Available in PDF, EPUB and Kindle. Book excerpt: This dissertation focuses primarily on the fabrication of micro and nanoscale electrochemical structures such as electrodes, electrode arrays, and nanopores. It also discusses the use of these tools in studying nanoscale electrochemical processes such as geometric considerations in redox molecule diffusion to nanoscale electrodes, confined diffusion within electrode arrays, nanoparticle transport, and emulsion droplet transport and agglomeration. There is an introduction to electrochemistry followed by considerations to make when studying electron transfer at the nanoscale using voltammetric and amperometric measurements. Chapter 2 discusses three types of new nanoelectrodes that have been developed. These nanoelectrodes are different from previous nanoelectrodes in their materials and fabrication methods. Chapter 3 introduces the reader to electrode arrays and their properties. A new way of fabricating microelectrode arrays with high density and a nearly 100% success rate in terms of electrode activity is presented. In Chapter 4 a new electrochemical imaging technique developed in our lab is introduced. This new technique requires bipolar electrode arrays, new variants of which are fabricated using several methods which are discussed. Chapter 5 moves away from Faradaic current measurements toward ionic current measurements of nanoparticles. Emulsified oil droplets are monitored with ionic current measurements and fluorescence imaging to reveal their interactions at a nanopore. In Chapter 6 a new method for fabricating nanopores is outlined along with substantial experiments and finite element simulations to describe their properties. The ability of this new nanopore to measure nanoparticles is illustrated through resistive-pulse sensing. These new nanopores are compared with another type of nanopore using both experiment and simulation.

Download or read book Electrocatalytic and Fundamental Properties of Nanoscale Materials and Development of New Nanoscale Electrochemical Methods written by Stephen J. Percival and published by . This book was released on 2015 with total page 244 pages. Available in PDF, EPUB and Kindle. Book excerpt: This dissertation mainly discusses the fundamental properties and electrocatalytic activity of single, isolated nanomaterial structures, such as nanowires, nanoparticles and graphene. It also discusses the development of new nanoscale electrochemical techniques to investigate various aspects of heterogeneous catalysis and single cell analysis. There is a brief introduction about the nature of electrochemistry and electrochemical catalysts as well as some various nanomaterials and voltammetric techniques involved in this work. The fabrication and of new ultralong metal nanowires made from platinum or gold through a laser assisted mechanical pulling procedure is discussed in chapter 2. Single platinum nanowires of this type are then used to study the Oxygen Reduction Reaction (ORR) on nanowires with various diameters in Chapter 3. The catalytic activities of several different nanoparticles are studied in Chapters 4 and 5 using the technique of Fast Scan Cyclic Voltammetry (FSCV), where detailed chemical information can be obtained from nanoparticle collision events by recording single nanoparticle Cyclic Voltammograms (CVs) for the oxidation of hydrazine. Combined with numerical simulations, the single nanoparticle CVs allow for the determination of the electron transfer kinetics and the Gibbs free energy of activation for hydrazine oxidation. These combined methods can be a powerful tool in many aspects of fundamental catalytic research. Chapter 6 details the phenomena of fast formation and growth of platinum oxide at low anodic potentials using platinum nanoelectrodes as model nanoparticle electrocatalysts. Chapter 7 discusses the technique of Fluorescence Enabled Electrochemical Microscopy (FEEM) and its application towards heterogeneous electrocatalyst screening, where a fluorogenic reaction is monitored at one side of an array of closed bipolar electrodes, which is coupled to a reaction occurring at the same region on the other side of the array. Chapter 8 is a study of the electrocatalytic activity of single graphene sheets with different numbers of layers for the ORR. The testing of recessed ring disk electrodes for the purpose of molecular scavenging during single cell exocytosis experiments is presented in Chapter 9 and chapter 10 describes the design and fabrication of two different Transmission Electron Microscopy (TEM) chip based electrodes for the goal of in-situ TEM experiments.

Download or read book Research Opportunities in Corrosion Science and Engineering written by National Research Council and published by National Academies Press. This book was released on 2011-01-27 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of corrosion science and engineering is on the threshold of important advances. Advances in lifetime prediction and technological solutions, as enabled by the convergence of experimental and computational length and timescales and powerful new modeling techniques, are allowing the development of rigorous, mechanistically based models from observations and physical laws. Despite considerable progress in the integration of materials by design into engineering development of products, corrosion considerations are typically missing from such constructs. Similarly, condition monitoring and remaining life prediction (prognosis) do not at present incorporate corrosion factors. Great opportunities exist to use the framework of these materials design and engineering tools to stimulate corrosion research and development to achieve quantitative life prediction, to incorporate state-of-the-art sensing approaches into experimentation and materials architectures, and to introduce environmental degradation factors into these capabilities. Research Opportunities in Corrosion Science and Engineering identifies grand challenges for the corrosion research community, highlights research opportunities in corrosion science and engineering, and posits a national strategy for corrosion research. It is a logical and necessary complement to the recently published book, Assessment of Corrosion Education, which emphasized that technical education must be supported by academic, industrial, and government research. Although the present report focuses on the government role, this emphasis does not diminish the role of industry or academia.

Download or read book Electrochemical Surface Science Basics and Applications written by Gaetano Granozzi and published by MDPI. This book was released on 2019-10-07 with total page 398 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrochemical surface science (EC-SS) is the natural advancement of traditional surface science (where gas–vacuum/solid interfaces are studied) to liquid (solution)/electrified solid interfaces. Such a merging between two different disciplines—i.e., surface science (SS) and electrochemistry—officially advanced ca. three decades ago. The main characteristic of EC-SS versus electrochemistry is the reductionist approach undertaken, inherited from SS and aiming to understand the microscopic processes occurring at electrodes on the atomic level. A few of the exemplary keystone tools of EC-SS include EC-scanning probe microscopies, operando and in situ spectroscopies and electron microscopies, and differential EC mass spectrometry (DEMS). EC-SS indirectly (and often unconsciously) receives a great boost from the requirement for rational design of energy conversion and storage devices for the next generation of energetic landscapes. As a matter of fact, the number of material science groups deeply involved in such a challenging field has tremendously expanded and, within such a panorama, EC and SS investigations are intimately combined in a huge number of papers. The aim of this Special Issue is to offer an open access forum where researchers in the field of electrochemistry, surface science, and materials science could outline the great advances that can be reached by exploiting EC-SS approaches. Papers addressing both the basic science and more applied issues in the field of EC-SS and energy conversion and storage materials have been published in this Special Issue.
