Meeting the demand for a readily understandable introduction to nanomaterials and nanotechnology, this textbook specifically addresses the needs of students – and engineers – who need to get the gist of nanoscale phenomena in materials without having to delve too deeply into the physical and chemical details. The book begins with an overview of the consequences of small particle size, such as the growing importance of surface effects, and covers successful, field-tested synthesis techniques of nanomaterials. The largest part of the book is devoted to the particular magnetic, optical, electrical and mechanical properties of materials at the nanoscale, leading on to emerging and already commercialized applications, such as nanofluids in magnetic resonance imaging, high-performance nanocomposites and carbon nanotube-based electronics. Based on the author's experience in teaching nanomaterials courses and adapted, in style and level, for students with only limited background knowledge, the textbook includes further reading, as well as information boxes that can be skipped upon first reading.

The first in-depth treatment of the synthesis, processing, and characterization of nanomaterials using lasers, ranging from fundamentals to the latest research results, this handy reference is divided into two main sections. After introducing the concepts of lasers, nanomaterials, nanoarchitectures and laser-material interactions in the first three chapters, the book goes on to discuss the synthesis of various nanomaterials in vacuum, gas and liquids. The second half discusses various nanomaterial characterization techniques involving lasers, from Raman and photoluminescence spectroscopies to light dynamic scattering, laser spectroscopy and such unusual techniques as laser photo acoustic, fluorescence correlation spectroscopy, ultrafast dynamics and laser-induced thermal pulses. The specialist authors adopt a practical approach throughout, with an emphasis on experiments, set-up, and results. Each chapter begins with an introduction and is uniform in covering the basic approaches, experimental setups, and dependencies of the particular method on different parameters, providing sufficient theory and modeling to understand the principles behind the techniques.

Nanowerkstoffe fur Einsteiger halt, was der Titel verspricht: Eine leichtverstandliche Einfuhrung zu Nanowerkstoffen fur alle, die sich mit den Grundlagen und dem Potential dieser vielseitigen Materialklasse vertraut machen mochten, ohne allzu tief in die physikalischen und chemischen Details einzusteigen. Nanowerkstoffe sind Materialien wie Metalle, Legierungen, Keramiken oder Polymere, in denen mindestens eine Langendimension kleiner als 100 Nanometer ist. In diesem Langenbereich zeigen diese Materialien ganz besondere und fein einstellbare optische, elektrische und mechanische Eigenschaften, die auf der makroskopischen Skala nicht zutage treten. Eine Vielzahl von Anwendungen an der Schnittstelle zwischen Materialwissenschaft, Chemie, Physik und Biologie ist bereits in kommerziell erhaltliche Produkte umgesetzt worden. Jedes Kapitel beginnt mit einer Einfuhrung in den Lernstoff «In diesem Kapitel» und endet mit einer Zusammenfassung «Wichtig zu wissen». In die Tiefe gehende Erklarungen sind in Boxen aufgenommen und konnen so leicht ausgelassen werden.
