Streszczenie:

Kidney or gall-bladder stones are solid accretions (crystals) of dissolved minerals in urine or bile juice found inside the kidneys or urethras and gall bladder, with varying size from as small as a grain of sand to as large as a golf ball, the occurrence whose in the human is well known, although its pathogenesis is not well understood. According to literature, a number of biomaterials, such as collagen, blood vessel walls, DNA, RNA etc., are found to possess the property of electrets which is an electric analogue of a permanent magnet having the capability to retain quasipermanently, an induced polarization. In order to understand about the occurrence and the physical properties of stone formation in the human tissues, the study of its electret behaviour and conductivity becomes imperative which implies the fact of indulging in its growth inhibition, if their deposition is identified using scans. Thus, in this paper, in order to understand the mechanism of growth of these nephrolithiasis, we enumerated the electrical behaviour of the stone, by using the XRD (X-Ray Diffraction) analysis after their collection from different patient in and around the region and subsequently the dielectric constant of the stone was interpreted.

Streszczenie:

Polyethylene terephthalate (PET) is one of the major electret materials which has been studied and widely used in charge storage applications for a long time. The homo-charge and hetero-charge formation responsible for the electret effect of PET can be explained by the dipolar polarization, space charge separation and charge injection respectively as a result of contact poling or corona charging. These processes are also verifiable from studies of surface charges and thermally stimulated depolarization current (TSDC) of the PET films. Now consider a stack of PET films charged under the same condition as a single film. It would be intuitively expected that the electret effects of the individual films of the stack should be different due to their different positions in the stack. However, in a recent study on charged PET stacks, it was found that the electret effects of the individual films are quite similar. The surface charges of the individual films are about the same and they sum to make same total as a single charged PET film. On the other hand, the TSDC thermograms of individual films show similar characteristics in the thermal relaxation processes where homo- and hetero- charge effects are still observed. From the TSDC results, especially for the film in the middle of a triple layer sandwich, it shows clearly dipolar polarization and charge injection related peaks. These findings agree with the results of surface charge studies of the individual films.

Streszczenie:

Air filters produced with charged, or electret, media for HVAC filtration applications have gained significant market share and acceptance over the past few years. While these filters provide the advantage of high initial efficiency and low pressure drop, there are concerns about their ability to maintain efficiency in service. Furthermore, there is a tendency to classify all electret media in the same general category without any consideration of media structure, fiber size, and charging technique. Current research suggests that a variety of factors influence the loss of efficiency in use including humidity, exposure to certain chemicals, aging, temperature, and etc. While this is true of some charged media, the effect of environmental factors on filtration performance is highly dependent upon the media technology itself. This paper provides an overview of current electret media types detailing media structure and charging techniques. Fundamental impact of environmental factors on filtration performance is presented along with field studies detailing in-use performance of filterers manufactured with charged media.

Abstract The capabilities of electret ion chambers (EICs) to measure mean ambient dose equivalent rates were investigated by performing both laboratory and field studies of their properties. First, EICs were ‘calibrated’ to measure ambient gamma dose equivalent in the Ionizing Calibration Laboratory of the Greek Atomic Energy Commission. The EICs were irradiated with different gamma photon energies and from different angles. Calibration factors were deduced (electret’s voltage drop due to irradiation in terms of ambient dose equivalent). In the field studies, EICs were installed at eight locations belonging to the Greek Early Warning System Network (which is based on Reuter-Stokes ionization chambers) for three periods, averaging 5 months each. In the same locations, in situ gamma spectrometry measurements were performed with portable germanium detectors. Gamma ambient dose equivalent rates were deduced by the in situ gamma spectrometry measurements and by soil sample analysis. The mean daily electret potential drop (in Volts) was compared with the mean daily ambient dose equivalent, measured with a portable HPGe detector and Reuter-Stokes high-pressure ionization chambers. From these measurements, ‘field’ calibration factors (electret’s voltage drop due to gamma radiation in terms of ambient dose equivalent) were deduced and found in very good agreement with the values deduced in Laboratory. The influence of cosmic radiation and the intrinsic voltage loss when performing long-term environmental gamma measurements with EICs, was estimated.

