Resumen
Polyimide is an emerging and very interesting material for substrate and passivation of neural probes. However, the standard curing temperature of polyimide (350 °C) is critical for the microelectrodes and contact pads of the neural probe, due to the thermal oxidation of the metals during the passivation process of the neural probe. Here, the fabrication process of a flexible neural probe, enhanced with a photosensitive and low-temperature cured polyimide, is presented. Annealing tests were performed with metallic films deposited on polyimide, which led to the reduction of the curing temperature to 250 °C, with no significant irregularities in the metallic sample annealed at that temperature and an effective polyimide curing. The use of a lower curing temperature reduces the thermal oxidation of the metals during the polyimide curing process to passivate the neural probe. Additionally, in this fabrication process, the microelectrodes of the neural probe were coated with electrodeposited platinum (Pt), only after the passivation process, and its electrochemical performance was accessed. At 1 kHz, the impedance of the microelectrodes before Pt electrodeposition was approximately 1.2 MΩ, and after Pt electrodeposition, it was approximately 350 kΩ. Pt electrodeposition changed the equivalent circuit of the microelectrodes and reduced their impedance, which will be crucial for future in-vivo tests to acquire the electrical activity of the neurons with the fabricated neural probe.

Resumen
Carbon nanotube (CNT) probe used in atomic force microscopy (AFM) was fabricated by using electron beam induced Pt deposition method. The bonding force for CNT probe was found to be larger than 500nN. The nanotube probe’s length was shortened by focused ion beam milling process. It is confirmed that the CNT probe shows higher aspect ratio than the Si probe. The nanotube probes with fullerene-like cap end present higher imaging resolution than those with open end.

Resumen
To improve the spatial resolutions of scanning electrochemical microscopy (SECM) imaging, the laser-pulled submicron electrode fabrication method was explored in this work. Manual polishing of a laser-pulled Pt nanoelectrode exposed a Pt tip diameter of 250 nm with a ratio of the tip glass to exposed Pt disc (RG) of 30. This fabricated submicron probe was then utilized to study the electrochemical functionality of an independently addressable microband electrodes (IAME) sample using SECM. In the constant imaging mode of SECM, where the probe is scanned linearly across the sample at a fixed z position, SECM demonstrated higher resolution than that of the conventional micrometer electrodes when the feedback currents from the Pt and glass microbands were characterized. In addition, the depth scan imaging mode of SECM was also used to extract experimental horizontal line scans and probe approach curves for analysis. Three-dimensional (3D) simulations of the IAME–SECM probe experiments were explored for the first time to quantify the tip-to-sample distances, tilt angle of the sample (or electrode), and height of the Pt microbands. The experimentally characterized height was found to be similar to manufacturer specification (125 nm vs 110 nm). Furthermore, the more computationally demanding 3D simulation of the true IAME sample geometry (110 nm height of the Pt microbands) revealed minimal difference in feedback behaviours in comparison with the idealized flat geometry. The removal of this simulation complexity was proved to be sufficient for SECM analysis of the IAME sample by a 250 nm Pt probe, which greatly saves computation resources.

Resumen
More than eighty years after the death of its author, Kafka fiction continues to stimulate diverse critical interest: only Shakespeare has generated more publications, more biographies or indeed more PhD theses. In recent years, scholarship has recognised the irreducible, polysemantic nature of Kafka’s writing as a stimulus for this regenerative criticism. Another factor is the author himself, along with his well-known biography. Particularly in published monographs, Franz Kafka’s life story has attracted almost as much attention as the fiction he produced. Thus, unusually for a writer whose works have been so thoroughly dissected by criticism, Franz Kafka seems to have survived the so-called death of the author, promulgated throughout literary theory. This thesis highlights a tension between these two stimuli; between the elusive multivocality of Kafka’s fiction and the ongoing influence of the author. It argues that mythologies about Kafka have now outlived their usefulness, and suggests that greater attentiveness to theoretical insights might benefit the field. Accordingly, this study proposes new ways of looking at Kafka which marginalise the influence of the author and related approaches to his fiction. In its investigation of authority as a theme of Kafka’s writing, this volume repositions Kafka’s fictional and non-fictional output within new and established contexts, exploring philosophical and critical dimensions of the oeuvre. In so doing, it asks what Kafka can teach us about our reading of Kafka, our reading of theory and reading in general.

