Abstract:
Nickel nanowire mesh electrodes offer great potential for water electrolysis in alkaline environment, given their high internal surface area, mechanical strength, and alkaline resistance. Here we use a nickel nanowire mesh with a specific area of 26 m2/cm3, resulting in ~100-fold area enhancement for a 4µm thick nanowire mesh, compared to planar nickel. This highly benefits geometric current density, potentially into a regime where mass transport is the main limiting factor. Therefore, we performed a systematic study of electrode behaviour under various mass transport conditions to decouple kinetic and mass transfer related contributions to electrode voltage losses. An electrochemical flow cell was designed to measure the nanowire mesh electrode performance under optimal mass transport conditions. The cell provided electrolyte flow through the nanomesh, enabling convective supply of reagent into the nanopores as well as convective removal of reaction products. Facilitated by the inherent strength of the nanowire mesh, superficial flow velocities up to 1 cm/s could be obtained, with which geometric current densities as high as 320 mA/cm2 could be measured in the kinetically limited (flowrate independent) regime. Internal mass transport limitations were isolated by use of an inverted rotating disk electrode (iRDE). Koutecky-Levich analysis was performed to compensate for external mass transfer contributions on both nanowire mesh electrodes and planar electrodes. The nanowire mesh as iRDE resembles operating conditions in an electrolyzer, whereas the planar electrode provides a well-defined benchmark area for the electrode surface activity. For both the oxygen evolution reaction as the hydrogen evolution reaction, mass transport limitations were studies as function of current density and electrolyte (NaOH) concentration. Nanowire mesh electrode operation in the presence of internal mass transport limitations was compared to the non-limited condition and planar benchmark, from which the electrode effectiveness factor could be calculated. A 1-d simplified model of the electrode was used to explain the observed phenomena and to provide guidance for design optimization.

Abstract:
This article presents the results of experimental studies on the influence of the geometry of high-voltage plasma actuator electrodes on the change in flow in the boundary layer and their influence on the change in the lift coefficient. The plasma actuator used in the described experimental studies has a completely different structure. The experimental model of the plasma actuator uses a large mesh ground electrode and different geometries of the high-voltage electrodes, namely copper solid electrodes and mesh electrodes (the use of mesh electrodes, large GND and HV is a new solution). The plasma actuator was placed directly on the surface of the wing model with the SD 7003 profile. The wing model with the plasma actuator was placed in the wind tunnel. All experimental tests carried out were carried out for various configurations. The DBD plasma actuator was powered by a high-voltage power supply with a voltage range from Vp = 7.5–15 kV. The use of a high-voltage mesh electrode allowed for an increase in the lift coefficient (CL) for the angle of attack α = 5 degrees and the air flow velocity in the range from V = 5 m/s to 20 m/s, while the use of copper electrodes HV with the plasma actuator turned off and on, were very small (close to zero). The experimental studies were conducted for Reynolds numbers in the range of Re = 87,985–351,939.

Abstract:
Ionic wind, which is generated by a corona discharge, is a promising field that offers significant advantages by directly converting electrical energy into kinetic energy. Because of the electrical characteristics of ionic wind, most studies aiming to improve the performance of ionic wind generators have focused on modifying the geometry of electrode configurations. A mesh-type electrode is one of the electrodes used as a collecting electrode in an ionic wind generator. Using a mesh electrode results in decreased momentum of the ionic wind and increased pressure drop due to frictional loss of the flow. In this study, to minimize the reduction in momentum, a mesh electrode with a central hole was proposed and investigated. Experiments were conducted with the configuration of a needle and mesh with the central hole. These experiments analyzed the effect of the central hole diameter and the distance between the needle and the mesh electrodes on the electrical and physical characteristics of the ionic wind. The addition of the central hole led to a higher average velocity and lower current, thus resulting in increased energy conversion efficiency. The presented configuration offers a simple geometry without electrical and physical interference from complex configurations, and it is considered to have the potential to improve energy conversion efficiency and optimize ionic wind flow.

