En los ultimos anos ha habido un interes creciente en el estudio de las nanoparticulas metalicas (tamano entre 1-20 nm) en diferentes campos de la ciencia e industria. Este interes se debe a que estas particulas presentan propiedades fisicoquimicas distintas a aquellas que presentan el material masico y a las propiedades de los atomos. Mas aun, con la adicion de otro metal, se obtiene un material con nuevas e interesantes propiedades. En este sentido, este libro muestra una via de sintesis de nanoparticulas de niquel y molibdeno soportadas sobre carbon, hexadecilamina (HDA), silice y alumina,...

Machines have always gone hand-in-hand with the cultural development of m- kind throughout time. A book on the history of machines is nothing more than a specific way of bringing light to human events as a whole in order to highlight some significant milestones in the progress of knowledge by a complementary persp- tive into a general historical overview. This book is the result of common efforts and interests by several scholars, teachers, and students on subjects that are connected with the theory of machines and mechanisms. In fact, in this book there is a certain teaching aim in addition...
