Résumé :
The photo-stimulating discharge (PSD) and ultraviolet-visible spectrometry were used to characterize the polyethylene (PE) and nano-hybrid PE trap before and after ultraviolet aging. In PE with the increasing of ultraviolet aging time, shallow traps reduce gradually and deep traps increase gradually, but for the nano-hybrid PE, shallow traps increase gradually and deep traps reduce gradually. Experiments show that: in the process of aging PE produces oxidation products such as carbonyl, hydroxyl etc. The incorporation of impurities can inhibit the injection of space charges, so as to achieve the purpose of improving electric field distortion in the body of the PE.

Résumé :
We have developed an efficient computational scheme for integration of the classical Hamilton equations describing the ion dynamics confined in the radio-frequency field of the Paul trap. It has permitted a quantitative treatment of cold atom-ion resonant collisions in hybrid atom-ion traps with taking into account unremovable ion micromotion caused by the radio-frequency fields (V.S. Melezhik et. al., Phys. Rev. A100, 063406 (2019)). The important element of the hybrid atom-ion systems is the electromagnetic Paul trap confining the charged ion. The oscillating motion of the confined ion is defined by two frequencies of the Paul trap. It is the frequency of the order of 100 kHz due to the constant electric field and the radio-frequency of about 1-2 MHz defined by the alternating electromagnetic field of the ion trap. The necessity to accurately treat the ion motion in the combined field with two time scales defined by these two very different frequencies has demanded to develop the stable computational scheme for integration of the classical Hamilton equations for the ion motion. Moreover, the scheme must be stable on rather long time-interval of the ion collision with the cold atom ∼ 10 × 2/ defined by the atomic trap frequency ∼ 10 kHz and in the moment of the atom-ion collision when the Hamilton equations are strongly coupled. The developed numerical method takes into account all these features of the problem and makes it possible to integrate the system of coupled quantum-semiclassical equations with the necessary accuracy and quantitatively describes the processes of atomic-ion collisions in hybrid traps, including resonance effects.

Résumé :
In the development of atomic, molecular, and optical (AMO) physics, atom-ion hybrid systems are characterized by the presence of a new tool in the experimental AMO toolbox: atom-ion interactions. One of the main limitations in state-of-the-art atom-ion experiments is represented by the micromotion component of the ions’ dynamics in a Paul trap, as the presence of micromotion in atom-ion collisions results in a heating mechanism that prevents atom-ion mixtures from undergoing a coherent evolution. Here, we report the design and the simulation of a novel ion trapping setup especially conceived of for integration with an ultracold atoms experiment. The ion confinement is realized by using an electro-optical trap based on the combination of an optical and an electrostatic field, so that no micromotion component will be present in the ions’ dynamics. The confining optical field is generated by a deep optical lattice created at the crossing of a bow-tie cavity, while a static electric quadrupole ensures the ions’ confinement in the plane orthogonal to the optical lattice. The setup is also equipped with a Paul trap for cooling the ions produced by photoionization of a hot atomic beam, and the design of the two ion traps facilitates the swapping of the ions from the Paul trap to the electro-optical trap.

Résumé :
Starting from a degenerate Bose gas in a hybrid trap combining a magnetic quadrupole trap and an attractive optical trap resulting from a focused laser beam, we demonstrate the efficient loading of this quantum gas into a shell-shaped trap. The shell trap is purely magnetic and relies on adiabatic potentials for atoms in an inhomogeneous magnetic field dressed by a radiofrequency (rf) field. We show that direct rf evaporation in the hybrid trap enables an efficient and simple preparation of the cold sample, well adapted to the subsequent loading procedure. The transfer into the shell trap is adiabatic and limits the final excitation of the center-of-mass motion to below 2 [Formula: see text]m.

Résumé :
ABSTRACT Pseudomonas putida G7 carries a naphthalene-catabolic and self-transmissible plasmid, NAH7, which belongs to the IncP-9 incompatibility group. Adjacent to the putative origin of conjugative transfer (oriT) of NAH7 are three genes, traD, traE, and traF, whose functions and roles in conjugation were previously unclear. These three genes were transcribed monocistronically and thus were designated the traD operon. Mutation of the three genes in the traD operon resulted in 10- to 105-fold decreases in the transfer frequencies of the plasmids from Pseudomonas to Pseudomonas and Escherichia coli and from E. coli to E. coli. On the other hand, the traD operon was essential for the transfer of NAH7 from E. coli to Pseudomonas strains. These results indicated that the traD operon is a host-range modifier in the conjugative transfer of NAH7. The TraD, TraE, and TraF proteins were localized in the cytoplasm, periplasm, and membrane, respectively, in strain G7 cells. Our use of a bacterial two-hybrid assay system showed that TraE interacted in vivo with other essential components for conjugative transfer, including TraB (coupling protein), TraC (relaxase), and MpfH (a channel subunit in the mating pair formation system).

