“…If the boundary is not static, the analysis of the growth of a precipitate is much more complicated. Glicksmann evaluated the movingboundary problem of 3D precipitate growth in relation to the static-boundary case [22], and found that for small supersaturations the difference is negligible. A similar analysis has been done by Aaron and coworkers in the context of diffusional phase transformations [23].…”

The facile conduction of alkali ions in a crystal host is of crucial importance in rechargeable alkali-ion batteries, the dominant form of energy storage today. In this review, we provide a comprehensive survey of computational approaches to study solid-state alkali diffusion. We demonstrate how these methods have provided useful insights into the design of materials that form the main components of a rechargeable alkali-ion battery, namely the electrodes, superionic conductor solid electrolytes and interfaces. We will also provide a perspective on future challenges and directions. The scope of this review includes the monovalent lithium-and sodium-ion chemistries that are currently of the most commercial interest. NPG Asia Materials (2016) 8, e254; doi:10.1038/am.2016.7; published online 25 March 2016 INTRODUCTIONThe facile conduction of alkali ions in a crystal is of critical importance in energy storage. Today, the dominant form of energy storage in consumer electronics is the rechargeable lithium-ion (Li-ion) battery, 1-5 a device that functions entirely on the basis of the reversible transport of Li + ions. With one of the highest energy densities of known energy storage technologies, Li-ion batteries are finding increasingly large-scale applications in electrified transportation and grid storage. In recent years, there has also been a resurgence of interest in rechargeable sodium-ion (Na-ion) batteries, 6-12 which function on the same basic principle but with Na + instead of Li + because of concerns regarding the abundance and cost of lithium. Figure 1 shows a representation of a rechargeable alkali-ion battery. The typical electrode in an alkali-ion battery is an intercalation compound, which, as the name implies, stores alkali ions by inserting them into its crystal structure in a topotactic manner. During discharge, A + ions are transported from the anode, through the electrolyte and into the cathode. The reverse happens during charge. Throughout this review, we will adopt the customary terminology of defining the 'cathode' as the positive electrode during discharge, even though the formal definition of the cathode changes depending on whether the charging or discharging process is being referred to. Current cathodes are typically transition metal oxides, and the insertion/removal of each A + in the cathode is accompanied by the concomitant reduction/oxidation of a transition metal ion to accommodate the compensating insertion/removal of an electron. Graphitic carbon is the most common anode.The performance of a rechargeable alkali-ion battery depends crucially on the ease with which alkali ions move in the host crystal of the cathode and anode, in the electrolyte, and in the electrodeelectrolyte interface. Poor alkali transport in any part of the battery

Plasma can be broadly defined as a state of matter in which a significant number of the atoms and/or molecules are electrically charged or ionized, but the numbers of charges, both negative and positive, are equal. Plasma technology involves the use of these natural or artificially produced plasmas, whether gases, solid, or liquid. Plasmas range in size and density from wisps of interstellar matter to those that exist within the solids used in solid‐state technologies to those that are the unimaginably dense and hot interiors of stars. Plasmas can be as natural as lightning or the aurora borealis, or artificially produced, such as the flashes resulting from thermonuclear fusion experiments. Production of plasmas, modification and possible dissipation, as well as the diagnostics for examining plasmas of various types are included. Differences between gaseous plasmas and plasmas in condensed matter are examined. Uses of plasma include radiation sources, plasma chemistry, chemical analysis, plasma processing, surface modification, plasma polymerization, materials production, energy production, guns and missiles, explosives, weapons, communications, and space travel. Ongoing research in several areas points to a bright future for plasma technology.
