Download or read book Functional Electrodes For Enzymatic And Microbial Electrochemical Systems written by Nicolas Brun and published by World Scientific. This book was released on 2017-10-27 with total page 658 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bioelectrochemical Systems (BESs) are innovative and sustainable devices. They combine biological and electrochemical processes to engineer sensors, treat wastewater and/or produce electricity, fuel or high-value chemicals. In BESs, scientists have managed to incorporate biological catalysts, i.e. enzymes and/or microorganisms, and make them work in advanced electrochemical cells. BESs operate under mild conditions — at close to ambient temperature and pressure and at circumneutral pH — and represent a sustainable alternative to precious metal-based systems. Incorporating biological catalysts into devices while maintaining their activity and achieving electrical communication with electrode surfaces is a critical challenge when trying to advance the field of BESs.From implantable enzymatic biosensors to microbial electrosynthesis, and from laboratory-scale systems and fundamental studies to marketed devices, this book provides a comprehensive overview of recent advances related to functional electrodes for BESs. Suitable for researchers and graduate students of chemistry, biochemistry, materials science and environmental science and technology.

Available in PDF, EPUB and Kindle. Book excerpt: This book provides readers with basic principles of the electrochemistry of the electrodes used in modern, implantable neural prostheses. The authors discuss the boundaries and conditions in which the electrodes continue to function properly for long time spans, which are required when designing neural stimulator devices for long-term in vivo applications. Two kinds of electrode materials, titanium nitride and iridium are discussed extensively, both qualitatively and quantitatively. The influence of the counter electrode on the safety margins and electrode lifetime in a two electrode system is explained. Electrode modeling is handled in a final chapter.

Download or read book Mesoporous Platinum Electrodes for Solid Oxide Fuel Cells written by Andy Yun-Cheng Lin and published by Stanford University. This book was released on 2011 with total page 208 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solid oxide fuel cells (SOFCs) have long offered promise of renewable and highly efficient direct chemical to electrical energy conversion, though their high cost and operating temperatures have limited commercial adoption and applications. Recently, research efforts have focused on reducing the operating temperature by thinning the fuel cell membrane, thereby eliminating the requirement of high-temperature (800∘C to 1000∘C) compatible ceramic electrodes, and allowing the use of more traditional metallic catalysts that were previously limited to lower temperature fuel cell types due to materials compatibility constraints. However, because these operating temperatures (400∘C to 600∘C) remain much higher than those found in low temperature fuel cells, the morphological stability of these metallic catalytic electrodes at these intermediate temperatures is a critical factor impacting fuel cell performance. Our first study investigates the morphological stability of mesoporous platinum thin films deposited via nanosphere lithography on yttria-stabilized zirconia (YSZ). Carboxylate-modified polystyrene nanospheres were spin-coated onto YSZ substrates, diameter-reduced via reactive ion etching, and used as a shadow mask for e-beam platinum deposition. The spheres were then removed by sonication, leaving behind a hexagonal close-packed array of holes in the Pt film. Hole diameters were measured pre- and post-annealing in 5% forming gas and pure oxygen environments, mimicking the anode and cathode environments, respectively, of a fuel cell. Annealing temperatures and times were varied, and the hole evolution model by Srolovitz and Safran was used to extract an activation energy for platinum surface diffusion under each annealing environment. Calculated activation energies were 1.16 eV and 1.22 eV for forming gas and oxygen environments, respectively, with a slightly smaller diffusion prefactor for the latter environment. Our second study evaluates the performance of these mesoporous platinum films as SOFC electrodes. We compare the mesoporous platinum films to standard nanoporous platinum electrodes, using simple SOFC devices with 100 μm thick polycrystalline YSZ as the electrolytes. Four electrode configurations were investigated (noted as cathode-anode): nano-nano, meso-nano, nano-meso, and meso-meso. SEM images of the electrodes before and after testing are compared. We also evaluated the electrical performance of the electrodes by measuring current output as a function of time at constant voltage, current as a function of voltage, and impedance spectra pre- and post-constant voltage testing. The data suggest that, for these devices and operating conditions, oxygen reduction kinetics and cathode triple phase boundary lengths are the main factors limiting performance. Devices with nanoporous cathodes exhibited higher absolute current density compared to devices with mesoporous cathodes. The nanoporous cathode devices also exhibited decreasing current at constant voltage over time, whereas the mesoporous cathode devices reached a stable current after approximately 5 h. SEM images show that the nanoporous electrodes underwent significant morphological change during testing, as compared to the mesoporous electrodes and impedance spectra quantitatively show that the nanoporous cathode devices exhibit greater resistance increase after testing than the mesoporous cathode devices.

Book excerpt: A Comprehensive Reference for Electrochemical Engineering Theory and Application From chemical and electronics manufacturing, to hybrid vehicles, energy storage, and beyond, electrochemical engineering touches many industries—any many lives—every day. As energy conservation becomes of central importance, so too does the science that helps us reduce consumption, reduce waste, and lessen our impact on the planet. Electrochemical Engineering provides a reference for scientists and engineers working with electrochemical processes, and a rigorous, thorough text for graduate students and upper-division undergraduates. Merging theoretical concepts with widespread application, this book is designed to provide critical knowledge in a real-world context. Beginning with the fundamental principles underpinning the field, the discussion moves into industrial and manufacturing processes that blend central ideas to provide an advanced understanding while explaining observable results. Fully-worked illustrations simplify complex processes, and end-of chapter questions help reinforce essential knowledge. With in-depth coverage of both the practical and theoretical, this book is both a thorough introduction to and a useful reference for the field. Rigorous in depth, yet grounded in relevance, Electrochemical Engineering: Introduces basic principles from the standpoint of practical application Explores the kinetics of electrochemical reactions with discussion on thermodynamics, reaction fundamentals, and transport Covers battery and fuel cell characteristics, mechanisms, and system design Delves into the design and mechanics of hybrid and electric vehicles, including regenerative braking, start-stop hybrids, and fuel cell systems Examines electrodeposition, redox-flow batteries, electrolysis, regenerative fuel cells, semiconductors, and other applications of electrochemical engineering principles Overlapping chemical engineering, chemistry, material science, mechanical engineering, and electrical engineering, electrochemical engineering covers a diverse array of phenomena explained by some of the important scientific discoveries of our time.