Résumé :
Abstract Fumed silica-filled polypropylene (PP)-based nanodielectrics were studied in this work. To not only improve the dispersion of the silica but also introduce deep charge traps into the polymeric matrix, five types of modified silicas were manufactured with different surface modifications. The modified silica surfaces comprise an inner and a surface layer. The inner layer contains a polar urethane group for tailoring the charge trap properties of the PP/propylene–ethylene copolymer nanocomposites, whereas the surface layer consists of hydrocarbons (ethyl-, tert-butyl-, cyclopentyl-, phenyl-, or naphthalenyl moieties) in order to gain a good dispersion of the silica in the unpolar polymer blend. Scanning electron microscopic pictures proved that these tailored silicas show a much better dispersion than the unmodified one. Thermally stimulated depolarization current measurements revealed the ability of the silica to introduce deep charge traps with low trap density. The trap depth distribution depends on the type of the unpolar surface layer consisting of the different hydrocarbons. Among these five differently modified silicas, the introduction of the one with a surface layer consisting of tert-butyl moieties resulted in the lowest charge injection and the lowest charge current in the nanocomposite, proving good dielectric performance. Additionally, this silica exhibits good dispersion in the polymeric matrix, indicating a promising performance for nanodielectric application.

Texte intégral
Résumé :
This thesis describes the progress made in trapping and cooling silica nanoscale particles, in a hybrid electro-optical trap. The light field of a high finesse Fabry-Perot cavity and the quadrupole field generated by an rf Paul trap are used for the first time to both trap and cool naturally charged 209 nm dielectric nanospheres in high vacuum. Particles are first loaded into the Paul trap at pressures of 10^-1 mbar, after which their centre-of-mass motion is damped via optomechanical cooling, as the pressure is lowered to 10^-6 mbar. The combined ion trap-optical cavity set-up exposes an interesting interplay between the ion trap dynamics and the cavity mode which lead to a novel optomechanical cooling mechanism of a cyclic nature. This eliminates the need for a second, dedicated cooling mode from the cavity, or feedback cooling in order to cool the levitated particles to the ground state. At the same time, we identify a previously unobserved shift of the Paul trap secular frequencies due to the optical cavity, which enables readout of key parameters, such as the nanoparticles charge and the mean number of photons in the cavity. The dynamical features of the levitated particle, driven by linear and nonlinear optomechanical coupling, are observed through the cavity output, as well as the light scattered by the particle. As the background pressure is lowered, we observe greater than 1000 fold reduction in the centre-of-mass temperature of particles, before temperatures fall below the read-out sensitivity of the set-up.

Christensen, Peter. « Hybrid quadrupole linear ion trap mass spectrometry : application to metabolites ». Thesis, University of Nottingham, 2009. http://eprints.nottingham.ac.uk/13677/.

Texte intégral
Résumé :
The capability of the QqQLit hybrid triple quadrupole linear ion trap mass spectrometer to profile endogenous metabolites has been assessed by the analysis of three different families of metabolites; nucleotides from bacteria and N-acyl ethanolamines and N-acyl glycerols from rat tissues. Mass spectrometry methods were developed based on employing a survey scan, either precursor ion or neutral loss, coupled with full product ion spectra. This approach identified families of metabolites with a common structural core and provided the structural information for the reliable identification of known and unknown metabolites. By targeting structural similarities, this approach has opened the window of metabolites that can be profiled beyond the constraints of available references standards. A method to profile phosphate containing endogenous metabolites, particularly nucleotide metabolites, was based on the identification of the phosphate moiety following collision induced dissociation. Employing a precursor ion scan, this approach was successfully applied to the analysis of nucleotides in bacterial samples Escherichia coli MG 1655 and Pseudomonas aeruginosa. A more comprehensive profile of nucleotides was observed compared to targeted approaches. Furthermore, a considerable number of additional analytes were identified which were unlikely to be nucleotides and probably result from other endogenous phosphate containing metabolites, demonstrating the scope of the approach outside nucleotides alone. The use of this methodology was also successful in the profiling ofN-acyl ethanolamines and N-acyl glycerols. Targeting core structures common to each family of metabolite, the ethanolmine and glycerol moiety, precursor ion and neutral loss survey scans were successfully employed in identifying a wider number of these metabolites in various rat tissues than previously reported. The profile of rat testi was notably different from other tissues investigated due to the presence of MAG and NAB C22:5; analytes not detected in other tissues by this method. Furthermore, as far as it can be ascertained, MAG C22:5 has not been previously reported in rat tissues. A quantitative method based on precursor ion - product ion transitions was developed based on the NABs and MAGs identified by the survey scans. By employing this method to analyze various rat tissues harvested immediately after death and five hours post mortem, quantitative data was obtained not only for a broad range of NABs and MAGs at basal levels but also an insight into postmortem changes of these analytes.