Abstract:
The ?corrected accelerated service life test for hydrogen evolution reaction? (CASLT-HER), designed for application of certain electrode materials as cathodes in the cell for alkaline water electrolysis in 30 % KOH at 80 ?C, was performed at electrodeposited NiSn alloy and Ni 40 mesh electrodes. The Ni 40 mesh was slightly etched, while the NiSn alloy coating was electrodeposited from the bath containing pyrophosphate, glycine, SnCl2 and NiCl2 onto Ni 40 mesh to the thickness of approximately 40 ?m. It is shown that the NiSn cathode possess from maximum 0.77 V to minimum 0.30 V better overpotential than the Ni 40 mesh electrode during the 5 years of their exploitation at the conditions of industrial alkaline water electrolysis. It is also shown that both electrodes should be held at j = ?0.3 A cm-2 for at least 5 h in order to establish stable overpotential response. The limiting overpotential values for applying cyclic voltammetry (CVs, to mimic ?polarity inversion?) should be determined in a separate experiment before the CASLT-HER and should be adjusted during the application of CVs.

Abstract:
Reverse electrodialysis (RED) is a type of salinity gradient power generation technology that is a renewable energy source that converts chemical energy into electrical energy. RED uses seawater and salt differences to produce electrical energy. Intensive research is needed to develop electrodes with excellent conductivity to reduce electrode resistance and increase performance when operating reverse electrodialysis. Conventionally, the state of the art electrode is prepared by electrodepositing Pt on metal substrate, such as Ti mesh (Pt/Ti mesh) in acidic medium. However, due to the dimension of porous mesh structure, it is difficult to form an uniform Pt layer with high coverage via normal potential- or current-controlled electrodeposition. In response to this, this research proposes an additive-induced electrodeposition for the preparation of Pt/Ti mesh electrode. A trisodium citrate (TSC) is chosen to be an additive. TSC plays both as a leveler and a suppressor and therefore it helps to control the kinetics of electrochemical process. The effect of TSC and its content on the physicochemical and electrochemical property of Pt/Ti electrode is addressed. The RED single cell test is conducted with the electrodes manufactured according to the TSC content, and the performance is compared and analyzed accordingly.

Abstract:
In this work, modified nano-mesh structured Mn-based oxide electrode material and the supercapacitors are researched. Three types of conducting polymers, i.e. polyaniline (PANI), polypyrrole (PPy) and polythiophene (PTs) are considered to modify Mn-based oxide electrodes. The results of field emission scanning electron microscope show that conducting polymer film can form porous structure on Mn-based oxide electrode, this special structure is beneficial to the improvement of specific surface area, so that the specific capacitance can be increased. The specific capacitance of the supercapacitors assembled by Mn-based oxide/conducting polymer composite electrodes are tested, resulting that the maximum initial specific capacitance is 843 F g-1, cycle life is 105 times. Compared to supercapacitors assembled by general Mn-based oxide electrodes, this Mn-based oxide/conducting polymer material electrode can improve the specific capacitance up to 1.4~1.9 times, and the conductivity and cycle stability can be increased at the same time.

Abstract:
We prepare transparent, selfassembled polygonal silver nanowire (AgNW) mesh by bubble template and use as top electrode for a poly (3,4ethylenedioxythiophene):poly(stylenesulfonate) (PEDOT:PSS)/n-Si hybrid solar cell. Devices were fabricated by pressing the self-assembled AgNW and ITO electrodes onto the surface of the PEDOT:PSS and device performances were compared. In identical transmittances of ITO and self-assembled AgNW (i.e., 87% transmittance at wavelength of 550 nm), the self-assembled AgNW mesh electrodes shows lower sheet resistance (8 Ω/square) with enhanced transparency in the ultraviolet and infrared regions. As a result, a device performance with an efficiency of 9.60% was obtained with the self-assembled electrode compared to 9.07% efficiency from the indium–tin oxide (ITO) electrode under 100 mW/cm2 of AM 1.5 illumination. This study suggests the potential application of a self-assembled AgNW electrode as the transparent conducting electrode for future optoelectronic devices.

