Available in PDF, EPUB and Kindle. Book excerpt: Techniques and strategies for the production of nanomaterials and nanostructures have developed to an advanced level. However, the concepts and methods needed to correctly architect these materials into viable applications remains seriously lacking. This book introduces the concept of "Nanoarchitechtonics", a term introduced by Dr Masakazu Aono to describe the correct manipulation of nanoscale materials in the creation of nano-devices and applications. With contributions from across the globe, Manipulation of Nanoscale Materials presents a broad spectrum of nanomaterials and their applications. Following an introductory chapter prepared by the editors, the book is divided into three further sections of chapters, detailing Nanoarchitectonics for Materials Development, Materials Nanoarchitechtonics for Bio-Conjugates and Bio-Applications, Materials Nanoarchitechtonics for Advanced Devices. The first book in its field, this is essential reading for anyone creating or deploying nanomaterials. Fully referenced to the primary literature, this title presents an excellent source of information, and inspiration, to the reader and should appeal to experienced materials scientists, nanotechnologists and postgraduate students. Dr. Katsuhiko Ariga is the Director of Supermolecules Group and Principal Investigator of World Premier International (WPI) Research Center for Materials Nanoarchitectonics (MANA), the National Institute for Materials Science (NIMS). Dr Masakazu Aono is Director General of MANA and group leader of the nano-system organiszation group MANA, NIMS.
Download or read book Quantitative and Qualitative Results from Droplet Impingement Experiments on Superhydrophobic Surfaces with Micro ribs for Three Liquid Types written by John T. Pearson and published by . This book was released on 2010 with total page 103 pages. Available in PDF, EPUB and Kindle. Book excerpt: Experiments were performed in which liquid droplets were videographically recorded impacting horizontal superhydrophobic surfaces. The superhydrophobic surfaces were micropatterned with alternating ribs and cavities and coated with a hydrophobic coating. The following surface types were also tested for comparison: smooth uncoated, micropatterned uncoated, and smooth coated surfaces. Three liquid types were used: pure water, ethanol, and a 50/50 water/glycerine mixture. Acquired data demonstrated that the maximum droplet spread diameter exhibited a greater Weber number dependence than that previously reported in the literature. The time delays between impact and maximum spread and between impact and ejection of a vertical jet were characterized, and it was found that experiments with hydrophilic surface behavior follow somewhat different trends than those with hydrophobic behavior, and that there are modest differences between superhydrophobic and hydrophobic surfaces. When analyzing the velocity of the issuing vertical jet, a region of micro-jets was observed with velocities that, under certain conditions, can exceed 15 times the impact velocity. The experimental data acquired were also compared to two recent models from the literature and it was determined that the models do not adequately account for surface anisotropy or apparent slip at the solid-liquid interface. The experiments also showed that instabilities resulting in fingering are dependent upon surface and fluid type, but not contact angle. The onset of peripheral splashing was observed, in general, to occur at a lower Weber number as contact angle increased for the differing surfaces. For surfaces with rib and cavity features, the droplet spread and retraction were generally observed to be asymmetric with spread and retraction faster along the length of the ribs. The occurrence of two-pronged and oscillating jets for water/glycerine tests was also observed for all patterned surfaces. Lastly, an interesting spread pattern with four liquid droplets clustered at about 30° from the perpendicular direction was observed for all fluid types on patterned surfaces for high Weber numbers.

Download or read book Reactive Inkjet Printing written by Patrick J Smith and published by Royal Society of Chemistry. This book was released on 2017-11-27 with total page 284 pages. Available in PDF, EPUB and Kindle. Book excerpt: Reactive inkjet printing uses an inkjet printer to dispense one or more reactants onto a substrate to generate a physical or chemical reaction to form a product in situ. Thus, unlike traditional inkjet printing, the printed film chemistry differs to that of the initial ink droplets. The appeal of reactive inkjet printing as a chemical synthesis tool is linked to its ability to produce droplets whose size is both controllable and predictable, which means that the individual droplets can be thought of as building blocks where droplets can be added to the substrate in a high precision format to give good control and predictability over the chemical reaction. The book starts by introducing the concept of using reactive inkjet printing as a building block for making materials. Aspects such as the behaviour of printed droplets on substrate and their mixing is discussed in the first chapters. The following chapters then discuss different applications of the technique in areas including additive manufacturing and silk production, production of materials used in solar cells, printed electronics, dentistry and tissue engineering. Edited by two leading experts, Reactive Inkjet Printing: A Chemical Synthesis Tool provides a comprehensive overview of this technique and its use in fabricating functional materials for health and energy applications. The book will appeal to advanced level students in materials science.

Available in PDF, EPUB and Kindle. Book excerpt: International interest in nanoscience research has flourished in recent years, as it becomes an integral part in the development of future technologies. The diverse, interdisciplinary nature of nanoscience means effective communication between disciplines is pivotal in the successful utilization of the science. Nanochemistry: A Chemical Approach to Nanomaterials is the first textbook for teaching nanochemistry and adopts an interdisciplinary and comprehensive approach to the subject. It presents a basic chemical strategy for making nanomaterials and describes some of the principles of materials self-assembly over 'all' scales. It demonstrates how nanometre and micrometre scale building blocks (with a wide range of shapes, compositions and surface functionalities) can be coerced through chemistry to organize spontaneously into unprecedented structures, which can serve as tailored functional materials. Suggestions of new ways to tackle research problems and speculations on how to think about assembling the future of nanotechnology are given. Primarily designed for teaching, this book will appeal to graduate and advanced undergraduate students. It is well illustrated with graphical representations of the structure and form of nanomaterials and contains problem sets as well as other pedagogical features such as further reading, case studies and a comprehensive bibliography.
