This edited book, based on material presented at the EU Spec Training School on Multiple Scattering Codes and the following MSNano Conference, is divided into two distinct parts. The first part, subtitled "basic knowledge", provides the basics of the multiple scattering description in spectroscopies, enabling readers to understand the physics behind the various multiple scattering codes available for modelling spectroscopies. The second part, "extended knowledge", presents "state- of-the-art" short chapters on specific subjects associated with improving of the actual description of spectroscopies within the multiple scattering formalism, such as inelastic processes, or precise examples of modelling.
PMCommon methods of local magnetic imaging display either a high spatial resolution and relatively poor field sensitivity (MFM, Lorentz microscopy), or a relatively high field sensitivity but limited spatial resolution (scanning SQUID microscopy). Since the magnetic field of a nanoparticle or nanostructure decays rapidly with distance from the structure, the achievable spatial resolution is ultimately limited by the probe-sample separation. This thesis presents a novel method for fabricating the smallest superconducting quantum interference device (SQUID) that resides on the apex of a very sharp tip. The nanoSQUID-on-tip displays a characteristic size down to 100 nm and a field sensitivity of 10 -3 Gauss/Hz (1/2). A scanning SQUID microsope was constructed by gluing the nanoSQUID-on-tip?? to a quartz tuning-fork. This enabled the nanoSQUID to be scanned within nanometers of the sample surface, providing simultaneous images of sample topography and the magnetic field distribution. This microscope represents a significant improvement over the existing scanning SQUID techniques and is expected to be able to image the spin of a single electro

Glow discharge optical emission spectroscopy (GDOES) is an essential technique for the direct analysis of bulk solids, for elemental surface analysis and for the depth profiling of thin films and industrial coatings. The technique has shown rapid growth in numbers of instruments, in breadth of applications, in improved quantification in recent years and is now a recognised technique within the ISO, with two international standards. Glow Discharge Optical Emission Spectroscopy: A Practical Guide takes the reader on a journey through instrument operation, sample preparation, analysis, and reporting results. It follows two sets of samples through the whole process of analysis, brass samples for bulk analysis, and zinc-coated steel for depth profiling. Procedures are consistent with recent ISO standards and each step is loaded with hands-on tips and theoretical insight. The book also includes unique data tables on spectral interferences, molecular bands, self-absorption and relative sputtering rates. This book is designed for those using or managing GDOES instruments and for students interested in learning the technique from a hands-on perspective. It is also an invaluable aid to those considering the purchase of a GDOES instrument, or those using GDOES results, to understand in detail how the technique works and what is involved in maintaining the instrument and achieving high quality results.

Spectroscopic data undoubtedly provides a great deal of useful information about organic molecules. Competently deriving structural information from such data therefore, is a requisite skill for many undergraduates studying chemistry. Interpreting Organic Spectra covers the basic principles of spectroscopy in as non-mathematical a way as possible. It assumes no previous knowledge of spectroscopy and avoids excessive theory, approaching the topic as an exercise in pattern recognition. Hence the main focus of the book is in the provision of a variety of spectra for the student to interpret. Students are able to pace their progress by gaining confidence on the simpler spectra, and applying techniques learned to tackle more complex examples. As an introduction to the subject, it is ideal for A-level students as well as chemistry undergraduates and will prove to be a very useful reference tool for teachers and lecturers.