Resumen
Cette thèse porte sur l'étude d'écoulements alternés au sein de canaux de dimensions milli- et sub-millimétriques. Ces travaux visent à contribuer à l'optimisation d'une machine miniature (dimensions sub-millimétriques) de récupération et de conversion d'énergie basse température (T < 200 °C) basée sur le principe du cycle de Stirling. Ceci s'inscrit dans le contexte de valorisation de la chaleur fatale encore non exploitée dans de nombreux milieux industriels. Dans les machines de type Stirling, les écoulements du fluide de travail sont alternés. Bien que ces écoulements soient assez bien connus à l’échelle macroscopique, ils le sont très peu à échelle milli et sub-millimétrique. Or une bonne compréhension de ce type d’écoulement à ces échelles est primordiale lors des phases de dimensionnement et design des machines. Afin de contribuer à la caractérisation des écoulement alternés à ces petites échelles, des canaux dont les dimensions sont proches de celles de la machine miniature ont été réalisés par des moyens technologiques de microfabrication au sein de la centrale technologique MIMENTO de l'Institut FEMTO-ST. Les canaux réalisés ont un diamètre hydraulique variant entre 200 µm et 1 mm, un rapport d'aspect compris entre 0.1 et 1 et deux longueurs de canal différentes (25 mm et 50 mm). Des canaux avec des coudes ont également été réalisés afin d'étudier leur influence sur les caractéristiques de l'écoulement. Ces canaux ont ensuite été implémentés sur le banc expérimental. Dans un premier temps, l'étude a porté sur la caractérisation des écoulements permanents, dans la gamme de Reynolds de 15 à 510, dont les résultats, en accord avec ceux issus de la littérature, ont servi de référence pour l'étude d'écoulements alternés, menée par la suite dans une gamme de nombres de Womersley allant de 0.02 à 0.67.La caractérisation des écoulements alternés a permis de déterminer que le rapport d'aspect et le diamètre hydraulique des canaux affectent significativement l'écoulement. En revanche, les travaux issus de cette thèse ont montré que l'influence de la longueur du canal ainsi que la présence de singularités (coudes) sur les caractéristiques de l'écoulement ne semblent pas être aussi déterminantes qu'attendu.Parmi les paramètres testés au cours de cette thèse, il a été montré que le rapport d'aspect et le diamètre hydraulique des canaux sont des paramètres importants à prendre en compte dans le design de micro machines de Stirling, notamment afin de ne pas impacter considérablement son efficacité
This thesis focuses on the study of alternating flows within milli- and sub-millimeter-sized channels. The aim is to contribute to the optimization of a miniature (sub-millimeter dimensions) low-temperature (T < 200 °C) energy recovery and conversion machine based on the Stirling cycle principle. This is in line with the recovery of waste heat which is still not exploited in many industrial environments. In Stirling-type engines, the working fluid flows in alternating directions. Although these flows are fairly well understood on a macroscopic scale, very little is known about them on milli and sub-millimeter scales. However, a good understanding of this type of flow at these scales is essential for engine dimensioning and design. In order to contribute to the characterization of alternating flows at these small scales, channels with dimensions close to those of the miniature machine were produced using microfabrication technology. The channels produced have a hydraulic diameter ranging from 200 µm to 1 mm, an aspect ratio between 0.1 and 1, and two different channel lengths (25 mm and 50 mm). Channels with bends were also built to study their influence on flow characteristics. These channels were then implemented on the experimental bench. Initially, the study focused on the characterization of permanent flows, in the Reynolds range from 15 to 510, whose results, in agreement with those from the literature, served as a reference for the study of alternating flows, carried out in a second step with a Womersley number ranging from 0.02 to 0.67. The characterization of alternating flows has shown that the aspect ratio and the hydraulic diameter of the channels affect the flow significantly. On the other hand, this thesis has shown that the influence of channel length and the presence of singularities (bends) on the flow characteristics do not appear to be as decisive as expected. Consequently, among the parameters tested in this thesis, the aspect ratio and hydraulic diameter of the channels are important parameters to take into account for the design of the micro Stirling machine, especially to avoid impacting considerably its efficiency

