Abstract:

Redox reactions in live cells are generated by involving various redox biomolecules for maintaining cell viability and functions. These qualities have been exploited in the development of clinical monitoring, diagnostic approaches, and numerous types of biosensors. Particularly, electrochemical biosensor-based live-cell detection technologies, such as electric cell–substrate impedance (ECIS), field-effect transistors (FETs), and potentiometric-based biosensors, are used for the electrochemical-based sensing of extracellular changes, genetic alterations, and redox reactions. In addition to the electrochemical biosensors for live-cell detection, cancer and stem cells may be immobilized on an electrode surface and evaluated electrochemically. Various nanomaterials and cell-friendly ligands are used to enhance the sensitivity of electrochemical biosensors. Here, we discuss recent advances in the use of electrochemical sensors for determining cell viability and function, which are essential for the practical application of these sensors as tools for pharmaceutical analysis and toxicity testing. We believe that this review will motivate researchers to enhance their efforts devoted to accelerating the development of electrochemical biosensors for future applications in the pharmaceutical industry and stem cell therapeutics.

Abstract:

Three-dimensional organs and tissues can be constructed using hydrogels as support matrices for cells. For the assembly of these gels, chemical and physical reactions that induce gluing should be induced locally in target areas without causing cell damage. Herein, we present a novel electrochemical strategy for gluing hydrogel fibers. In this strategy, a microelectrode electrochemically generated HClO or Ca2+, and these chemicals were used to crosslink chitosan–alginate fibers fabricated using interfacial polyelectrolyte complexation. Further, human umbilical vein endothelial cells were incorporated into the fibers, and two such fibers were glued together to construct “+”-shaped hydrogels. After gluing, the hydrogels were embedded in Matrigel and cultured for several days. The cells spread and proliferated along the fibers, indicating that the electrochemical glue was not toxic toward the cells. This is the first report on the use of electrochemical glue for the assembly of hydrogel pieces containing cells. Based on our results, the electrochemical gluing method has promising applications in tissue engineering and the development of organs on a chip.

Abstract:

Sickle cell haemoglobin differs from normal haemoglobin by a single amino acid in its chain. This amino acid replacement, from glutamic acid to valine, causes polymerisation of proteins into defined long insoluble fibres with a typical diameter of 21.5 nm. The polymerisation is triggered by the formation of deox haemoglobin from oxyhaemoglobin in low oxygen partial pressures, which results in a conformational change in the secondary structure of the protein. Pathogenesis in sickle cell disease depends on the polymerisation and gelation of deoxygenated HbS molecules. In this work, an electrochemical method has been described to modulate the oxygen concentration in an optically transparent thin layer cell to produce deoxyhaemoglobin whilst monitoring the extent of polymerisation using turbidity measurements. The oxygen was depleted in the vicinity of the electrode and triggered the polymerisation. The dependence of protein concentration, temperature, pH and ionic strength on the nucleation and elongation of HbS polymerisation was characterised at the electrode surface and the kinetics of polymerisation was investigated using a model for fibrillogenesis describing a two-step process of nucleation followed by elongation. The rate constants, determined for a number of conditions, showed that nucleation is far slower than the growth whilst polymerisation at the surface was demonstrated to occur in three stages with an initial time delay when no structures were observed followed b growth of fibrous hair-like strands and finally gel-like aggregation. An understanding of the factors which affect polymerisation at a surface and an insight into the dynamics and mechanism of polymer aggregation and the pathophysiology of sickle cell disease has been provided. A screening method for substances that effect the fibre nucleation and/or growth that could be valuable to the pharmaceutical industry for treating sickle cell disease is also presented.

Abstract:

Magister Scientiae - MSc
Fuel cells convert chemical energy from a fuel into electricity through chemical reaction with oxygen. This possesses some challenges like slow oxygen reduction reaction (ORR), overpotential, and methanol fuel cross over in a direct methanol fuel cell (DMFC). These challenges cause inefficiency and use of higher amounts of the expensive platinum catalyst.Several binary catalysts with better ORR activity have been reported. In this study we investigate the best catalyst with better ORR and MOR performances and lower over-potentials for PEMFC and DMFC applications by comparing the in-house catalysts (10%Pt/C, 20%Pt/C,30%Pt15%Ru/C, 40%Pt20%Ru/C, 30%PtCo/C, 20%Pt20%Cu/C and 20%PtSn/C) with the commercial platinum based catalysts (10%Pt/C, 20%Pt/C, 20%Pt10%Ru/C, 20%PtCo/C,20%PtCu/C and 20%PtSn/C) using the cyclic voltammetry and the rotating disk electrode to determine their oxygen reduction reaction and methanol tolerance. HRTEM and XRD techniques were used to determine their particle size, arrangement and the atomic composition. It was observed that the 20%Pt/C in-house catalyst gave the best ORR activity and higher methanol oxidation current peaks compared to others catalysts followed by 20%Pt10%Ru/C commercial catalyst. The 20%PtCo/C commercial, 30%PtCo/C in-house and 20%PtSn/C in-house catalysts were found to be the most methanol tolerant catalysts making them the best catalysts for ORR in DMFC. It was observed that the ORR activity of 20%PtCo/C commercial and 30%PtCo/C inhouse catalysts were enhanced when heat treated at 350 0C. From XRD and HRTEM studies, the particle sizes were between 2.72nm to 5.02nm with little agglomeration but after the heat treatment, the particles were nicely dispersed on the carbon support.

