This comprehensive, truly one-stop reference discusses monomers, methods, stereochemistry, industrial applications and more. Chapters written by internationally acclaimed experts in their respective fields cover both basic principles and up-to-date information, ranging from the controlled ring-opening polymerization methods to polymer materials of industrial interest. All main classes of monomers including heterocyclics, cyclic olefins and alkynes, and cycloalkanes, are discussed separately as well as their specificities regarding the ring-opening polymerization techniques, the mechanisms, the degree of control, the properties of the related polymers and their applications. The two last chapters are devoted to the implementation of green chemistry in ring-opening polymerization processes.
Of much interest to chemists in academia and industry.

How can single atoms be manipulated? Are the laws of physics still valid at the nanostructure scale? How could nanotechnologies help cure disease? What are the application fields of nanotechnologies and what ethical issues do they raise? These questions and many others are answered in this clearly presented, fascinating book. This updated second edition puts nanotechnologies into perspective by explaining issues in health, environmental and military application domains, and discusses the technology in the context of current media and ethical debates. It also introduces the ambitious, and perhaps almost utopian, NBIC programme (Nanotechnology, Biotechnology, Information technology and Cognitive science) - an initiative that foresees the 'reunification' of science by encouraging collaboration among specialists of different scientific domains. Intended for a wide audience, this book will interest teachers and students of science, as well as those with a general interest in how modern technologies and the sciences interact.

Si hay en la fotografa una fuerza invisible, si en ella existe algo atribuible al orden de la gravedad absoluta -y es precisamente en lo que este libro quisiera insistir-, es exactamente esto, que en la fotografa no podemos pensar en la imagen aislada, desmembrada del acto que la ha hecho surgir. La fotografa no es slo una imagen (el producto de una tcnica y de una accin, el resultado de un hacer y de un saber hacer, una imagen de papel que se mira sencillamente en su soporte de objeto terminado), es tambin, y de modo especial, un verdadero acto icnico, una imagen si se prefiere, pero trabajando, algo que no se puedeconcebir sin sus circunstancias, sin el juego que la anima, sin haber hecho literalmente la prueba: algo que es a la vez y consustancialmente una imagen acto, dejando bien asentado que ese "actoLa fotografa, en definitiva, como inseparable de todo su enunciado, como experiencia de imagen, como objeto totalmente pragmtico. De aqu se deduce hasta qu punto este medio mecnico, ptico- qumico, supuestamente objetivo, del que a veces se ha dicho en el plano filosfico que se efecta sin el concurso humano, implica ontolgicamente la cuestin del sujeto, y ms concretamente del sujeto en accin.
