The Investigation of Titanium Dioxide Nanoparticle Films Created through Electrophoretic Deposition (2011-04-14)Department: PhysicsThe development of thin ceramic films has increased in importance throughout the science and industry communities. The distinct characteristics of the strength, transmittance in the visual spectrum, antimicrobial properties, ...
-
(2016-12-12)Department: PhysicsOptical nanostructures are becoming an increasingly important aspect of modern technology. As a result high-resolution experimental techniques as well as nanoscale computational methods have become increasingly important ...
-
(2006-12-05)Department: PhysicsThe coolest white dwarfs known with effective temperatures below 5000K are among the oldest stars in the Milky Way. As they define the cutoff in the white dwarf luminosity function, they may be used as cosmochronometers. ...
-
(2012-07-30)Department: PhysicsDetailed studies of the spectral energy distributions (SEDs) of young stars can reveal much about their basic properties and their circumstellar material. Previous work suggests that the magnetic interactions of its ...
-
(2015-07-14)Department: PhysicsGalaxy interactions play a critical role in the growth and evolution of galaxies. While galaxy mergers are known to transform galaxies morphologically and kinematically in a myriad of ways, not all interactions lead to a ...
-
(2010-04-16)Department: PhysicsT Tauri stars, being pre-main sequence and solar mass, tell us what our Sun was like when it was very young. T Tauri stars and their protoplanetary disks are ideal astrophysical laboratories for studying the solar system ...

The solid-solid phase transition in vanadium dioxide thin films: synthesis, physics and application (2011-04-27)Department: PhysicsTHE SOLID-SOLID PHASE TRANSITION IN VANADIUM DIOXIDE THIN FILMS: SYNTHESIS, PHYSICS AND APPLICATION JOYEETA NAG DISSERTATION UNDER THE DIRECTION OF PROFESSOR RICHARD F. HAGLUND, JR. This dissertation is devoted to the ...
-
(2021-07-08)Department: PhysicsThe non-trivial vacuum structure in QCD leads to addition of an extra term to its Lagrangian. This term serves as the source of CP violation in QCD. Introducing a new pseudoscalar particle called axion can retain the CP ...
-
(2015-07-06)Department: PhysicsDiffusion MRI provides a non-invasive means to characterize tissue microstructure at varying length scales. Apparent diffusion coefficients (ADCs) of tissue water may be measured at relatively long diffusion times with ...
-
(2015-03-26)Department: PhysicsThis thesis uses two complementary techniques to mine the Sloan Digital Sky Survey (SDSS) data to search for stars that are unbound to the Milky Way. A significant fraction of a galaxy's light may come from a population ...
-
(2021-07-15)Department: PhysicsThe successful isolation and characterization of graphene opened a new dimension for experimental materials research. And though graphene possesses an assortment of attractive mechanical, optical, and electrical properties ...
-
(2012-03-31)Department: PhysicsI identified and used a large catalog of ultra-wide binaries to investigate observationally two related questions in low-mass star astrophysics: (1) What is the frequency and distribution of ultra-wide binary systems, and ...
-
(2008-11-18)Department: PhysicsSince the discovery of giant magnetoresistance (GMR), the spin of the electron has attracted significant interest in the field of microelectronics. Spintronics, which involves manipulating both quantum spin states of ...
-
(2008-07-27)Department: PhysicsThis dissertation is mainly focused on the femtosecond pump probe spectroscopy of the (6, 5) single wall carbon nanotubes (SWNTs). There are three advantages in this experiment, first, we upgrade the optical parametric ...
-
(2020-10-28)Department: PhysicsIn this dissertation we seek to present a comprehensive fluence and wavelength dependent ultrafast pump-probe transmission study of graphene supported on a soda-lime glass substrate for a range of pump fluences that enable ...
-
(2017-03-27)Department: PhysicsAs astronomy expands into the era of Big Data, with increased data capture and storage capabilities and enhanced computing power, the large data sets that will become accessible need to be properly understood to maximize ...
-
(2019-07-18)Department: PhysicsThe Universe is comprised of structures on all scales, ranging from stars and planets to galaxies and clusters. These structures form part of a much bigger web-like structure built with systems of galaxies, filaments, ...
-
(2009-07-28)Department: PhysicsThe goals of the research presented in this dissertation are to better understand the characteristics of the X-ray emitting plasmas of young stars and the physical mechanisms that produce the emission. We seek to achieve ...
-
(2013-04-17)Department: PhysicsAsteroids are remnants of the formation of the Solar System and provide insight into its formation, evolution and how life may have begun. An important issue is determining which meteorite composition is representative ...
