Bard and published by . This book was released on 1986 with total page 61 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diffusion to arrays of closely spaced (1.2 micron to 0.2 micron) ultramicroelectrodes (50 micron x 2.3 micron) was studied by digital simulation and experimentally by examing the redox behavior of Ru(NH3)6(3+) in H2O. Cylindrical diffusion of solution species resulted in quasi-steady-state currents at the microband electrodes. Generation-collection experiments, analogous to rotating ring-disk collection experiments, resulted in larger generator currents than those observed at a single microelectrode due to the back diffusion of products to the neighboring microelectrode. A collection efficiency of 93% was observed for the re-oxidation of Ru(NH3)6(2+) generated at a central microelectrode 0.2 micron from two flanking collector microelectrodes. This experiment as well as generator-single collector electrode pairs was simulated at a two-dimensional rectangular expanding grid and yielded results in good agreement with the experiment. Predictions of the model that the collection efficiency principally depends on the gap size, rather than electrode width, were tested experimentally. The novel application of microelectrode arrays to the study of the follow-up reactions of electrogenerated intermediates is demonstrated. (Author).

Download or read book Digital Simulation in Electrochemistry written by Dieter Britz and published by Springer. This book was released on 2016-05-09 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explains how the partial differential equations (pdes) in electroanalytical chemistry can be solved numerically. It guides the reader through the topic in a very didactic way, by first introducing and discussing the basic equations along with some model systems as test cases systematically. Then it outlines basic numerical approximations for derivatives and techniques for the numerical solution of ordinary differential equations. Finally, more complicated methods for approaching the pdes are derived. The authors describe major implicit methods in detail and show how to handle homogeneous chemical reactions, even including coupled and nonlinear cases. On this basis, more advanced techniques are briefly sketched and some of the commercially available programs are discussed. In this way the reader is systematically guided and can learn the tools for approaching his own electrochemical simulation problems. This new fourth edition has been carefully revised, updated and extended compared to the previous edition (Lecture Notes in Physics Vol. 666). It contains new material describing migration effects, as well as arrays of ultramicroelectrodes. It is thus the most comprehensive and didactic introduction to the topic of electrochemical simulation.

This book was released on 2013-03-14 with total page 235 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is an extensive revision of the earlier book with the same title, 1981. The reader who has the first edition will recognise chapters 1-3 and parts of Chapt. 4; thereafter, there is little similarity. There are several reasons for this. Firstly, as one internal Danish publication stated, the first edition contained "et hav af smafejl" meaning (with some poetic license), a sea of troubles. I welcomed the opportunity of setting this right. Secondly, a number of readers rightly criticised my glib dismissal of problems connected with homogeneous chemical reactions in the first edition, now dealt with. Thirdly, digital simulation has not stood still since 1980 and this book reflects the newer developments such as orthogonal collocation, algorithms for the implicit boundary value calculations, as well as my own recent findings. Despite all this activity, no text has appeared to displace that of Feldberg (1969) or my first edition of 1981. My aim is to explain the subject clearly and simply. The electrochemist (or student) who occasionally needs to simulate a diffusion problem numerically but does not wish to go in for sophisticated methods, can make do with the first four chapters. Desk time is then traded for computer time. If this becomes excessive and/or the simulator's interest in more efficient techniques is aroused, Chapt. 5 provides an introduction. The easiest of these is the Runge-Kutta integration method, providing a modest but definite gain in efficiency at very small cost in terms of desk time.
Download or read book Digital Simulation in Electrochemistry written by D. Britz and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 131 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book is the result of frustration. When I first became interested in digi tal simulation in 1967 (I didn't know the name then), there were no texts to tell one the how of it. This has not changed greatly since then; it is significant that just about all publications about the technique refer to a chapter by Feldberg in an electrochemical series, written in 1969. When I ran a course on the method recently, it became evident that this chapter is not enough for the raw beginner. Neither does he/she get much help from the mathematical textbooks which, at best, leave the special electrochemical aspects (if not a lot else) to one's imagination. This book, then, is written for practical digital simulators who do not have a friend who will tell them how to do it. The beauty of the digital approach is that one can separate out various dynamic processes taking place simultaneously. I have structured the book in this way. The major computing usually lies in the diffusion of substance, while the major program ming effort (and preparatory paper work) goes into the boundary conditions. These are treated separately.

Download or read book Aptamers in Biotechnology written by Katharina Urmann and published by Springer Nature. This book was released on 2020-07-31 with total page 217 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book reviews the development, characterization and applications of aptamers in different areas of biotechnology ranging from therapeutics to diagnostics and protein purification. Hailed as chemical antibodies, these single-stranded nucleic acid receptors were predicted to supersede antibodies in traditional assays, such as ELISA, within a short time. While this has yet to happen, readers will find in this book a deep insight into the progress of aptamer technology and a critical discussion about the limitations that need to be overcome in order to find wider acceptance and use outside of the still relatively small aptamer-community. This book covers all aspects of aptamer generation and application for the aptamer-experienced reader and curious novice alike, with the addition of an industry perspective on the future of aptamer-use in biotechnology.
