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, ...
Nonlinear Optical Enhancement from Aggregate and Ensemble Effects in Organic Systems.
(2011)
Organic optoelectronics provide several advantages over traditional Si based systems. These advantages are typically cost, ease of manufacturing, and environmental impact. One area of particular interest in the field of ...
Global Hall Magnetohydrodynamics and Coupled Fluid-Kinetic Simulations of Mercury's Dayside Magnetopause Dynamics
(2023)
Mercury possesses a miniature yet dynamic magnetosphere driven primarily by the solar wind through magnetic reconnection. Because Mercury is 60% closer to the Sun than Earth, its magnetosphere routinely experiences stronger ...
Coherence Recovery in Random Environments Using the Autoproduct
(2023)
The study of wave propagation is a mature field of research with numerous avenues of theoretical, numerical, and experimental investigation. A prominent application is remote sensing, where recorded acoustic or electromagnetic ...
Device Physics and Applications of Ternary Organic Photovoltaics
(2023)
Organic photovoltaics (OPVs) are emerging as an attractive candidate for solar energy harvesting due to their advantages in environmental compatibility, low-cost, flexibility and transparency. The past few decades have ...
Ionic Conductive and Highly‐Stable Interface for Alkali Metal Anodes
(Wiley Periodicals, Inc., 2022-08)
Alkali metals are regarded as the most promising candidates for advanced anode for the next‐generation batteries due to their high specific capacity, low electrochemical potential, and lightweight. However, critical problems ...
High-Throughput Cellular Heterogeneity Analysis in Cell Migration at the Single-Cell Level (Small 6/2023)
(Wiley Periodicals, Inc., 2023-02)
High-Throughput Cellular Heterogeneity Analysis in Cell Migration at the Single-Cell Level
(Wiley Periodicals, Inc., 2023-02)
Cancer cell migration represents an essential step toward metastasis and cancer deaths. However, conventional drug discovery focuses on cytotoxic and growth-inhibiting compounds rather than inhibitors of migration. Drug ...
Plume-Surface Interactions due to Spacecraft Landings and The Discovery of Water on Mars.
(2010)
Pulsed supersonic jets or rocket plumes have different surface flow physics than steady jets, in particular in tenuous atmospheres such as that of Mars where jets are collimated over large distances compared to their ...
Novel Imaging Systems Using Nanophotonic Devices
(2021)
Novel technologies and innovations lead to new applications. This dissertation demonstrates new applications enabled by novel nanophotonic devices. I will describe two nanophotonic devices: hyperbolic metamaterial and ...
