They worked hard, these men in secret places, their aim and object the conquest of space. Obstacles were many, not the least among them being a shortage of financial backing. But at last a day came when a guided projectile was launched on its journey into space. Only then did the worst snag of all become apparent...This is a very scarce, highly sought classic sci-fi novel!

Cellophane, a gel developed from crystalline alphacellulose, has been used as an ionic barrier (battery separator) in electrical batteries with outstanding success for many years. Understanding the mechanism of the cellophane action in ionic barrier applications could lead to the development of superior ionic barriers. A literature survey has been conducted on the characteristics of cellophane as related to electrochemical cell barrier applications. The physical or chemical bonding of ions in electrolyte solutions to molecules in the membrane, or the catalytic complexing of undesirable ions appear to be much more important in the effective operation of cellophane as a barrier than the filtering or capillary diffusion actions, although these latter actions cannot be ignored.

The blocking of ion transport at interfaces strongly limits the performance of electrochemical nanodevices for energy applications. The barrier is believed to arise from space-charge regions generated by mobile ions by analogy to semiconductor junctions. Here we show that something different is at play by studying ion transport in a bicrystal of yttria (9% mol) stabilized zirconia (YSZ), an emblematic oxide ion conductor. Aberration-corrected scanning transmission electron microscopy (STEM) provides structure and composition at atomic resolution, with the sensitivity to directly reveal the oxygen ion profile. We find that Y segregates to the grain boundary at Zr sites, together with a depletion of oxygen that is confined to a small length scale of around 0.5 nm. Contrary to the main thesis of the space-charge model, there exists no evidence of a long-range O vacancy depletion layer. Combining ion transport measurements across a single grain boundary by nanoscale electrochemical strain microscopy (ESM), broadband dielectric spectroscopy measurements, and density functional calculations, we show that grain-boundary-induced electronic states act as acceptors, resulting in a negatively charged core. In conclusion, besides the possible effect of the modified chemical bonding, this negative charge gives rise to an additional barrier for ion transport at the grain boundary.

Abstract: The electrical and mechanical characteristics of the wire-to-plate surface dielectric barrier discharge and the induced ionic wind are investigated experimentally. The different temporal behaviors in positive and negative half-cycles are studied by time-resolved images. It is shown that the discharge and the light emission are generally stronger in the positive half cycle. The discharge is inhomogeneous and propagates in streamer mode; however, in the negative half-cycle, the discharge appears visually uniformly and operates in the diffuse mode. The surface discharge can produce ionic wind about several m/s above the dielectric surface. There exists an optimal width of the grounded electrode to produce a larger plasma area or active wind region. Increasing of the applied voltage or normalized dielectric constant leads to a larger wind velocity. The performance of ionic wind on flow control is visualized by employing a smoke stream.

This thesis presents the first direct observations of the 3D-shape, size and electrical properties of nanoscale filaments, made possible by a new Scanning Probe Microscopy-based tomography technique referred to as scalpel SPM. Using this innovative technology and nm-scale observations, the author achieves essential insights into the filament formation mechanisms, improves the understanding required for device optimization, and experimentally observes phenomena that had previously been only theoretically proposed.

Discover the physical chemistry of charge carriers in the second edition of this popular textbook Ionic and electronic charge carriers are critical to the kinetic and electrochemical properties of ionic solids. These charge carriers are point defects and are decisive for electrical conductivity, mass transport, and storage phenomena. Generally, defects are deviations from the perfect structure, and if higher-dimensional, also crucial for the mechanical properties. The study of materials science and energy research therefore requires a thorough understanding of defects, in particular the charged point defects, their mobilities, and formation mechanisms. Physical Chemistry of Ionic Materials is a comprehensive introduction to these charge carrier particles and the processes that produce, move, and activate them. Covering both core principles and practical applications, it discusses subjects ranging from chemical bonding and thermodynamics to solid-state kinetics and electrochemical techniques. Now in an updated edition with numerous added features, it promises to be the essential textbook on this subject for a new generation of materials scientists. Readers of the 2nd Edition of Physical Chemistry of Ionic Materials will also find: Two new chapters on solid state electrochemistry and another on nanoionics Novel brief sections on photoelectrochemistry, bioelectrochemistry, and atomistic modelling put the treatment into a broader context Discussion of the working principles required to understand electrochemical devices like sensors, batteries, and fuel cells Real laboratory measurements to ground basic principles in practical experimentation Physical Chemistry of Ionic Materials is a valuable reference for chemists, physicists, and any working researchers or advanced students in the materials sciences.

This book introduces ionic materials and nanocomposites which are one of the most viable materials for solid state energy storage devices. The basic concepts of ionic materials and nanocomposites, their properties, fundamental theories of ion conduction and different experimental methods employed to study such materials are included. The details are presented in a simple, logical and coherent manner. A lot of exercise questions are provided at the end of each chapter to test concept & learning. The distinct salient feature of the book is the inclusion of several project work assignments at the end of each chapter which is suitable for UG and PG level projects. Also, some advanced project assignments are added in the last chapter which would encourage advance thinking and research initiative in this area. This book would be thus highly suitable for upper UG, PG and beginner research students.