Abstract:

Current environmental and energy sustainability trends have instigated considerable interest in alternative energy technologies that exhibit reduced dependence on fossil fuels. The advantages of such a direction are two-fold: reduced greenhouse gas emissions (notably CO2) and improved energy sustainability. Fuel cells are recognized as a potential technology that achieves both of these goals. However, improvements to fuel cell power density and stability must be realized to make them economically competitive with traditional, fossil-based technologies. The work in this dissertation is largely focused on the use of analytical tools for the study of transport processes in three fuel cell systems toward improvement of fuel cell performance. Polymer electrolyte membrane fuel cells (PEMFCs) are fueled by hydrogen and oxygen to generate electrical current. Microbial fuel cells (MFCs) use bacteria to degrade carbon compounds, such as those found in wastewaters, and simultaneously generate an electric current. Enzyme fuel cells (EFCs) operate similarly to PEMFCs but replace precious metal catalysts, such as platinum, with biologically-derived enzymes. The use of enzymes also allows EFCs to utilize simple carbon compounds as fuel. The operation of all three fuel cell systems involves different modes of ion and electron transport and can be affected negatively by transport limitations. Electrochemical impedance spectroscopy (EIS) was used in this work to study the distribution of transport resistances in all three fuel cell systems. The results of EIS were used to better understand the transport resistances that limited fuel cell power output. By using this technique, experimental conditions (including operating conditions, construction, and materials) were identified to develop fuel cells with greater power output and longevity. In addition to EIS, neutron imaging was employed to quantify the distribution of water in PEMFCs and EFCs. Water content is an integral aspect of providing optimal power output from both fuel cell systems. Neutron imaging contributed to developing an explanation for the loss of water observed in an operating EFC despite conditions designed to mitigate water loss. The findings of this dissertation contribute to the improvement of fuel cell technology in an effort to make these energy devices more economically viable.

Abstract:

Questa tesi si inserisce nel ramo di ricerca della Bioelettronica organica, in particolare l'obiettivo è quello di monitorare per via elettrica la formazione e la rottura di ricoprimenti e barriere cellulari. Queste sono di particolare importanza dal punto di vista biologico per il loro ruolo di protezione e per l'azione regolatrice nel passaggio di ioni e macromolecole necessarie al benessere dell'organo. Per fare questo sono stati utilizzati gli Organic ElectroChemical Transistor (OECT) basati sul polimero organico biocompatibile PEDOT:PSS. Per poter portare a termine questo lavoro il primo passo è stato lo sviluppo di un apparato sperimentale, detto TE-OECT (Tissue Engineering-Organic ElectroChemical Transistor), che permettesse l'acquisizione delle misure a bassa intensità di segnale dall'interno di un incubatore oltre alla trasparenza necessaria all'acquisizione di misure ottiche utilizzate come riferimento. Oltre allo sviluppo, l'ottimizzazione e la calibrazione dei dispositivi e del TE-OECT, è stato sviluppato un programma per l'elaborazione dei dati. Sono state misurate le risposte degli OECT in differenti fasi della crescita di due ricoprimenti cellulari (HeLa e NIH-3T3). Per validare le misure elettriche nelle varie fasi della crescita cellulare sono state acquisite immagini al microscopio dei ricoprimenti studiati. Come ulteriore conferma di quanto osservato è stata utilizzata la Tripsina per provocare il distacco dei ricoprimenti. Sono state eseguite misure elettriche durante il distacco per verificare se fosse possibile monitorare in tempo reale l'integrità dei layer cellulari. Questo tipo di analisi permette di ottenere utili informazioni aggiuntive sullo stato del ricoprimento cellulare e rende possibile svincolare l'efficacia di un agente patogeno o l'efficacia di un enzima utilizzato per il distacco cellulare dalle analisi di tipo ottico.

