Behind the appearance of an innovative vaccine there is a history of determination and struggle, of breaking established models, and of overcoming the mistrust that generates a new theory. In this book we are going to learn about those stories, the stories of great scientists who fought to prove new theories and are now behind vaccines that save or will save millions of lives. We will experience with them the moment when they discovered that they had defeated a virus. We will travel inside the infectious agents to learn about their ability to gain ground in humans, the biological tools they...

Biographies and bibliographies of members are included in many of the volumes. Lists of members are usually given on covers of the numbers.

In previous volumes in this series, Advances in Metal and Semiconductor Clusters, the focus has been on atomic clusters of metals, semiconductors and carbon. Fundamental gas phase studies have been surveyed, and most recently scientists have explored new materials which can be produced from clusters or cluster precursors. In this latest volume, the focus shifts to clusters composed primarily of non-metal molecules or atoms which have one or more metal atoms seeded into the cluster as an impurity. These clusters provide model systems for metal ion solvation processes and metal-ligand...
