaction of magnetic fields generated by large superconducting coils has multiple applications in space, including actuation of spacecraft or spacecraft components, wireless power transfer, and shielding of spacecraft from radiation and high energy particles. These applications require coils with major diameter…
Characterization of catalyst materials and unraveling of catalytic processes requires a multitude of complementary and in situ techniques. In this work, analytical methods are developed based on X-ray microscopy: quasi in situ tomography to study honeycomb aging and ptychography to image nanoparticles. Moreover, devic…
I owe a great debt to the graduate students who have gone before me in this lab especially Aaron Van Pelt and Jason Mance for their Labview programs and training in the day to day operation of femtosecond lasers respectively.Thank you to a previous post doc A. V. V. Nampoothiri for his THz data.I also want to thank th…
Phthalates are chemicals used as plasticizers in various plastics and consumer products, including PVC products, personal care products and pharmaceutical applicants. These chemicals may migrate into the environment, food and water and enter the human body via ingestion and inhalation, but also through the skin. Epide…
The characteristics of SiO2-Al2O3 supports were tuned by three strategies in order to achieve highly dispersed, especially single-atom Pt sites using for CO oxidation or propane dehydrogenation (PDH). The strategies include incorporation of χ-Al2O3 and Si into γ-Al2O3 via solvothermal, variation of SiO2 content of Si-…
Increasing energy density of electrochemical capacitors (ECs) is crucial for their applications in energy storage devices requiring short peak power pulses as well as long-term operation. ECs are operated via two primary charge mechanisms, that is, the electrochemical double-layer capacitance and the pseudocapacitance…
To meet the growing demand for energy and to reduce the depletion of fossil resources, technology for the harnessing of renewable energy is urgently needed. Among all the renewable energies, solar energy is one of the most clean, abundant and sustainable energy sources that can help to solve the world energy consumpti…
I am deeply grateful for the many discussions and their invaluable
Polycrystalline Bi doped spinel BixCo2-xMnO4 compounds were prepared by solid state reaction route. Room temperature neutron diffraction study reveals that all the compounds are formed in cubic phase and there is no change in the crystal structure due to Bi doping and the compound has cubic structure with Fd-3m space…
Im Rahmen dieser Arbeit wurde das Tablettierverhalten von Trockengranulaten aus Hilfsstoffen mit unterschiedlichen Kompressionsverhalten in Relation zur Direkttablettierung naher untersucht. Dabei konnte ein masgeblicher Einfluss des Schmiermittels auf die Ergebnisse der Tablettierung der Trockengranulate gezeigt werd…
Rendering photo-realistic animal fur is of practical importance in many computer graphics applications. In the past, the visual appearance of specific fiber types have been studied, and various reflectance models have been proposed. These models, however, lack either physical accuracy or versatility to produce the wid…
Este trabalho trata sobre a trabalhabilidade de misturas asfálticas mornas (WMA - do inglês Warm Mixes Asphalt), que são misturas produzidas em temperaturas inferiores às tipicamente utilizadas nas misturas asfálticas à quente (HMA – do inglês Hot Mixes Asphalt). Para se tornar possível a mistura a temperaturas reduzi…
Ziel der vorliegenden Arbeit war die Herstellung und Charakterisierung von orodispersiblen Polymerfilmen mit schwer wasserloslichen Modellarzneistoffen. Die Modellarzneistoffe wurden hinsichtlich ihrer Loslichkeit in Wasser und der therapeutischen Dosierung gewahlt. Tadalafil und Loperamid wurden als niedrigdosierte A…
Copper has been used as a broad-spectrum biocide for centuries, showing effective antimicrobial performance against bacteria, fungi and viruses. Among various forms of copper, copper nanoparticles is attracting particular attention because of its high surface area and crystal morphology that will enhance copper antimi…
The size and performance of integrated circuits have been following Moore’s law to continuously shrink and progress over the past decades while on-chip inductors have seen little advancements. This work proposes several unique approaches in the integrated magnetic cores for high frequency micro inductor developments,…

A central paradigm for classifying the phases of correlated electron systems is their \nsymmetry. Having the ability to controllably tune symmetry-related properties of \nthe system is therefore a powerful probe. \n \nIn this thesis experiments on quasi-two-dimensional metals Sr₃Ru₂O₇ and Sr₂RuO₄ \nare reported, where…
Trilayer polypyrrole microactuators that can operate in air have previously been developed. They consist of two outer layers ofthe electroactive polymer polypyrrole (PPy) and one inner layer of a porous poly(vinylidene flouride) (PVDF) membranecontaining a liquid electrolyte. The two outer layers of PPy are each conne…
Bulk heterojunction (BHJ) organic solar cells (OSCs) have many promising characteristics such as lower material cost, simple processing at ambient conditions and the possibility of roll-to-roll printing. The present major limitation of OSCs is relatively low power conversion efficiency (PCE) which is mainly caused by…
