"This book came about because of my poor memory: it is amazing how quickly and easily an experienced electron microscopist/mineralogist can identify minerals with an Energy Dispersive Spectrometer (EDS). It is also amazing how long it takes someone who is not good at mineralogy to search through a mineralogy text, trying to match the peaks on their unknown spectrum with the chemical formula of some mineral. After the mineral is finally identified, it is easy to identify other specimens of similar composition as EDS spectra have very distinctive patterns. For me, however, as I move between...

Design of new molecular materials is emerging as a new interdisciplinary research field. Corresponding reports are scattered in literature, and this book constitutes one of the first attempts to overview ongoing research efforts. It provides basic information, as well as the details of theory and examples of its application, to experimentalists and theoreticians interested in modeling molecular properties and putting into practice rational design of new materials.

This book brings together the work of leading chemistry educators who are researching the triplet relationship at secondary and university levels. It discusses the learning involved, the problems that students encounter, and successful approaches to teaching.

For centuries man has treated food to prolong its edible life, and nowadays both traditional and modern preservatives are used widely to ensure the satisfactory maintenance of quality and safety of foods. There continues to be increased public concern about the use of food additives, including preservatives, resulting from a perception that some of them may have deleterious effects on health. However, as eating habits have changed with an emphasis on what has been popularly termed a healthy diet', there is at the same time a concern that reduction in preservative usage could lead to loss...