Abstract:
Abstract The electrorheological (ER) valve with parallel electrodes structure has an inherent characteristic. The electrodes gap is the same as its flow channel gap, which causes a strong coupling relationship between the applied voltages and the flow rates of the ER valve. If flow rates of ER valves in the condition of turn on operational mode were increased, their applied voltages were increased necessarily for keeping their shutdown operational mode, which brings a bunch of problems of product costs and dimensions, especially when multiple ER valves with different operational modes work together, such as application of ER valves matrix used in 2D matrix displays. The mesh electrodes structure can decouple the relationship between the electrodes gap and the flow channel gap of parallel electrodes structure. However, due to the complexity of mesh electrodes structure, a mathematic model is difficult to be established theoretically. And, a mathematic model of ER valve with mesh electrodes plays a vital role in designing its controller. By analyzing the composition elements of an ER valve with mesh electrodes, a semi experimental model was established using the parametric identification toolbox of MATLAB. The consistency between the output of recognition model and the output of validation data reaches 93.46%. Subsequently the PID controller for ER valves with mesh electrodes was designed to meet the operational demands of a 2D matrix display using Simulink. The constrain of simulation was that the pressures of flow channel inlets of ER valves, the dynamic responses of ER valves with mesh electrodes kept stable and within its operational range. The results will be helpful for applications of ER valves with mesh electrodes.

Abstract:
Zinc mesh electrode was proposed for creating a prototype of an electrochromic device capable of recuperating energy spent on coloration. The search for a suitable formation regime of the mesh electrode with required capacity was realized using several approaches: use of multiwire substrates, deposition of zinc from different electrolytes, change in the composition of pasted electrodes. Deposition of zinc from a simple sulfate electrolyte yielded good deposits, however, their capacity wasn’t sufficient. The use of the alkaline zincate electrolyte yielded deposits with developed surface and higher capacity, but the deposits had dark color, poor adhesion and were falling off the substrate. The pasted electrode with a paste of zinc oxide, graphite and polyvinyl butyral demonstrated the highest capacity of – 0.83 mA∙h. The proposed method for forming the zinc mesh electrode was used to develop a prototype of electrochromic devices capable of recuperating electrical energy. The assembled prototype with the described electrodes demonstrated stable characteristics at a coloration degree of 50 %. The prototype was also capable of working as an energy storage unit and was used to power an LED

Abstract:
Indium thin oxide (ITO)-free planar perovskite solar cells (PSCs) were fabricated at a low temperature (150 °C) in this work based on the transparent electrode of photolithography processed nickel/gold (Ni/Au) mesh and the high conductivity polymer, PH1000. Ultrathin Au was introduced to increase the conductivity of metal mesh, and the optimal hexagonal Ni (30 nm)/Au (10 nm) mesh (line width of 5 μm) shows a transmittance close to 80% in the visible light region and a sheet resistance lower than 16.9 Ω/sq. The conductive polymer PH1000 not only smooths the raised surface of the metal mesh but also enhances the charge collection ability of metal mesh. The fabricated PSCs have the typical planar structure (glass/Ni-Au mesh/PH1000/PEDOT:PSS/MAyFA1−yPbIxCl3−x/PCBM/BCP/Ag) and the champion PSC (0.09 cm2) obtains a power conversion efficiency (PCE) of 13.88%, negligible current hysteresis, steady current density and PCE outputs, and good process repeatability. Its photovoltaic performance and stability are comparable to the reference PSC based on the ITO electrodes (PCE = 15.70%), which demonstrates that the Ni/Au mesh transparent electrodes are a promising ITO alternative to fabricate efficient PSCs. The relatively lower performance of Ni/Au based PSC results from the relatively slower charge extraction and stronger charge recombination than the ITO based PSC. Further, we tried to fabricate the large area (1 cm2) device and achieve a PCE over 6% with negligible hysteresis and steady current density and PCE outputs. The improvements of perovskite film quality and interface modification should be an effective approach to further enhance the device performance of Ni/Au based PSCs, and the Ni/Au mesh electrode may find wider applications in PSCs and flexible devices.

