New Methods for Terahertz and Ultrafast Infrared Spectroscopy of Biological Materials and Graphene Buffer Layer
(2019)
The development of advanced optical spectroscopy has always been a frontier in optics and material science. This dissertation develops several new methods for terahertz (THz) and infrared spectroscopy and presents their ...
Probing Heat Transport and Energy Conversion at the Atomic and Single Molecule Scale
(2018)
The study of heat transport and energy conversion constitutes an important subject in modern physics and engineering research. The widely-applied Fourier’s and Planck’s laws have proven to be very useful to describe heat ...
Efficient Algorithms for Light Transmission, Focusing and Scattering Matrix Retrieval in Highly Diffusive 3D Random Media
(2018)
Wavefront shaping provides an increasingly appealing avenue for imaging and other applications that require controlling electromagnetic waves passing through complex and disordered media. Indeed, these techniques allow ...
Surface Dimer Engineering and Properties of GaAs(N)(Bi) Alloys
(2018)
Due to the significant bandgap narrowing induced by dilute fractions of N and Bi in III-V semiconductors, emerging dilute nitride-bismide semiconductor alloys are of significant interest for long-wavelength applications ...
The Study of CO2 Conversion in a Microwave Plasma/Catalyst System.
(2012)
The continual and increasing use of fossil fuels throughout the world has advanced concerns of atmospheric carbon dioxide (CO2) concentrations, causing a swell of scientific effort to mitigate the predicted effects of ...
Theoretical and Experimental Study of Fuel Injector Tip Wetting as a Source of Particulate Emissions in Gasoline Direct-Injection Engines
(2019)
Gasoline fuel film deposited on the tip of a fuel injector, i.e. injector tip wetting, has been identified as a significant source of particulate emissions at some operating conditions of gasoline direct-injection engines. ...
Hsp70 chaperone Proteins and their Interactions with Various Drugs as Studied by Nuclear Magnetic Resonance.
(2011)
Chaperone proteins and their cochaperones are perhaps one of the most intriguing systems for investigation. Ubiquitous in nature, they can be found in every organism and that perhaps is the reason that their sequence shows ...
Regulating Gene Expression Through DNA Mechanics: Tightly Looped DNA Represses Transcription.
(2010)
It is now widely accepted that the mechanical state of DNA can play a major role in regulating the activity of RNA polymerase (RNAP). Not only have the global levels of supercoiling been shown to regulate transcription, ...
