State-Resolved Reaction Dynamics ( Book )
4 editions published between 1985 and 1998 in English and held by 4 WorldCat member libraries worldwide
This research effort is comprised of two groups of experiments. The first group measures and characterizes the electron ejected in a photoionization event. The second group is concerned with understanding the role of energy in affecting the outcome of ion-molecule reactions. High resolution, angle-resolved photoelectron spectroscopy was carried out following resonance enhanced multiphoton ionization (REMPI) of nitric oxide. These measurements have led to a complete description of this photoionization event. Photoelectron spectroscopy was also used to measure the degree of vibrational state-selectivity resulting from REMPI of NH3 and HBr/DBr. Additionally, the rotational state distributions resulting from HBr/DBr/HCl REMPI were measured using LIF. These state distributions were used in the study of the near resonant charge transfer reaction of DBr+ + HBr, where the reagent ion was state-selectively prepared with REMPI and the product state distributions were monitored with LIF. Vibrationally state-selected ammonia ions generated by REMPI were used to investigate the effect of kinetic and vibrational energy in determining the product formation tendencies of the reaction NH 3++ ND3. Measurement of the product cross sections has shown the differing effects of vibrational and translational excitation on dynamics of this ion-molecule system

Fluorophores for single-molecule imaging in living cells characterizing and optimizing DCDHF photophysics by Samuel Joseph Lord( )
1 edition published in 2010 in English and held by 2 WorldCat member libraries worldwide
The number of reports per year on single-molecule imaging experiments has grown roughly exponentially since the first successful efforts to optically detect a single molecule were completed over two decades ago. Single-molecule spectroscopy has developed into a field that includes a wealth of experiments at room temperature and inside living cells. The fast growth of single-molecule biophysics has resulted from its benefits in probing heterogeneous populations, one molecule at a time, as well as from advances in microscopes and detectors. There is a need for new fluorophores that can be used for single-molecule imaging in biological media, because imaging in cells and in organisms require emitters that are bright and photostable, red-shifted to avoid pumping cellular autofluorescence, and chemically and photophysically tunable. To this end, we have designed and characterized fluorescent probes based on a class of nonlinear-optical chromophores termed DCDHFs. This Dissertation describes various physical and optical studies on these emitters, from sensing local environment to photoactivation. Chapter 1 is a general introduction to fluorescence and single-molecule spectroscopy and imaging. Single-molecule experiments in living cells are discussed and probes used for such experiments are summarized and compared. Chapter 2 explores the basic photophysics of the DCDHF fluorophores and some general methods of measuring relevant spectroscopic parameters, including photostability. Chapter 3 discusses the various approaches we have taken to modify particular properties by changing the fluorophore's structure. We have redesigned the DCDHF fluorophore into a photoactivatable fluorogen--a chromophore that is nonfluorescent until converted to a fluorescent form using light--described in Chapter 4. Finally, a different, chemical route to fluorescence activation is presented in Chapter 5. The remainder of the Dissertation is the Appendix and a full Bibliography. The Appendix includes a table of photophysical parameter for DCDHF fluorophore, various protocols used in the experiments discussed, MatLab codes, and NMR spectra
Single-walled carbon nanotubes (SWNTs) as near infrared fluorescent imaging agents in biological systems by Kevin David Welsher( )
1 edition published in 2010 in English and held by 2 WorldCat member libraries worldwide
The near infrared range has long been known to be advantageous for biological imaging and sensing applications. In particular, the second near infrared window (1000 nm -- 1400 nm, NIR II) is characterized by low endogenous autofluorescence and deep tissue penetration due to reduced tissue scatter. To address the dearth of fluorophores in this window, this work focuses on utilizing the intrinsic near infrared photoluminescence of semiconducting single walled carbon nanotubes (SWNTs) to take advantage of this unique spectral region. First, SWNTs are made bio-inert and applied as fluorescent probes for highly specific cellular targeting using antibodies such as Rituxan and Herceptin. These probes were then used for the first whole animal fluorescent imaging using SWNTs in vivo following tail vein injection, including the observation of high SWNT accumulation in tumors. By implementing a surfactant exchange method to improve the fluorescence yield of SWNTs solubilized by phospholipid-polyethylene glycol, high magnification intravital microscopy of tumor vessels beneath thick skin was achieved. Further improvements were made to improve the fluorescence yield of the SWNT probes by utilizing a density gradient separation method which removed poorly fluorescent short tubes and nanotube bundles. Another separation method, ion-exchange chromatography was applied to isolate single chirality SWNTs and perform multicolor NIR imaging in vitro and in vivo. Finally, these bright, biocompatible nanotube fluorophores were used to achieve video rate imaging of mice in vivo during tail vein injection for dynamic contrast enhanced imaging through principal component analysis. The emission in the NIR II region allowed crisp anatomical resolution, confirmed by mock tissue phantom studies and Monte Carlo simulation

