Magnetodynamics of pseudo spin valves investigated using co-planar waveguide and spin torque ferromagnetic resonance techniques
(2017-05-17)Nanocontact spin-torque nano-oscillators (NC-STNOs), based on magnetic multilayers, can generate a wide range of highly nonlinear localized and propagating spin wave modes for use in magnonics. In this thesis, we study ... -
Synchronization Phenomena in Spin Torque and Spin Hall Nano-Oscillators
(2017-05-15)Spin-torque oscillators (STOs) belong to a novel class of spintronic devices and exhibit a broad operating frequency and high modulation rates. STOs take advantage of several physical phenomena such as giant magnetoresistance ... -
Microfluidic devices for single-cell and organ-level studies
(2017-03-01)The process of developing and testing drug candidates is a slow and costly endeavor. The mainstream technologies such as bulk 2D cell culture techniques have been proven insufficient to capture the pharmacokinetics and ... -
Far-infrared conformer-specific signatures of small aromatic molecules of biological importance
(2016)Our understanding of many biological processes requires knowledge about biomolecular structure and weak intra- and intermolecular interactions (e.g. hydrogen bonding). Both molecular structure and weak interactions can ... -
Multi-photon microscopy enhanced: Exploring annular beams and gold nano-particles for improved imaging
(2016-05-09)Laser scanning multiphoton microscopy (MPM) has emerged as a powerful tool for non-invasive three-dimensional imaging of biological tissue. The localized focal region enables confocality without the use of a physical pinhole ... -
Angular dynamics of small particles in fluids
(2015-11-20)This thesis concerns the angular motion of small particles suspended in fluid flows. A small particle experiences a hydrodynamic torque due to the local fluid velocity, and this torque leads to rotational motion. When ... -
Equilibrium statistics of channel-confined DNA
(2015-09-24)This thesis is devoted to the study of DNA molecules in nanochannels. In the last ten years, a large number of studies have been conducted wherein DNA molecules were confined to channels with a width of about 100 nm. These ... -