Resumen
This study developed from an initial interest in the literature of the German exiles in which canon Klaus Mann's work between 1933 and 1945 figured prominently. This in turn evoked a curiosity toward this still relatively unknown son of Thomas Mann, intensified not least by the pathos of a life characterised by early promise, fame and prominence that ended in obscurity, despair and suicide. Yet these aspects of Klaus Mann's life appeared to have been overlooked by British scholars and with them the early and later years of Mann's career. The years of Mann's exile have been well documented and researched and place Mann's fiction of this time within the canon of Exilliteratur. Those texts which went before, however, have received only scant attention. Yet it is precisely in the novels and essays from the Weimar Republic that Mann developed and refined the techniques and themes that would define his later works. To overlook them is to suggest that the decisive moment of exile represented a caesura in Mann's career, thus masking the underlying continuity within Mann's oeuvre. For this reason, this study concentrates primarily on the early years of Mann's career, on the period from 1924 to 1933, to illustrate the progression and development within his work that would culminate in the novels of his exile. While Mann's prose dictates the approach I have taken, this is not exclusively 'literary' to the exclusion of all other concerns and potential external influences on his work. It assesses the complementary characteristics of Mann's fiction and his essayistic prose, much of which has only become readily available in the last five years, against the context of their creation during the Weimar Republic. In consequence, this work embraces the cultural, political and social context of this age, embracing its contradictory nature where progression and experimentation battled against the endemic regression and reaction of the Republic's institutions. However, it does not intend to provide a detailed discussion of the complexities that underlie this period of German history. For this I refer the reader to the body of research which deals specifically with this topic.

Resumen
Botho Strauß, source for polemic and target of vitriol over three decades, proposes an unsettling understanding of the poetic in his prose works, from his earliest writing to most recent publications. The thesis contends that this understanding of the poetic is deeply indebted to the late thought of Martin Heidegger: it investigates the nature of the debt, highlighting Strauß’ adoption and adaptation of ideas central to the philosopher, including his thinking on the work of art, technology, language and poetry. The body of the thesis examines Strauß’ views through detailed exegeses of Beginnlosigkeit, Wohnen Dämmern Lügen and Fragmente der Undeutlichkeit, while drawing extensively on other works and writing. The readings identify and elucidate a number of key terms critical to Strauß’ proposed poetic. Underpinning these terms, the thesis contends, and bound to the understanding of the poetic, is an ontological concern for philosophical truth derived from Heidegger. The thesis concludes that far from a retreat by Strauß into obscurantist mysticism and resignation from a putative cultural, social and political collective, accusations repeatedly levelled at him and here grouped under the rubric of fatalism, Strauß offers in and through his works a dynamic engagement with this conception of truth, which the thesis hypothesises as a poetics of dwelling.

