The ability to control the motion of particles and cells in microchannels has been a center of fascination since the advent of microfluidics. Entire fields have been created in order to accomplish separation, volume reduction ...

Within the field of optics, one of the topics being currently investigated with considerable interest is that of plasmonics, which refers to the use of surface plasmons on metallic nanostructures to manipulate light. It ...

This dissertation describes methodology that significantly improves the state of femtosecond laser writing of metals. The developments address two major shortcomings: poor material quality, and limited 3D patterning ...

In protein NMR spectroscopy, homonuclear mixing pulses are used to reveal correlations amongst chemically bonded nuclear spins.

This thesis explores mechanical behavior of microelectronic devices and lithium-ion batteries. We first examine electromigration-induced void formation in solder bumps by constructing a theory that couples electromigration ...

This thesis explores a novel methodology to fabricate three dimensional (3D) metal-dielectric structures, and two dimensional (2D) graphite layers for emerging metamaterials and graphene applications. The investigations ...

This dissertation explores strategies for improving photolvoltaic efficiency and reducing cost using femtosecond-laser processing methods including surface texturing and hyperdoping. Our investigations focus on two aspects: ...

This thesis investigates the mechanical behavior of electrodes in Li-ion batteries. Each electrode in a Li-ion battery consists of host atoms and guest atoms (Li atoms). The host atoms form a framework, into which Li atoms ...

Cardiovascular stents are one of the most widely implanted medical devices, with over 1 million implanted each year in the United States alone. While stent failure modes of restenosis and thrombosis have been widely examined, ...

Metallic nanostructures that employ localized surface plasmon resonances to capture or radiate electromagnetic waves at optical frequencies are termed "plasmonic optical antennas". These structures enhance light-matter ...