Résumé :
Hybrid trap experiments are set-ups that allow to study the interaction between ions and atoms in cold controlled environment. In such context, molecular anions present specific theoretical and experimental interests and challenges. In this work, we have used extensive \textit{ab initio} methods to investigate several collisional anionic systems: (1) M + OH$^{-}$ (where M are alkali or alkaline earth atoms), (2) Rb and H + OH(H$_{2}$O)$_{n}^{-}$ (with $n=0,1,2,3,4$) and (3) Rb and Li + C$_{2}^{-}$. Several molecular properties such as vertical detachment energies or electroaffinities, optimized structures, harmonic frequencies, potential energy curves or surfaces, etc have been calculated using high level quantum chemistry approaches. The results have been used to make predictions on the related reactivity in low energy regime. We emphasis on electronic detachment processes by carefully analysing the difference between the neutral and anionic potential energy surface. The Rb + OH$^{-}$ system is currently under experimental investigation. Therefore, a detailed study of its reactivity is carried out in the present work. We have analysed the different reactive channels arising from both collision involving the ground state and first electronic excited state of Rb. Using our calculated potentials and a capture model based dynamics, we have extracted cross sections and rate constants. Comparison with other alkali and earth alkaline atoms are made. Hydrated hydroxide cluster anions are planned by the experimental group as upcoming studied systems. We present here our preliminary results on the possible outcome when considering collisions with Rb and we discuss their implications for hybrid trap experiments. We make comparison with H as a colliding partner and consider our results in the context of astrochemistry. Finally we propose the C$_{2}^{-}$ molecular anion as an alternative to OH$^{-}$. Its interaction and reactivity with Rb and Li are investigated and the results are used to motivate our suggestion. Furthermore, for the Rb+OH$^{-}$ and Rb+C$_{2}^{-}$ system, we have also investigated the effect of a non-thermal collision energy distribution on the rate constants. At last, in light of the discussions related to each topic, general conclusions on the use of molecular anions in hybrid trap experiments are drawn.

Résumé :
An LC-MS/MS method was developed and validated to be used as a stability indicating assay for the study of a 3 mg/mL lansoprazole oral suspension. The method utilizes a UPLC (ultra-performance liquid chromatography) column and unique mass spectrometric detection (ion-trap time-of-flight (IT-TOF)) to achieve a sensitive (LOD 2 ng/mL), accurate, and reproducible quantification of lansoprazole. This method reports an intraday and interday coefficient of variation of 2.98 ± 2.17% ( for each concentration for each day) and 3.07 ± 0.89% ( for each concentration), respectively. Calibration curves (5–25 μg/mL) were found to be linear with an value ranging from 0.9972 to 0.9991 on 4 different days. Accuracy of the assay, expressed as % error, ranged from 0.30 to 5.22%. This method is useful for monitoring the stability of lansoprazole in oral suspension.