Streszczenie:

The interaction of low energy electrons with stable and unstable molecules has been investigated with particular emphasis on negative ions formed in dissociative electron attachment. The experiment includes a trochoidal electron monochromator and a time-of-flight mass spectrometer. Measurements of dissociative electron attachment to HCCCN have been made inspired by the presence of this molecule in many extraterrestrial environments and by recent theoretical calculations of electron attachment to HCCCN. Two regions of electron attachment were observed with formation of CCCN- at 1.56 eV and CCCN-, CN-, HCC- and CC at - 5.30 eV where 2 II shape resonances were predicted to be located. Quantum chemical calculations performed in this work confirm these dissociation processes follow electron attachment into empty rr* orbitals. Negative ions were also observed at higher energies due to core excited resonances. Metastable dissociation of SF6-* has been observed in competition with autodetachment after attachment of close to 0 eV electrons to SF6. The lifetime of SF6-* has been estimated from the present measurements as a function of electron energy and hence, the internal energy of the anion. Metastable dissociation of a number of substituted benzene rings, such as dinitrobenzene, has also been investigated. This appears to be the first experimental study of the metastable decay of molecular anions with known internal energies. Measurements of dissociative electron attachment to the unstable CS and molecules have been performed to obtain total cross sections for dissociative electron attachment and characteristic negative ion mass spectra 'fingerprints'. CS forms S- at 5.43 eV, Cat - 6.40 eV and S- at - 6.70 eV. Dissociative electron attachment to CF2 was not observed, and an upper limit of the absolute cross section for the formation of F+CF has been deduced. A potential application of dissociative electron attachment measurements to plasma diagnostics is considered.

This thesis presents the results of experimental investigations to determine the electron ionization cross-sections of gases used in plasma etching processes. The small molecules studied include boron trichloride (BCI3), nitrous oxide (N20), sulphur hexafluoride (SF6) and acetylene (C2H2). The knowledge of accurate electron ionization cross-sections is essential for the modelling and optimization of plasmas used in industry and for the purposes of atmospheric modelling. It is therefore surprising that despite the widespread industrial use of these small molecules there have been few investigations of their ionization. It is the lack of available electron ionization cross-section data that provides the motivation for the investigations detailed in this thesis. The formation and dissociation of singly charged (monocations), doubly charged (dications) and triply charged molecular ions (trications) are studied using pulsed electron ionization (30-200 eV) coupled with time-of-flight (TOF) mass spectrometry and a two-dimensional (2D) ion coincidence technique. The experimental technique and data analysis procedures adopted allow the contribution to the total ion yield from single and multiple ionization to be distinguished and quantified. Such information yields relative partial ionization cross-sections (PICSs) and also allows relative precursor specific PICSs to be determined, which quantify the contribution from single, double and triple ionization to the relative yields of the fragment ions formed following electron-molecule collisions. Relative precursor specific PICSs therefore provide a more 'in-depth' chemical picture of each PICS. The relative precursor specific PICSs determined, following electron interaction with N20, provide clear evidence of energetic ion loss in previous cross-section determinations detailed in the literature. In addition, the 2D ion coincidence technique provides information on the energetics involved in the dissociation of any multiply charged ions formed. In the case of BCI3, further insight on the possible dissociation dynamics of BC132+ is reported. Following the investigations of N2O, BCI3 and SF6, the apparatus was commissioned to produce absolute partial ionization cross-sections and absolute precursor specific partial ionization cross-sections from 30-200 eV. Experimentally, the commissioning involved the addition of a Spinning Rotor Gauge (SRG) and a new gas inlet line to the source region. These investigations have extended the data determined for the electron ionization of N20 and have also enabled the absolute cross-section data for the electron ionization of C2H2 to be determined.

Streszczenie:

The goal of solid state physics and chemistry is to gain deeper understanding of the basic principles of condensed matter. This ongoing process is achieved by the combination of experimental methods and theoretical models. One theoretical approach are the so-called first-principles calculations, which are based on the concept of density functional theory (DFT). In order to test the reliability of a band structure calculation, its results have to be compared with experiments. Since the electron density, the main constituent of DFT codes, cannot be directly determined experimentally with sufficient accuracy (e.g., by X-ray diffraction), other experimentally available properties are needed for the comparison with the calculation. A quantity that can be measured with high accuracy and that provides indirect information about the electron density is the electric field gradient (EFG). The EFG reflects local structural symmetry properties of the charge distribution surrounding a nucleus: the EFG is nonzero if the density deviates from cubic symmetry and therefore generates an inhomogeneous electric field at the nucleus. Since the EFG is highly sensitive to structural parameters and to disorder, it is a valuable tool to extract structural information. Furthermore, the evaluation of the EFG can provide valuable insight into the chemical bonding. Whereas the experimental determination of the quadrupole frequency and the closely related EFG has been possible for more than 70 years, reliable values for calculated EFGs could not be obtained before 1985, when an EFG module was implemented in the full-potential, linearised-augmented-plane-wave code WIEN. Since the full-potential local-orbital minimum-basis scheme FPLO is numerically very efficient and its local-orbital scheme allows an easy analysis of the different contributions to the EFG, one goal of this work was the implementation of an EFG module within the FPLO code. The newly implemented EFG module was applied to different systems: starting from simple metals, then approaching more complex systems and finally tackling strongly correlated oxides. Simultaneously, the EFGs for the studied compounds were determined experimentally by NMR spectroscopists. This close collaboration enables the comparison of the calculated EFGs with the experimental observations, which makes it possible to extract more physical and chemical information from the measured values regarding structural relaxation, distortion, the chemical bond or the relevance of electron correlation. In the last part of this work, the importance of corrections that go beyond the EFG are discussed. Such corrections arise for any multipole order of the hyperfine interactions, and are due to electron penetration into the nucleus. A correction similar to the isomer shift, coined here the "quadrupole shift" is examined in detail.