Development of a Miniaturized Hadamard Transform Time-of-Flight Mass Spectrometer ( )
1 edition published in 2007 in English and held by 1 WorldCat member library worldwide
This report details advances in theory and technology for the precise deflection of high kinetic energy ion beams using Bradbury-Nielsen gates (BNGs) and their application to high duty cycle miniaturized mass spectrometry. We have developed methods to fabricate BNGs using template assisted manual weaving and silicon-on-insulator microfabrication. These devices have been characterized using ion beam imaging techniques, and the results compared to mathematical models of the deflection process developed for this purpose. A new vacuum-compatible electronic system has been constructed to allow the deflection of ions using BNGs following an arbitrary digital sequence that minimizes the impact of impedance mismatching within the circuit and improves the precision of deflection. The aforementioned advances have been integrated to develop a new form of time-of-flight mass spectrometry that allows for 100% duty cycle detection of a continuous ion beam. Experiments detailing 100% duty cycle operation are described. The statistical advantages to this form of detection over other forms of mass spectrometry in a shot noise dominant environment are presented
Ultrafast studies of ionic liquids and the role of nanostructural organization by Kendall Stanley Fruchey( )
1 edition published in 2011 in English and held by 1 WorldCat member library worldwide
Ionic liquids are a quickly emerging class of neoteric solvents composed of organic and inorganic ions that remain liquid at room temperature. Their properties are diverse and often unique, bridging the continuum between polar and nonpolar, molecular and ionic. One property which has garnered special attention is the possibly ubiquitous existence of ordering in the bulk liquid, known as nanostructural organization. Resulting from the energetics of balancing the strong electrostatics of ions with steric considerations, it has been suggested that ionic liquids with sufficiently large alkyl substitutions should form distinct regions of polar and non-polar groups within the bulk solvent structure. The characteristics of this ordering, and even its very existence, have been heavily debated topics in ionic liquid research. Two ultrafast fluorescence experiments are discussed which attempt to assess the extent and role of nanostructural organization in the solvent properties of prototypical ionic liquids. Additionally, an Optical Kerr Effect study is described with the aim of understanding the role of Li in ionic liquid electrolytes. Time dependent fluorescence depolarization measurements studied the rotational friction experienced by small charged and nonpolar dye molecules in a series of ionic liquids with increasing alkyl chain lengths. Two distinct behaviors were observed. For a charged pyranine-derivative dye, strong interaction between the dye molecules and ionic liquid leads to a greater rotational friction than the Debye-Stokes-Einstein hydrodynamic theory predicts. The magnitude of this increase scales with the size of the ionic liquid cation. For the nonpolar dye perylene, the rotational friction was less than the slip boundary condition of hydrodynamic theory. Moreover, increasing alkyl chain length causes the rotational behavior to converge on that experienced by the dye in a purely alkane environment. The causes of these trends are discussed, leading to the conclusion that different regions of the nanostructured environment are being assessed. The nonpolar dye is segregated into the nonpolar region of the ionic liquid, so that the rotation friction describes the structure of this region. The charged dye is interacting with the ions in the hydrophilic region. The results shed light on some aspects of nanostructural organization as it applies to ionic liquids as solvents. To assess the spatial characteristics of nanostructural organization, donor-donor excitation transfer was examined. The time dependence of the excitation transfer is strongly sensitive to the distribution of donors and acceptors in solution. Using a dye molecule that is anticipated to segregate into the nonpolar regions, the altered distribution of dye molecules resulting from nanostructural organization will be evident in the excitation transfer. Fluorescence depolarization can be used to monitor the excitation transfer. Observables for an isotropic and structured distribution of dye were calculated, and compared to fluorescence experiments. Based on the fits, an upper bound on the radius of 6-8Å is placed on the size of the hydrophobic regions of nanostructural orgaization, modeled as spheres. The transport properties of ionic liquids as electrolytes are strongly and negatively affected by the addition of lithium. To understand this, Optical Heterodyne Detected Optical Kerr Effect studies were performed on a pure and lithium loaded imidazolium ionic liquid. Mode-coupling theory was tested in the pure liquid, and found to be capable of describing the dynamics. Mode-coupling theory was then used to understand the results in the lithium loaded samples. Changes in parameters from the mode-coupling theory fits occur at a lithium mole fraction of 0.2. This is discussed in terms of outside MD simulations to understand and substantiate the changes in ionic liquid structure leading to the loss of ion mobility