Résumé :
Diese Arbeit beschäftigt sich mit der theoretischen Beschreibung eines Hybridsystems eines ultrakalten neutralen Atoms und eines einzelnen Ions. Diese Hybrid-Atom-Ion-Systeme verbinden die wichtigsten Vorteile von ultrakalten neutralen Atomen und Ionen. Neutrale Atome sind leicht skalierbar vor allem und können in großen Stückzahlen vorbereitet werden, wahrend gefangene Ionen über längere Zeiten gelagert werden können und leicht kontrollierbar sind. Einige der vorgeschlagenen Aussichten der hybriden Quantensysteme umfassen die sympathische Kühlung von eingefangenen Ionen, die ultrakalte Chemie, das Quantum Informationsverarbeitung, und Atom-Ionen-Quantensimulatoren. Diese Anwendungen erfordern eine äußerst präzise Steuerung und damit eine sehr genaue theoretische Modellierung. Eine neue Methode, die eine vollständige sechsdimensionale Behandlung von zwei Partikeln ermöglicht In räumlich getrennten dreidimensionalen Fangpotentialen wurde entwickelt. Indem man die raumliche Verschiebung zwischen den Einfangpotentialen erlaubt, ist es möglich, die gesteuerte Bewegung eines einzelnen Ions durch ein optisches Gitterpotential zu beschreiben, das mit neutralen Atomen gefüllt ist. Die Wechselwirkung zwischen dem neutralen Atom und dem geladenen Ion wird durch eine realistische Born-Oppenheimer Potentialkurve beschrieben. Eines der hier diskutierten Hybridsysteme ist 7Li2+ Isotop, das mit der neu entwickelten Methode untersucht wird, dabei wurden vermiedene Kreuzungen im Energiespektrum zwischen molekularen Zuständen und den Schwingungszuständen des Fallenpotentials als Funktion des Abstandes zwischen den beide Fallen beobachtet. Diese vermiedenen Kreuzungen bestatigen die bereits vorhergesagten falleninduzierten Resonanzen, die mithilfe der Quantendefekttheorie bestimmt wurden. Ebenfalls werden die erst kürzlich entdeckten inelastischen falleninduzierten Resonanzen in ultrakalten Atomen auch in den Atom-Ion Systemen beobachtet.
This thesis deals with the theoretical description of a hybrid system of an ultracold neutral atom and a single ion. These hybrid atom-ion systems combine the key advantages of ultracold neutral atoms and ions. In particular, neutral atoms are easily scalable and can be prepared in large numbers, while trapped ions can be stored for much longer times and are easy to control. Some of the proposed prospects of the hybrid quantum systems include sympathetic cooling of trapped ions, ultracold chemistry, quantum information processing, and atom-ion quantum simulators. These applications require extremely precise control and thus very accurate theoretical modeling. A new method that allows for a full 6-dimensional treatment of two particles in spatially separated 3-dimensional trapping potentials was developed. By allowing for the spatial displacement between the trapping potentials, it is possible to describe the controlled motion of a single ion through an optical-lattice potential filled with neutral atoms. The interaction between the neutral atom and the ion is modeled using realistic Born-Oppenheimer potential curves from ab initio quantum chemistry calculations. An application of the developed approach to the hybrid atom-ion system reveals avoided crossings between the molecular bound states and the unbound trap states as a function of the separation between the two traps. These avoided crossings correspond to trap-induced resonances. This finding confirms the trap-induced resonances predicted earlier based on quantum-defect-theory calculations. Also, the recently found inelastic confinement-induced resonances in ultracold neutral atoms are demonstrated to be present in atom-ion systems. These resonances arise due to the coupling between the center-of-mass and relative motions. The inelastic confinement-induced resonances could be used in coherent molecular ion formation and in the determination of atom-ion scattering properties like the scattering lengths.

Texte intégral
Résumé :
The cyclic nitrone 5,5-dimethyl-1-pyrroline-N-oxide (DMPO), and the lesser known linear phenyl-N-tert-butylnitrone (PBN) and its phosphorylated analogues have been used as spin traps for the investigation of free radicals in biological systems. Theoretical work on these molecules suggests that there are important differences in their properties between biological systems and isolated molecules in the gas phase, most likely resulting from intra and intermolecular hydrogen bonding. Most dielectric solvation models such as the polarized continuum model and COSMO are incapable of direct determination of solvent-spin trap chemical interactions. To examine this, hybrid models incorporating COSMO for long range effects and discrete solvent molecules for short range effects, at the DFT/B3LYP/6-31G* level of theory, have been used to study the stabilization and alteration of the spin trap molecules properties in protic and aprotic polar solvents. The hybrid models have been successfully implemented to support the prominent role played by hydrogen bonding interactions in the stabilization of spin traps.

