Ferrocene-based molecular electronics and nanomanufacturing of Pd nanowires.
(2007-11-27)Two test structures were tried out for molecular junction formation and subsequent I-V characteristics measurements. One is formed by insertion of certain dithiol molecules into an alkanethiol self-assembled monolayer ... -
Flexibility and Control of Protein-DNA Loops
(World Scientific Publishing Company, 2006-10)Protein-DNA loops are essential for efficient transcriptional repression and activation. The geometry and stability of the archetypal Lac repressor tetramer (LacI)-DNA loop were investigated using designed hyperstable loops ... -
Fluorescence and NMR Studies of the Role of Metal Ions in HIV-1 Genomic RNA Dimerization and Maturation
(2009)The dimerization initiation site (DIS) is an essential RNA element responsible for dimerization of HIV-1 genomic RNA through a kissing loop interaction. The DIS loop contains six auto-complementary nucleotides stabilized ... -
Fluorescence Correlation Spectroscopy Studies of DNA Binding to Catanionic Surfactant Vesicles
(2010)Catanionic vesicles, made from mixtures of oppositely charged surfactants, have potential in drug delivery and gene therapy applications. Fluorescence correlation spectroscopy (FCS) was utilized to study the electrostatic ... -
Fluorescent Carbon Nanotubes as Molecular Sensors and Color-Center Hosts
(2022)This thesis demonstrates the application of single-walled carbon nanotubes (SWCNTs) as single-digit nanopores for molecular sieving and addresses a fundamental challenge pertaining to controlled synthesis of organic ... -
FLUORESCENT ULTRASHORT NANOTUBES FROM DEFECT-INDUCED CHEMICAL CUTTING
(2020)Ultrashort single-walled carbon nanotubes (SWCNTs) that fluoresce brightly in the shortwave infrared shows great potentials in bioimaging, sensing and enabling room-temperature, solid-state single-photon sources. However, ... -
From Structure to Thermodynamics with Local Molecular Field Theory
(2013)A fundamental goal of statistical mechanics is to connect a description of the intermolecular interactions and the accompanying microscopic structural details of a molecular system to its macroscopic thermodynamic properties. ... -
Frustrated Magnetism and Electronic Properties of Hollandite Oxide Materials
(2017)Microporous transition metal oxides with the hollandite structure type have been prepared by standard solid-state techniques with varying compositions. With a nominal formula of AxM8O16 and a framework of edge and ... -

Functionalization of Surfaces Using Photolithography and Other Techniques
(2011)Coated materials are encountered on a daily basis, and are a part of almost everything manufactured today. Despite their ubiquity, investigations on their chemical functionality and structure still provide interesting ... -
Functionalized 3D DNA Crystals through Core-Shell and Layer-by-Layer Assembly
(2019)A fundamental goal of DNA nanotechnology has been assembly of DNA crystals for use as molecular scaffolds to organize arrays of guest molecules. We use previously described 3D DNA crystals to demonstrate core-shell and ... -
Functionalized Acyclic Cucurbit[n]uril Molecular Containers as Reversal Agents for Drugs
(2017)The study of molecular containers has a prominent place in the scientific literature with many applications, including drug reversal. The clinical use of the cyclodextrin based reversal agent BridionTM has greatly improved ... -
Fundamentals of Excess Electron Transport in Biologically Relevant Systems
(2008-01-25)Thymine dimers are premutagenic lesions that form via ultraviolet irradiation of DNA. While the distribution of thymine dimers is non-random, it is also not yet predictable. Thymine dimer accumulation is likely to be ... -
A GAS-INJECTION NEGATIVE ION SOURCE FOR ACCELERATOR MASS SPECTROMETRY
(2004-11-04)Accelerator mass spectrometry is an ultra-sensitive isotopic analysis technique that allows for the determination of rare long-lived radionuclides such as radiocarbon. Historically, the technique has required that samples ... -
THE GATING OF THE BACTERIAL MECHANOSENSITIVE CHANNEL MSCS REFLECTS ITS FUNCTION AS A SENSOR OF BOTH CROWDING AND LATERAL PRESSURE AS WELL AS ITS ROLE IN OSMOREGULATION
(2014)The mechanosensitive channel MscS is a ubiquitous bacterial membrane valve that opens by increased tension in the event of osmotic down-shock, releasing small internal osmolytes and thus preventing the cell from excessive ... -