Abstract This thesis is divided into four parts. First, the adsorption of formaldehyde (HCHO)、methanol(CH3OH) and formic acid (HCOOH) on Pt(111) and Pt(100) electrode surfaces was examined with cyclic voltammetry and in situ scanning tunneling microscope (STM) in 0.1 M HClO4. Ⅰ. Methanol on Pt(111) and Pt(100) The adsorption of methanol on Pt(111) electrode is so weak that experimental parameters such as supporting electrolyte and potential strongly affect the coverage and structures of methanol ad-molecules. For example, the coverage of methanol was less than one tenth of a monolayer within the potential region of 0.1 and 0.3 V in 0.1 M HClO4. Methanol ad-molecules were adsorbed randomly, producing island-like aggregations. The coverage of methanol indeed increased with more positive potentials, but no ordered structure was identified by high-resolution STM imaging. In contrast, STM molecular resolution reveals the formation of a highly ordered adlattice of (Ö2 ´ Ö2)R45° at 0.32 V in 0.1 M HClO4 upon the addition of methanol into the STM cell. This square lattice contains equally bright protrusions separated by a nearest neighbor spacing of 4 Å. These protrusions are likely to be methoxy (CH3) produced from dehydrogenation of methanol molecules upon their adsorption on Pt(100). This ordered array was gradually eliminated upon stepping potential positively to 0.5 V. Meanwhile, high resolution STM imaging shows the appearance of Pt(100) substrate lattice, suggesting that all methoxy species were completely oxidized to CO2. Formaldehyde on Pt(111) and Pt(100) In dilute (1 mM) HCHO, no adsorption was noted at both Pt electrodes in 0.1 M HClO4. Electroxidation of the hydrated formaldehyde, methylene glycol, and methanol produced peaks near 0.4 and 0.6 V in the voltammograms for both electrodes. Formyl like ad-species were adsorbed on both electrodes when [HCHO] ³ 10 mM. These adsorbates caused some delays in the electroxidation of methylene glycol, the predominant molecular form in aqueous formaldehyde solutions. This phenomenon is particularly pronounced for Pt(100), where the onset of oxidation shifted from 0.4 to 0.6 V for Pt(100) at a scan rate of 10 mV/s. The peak current due to electroxidation of methylene glycol on Pt(100) was nearly three times higher than that of Pt(111), indicating that the former was a more efficient catalyst for this reaction. High-quality in situ STM molecular resolution revealed highly ordered structures, identified as (Ö7 ´ Ö7)R19.1° and c(2 ´ 2), on Pt(111) and Pt(100), respectively, in the potential region between 0.1 and 0.3 V. The adsorption of hydrogen adatoms predominated to displace these two ordered arrays at negative potentials. The effect of potential on the adlayer was imaged by in situ STM, revealing high activity at step defects at low potential polarization, but a more universal reaction scheme at high polarization. These changes were reversible with respect to potential, i.e. ordered structures emerged again at more negative potentials. Formic acid on Pt(111) and Pt(100) The adsorption of formic acid on Pt(111) electrode surfaces was only partial in 0.1 M HClO4 , as revealed by the formation of islands on terraces. High resolution STM imaging reveals the each molecule appeared as a pair of bright spots, suggesting formic acid molecules were adsorbed via its two oxygen in the carboxylic acid group. The ordered structure is characterized as (2 ´ 2) with an intermolecular spacing of 5.6. The effect of scan rate on the morphology of the i-E profile was examined to elucidate the kinetics HCOOH electroxidation. Both positive and negative scans produce pronounced anodic current at potentials between 0.05 and 0.9 V. However, increasing scan rates from 50 to 500 mV/s produced marked differences between the profiles between 0.2 and 0.35 V, where protons discharge. Since the typical hydrogen features is observed at a 500 mV/s scan rate but not at 50 mV/s scan rate, it seems that the adsorption of formic acid was slower than that of hydrogen atoms. Ⅱ. Pb electrodeposition on Pt(111) Underpotential deposition of Pb adatoms results in patches of ordered structures, identified as (2´Ö3), on Pt(111) electrode. Deposition of Pb adatoms preferentially occurs at step edges, followed by lateral expansion of nucleation seeds as more Pb adatoms were deposited. However, the structure of Pb adatoms remained unchanged with deposition of Pb. Ⅲ. The adsorption of carbon monoxide on Pt(111) The goal of conducting in situ STM imaging of carbon monoxide on Pt(111) was to examine the stability of Pt electrodes and mobility of Pt atoms in CO-saturated perchloric acid. The potential of Pt(111) was set at 0.1 V, at which an ordered structure, characterized as (2 ´ 2), q = 0.75 ML, was imaged. Time-dependent STM images reveal that the adsorption of CO molecules yielded relocations of Pt atoms from near step ledges to terraces. STM shows that nearly all step ledges, irrespective of their orientation, became greatly zigzag, along with aggregation of Pt atoms into monoatomic high islands. It seems that the adsorption of CO molecules substantially reduced the binding energy, or greatly increased the mobility of Pt atoms located at step ledges. Ⅳ. The electroxidation of Pt(111) In situ STM was used to examine the restructuring of Pt surface induced by anodic oxidation at potentials positive of 1.6 V. This experiment was performed by conducting potential sweeping between 0 and 1.6 V. Topographic STM scans reveal terrace and step structures seen initially at Pt(111) electrode was nearly unchanged, but a high density of pits and islands were produced by the potential sweeping process. High resolution STM imaging was possible to discern an ordered Pt(111) atomic arrays on not only on terraces, but also on islands. It appears that anodic oxidation of Pt electrode caused displacement of Pt atoms from terraces, rather than steps. The present STM results clearly illustrate that the electric field at E > 1.6 V was strong enough to induce place-exchange between Pt and oxygen atoms. The numbers of islands and pits on terraces increased sharply with the numbers of potential cycling between 0 and 1.6 V.

