• Sommario/riassunto: Although synthetic fullerenes have only been around for a few years, there are thousands of scientific articles dealing with them. This is the first monograph in the field and thus represents a vital source of information summarizing the most important and fundamental aspects of the organic and organometallic chemistry of the fullerenes. The book is logically arranged so that information is easy to retrieve, and the style lends itself to effortless reading and to learning more about the chemical properties of a family of molecules that constitute new building blocks for novel architectures

• Sommario/riassunto: Im Kontext partizipativer Filmprojekte für fluchterfahrene Jugendliche wird Sichtbarkeit oft mit Ermächtigung gleichgesetzt. Gerhard Schönhofer hinterfragt diese Logik, indem er Prozesse des Sichtbarmachens, wie sie in Workshop-Formaten geschehen, ethnografisch beschreibt. Durch die Nähe zum Forschungsfeld wird somit nicht nur ein präzises Bild des Selbstverständnisses, sondern auch der Anspruchshaltungen der Projektleitenden gezeichnet, die bisweilen im Spannungsfeld zu den Motivationen der teilnehmenden Jugendlichen stehen.
