There is a major lack of fundamental knowledge and understanding on the interaction between a filler and the polymer matrix. When it comes to nanoscale fillers, such as layered silicates, carbon nanotubes, graphene or cellulose nanofibers it is even more important to know accurate structure-property relationships as well as identifying the parameters influencing material behavior. The reason for the lack of knowledge on how to process nanocomposites and why there are so few applications is that several scientific fields are affected and a joint effort of those scientific communities involved is necessary - starting from the filler manufacturing or pre-processing over polymer chemistry to the polymer processing. Within this book for the first time all involved scientific areas are viewed together providing an all-embracing coverage of all stages of polymer clay nanocomposites processing from lab scale to large scale / industry scale - stages from the raw material over manufacturing of polymer clay nanocomposites to characterization and the final products. The reader of the book will gain insight in the
physical/chemical pre-processing of layered silicates and their
incorporation into a polymer matrix using sophisticated
technologies (such as advanced compounding) as well as in real-time
quality control of the nanocomposite production and future
prospects. Finally nanotoxicological and nanosafety aspects will
complete the book.
Multiferroics, materials with a coexistence of magnetic and ferroelectric order, provide an efficient route for the control of magnetism by electric fields. The authors cover multiferroic thin-film heterostructures, device architectures and domain/interface effects. They critically discuss achievements as well as limitations and assess opportunities for future applications.
"Damage on Pumps and Systems. The Handbook for the Operation of Centrifugal Pumps" offers a combination of the theoretical basics and practical experience for the operation of circulation pumps in the engineering industry. Centrifugal pumps and systems are extremely vulnerable to damage
from a variety of causes, but the resulting breakdown can be
prevented by ensuring that these pumps and systems are operated
properly. This book provides a total overview of operating
centrifugal pumps, including condition monitoring, preventive
maintenance, life cycle costs, energy savings and economic aspects.
Extra emphasis is given to the potential damage to these pumps and
systems, and what can be done to prevent breakdown.
Surface modification of magnesium and its alloys for biomedical applications: Biological interactions, mechanical properties and testing, the first of two volumes, is an essential guide on the use of magnesium as a degradable implant material. Due to their excellent biocompatibility and biodegradability, magnesium based degradable implants provide a viable option for the permanent metallic implants. This volume focuses on the fundamental concepts of surface modification of magnesium, its biological interactions, mechanical properties and, in vitro and in vivo testing. The contents of volume 1 is organized and presented in three parts. Part 1 reviews the fundamental aspects of surface modification of magnesium, including surface design, opportunities, challenges and its role in revolutionizing biodegradable biomaterials. Part 2 addresses the biological and mechanical properties covering an in vivo approach to the bioabsorbable behavior of magnesium alloys, mechanical integrity and, the effects of amino acids and proteins on the performance of surface modified magnesium. Part 3 delves in to testing and characterization, exploring the biocompatibility and effects on fatigue life alongside the primary characteristics of surface modified magnesium. All chapters are written by experts, this two volume series provides systematic and thorough coverage of all major modification technologies and coating types of magnesium and its alloys for biomedical applications.
Many physical properties of our universe, such as the relative strength of the fundamental interactions, the value of the cosmological constant, etc., appear to be fine-tuned for existence of human life. One possible explanation of this fine tuning assumes existence of a multiverse, which consists of a very large number of individual universes having different physical properties. Intelligent observers populate only a small subset of these universes, which are fine-tuned for life. In this book we will review several interesting metamaterial systems, which capture many features of important cosmological models and offer insights into the physics of many other non-trivial spacetime geometries, such as microscopic black holes, closed time-like curves (CTCs) and the Alcubierre warp drive.
Volume 7 & 8
This book describes the fundamentals and potential applications
of friction stir superplasticity for unitized structures .
Conventional superplastic forming of sheets is limited to the
thickness of 3 mm because the fine grained starting material is
produced by rolling. Friction stir superplasticity has grown
rapidly in the last decade because of the effectiveness of
microstructural refinement. The thickness of the material remains
almost constant, and that allows for forming of thick
sheets/plates, which was not possible before. The field has reached
a point where designers have opportunities to expand the extent of
unitized structures, which are structures in which the traditional
primary part and any supporting structures are fabricated as a
single unit. With advanced optimization and material
considerations, this class of structures can be lighter weight and
more efficient, making them less costly, as well as mechanically
less complex, reducing areas of possible failure.
Open microfluidics, the study of microflows having a boundary with surrounding air, encompasses different aspects such as paper or thread-based microfluidics, droplet microfluidics and open-channel microfluidics. Open-channel microflow is a flow at the micro-scale, guided by solid structures, and having at least a free boundary (with air or vapor) other than the advancing meniscus. This book is devoted to the study of open-channel microfluidics which (contrary to paper or thread or droplet microfluidics) is still very sparsely documented, but bears many new applications in biology, biotechnology, medicine, material and space sciences. Capillarity being the principal force triggering an open microflow, the principles of capillarity are first recalled. The onset of open-channel microflow is next analyzed and the fundamental notion of generalized Cassie angle (the apparent contact angle which accounts for the presence of air) is presented. The theory of the dynamics of open-channel microflows is then developed, using the notion of averaged friction length which accounts for the presence of air along the boundaries of the flow domain. Different channel morphologies are studied and geometrical features such as valves and capillary pumps are examined. An introduction to two-phase open-channel microflows is also presented showing that immiscible plugs can be transported by an open-channel flow. Finally, a selection of interesting applications in the domains of space, materials, medicine and biology is presented, showing the potentialities of open-channel microfluidics.
Silicon technology is evolving rapidly, particularly in
board-to-board or chip-to chip applications. Increasingly, the
electronic parts of silicon technology will carry out the data
processing, while the photonic parts take care of the data
communication. For the first time, this book describes the merging
of photonics and electronics in silicon and other group IV
elements. It presents the challenges, the limitations, and the
upcoming possibilities of these developments. The book describes
the evolution of CMOS integrated electronics, status and
development, and the fundamentals of silicon photonics, including
the reasons for its rapid expansion, its possibilities and
limitations. It discusses the applications of these technologies
for such applications as memory, digital logic operations, light
sources, including drive electronics, optical modulators,
detectors, and post detector circuitry. It will appeal to engineers
in the fields of both electronics and photonics who need to learn
more about the basics of the other field and the prospects for the
integration of the two. Describes the evolution of CMOS integrated electronics, status and development, and the fundamentals of silicon photonics
"Nanomaterials in the Environment" covers all aspects of manufactured nanomaterials and their impact and behavior in the environment. Starting with a general overview of the field, emphasizing key points and background, the book then covers crucial specific areas, including nanomaterial transformations in the environment due to dissolution, aggregation, and other processes, and the modeling of environmental exposure and fate. A chapter on formation of the eco-corona investigates the state of the art with specific reference to the protein corona literature in human health. Finally, there are chapters on mechanisms of biouptake and toxicity. The fast-moving nature of the field and the quality of the
submissions make this book essential reading for all those working
in this area. It is suitable for researchers from Masters-level
upwards, and for regulators and industry. The book can also be used
as a high-level teaching aid.