In situ scanning tunneling microscopy (STM) and cyclic voltammetry (CV) have been used to examine the effect of 3-mercaptopropanesulfonate (MPS) and bis-3-sodiumsulfopropyldi-sulfide (SPS) on the electrodeposition of copper onto a well-ordered single crystalline electrodes of Pt(111) in 0.1 M HClO4. In situ STM imaging reveals atomically flat surface morphology of copper films deposited on ordered Pt(111) electrode, implying layer-by-layer growth mode of Cu in 0.1 M HClO4 + 1 mM Cu(ClO4)2 + 1 mM KCl. However, it implied islands growth mode of Cu with MPS or SPS-modified Pt(111). The MPS or SPS admolecules were adsorbed upright on Pt(111). The cyclic voltammetric results show that the MPS or SPS adlayer on Pt(111) would inhibit Cu deposition because the addition of MPS or SPS to the electrolyte of 0.1 M HClO4 + 1 mM KCl + 1 mM Cu(ClO4)2 reduced the amount of the Cu deposit, even in the presence of chloride. For MPS-modified and Cu-coated Pt(111) electrodes system, Cu film grew in smooth flakelike morphology. The deposition rate is 3D > 2D. The MPS admolecules readily formed a highly ordered molecular structure identified as (4 ×2 √3)rect on Pt(111) precoated with a monolayer of Cu adatoms and a ordered structure identified as (2 ×2) on thicker layers of Cu adatoms. For SPS-modified and Cu-coated Pt(111) electrodes system, Cu film also grew in flakelike morphology. But the processes of SPS adsorption varied greatly with the structures of the electrified interface of Pt(111) at 0.4 and 0.2 V (vs. Ag/AgCl), where Cu adatoms and chloride anions were coadsorbed in highly ordered arrays. The Cu-coated Pt(111) electrode was then exposed to a dosing solution containing SPS. In situ STM imaging revealed that the (4 × 4) - Cu + Cl bidlayer produced at 0.4 V was completely displaced by SPS molecules, resulting in MPS molecules adsorbed randomly on the Pt(111) electrode and cupric cations dissolving in the electrolyte. Incontrast, the Pt(111) - (√7 × √7)R19.1°–Cu + Cl structure produced at 0.2 V wasstable against the subsequently deposited SPS molecules, yielding locally ordered (4 × 4) –SPS structures residing on the Cu + Cl bilayer. With an overpotential η< 100 mV, bulk Cu deposition proceeded slowly and built up the Cu film in layers. Each Cu layer appeared to be atomically smooth and arranged in an ordered structure. Intriguingly, the second Cu layer was unique, because it adapted a square-like lattice, tentatively attributed to MPS molecules residing atop a pseudo Cu(100) network. As the Cu deposit thickened, in situ STM revealed a (2 × 2) structure, attributable to MPS admolecules sitting on a hexagonal Cu(111) lattice. MPS molecules could be produced by the reduction of SPS. Copper, chloride and MPS or SPS all need to be in a specific ratio and MPS or SPS-modified on Cu-coated Pt(111) electrode so that could accelerate Cu deposition. If MPS or SPS modified on Pt(111) even if at the specific ratio, the result will be inhibited the Cu deposition.

