Informationen zum Autor Faraday Discussions documents a long-established series of Faraday Discussion meetings which provide a unique international forum for the exchange of views and newly acquired results in developing areas of physical chemistry, biophysical chemistry and chemical physics. The papers presented are published in the Faraday Discussion volume together with a record of the discussion contributions made at the meeting. Faraday Discussions therefore provide an important record of current international knowledge and views in the field concerned. The latest (2012) impact factor of Faraday Discussions is 3.82. Klappentext Faraday Discussions 134 This volume focuses on the recent advances in atomic transport in solids, one of the central themes in contemporary solid state science. This exciting research is driven by scientific problems and the technological need for improved materials such as lithium batteries, fuel cells, catalysts and sensors. Work is presented in the following areas: Fundamentals: transport mechanisms; defect processes; structure-property relationships; nanoscale and interface effects; Materials and applications: oxide-ion and proton conductors for fuel cells, sensors and membranes; nanostructured materials; polymer electrolytes and lithium battery electrodes; metals/ alloys; minerals; Techniques: microscopy; diffraction; spectroscopy (e.g. NMR); electrochemical; computer modelling (atomistic and quantum mechanical). Zusammenfassung Atomic transport in solids is one of the central themes in contemporary solid state science. In this book a wide variety of topics are covered and perspectives from different inter-related areas are provided.
