Описание: This book has evolved from a course on Mechanics of Robots that the author has thought for over a dozen years at the University of Cassino at Cassino, Italy.
Описание: This Springer Laboratory volume is a practical guide for scientists and students dealing with the measurement of mechanical properties of polymers at the nanoscale through AFM force-distance curves.In the first part of the book the reader will find a theoretical introduction about atomic force microscopy, focused on force-distance curves, and mechanical properties of polymers. The discussion of several practical issues concerning the acquisition and the interpretation of force-distance curves will help scientists starting to employ this technique.The second part of the book deals with the practical measurement of mechanical properties of polymers by means of AFM force-distance curves. Several 'hands-on' examples are illustrated in a very detailed manner, with particular attention to the sample preparation, data analysis, and typical artefacts. This section gives a complete overview about the qualitative characterization and quantitative determination of the mechanical properties of homogeneous polymer samples, polymer brushes, polymer thin films, confined polymer samples, model blends and microstructured polymer blends through AFM force-distance curves. The book also introduces to new approaches and measurement techniques, like creep compliance and force modulation measurements, pointing out approximations, limitations and issues requiring further confirmation.
Описание: This thesis addresses elementary dislocation processes occurring in single-crystalline alloys based on Fe-Al, and investigates correspondences between dislocation distribution inside crystals characterized by transmission electron microscopy (TEM) and surface patterns observed using atomic force microscopy (AFM). Fe-Al alloys with different degrees of ordering were prepared and deformed in compression at ambient temperature in-situ inside the AFM device. The evolution of slip line structures was captured in the sequences of AFM images and wavy slip bands, while cross slip at the tip of the slip band and homogeneous fine slip lines were also identified. Further, the thesis develops a technique for constructing 3D representations of dislocations observed by TEM without the prohibitive difficulties of tomography, and creates 3D models of dislocation structures. Generally speaking, the thesis finds good agreement between AFM and TEM observations, confirming the value of AFM as a relevant tool for studying dislocations.
Описание: Still valid and useful after a decade, this work presents critical reviews of the present position and future trends in modern chemical research. It contains short and concise reports on chemistry, each written by world-renowned experts.