Resumen
The research carried out in the monograph aimed to create a measurement and interpretation system which is to obtain reliable results of well logging with the accuracy of laboratory measurements. Continuous core measurements allow for the generation of logging results without the impact of the borehole and facilitate the depth matching of the core to well log data. Four main chapters can be distinguished in this work: research methodology with a description of the devices used; partial results of core measurements made on various types of rocks; a proposal for a research system, and comprehensive data interpretation for selected boreholes. The methodological part concerned the description of the equipment for continuous measurements of cores in the field of natural gamma radioactivity (K, U, Th) with the application for bulk density measurements using the gamma-gamma method, X-ray fl uorescence spectrometers (XRF) for measuring the chemical composition of rocks and computed tomography (CT) for imaging of the core structure as well as determination of radiological density in Hounsfi eld units (HU). Rock studies were carried out on material representing formations of diff erent lithologies, such as shales, sandstones, limestones, dolomites, anhydrite, siltstones and heterolithic sandstone-siltstone-claystone complexes. The results of measurements made using individual methods have been described in detail and compared with the results of laboratory measurements and well logging data. Test measurements with data processing and interpretation were made on the cores from five boreholes (T-1, O-4, Pt-1, L-7, P-5H), whereas a comprehensive interpretation of the results was carried out for three other boreholes (J-1, P-4, T-2). The new methodology of spectral gamma measurements made it possible to obtain precise concentrations of potassium, uranium and thorium in rocks with high and low radioactivity. The results made it possible to standardise the archival gamma-ray logs made with the Russian-type probes from imp/min to API standard units and to obtain data on the content of K, U, and Th in the core intervals. Using the Cs-137 source in the device for the gamma equipment made it possible to carry out measurements of the bulk density in g/cm3 units. The lithological interpretation based on XRF measurements and mineralogical-chemical models allowed to obtain logs with increased resolution and a more signifi cant number of minerals than was the case with the interpretation of the well logging. In addition, it has been shown that the XRF measurement methodology can be used during the geosteering procedure. The results of the core tests using the CT computed tomography method were presented in combined images and continuous curves of density in HU units. The experience and the presentation of the full scope of measurement and interpretation workflow allowed to propose a procedure for conducting a full range of analyses, considering various types of material provided for research. The procedure considers the full range of analyses as well as the measurements of selected parameters depending on the client’s needs. Keywords: petrophysics, core analyses, XRF spectrometry, computed tomography, gamma profiling, lithological interpretation

Resumen
Abstract The scanning tunneling microscope (STM) was invented by Binnig and Rohrer (1982, 1987) and implemented by Binnig, Rohrer, Gerber, and Weibel (1982a, 1982b). Figure 1.1 shows its essential elements. A probe tip, usually made of W or Pt-Ir alloy, is attached to a piezadrive, which consists of three mutually perpendicular piezoelectric transducers: x piezo, y piezo, and z piezo. Upon applying a voltage, a piezoelectric transducer expands or contracts. By applying a sawtooth voltage on the x piezo and a voltage ramp on the y piezo,

Resumen
Building nonvolatile memory such as resistive random access memory (ReRAM) directly into a CMOS backend (BEOL) would reduce latency in connectivity-constrained devices and reduce chip’s footprint by stacking non-volatile memory (NVM) on top of the logic circuits. This co-integration is facilitated by a broad commonality between ReRAM and BEOL as both rely on the same basic metal–insulator–metal (MIM) structure. One good candidate for a ReRAM cell is the Cu/TaOx/Pt device. As platinum (Pt) is not an economic choice, a BEOL-compatible replacement is desirable. A good candidate to replace Pt electrode is ruthenium (Ru), currently being used as a liner/diffusion barrier in sub-15 nm technology nodes and soon to supplant tungsten as via, and copper (Cu) as interconnect materials. We report on extensive characterization of a Cu/TaOx/Ru device and compare its performance and reliability with extant ReRAM devices. Against the background of well-characterized non-Ru ReRAM devices, Cu/TaOx/Ru cell constitutes a micro-laboratory for testing a wide range of Ru properties with the Cu nanofilament as a probe. Since the temperature of the cell can be controlled internally from 27°C to ∼1100°C, thin Ru layers can be subjected to much more comprehensive tests than it is possible in the interconnect MIM structures and reveal and confirm interesting material properties, including the impact of embedment.