Abstract:
A hybrid stochastic-deterministic method, COMET-PE, is developed for dose calculation in radiotherapy. Fast, accurate dose calculation is a key component of successful radiotherapy treatment. To calculate dose, COMET-PE solves the coupled Boltzmann Transport Equations for photons and electrons. The method uses a deterministic iteration to compose response functions that are pre-computed using Monte Carlo. Thus, COMET-PE takes advantage of Monte Carlo physics without incurring the computational costs typically required for statistical convergence. This work extends the method to 3-D problems with realistic source distributions. Additionally, the performance of the deterministic solver is improved, taking advantage of both shared-memory and distributed-memory parallelism to enhance efficiency. To verify the method’s accuracy, it is compared with the DOSXYZnrc (Monte Carlo) method using three different benchmark problems: a heterogeneous slab phantom, a water phantom, and a CT-based lung phantom. For the slab phantom, all errors are less than 1.5% of the maximum dose or less than 3% of local dose. For both the water phantom and the lung phantom, over 97% of voxels receiving greater than 10% of the maximum dose pass a 2% (relative error) / 2 mm (distance-to-agreement) test. Timing comparisons show that COMET-PE is roughly 10-30 times faster than DOSXYZnrc. Thus, the new method provides a fast, accurate alternative to Monte Carlo for dose calculation in radiotherapy treatment planning.

Abstract:
In this work, the design and implementation of a Multi-Experiment Spectral Suite (MESS) is described. The MESS currently contains two time-resolved experiments - Transient Absorption (TA), and Second Harmonic Generation (SHG) - but has been designed with a view to expansion. The primary species of interest to be studied is the hydrated electron. As an electron is generated during water ionization, its hydrated form is significant within many scientific processes including, but not limited to, biological chemistry and tissue damage, atmospheric chemistry and nuclear chemistry. However, the majority of what is known about the hydrated electron is its behaviour in a bulk solvation environment with little understanding known about its behaviour at interfaces where it reacts in most instances. The MESS provides the ability to build a bottom up picture of solvation environment on molecular dynamics in going from the bulk (TA) to the interface (SHG). SHG enables the study of interfacial dynamics due to its inherent surface sensitivity. The method described here is an improvement on a previous phase-sensitive SHG technique that varied the phase of the interference between the SHG from a sample (ESHG) and a local oscillator (ELO) manually by incrementally changing the distance between the sample and reference sample. The new technique presented here is able to record the entire interference pattern in a single shot by using a phase varying unit comprised of a Reference Surface sandwiched between two glass wedges. The technique is characterised in this work by studying the excited state dynamics of malachite green at the air/water interface, exhibiting excellent phase stability and sensitivity and comparatively short acquisition times. In comparison, the TA technique presented is experimentally simpler than SHG. The excited state dynamics of molecules are studied in which a pump pulse induces an excitation which is then probed by a white light pulse spanning 520-950 nm continuously. In combination with 30 kHz modulation of the laser, shot-to-shot pump-probe measurements are presented for both SHG and TA techniques.

Abstract:
碩士<br>國立交通大學<br>電信工程研究所<br>103<br>Energy harvesting is the process of scavenging energy from ambient energy sources in environment to serve as power supply for low-power electronics devices. By Micro-Electro-Mechanical System (MEMS) fabrication technology, energy harvesting system can be integrated with low-power devices. For invasive devices in biomedical applications, batteries are discouraged due to its cost of operations for replacement. Therefore, energy harvesting is more suitable then batteries for low-power devices. Human motion which is usually complicated and aperiodic can be an energy source. Flexible energy harvesters can scavenge energy from human motion by attaching them to human bodies, and power up low-power devices. In this thesis, electrostatic flexible electret energy harvesters for human motion are proposed. For flexibility and biocompatibility, the substrate was polydimethylsiloxane (PDMS) and Parylene C was used as electret. In our previous work, the sputtered electrode were prone to cracks upon the deformation of the devices, thus limiting the lifetime. To improve the reliability, flexible electret energy harvesters with embedded copper mesh are proposed. In this thesis, two prototypes of energy harvesters have been fabricated. Prototype I has square spacer of rings and is suitable for harvesting energy from walking. Prototype II has arrays of spacer posts and is suitable for harvesting energy from finger typing. The output power for the two prototypes were 3.15 μW and 2.26 μW, corresponding to power density of 15 μW/cm3 and 23 μW/cm3 at test frequency of 20 Hz with a 1000-MΩ load, respectively. In human motion test, the harvester was attached to a human finger. With a 1000-MΩ load, the output power were approximately 300 nW for finger tapping, and 5 nW for finger bending.