Streszczenie:

The electron-electron coincidence (e,2e) technique yields complete kinematical information about the electron impact ionization process. The (e,2e) technique has been widely used to study dynamical effects in ionizing collisions with atomic targets, however studies of molecular ionization using this technique have been very limited. Recently further experimental studies of small molecules have been proposed, as the cross sections of small molecules are now computable using sophisticated theoretical approaches [77, 24]. This thesis presents dynamical investigations for the electron impact ionization of the molecular targets H2O and H2, employing the (e,2e) technique to experimentally measure the triple differential cross section (TDCS). The TDCS is defined as the probability that a bound electron will be ejected from the target atom or molecule (into a particular direction with a defined energy) and the initial electron will be scattered into a particular direction with a particular energy. All TDCSs presented within this thesis were performed using an electron coincidence spectrometer in the coplanar asymmetric geometry at intermediate incident electron energies. This thesis presents the electron impact ionization TDCSs of H2O. A series of measurements were performed using H2O in the vapour form. Measurements of the TDCS are presented for the 2a1 atomic-like orbital and the 1b2, 3a1 and 1b1 molecular orbitals at a common incident electron energy of 250eV, ejected electron energy of 10eV and scattering angle of -15o. The experimental TDCSs are compared with theoretical cross sections that were calculated by Champion et al [25, 26] using a distorted wave Born approach (DWBA). TDCS measurements for the single ionization of the hydrogen molecule, H2 were performed as in recent years there has been evidence that indicates the ejected electron angular distribution is perturbed due to Young-type interference effects. The oscillatory structure which is predicted in the cross section is due to the two-centred nature of the molecule [27, 29]. This thesis presents experimental TDCSs for the ionization of H2 which are compared to TDCSs of helium. A series of measurements for the TDCSs of H2 and He are presented at a common incident electron energy of 250eV and scattering angle of -15o, for a range of ejected electron energies between 10eV and 100eV. The experimental TDCSs are compared with two types of theoretical calculations.

Streszczenie:

Rational magnetic flux surfaces in fusion (toroidal plasma confinement) devices can break the magnetic field lines and reconnect them in the form of magnetic islands. Formation of these magnetic islands can have a serious impact on the plasma confinement properties of the device. Islands can in general degrade the confinement by mixing up different regions of the plasma. However there has been experimental evidence of confinement improvement by island induced transport barriers, under certain conditions. Even though there are a large number of theoretical and experimental works on magnetic islands to date, there is clearly a paucity of convincing experimental understanding on the nature of behaviour of islands in plasma. This thesis reports detailed experimental studies conducted on the H-1NF heliac stellarator, to gain an in-depth understanding of magnetic islands and their influence in plasma confinement.¶ Work reported in this thesis can be mainly divided into three parts: (a) high resolution imaging of vacuum magnetic islands and flux surfaces of H-1NF, (b) accurate computer modeling of H-1NF magnetic geometry and (c) detailed experiments on magnetic islands in plasma configurations.¶ Electron-beam wire-tomography in the H-1NF has been used for the high resolution mapping of vacuum magnetic flux surfaces and islands. Point-to-point comparison of the mapping results with computer tracing, in conjunction with an image warping technique, has enabled systematic exploration of magnetic islands and surfaces of interest. A fast mapping technique has been developed, which significantly reduced the mapping time and made this technique suitable for mapping at higher magnetic fields.¶ Flux surface mapping has been carried out at various magnetic configurations and field strengths. The extreme accuracy of this technique has been exploited to understand the nature of error fields, by point-by-point matching with computer tracing results. This has helped in developing a best-fit computer model for H-1NF magnetic configurations, which can predict rotational transform correct to three decimal places. Results from plasma experiments on magnetic configuration studies are best explained by the new model.¶ Experiments with low order magnetic islands in plasma configurations yielded some new results. It has been observed that the low order magnetic islands (m = 2) near the core of the plasma serve as pockets of improved confinement region under favourable conditions. This results in significant profile modifications including enhancement of the radial electric field near the core to a large positive value. The characteristics of islands are found to be dependent on the plasma collisionality and the island width.¶ Experiments with a magnetic configuration which exhibits no vacuum islands, but the core rotational transform very close to low order rational value, show a spontaneous transition of the radial electric field near the core to a large positive value (nearly 5 kV/m), with a strong electric field shear (nearly 700 kV/m2) and localised improvement in confinement, during the discharge. Evidence indicates that the transition is driven by the excitation of low order magnetic islands near the axis during the plasma discharge, due to the modification of rotational transform profile by toroidal plasma currents. The situation is similar to the Core Electron-Root Confinement (CERC) observed during high temperature ECH plasma discharges on other helical devices. This result provides an experimental evidence for the hypothesis that the threshold conditions for observing CERC can be reduced by exciting magnetic islands near the core of the plasma.