Résumé :
In or, on being the other woman, Simone White considers the dynamics of contemporary black feminist life. Throughout this book-length poem, White writes through a hybrid of poetry, essay, personal narrative, and critical theory, attesting to the narrative complexities of writing and living as a black woman and artist. She considers black social life—from art and motherhood to trap music and love—as unspeakably troubling and reflects on the degree to which it strands and punishes black women. She also explores what constitutes sexual freedom and the rewards and dangers that come with it. White meditates on trap music and the ways artists such as Future and Meek Mill and the sonic waves of the drum machine convey desire and the black experience. Charting the pressures of ordinary black womanhood, White pushes the limits of language, showing how those limits can be the basis for new modes of expression.

Résumé :
Abstract Using the example of the Alps, it was shown that hybridity in tourism touches primarily three marketing fields: (a) Product. Because of attractions that change their character and level of appeal throughout the year or are linked to yearly events and habits, the perception of the core elements of the destination's image varies; (b) Communication. The hybridity of the product implies the need to address different target groups, as the changing focus of the destination image attracts different, often disjunctive or mutually exclusive, consumer groups; and (c) Pricing. Similar to all fields of consumption, an increasing polarization between low cost or bargain trips and high priced luxury travelling can be found. Some travellers prefer either lowcost or luxury travelling, while others change their expenditure from trip to trip.

Résumé :
A mathematical model and numerical techniques are proposed to study AC electric field induced cellular assembly in a microfluidic device. In the mathematical model, the Maxwell stress tensor is used to calculate the dielectrophoretic force acting on particles by considering the physical effect of particles in the computational domain. Thus, the proposed model eliminates the approximations used in point dipole methods for calculating dielectrophoretic force. The numerical method is based on hybrid immersed boundary-immersed interface methods. An immersed boundary method is used for the fluid equations and particle transport, while an immersed interface method is employed to obtain the AC electric field in a fluid media with suspended particles. For the immersed interface method, an iterative algorithm is developed to solve the complex Poisson equation using a real variable formulation. The decoupled algorithm for solving complex differential equations converges rapidly. The hybrid method is used to investigate the physics of AC dielectrophoresis in a cross-channel junction. The numerical results show that with proper design and appropriate selection of applied potential and frequency, global electric field minima can be obtained to facilitate multiple particle trapping by exploiting the mechanism of negative dielectrophoresis.

Résumé :
In November 2022, Wejo Data Services Inc. provided Purdue with a national data set comprised of approximately 470 billion connected vehicle records covering all 50 states for the month of August 2022. The goal of the evaluation data set was to create a series of summary graphics to evaluate the scalability of work zone analytics graphics and electric/hybrid vehicle counts at a national level. This report illustrates several performance measures developed using this dataset for all interstate routes, both state wise and cross-country. State wise graphics are organized with 50 subdirectories containing graphics for each interstate in the 50 states. There are also a series of multi-state graphics for I-5, I-10, I-15, I-35, I-55, I-65, I-75, I-80, I-90, and I-95. Performance measures include absolute and normalized trip counts classified by type of trip (electric vehicle or hybrid vehicle or internal combustion engine vehicle), weekly heatmaps based on vehicle speed overlaid with hard-braking events and finally, speed profiles by interstate mile markers. Additional details on the directories and how to interpret these performance measures can found inside the document (after extracting the .zip file) titled “National_Mobility_Analysis_README.pdf”.

Résumé :
In January 2023, Wejo Data Services Inc. provided Purdue with a national data set comprised of approximately 503 billion connected vehicle records covering all 50 states for the month of December 2022. The goal of the evaluation data set was to create a series of summary graphics to evaluate the scalability of work zone/winter weather analytics graphics and electric/hybrid vehicle counts at a national level as well as visualize the mobility impacts of winter weather activity on the national interstate network. This report illustrates several performance measures developed using this dataset for all interstate routes, both state wise and cross-country. Statewide graphics are presented for each interstate in the 50 states. There are also a series of multi-state graphics for I-5, I-10, I-15, I-35, I-55, I-65, I-75, I-80, I-90, and I-95 and selected other routes that witnessed winter storm impacts. Performance measures include absolute and normalized trip counts classified by type of trip (electric vehicle or hybrid vehicle or internal combustion engine vehicle), weekly heatmaps based on vehicle speed (for the two-week period from December 12-25, 2022) and finally, speed profiles by interstate mile markers. Traffic tickers depicting miles of congestion as well as mile-hours of congestion for the national interstate network and selected multi-state routes are also included to provide a unified visual of nationwide mobility impact of recurring congestion as well as non-recurring congestion caused by winter weather. The generated performance measures can be found in the supplemental files.
