(2020-03-31)Department: ChemistryColloid quantum dots (QDs) are semiconductor nanocrystals that can be tuned to emit specific wavelengths of light based upon their size. Maintaining long-term brightness of QDs is crucial towards their applications. Achieving ...
-
(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 ...
-
(2014-11-25)Department: Interdisciplinary Materials ScienceThree previously unreported photo-carrier relaxation pathways are presented and discussed in GaAs-based systems. In bulk GaAs, a transient bleach of the spin-split exciton transition 1s->2p is reported following photo-excitation ...
-
(2010-01-21)Department: ChemistryDue to the declining availability of fossil-fuels and the adverse environmental affects of the same, the world has begun a move to more efficient and longer-lasting solid-state lighting. Ultrasmall CdSe nanocrystals ...
-
(2018-03-30)Department: Interdisciplinary Materials ScienceZinc oxide is a wide band gap (3.37 eV) semiconductor with a high exciton binding energy (60 meV), of interest for optoelectronic applications due to both its ultraviolet (UV) and visible emissions. This dissertation shows ...
-
(2021-03-06)Department: ChemistryUmpolung amide synthesis (UmAS) exploits the unique properties of an α-halo nitroalkane in its reaction with an amine to produce an amide. The “umpolung” moniker reflects its paradigm-breaking C–N bond formation on the ...
-
(2014-07-22)Department: ChemistryTraditional amide synthesis employs a nucleophilic amine, which is reacted with an electrophilic activated carboxylic acid or carboxylic acid surrogate. Recently, colleagues in the Johnston lab introduced an unconventional ...

(Asociación Canadiense de Hispanistas, 2007)A pesar de la creciente ubicuidad de la tecnología digital, la crítica literaria apenas ha explorado de manera práctica las posibilidades expositivas del hipertexto cibernético, especialmente en lo que hace a la utilización ...
-
(2021-06-15)Department: FrenchIn this dissertation, close readings of twenty-first century texts by Annie Ernaux, Nina Bouraoui, Maïssa Bey and Chloé Delaume expose the role of language and the possibilities offered by autofictional space in the ...
-
(2021-03-24)Department: SociologyUnequal access to important resources in the urban built environment has been a significant social problem under study by social scientists. Guided by an environmental justice framework, this mixed-method dissertation takes ...

-
(Center for American Progress, 2014)Since the 2008 financial crisis, the problem of financial institutions being "too big to fail," or TBTF, has been front and center in the public debate over the reform and regulation of the financial industry. Commentators ...
-
(2010-03-18)Department: Cell and Developmental BiologyCoordinated movement depends on specific connections between neurons, yet mechanisms that govern synaptic specificity are poorly understood. The simple, well-defined motor circuit of the nematode, C. elegans provides an ...
-
(2017-09-08)Department: Civil EngineeringProbabilistic performance assessment evaluates a system’s capability to accomplish the required functions under uncertainty. The results of probabilistic performance assessment can be used to support decision making such ...
-
(2008-04-11)Department: Mechanical EngineeringModeling and simulation have played an increasingly important role in the design and analysis of engineering systems. High-consequence decisions are often informed strongly by numerical results obtained through the use ...
-
(2022-08-04)Department: PsychologyIntolerance of uncertainty (IU) is the tendency to react negatively to uncertain situations due to negative beliefs about uncertainty. IU demonstrates robust associations with symptoms of obsessive-compulsive disorder ...
