This book presents mechanics miniaturization trends explored step by step, starting with the example of the miniaturization of a mechanical calculator. The ultra-miniaturization of mechanical machinery is now approaching the atomic scale. In this book, molecule-gears, trains of molecule-gears, and molecule motors are studied -one molecule at a time- on a solid surface, using scanning probe manipulation protocols and in solution as demonstrated in the European project "MEMO". All scales of mechanical machinery are presented using the various lithography techniques currently available, from the submillimeter to the nanoscale. Researchers and nanomechanical engineers will find new inspirations for the construction of minute mechanical devices which can be used in diverse hostile environments, for example under radiation constraints, on the surface membrane of a living cell or immersed in liquid. The book is presented in a format accessible for university students, in particular for those at the Master and PhD levels.
Christian Joachim is the Director of Research at the Nanosciences Group in CEMES/CNRS, and an Adjunct Professor of Quantum Physics at ISAE Sup'Aero in Toulouse. In Singapore, he was A*STAR VIP at IMRE for atom technology and he now serves as the Head of the WPI MANA-NIMS satellite in Toulouse. He coordinated the integrated European projects "Bottom-up Nanomachines," "Pico-Inside" and "AtMol" (2011-2014), whose objective was to prepare the construct of the first ever molecular chip. He is the author of more than 300 scientific publications and has given over 400 invited talks on electron transfer through a molecule, STM and Atomic Force Microscopy (AFM) image calculations, tunnel transport through a molecule, molecular devices, nanolithography, and single-molecule machines.

Dateiformat: PDFKopierschutz: Wasserzeichen-DRM (Digital Rights Management)
Systemvoraussetzungen:
Das Dateiformat PDF zeigt auf jeder Hardware eine Buchseite stets identisch an. Daher ist eine PDF auch für ein komplexes Layout geeignet, wie es bei Lehr- und Fachbüchern verwendet wird (Bilder, Tabellen, Spalten, Fußnoten). Bei kleinen Displays von E-Readern oder Smartphones sind PDF leider eher nervig, weil zu viel Scrollen notwendig ist. Mit Wasserzeichen-DRM wird hier ein „weicher” Kopierschutz verwendet. Daher ist technisch zwar alles möglich – sogar eine unzulässige Weitergabe. Aber an sichtbaren und unsichtbaren Stellen wird der Käufer des E-Books als Wasserzeichen hinterlegt, sodass im Falle eines Missbrauchs die Spur zurückverfolgt werden kann.