Abstract:

In this paper, the behavior of an anode-supported solid oxide fuel cell is studied by using voltage-current density measurement and electrochemical impedance spectroscopy. The cell total polarization obtained from electrochemical impedance spectroscopy results is shown to be consistent with the area-specific resistance calculated from the voltage-current density curve. An electrolyte-supported solid oxide fuel cell is then used to build an equivalent electrical circuit model using reference electrodes and electrochemical impedance spectroscopy. A four-constant phase element model is proposed to analyze the anode-supported solid oxide fuel cell. The model is used to evaluate an anode-supported solid oxide fuel cell under different cell voltages. The individual resistances are also studied as a function of applied voltage, and their physical meaning is explained in terms of reaction mechanisms occurring at the cathode and anode. It is shown that some of the obtained resistances are independent of diffusion while others have both a charge transfer and diffusion component.

Abstract:

This paper evaluates the potential for electrochemical hydrogen compression systems (EHCs) regarding their engineering performance, manufacturability, and capital costs. EHCs could enhance or replace mechanical hydrogen compressors. The physical embodiment of EHCs is similar to that of low temperature (LT) proton exchange membrane (PEM) fuel cell systems (FCSs). They also share common operating principles with LT PEM FCS and with PEM electrolysis systems. Design for Manufacturing and Assembly (DFMA™) analysis is applied to EHCs to identify manufactured designs, manufacturing methods, projected capital costs under mass-production, and cost drivers for both the EHC stack and the balance of plant (BOP). DFMA™ analysis reveals that EHC stack costs are expected to be roughly equal to EHC BOP costs, under a variety of scenarios. (Total EHC system costs are the sum of stack and BOP costs.) Within the BOP, the primary cost driver is the electrical power supply. Within the stack, the primary cost drivers include the membrane electrode assembly (MEA), the stamped bipolar plates, and the expanded titanium (Ti) cell supports, particularly at lower hydrogen outlet pressures. As outlet pressure rises, capital costs escalate nonlinearly for several reasons. Higher pressure EHCs experience higher mechanical loads, which necessitate using a greater number of smaller diameter cells and a greater tie rod mass. Higher pressure EHCs also exhibit a higher degree of back-diffusion, which necessitates using more cells per system.

Abstract:

A computational model of a cell-based microphysiometer is presented in this paper. The microphysiometer is a fluid based device that uses electrochemical sensors to measure the concentration of metabolites in the fluid medium around living cells. A computational code has been used to model the convective-diffusive transport in this system. This work focuses on modeling an oxygen electrochemical sensor. An ideal sensor model is used to study the effects of initial concentration and cell uptake rate on the sensor signal. In particular, the relative influence of the oxygen consumption by the sensor and the cells is examined. Removing the effect of the sensor allows isolation of cell behavior for various cell uptake rates and ranges of initial concentration. A preliminary comparison of computational results with experimental data is presented. The computational model provides very useful predictions of trends.

Both technologies are used to produce an “energy-in-transit.” Heat exchangers foster thermal transport (heat) as a result of thermal potential differences between streams; fuel cells foster charge transport across electrodes (current leading to power) as a result of electrochemical/electric potential differences between the reactant streams and fuel cell electrodes. Additional analogs include series resistance formulations, active regions for transport phenomena and pertinent capacity rates. These similarities have motivated the extension of heat exchanger design philosophies to fuel cells development. Pilot simulations have been done wherein solid oxide fuel cell geometries and process settings are being optimized via electrochemical pinch points, electroactive area optimization (patterned after optimal area allocation within heat exchangers), electrode “fins” for diminished polarization, and electrochemical multi-staging (motivated by heat exchanger network concepts). The prevailing theme has been to bridge methodologies from the mature field of heat exchanger design to improve fuel cell design practices.

Abstract:

The basis of electrochemical cell gas sensor technology is presented in the context of electrochemical cell portable analyzers for emissions testing of NOx and CO. This paper presents a modified test method approach and QA/QC criteria that supplement the project goal of assessing existing portable analyzer test methods and protocols for appropriate QA/QC requirements. The goal of a modified method is to minimize testing costs while ensuring data quality. The modified method leverages the inherent linearity of electrochemical cell technology, based on fundamental scientific principles, to employ single point calibration and order of magnitude span gases. Special considerations are included for �near zero� emissions testing (e.g., concentrations that are single digit parts per million by volume). Further demonstration and validation of a modified method through laboratory and field testing is recommended.

Abstract:

The purpose of this project was to generate an accelerated corrosion methodology capable of producing seven-strand cables with simulated corrosive defects for calibration of nondestructive analysis (NDA) techniques. An additively manufactured accelerated corrosion cell was motivated and designed. Previous attempts at accelerated electrochemical corrosion used a large cable area with a current density that was too low (i.e., 1 A/m²)* to effectuate efficient corrosion. The accelerated corrosion cell presented here takes advantage of the restricted area within the corrosion flow cell to maximize the corrosion rate in a consistent and calibrated manner (i.e., 2,000 A/m²).