Resumen
A method of heat-assisted magnetic recording (HAMR) potentially suitable for probe-based storage systems is characterized. In this work, field emission current from a scanning tunneling microscope (STM) tip is used as the heating source. The tip is made of Ir/Pt alloy. Pulse voltages of 3–7 V with a duration of 500 ns were applied to a CoNi/Pt multilayered film. Written by a blunt tip (radius 1000 nm), marks are formed with a nearly uniform mark size of 170 nm when the pulse voltage is above 4 V. While sharp tip (radius 50 nm) writing achieves no mark. The emission area of our tip-sample system derived from an analytic expression for field emission current is approximately equal to the mark size, and is largely independent of pulse voltage. For the blunt tip, the emission region is almost the same as the mark size. While for the sharp tip, the initially formed mark is too small, so that the domain wall surface tension shrinks the mark and it crashes finally.

Resumen
Potential distribution in the electrolyte membrane in the MEA of PEFC has been measured in order to help understand a recently suggested membrane degradation mechanism caused by Pt band. A thin metallic probe, Pt or Au, is inserted in membrane to measure the potential distribution. The measured profile shows abrupt change at certain position, and the position is influenced by the operation and cell design parameters. A simple theoretical model to predict the potential distribution is developed and showed good agreement with experimental results.

Resumen
There is a variety of impressed current anode materials available for onshore applications, including High Silicon Cast Iron (HSCI), Mixed Metal Oxides (MMO), graphite, platinum (or platinum coated titanium), and conductive polymers. Many end users simply select the anode material that they have experience with. What is lacking is a clear, direct comparison of relative anode consumption rates conducted under identical conditions. The present study examined the behavior of the various anode types under different current loads and soil conditions in an effort to establish baseline consumption rates under controlled conditions. Variables that were examined included soil resistivity, the presence of coke backfill, current load, and soil type (sand or 50/50 clay/sand mix). The consumption rates of the anodes evaluated decreased in the order of: AnodeFlex, HSCI, Graphite, Pt, and MMO. A survey of field experiences yielded a slightly different order in terms of anode life with Graphite and HSCI lasting the longest. However, given the wide range of anode sizes used in the various field sites, it is difficult to directly link the field results to the consumption rates measured in the laboratory. Soil composition and resistivity were not observed to have a significant influence on anode consumption rates. The presence of coke, however, led to a decrease in consumption for all anodes in some cases by as much as a factor of nearly 70. Utilizing anode cost estimates and neglecting installation costs, the life-cycle material costs for MMO and Pt anodes are much lower than the other anode materials. Furthermore, AnodeFlex was noted to be the highest cost system from a materials perspective. This may be slightly misleading since installation and replacement costs are not factored in. Given that the installation of AnodeFlex is often much easier and less expensive than the other anode types, this may prove to be a viable financial decision when the other factors are considered. ����������� The primary implications of the present study are: Despite higher material costs, MMO and Pt anodes may offer significant long-term cost savings as compared to other anode types for many applications Use of coke backfill is critical to ensure lower anode consumption rates for AnodeFlex, Graphite, and to a lesser extent HSCI; coke does not appear necessary for MMO or Pt Soil composition (sand vs. clay/sand mix) and resistivity do not appear to significantly influence anode consumption rates, thus consideration of the soil environment (except groundwater chemistry) is not needed in selection of an appropriate anode Because the influence of groundwater chemistry (as part of the soil environment) was not examined, the effects of sulfate, chloride, and pH will need to be evaluated in detail to better aid in anode material selection Field use survey responses showed a wide range in observed anode lifespan, with graphite and HSCI experiencing the longest life and cable anodes the shortest The field survey also revealed that a significant cause of anode failures was connector and cable problems
