Download or read book Promoting the reversibility of electrolytic MnO2 Zn battery with high areal capacity by VOSO4 mediator written by Yong Xu and published by OAE Publishing Inc.. This book was released on 2024-01-05 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: Electrolytic MnO2-Zn batteries possess high energy density due to the high reduction potential and capacity of the cathode Mn2+/MnO2. However, the low reversibility of the Mn2+/MnO2 conversion results in a limited lifespan. In this study, we propose the utilization of VOSO4 as a redox mediator in the MnO2-Zn battery to facilitate the dissolution of MnO2. Through various techniques such as electrochemical measurements, ex-situ UV-visible spectroscopy, X-ray diffraction, and scanning electron microscopes, we validate the interaction between VO2+ and MnO2, which effectively mitigates the accumulation of MnO2. The introduction of the redox mediator results in exceptional redox reversibility and outstanding cycling stability of the MnO2/VOSO4-Zn battery at high areal capacities, with 900 cycles at 5 mAh cm-2 and 500 cycles at 10 mAh cm-2. Notably, even in the flow battery device, the battery exhibits a stable cycling performance over 300 cycles at 20 mAh cm-2. These research findings shed light on the potential large-scale application of electrolytic MnO2-Zn batteries.

Download or read book Protein Nanoparticle Interactions written by Masoud Rahman and published by Springer Science & Business Media. This book was released on 2013-06-24 with total page 95 pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, the fabrication of nanomaterials and exploration of their properties have attracted the attention of various scientific disciplines such as biology, physics, chemistry, and engineering. Although nanoparticulate systems are of significant interest in various scientific and technological areas, there is little known about the safety of these nanoscale objects. It has now been established that the surfaces of nanoparticles are immediately covered by biomolecules (e.g. proteins, ions, and enzymes) upon their entrance into a biological medium. This interaction with the biological medium modulates the surface of the nanoparticles, conferring a “biological identity” to their surfaces (referred to as a “corona”), which determines the subsequent cellular/tissue responses. The new interface between the nanoparticles and the biological medium/proteins, called “bio-nano interface,” has been very rarely studied in detail to date, though the interest in this topic is rapidly growing. In this book, the importance of the physiochemical characteristics of nanoparticles for the properties of the protein corona is discussed in detail, followed by comprehensive descriptions of the methods for assessing the protein-nanoparticle interactions. The advantages and limitations of available corona evaluation methods (e.g. spectroscopy methods, mass spectrometry, nuclear magnetic resonance, electron microscopy, X-ray crystallography, and differential centrifugal sedimentation) are examined in detail, followed by a discussion of the possibilities for enhancing the current methods and a call for new techniques. Moreover, the advantages and disadvantages of protein-nanoparticle interaction phenomena are explored and discussed, with a focus on the biological impacts.

Download or read book Supercapacitors written by Francois Beguin and published by John Wiley & Sons. This book was released on 2013-04-02 with total page 596 pages. Available in PDF, EPUB and Kindle. Book excerpt: Supercapacitors are a relatively new energy storage system that provides higher energy density than dielectric capacitors and higher power density than batteries. They are particularly suited to applications that require energy pulses during short periods of time, e.g., seconds or tens of seconds. They are recommended for automobiles, tramways, buses, cranes, fork-lifts, wind turbines, electricity load leveling in stationary and transportation systems, etc. Despite the technological maturity of supercapacitors, there is a lack of comprehensive literature on the topic. Many high performance materials have been developed and new scientific concepts have been introduced. Taking into account the commercial interest in these systems and the new scientific and technological developments now is the ideal time to publish this book, capturing all this new knowledge. The book starts by giving an introduction to the general principles of electrochemistry, the properties of electrochemical capacitors, and electrochemical characterization techniques. Electrical double layer capacitors and pseudocapacitors are then discussed, followed by the various electrolyte systems. Modelling, manufacture of industrial capacitors, constraints, testing, and reliability as well as applications are also covered. 'Supercapacitors - Materials, Systems, and Applications' is part of the series on Materials for Sustainable Energy and Development edited by Prof. G.Q. Max Lu. The series covers advances in materials science and innovation for renewable energy, clean use of fossil energy, and greenhouse gas mitigation and associated environmental technologies.

Download or read book Macroeconomics written by David Miles and published by John Wiley & Sons. This book was released on 2012-04-09 with total page 626 pages. Available in PDF, EPUB and Kindle. Book excerpt: Macroeconomics: Understanding the Global Economy, 3rd Edition is to help students – and indeed anyone – understand contemporary and past economic events that shape the world we live in, and at a sophisticated level. But it does so without focusing on mathematical techniques and models for their own sake. Theory is taken seriously – so much so that the authors go to pains to understand the key aspects of theories in a way that will not put people off before they see how theories are useful to analyse issues. The authors believe that theories are essential to better understand the world, thus the book includes a wealth of historic and current episodes and data to both see how theories can help interpret the world and also to judge their validity. Economies today are very inter-connected; what happens in China matters pretty much everywhere; and what happens in one (even small) country in the euro zone has implications for the whole euro area and beyond, consequently Macroeconomics, 3rd Edition adopts a very international focus.