碩士<br>國立臺灣科技大學<br>材料科學與工程系<br>105<br>Transparent conductive oxide (TCO) electrodes find application in a wide variety of devices, like light-emitting diodes, displays and solar cells. TCOs however are not suitable for high temperature manufacturing processes like CIGS (Copper Indium Gallium Diselenide) thin film processing, which takes place at 500°C to 600°C and suffer from a number of different drawbacks. The electrode on which CIGS is deposited must be stable at these temperatures. To realize a tandem cell, both, front and back contact of a cell must be transparent. In this work a molybdenum metal mesh electrode with four pattern derivatives is presented, which are designed towards this implementation in a tandem cell setup. The electrode consists of 2 micron wide fingers arranged in an industry typical H-grid pattern and in a hexagonal shaped pattern, with each of these patterns being comprised of a derivative with and without tapered busbars. The electrode’s micro structure, crystal orientation, surface roughness, electrical properties and optical properties are investigated. The manufacturing process as well as a comparison of this works electrodes with various competing electrode types is also presented. All electrode derivatives show excellent transmittance of up to 97% within and beyond the visible spectrum while retaining acceptable sheet resistances of about 30 Ω/□.

Abstract:
碩士<br>國立中央大學<br>機械工程學系<br>105<br>This thesis aims at developing a fabricating technique for metal-mesh transparent electrodes. The approach includes the uses of the screen printing method for patterning metal mesh on a glass substrate and the lift-off method for embedding the printed mesh into a flexible polyimide substrate. As the screen printing is a fast and straightforward mass production method, it has the potential for replacing the current time and energy consuming vacuum coating process. The first part of this thesis discusses the basic characteristics of the fabricated metal mesh transparent substrate, including the metal mesh design, light transmission, bending life and other related characteristics. The second part is to coat the embedded mesh electrode with a layer of conductive polymer, PEDOT:PSS, as a modifying flat layer for reducing the surface roughness of the electrode. In order to further improve the photoelectric properties of the metal-mesh electrode, different proportions of MoOx and silver nanoparticles are blended with the PEDOT:PSS by mixing PEDOT:PSS solution with aqueous MoOx and silver nanoparticles solutions. The resulting effects are examined by characterizing a Hole-only device (HOD). By employing the developed metal mesh electrode as the anode of an organic light emitting diode (OLED), the third part of this thesis discusses its feasibility.

Abstract:
碩士<br>國立清華大學<br>動力機械工程學系<br>102<br>Transparent conductive films has been widely used in solar cells, LED and consumer electronics as a medium of electric current and light. Its conductivity and transmittance affect the efficiency of these devices. The mainstream material for transparent conductor is ITO (indium tin oxide) in recent years. However, the price of ITO has increased dramatically due to the huge demand and the strained supply of indium. Seeking the replacement materials for ITO becomes an important issue, and the way how to fabricate a transparent conductor with comparable conductivity and transmittance under the same cost is the only solution. This study presents a transparent mesh-type electrode by integrating inkjet-printed-silver and modified conductive polymer (PEDOT). A mathematical model has been proposed for calculating the optimized grid pattern, and the optimized line width/line spacing ratio is 0.05 by this model. Furthermore, the theoretical relationship between line width/line spacing ratio and figure of merit has been verified by experimental results. For improving the conductivity of electrodes, the aspect ratio of lines has been raised by overprinting. The conductivity of four-layers printed electrodes is 50 times as high as the conductivity of monolayer printed electrode, and their transmittance are still higher than 90%. Moreover, planarization of transparent mesh-type electrodes by hot-pressing has been proposed and demonstrated. The thickness of grid lines decreases from 150 nm to 10 nm by this planarization. Integrating all of these processes, the sheet resistance of fabricated electrode is 7.2 Ω/□, the transmittance is 84.03 % and the figure of merit is 24.39×10-3 Ω-1 which is 2 times as high as the mean value of the literature before. After 23000 times of bendings to a 11 mm radius curvature, the resistance incensement of electrode developed by this study is still less than 10%.

