Immaginiamo un futuro in cui sapiens supertecnologici controlleranno, con le loro intelligenze aumentate, il mondo, mentre altri sapiens desueti, saranno relegati a un ruolo marginale. Uno scenario solo fantascientifico? Oggi l'intelligenza artificiale, le neuroscienze, le nanotecnologie, la genetica modificano in modo sempre più vertiginoso il rapporto tra l'uomo e la natura. Nella storia dell'umanità sta succedendo qualcosa che potrebbe anch...

This is a critical assessment of policies and behaviour in science production and publication, touching upon the tumultuous growth of scientific journals in parallel with the growth of self-declared scientists worldwide. The author investigates these problems of science and how this can seriously affect the relationship between science and society.

Negli ultimi anni il modo di fare scienza è radicalmente cambiato. Le riflessioni e le esperienze personali di un protagonista ci aiutano a capire i meccanismi della ricerca scientifica contemporanea. Un sistema in cui passione e rigore faticano a trovare spazio, schiacciati come sono da dure leggi di mercato. Da vocazione di pochi, fare ricerca è diventato un mestiere di molti, forse di troppi. Con conseguenze e rischi, come l'aumento di frod...

It is widely recognized that an understanding of the physical and chemical properties of clusters will give a great deal of important information relevant to surface and bulk properties of condensed matter. This relevance of clusters for condensed matter is one of the major motivations for the study of atomic and molecular clusters. The changes of properties with cluster size, from small clusters containing only a few atoms to large clusters c...

Heterogeneous catalysis provides the backbone of the world's chemical and oil industries. The innate complexity of practical catalytic systems suggests that useful progress should be achievable by investigating key aspects of catalysis by experimental studies on idealised model systems. Thin films and supported clusters are two promising types of model system that can be used for this purpose, since they mimic important aspects of the properti...

La storia di una rivoluzione scientifica e culturale, dalle intuizioni di Richard Feynman e Primo Levi alle scoperte che hanno consentito di "vedere" gli atomi e di manipolarli individualmente. E poi le applicazioni, che sono già realtà: usiamo nanoparticelle nelle marmitte catalitiche, nei farmaci, perfino nei cosmetici, e si lavora a nanostrutture per l'elettronica "di plastica", la produzione di energia, la diagnostica medica. Le nanotecnol...

Silicon dioxide plays a central role in most contemporary electronic and photonic technologies, from fiber optics for communications and medical applications to metal-oxide-semiconductor devices. Many of these applications directly involve point defects, which can either be introduced during the manufacturing process or by exposure to ionizing radiation. They can also be deliberately created to exploit new technologies. This book provides a ...