Streszczenie:

Advances in electric propulsion may provide the opportunity to incorporate multiple distributed propulsors through the use of electric drives and electric power transmission at dramatically lighter weights than mechanical drivetrains. While small-scale UAS (0-20lb) have achieved distributed electric drivetrains, the electro-chemical power-sources do not scale and are weight prohibitive for larger UAS and future eVTOL aircraft with practical range, endurance, and payload requirements. An alternative to the electro-chemical powertrain is the hybrid-electric powertrain. In this paper, a variable-voltage hybrid-electric powertrain is designed, constructed, and tested carefully to examine the effects of variable-voltage generators for variable-RPM electric drives. The paper examines the powertrain component by component, with over 370 test points, from a single electric drive to an integrated powertrain with four distributed propulsors, in a fully instrumented test bed.

Streszczenie:

The paper presents the initial results on the performance of cellulose-based Electro-Active Papers (EAPap) as actuators. The electro-active papers depend on ion migration and dipole moment for the actuation. EAPap is fabricated by depositing gold electrodes on the top and bottom surfaces of cellophane sheets. Small sheet specimens measuring approximately 1 cm × 3 cm, suspended from the 1 cm width were tested in this study. The characteristics of EAPap are evaluated by applying electric fields at different exciting frequencies and humidity levels. The dynamic responses of the specimens were measured using a scanning Laser vibrometer. As expected, different plate modes are excited at different frequencies. Wide variations in the performance of the specimens were seen bat different levels of humidity. The results indicate the potential of EAPap for low power and lightweight actuation.

Streszczenie:

The analysis of the electron acceleration by the quasi-stationary sub-Dreiser electric ﬁelds in the lower solar atmospherehas been done. It has been shown that the Dreiser electric ﬁeld turned out to be several orders of magnitude larger thancoronal values due to the inelastic collisions between electrons and hydrogen atoms. The ionization of hydrogen atoms givesrise to the resulting secondary electrons, which become runaway under the action of sub-Dreiser electric ﬁelds. This causesan further avalanche-like ionization of the plasma and leads to the acceleration of the large number of fast electrons up torelativistic energies at small (. 100 km) distances.

Streszczenie:

The steady state airflow and electric field distributions in a corona device (corotron) during charging of a moving dielectric substrate (photoreceptor) for different operating conditions are studied. The set of two-way, fully-coupled electro-hydrodynamics governing equations is used in the analysis and parametric studies are performed. The effects of wire voltage, photoreceptor speed on photoreceptor charging, airflow, charge density and electrical potential are studied. It is shown that the charging is strongly affected by the wire voltage and the substrate speed. The results also show the importance of corona effect on the flow structure in the device.

Streszczenie:

The linear electro-optic (EO) effect, in conjunction with second harmonic generation (SHG) has been used to study temperature and electric field effects on dye-doped guest-host systems. An interferometric technique with in-situ poling was used to probe the poling field- induced molecular alignment of the chromophores as a function of temperature. The doped polymer systems were thin films of 4-dimethylamino-4'-nitrostilbene or disperse red 1 chromophores doped into poly(methyl methacrylate). For small poling fields, this technique revealed the linear dependency of the electro-optic-coefficient, r, and thus the second order susceptibility χ(2) of the material, on low poling fields. It was also possible to detect the β-relaxation, the secondary transition occurring below the glass transition temperature, which until now has not easily been seen in studies using optical techniques.

Streszczenie:

Second harmonic generation at surfaces (SSHG) has recently been the subject of increasing interest among researchers who require a probe of interfacial phenomena that is both surface-specific and can be utilized in condensed phase studies (see [1] and references therein). SSHG belongs to a larger class of second order nonlinear optical processes that includes optical rectification, sum and difference frequency mixing, and the Pockles effect, all of which are symmetry forbidden in isotropic media (at least in the electric dipole approximation [1]). At an interface between dissimilar media the isotropy which may be present in the bulk material is disturbed, and processes such as second harmonic generation can occur. This property is attractive for probing surface phenomena because only very weak electric quadrupole and magnetic dipole signals are generated in the bulk material. Furthermore, SSHG is an optical effect and requires only transparency of the media at the fundamental and harmonic wavelength, rather than the more stringent condition of ultrahigh vacuum imposed by electron and ion probes.