Abstract:
This work presents a comprehensive multiscale model for Solid Oxide Fuel Cells (SOFCs), integrating microscale and macroscale simulations to analyze internal reforming and its impact on overall cell performance. The microscale model [1], [2] captures the intricate mass and charge transport phenomena at the pore scale of porous electrodes, resolving electrochemical reactions at the triple-phase boundaries and modeling chemical reactions at pore spaces. Simultaneously, the macroscale model provides a broader view of the entire cell's behavior by solving the same transport equations on a coarser computational mesh. The multiscale approach is particularly useful for addressing the challenges posed by simultaneous chemical and electrochemical reactions at the anode, which complicate the modeling of internal reforming. To overcome these challenges, a novel approach is introduced [3], spatially separating the regions of chemical and electrochemical activity in the pore scale domain by taking the electrochemical active layer thickness into consideration. The integrated multiscale model is applied to a complete internal reforming SOFC to explore how electrode morphology, particularly the use of gradient microstructures, influences cell performance.

Abstract:
Abstract High levels of chloride were found in cross head beams on a motorway bridge in the northwest of England. The design made access for testing repair and protection difficult as steel buried up to 800mm deep within the cross head was exposed to high levels of chloride. Tests and trials were carried out to see to what extent the inaccessible steel could be cathodically protected from a surface applied anode. After successful trials, a full impressed current cathodic protection system was installed using a mixed metal oxide titanium mesh anode with a shotcrete overlay. Detailed calculations of steel surface areas and current requirements were carried out. After nine months of monitoring, it is apparent that the system could have been designed assuming a maximum current density requirement of less than 10mA/m2 of steel surface area rather than the 20mA/m2 used in the design. Embedded reference electrodes 700mm deep in concrete measured polarization of steel 800mm from the anode on the surface. This showed that embedded probe anodes were not required to protect the highly congested steel deep inside the cross head.

Abstract:
Abstract Relatively little information is available on corrosion of materials in marine environment under the influence of AC fields. In this study, corrosion caused by sinusoidal alternating voltage (AV) fields in 1018 carbon steel is investigated by: (i) immersion tests, (ii) DC polarization experiments, and (iii) characterization of corrosion products. The experimental data show that under the influence of alternating voltage (60 Hz) applied between carbon steel and a platinum mesh counter electrode, the corrosion rate of the carbon steel increases with the applied voltage then decreases as the peak voltage is increased in the range of 100-600mV. However, with a further increase in the voltage beyond 600mV, the corrosion rate is observed to increase exponentially. It is speculated that the decrease in the corrosion rate is related to a passivation phenomena brought about by an increase in the pH of the diffusion layer. The influence of the pH on the carbon steel corrosion properties is also investigated. The effect of frequency of AV signal on corrosion rate is also determined and discussed.

Abstract:
Abstract This work presents a comparison of the effect generated by a mixed culture of sulfate-reducing bacteria (SRB) isolated from a natural estuary in western Venezuela, on the cathodic protection (CP) of carbon steel under simulated blisters. The laboratory study was carried out simultaneously measuring attack morphology, polarized potential, pH, and sessile growth, inside a simulated blister in a special cell arrangement, using two types of coatings: one 100% solids epoxy, and the other one, a tape type, which consists of the combination of a geo mesh-polypropylene textile and tarred rubber. A potential of -3.2 V vs. Copper Sulfate Electrode (CSE) was applied, which allowed to reach polarized potentials more negative than -950 mV Vs. CSE without the presence of coatings. Various conditions were considered for the study: A) sterile medium, B) sterile medium inoculated with SRB only outside the blister, and C) sterile medium inoculated outside and inside the blister. The correlation of the results for each cases allowed the establishment of different comparative tables that could help to improve corrosion management methods of buried or submerged pipelines in presence of SRB. In all cases, a decrease in CP efficiency under the blister was demonstrated.
