Metal Matrix Composites
Metal matrix composites (MMCs) have become real engineering materials. MMCs have gone from "niche" materials to several high performance applications in aerospace, electronic packaging, automotive, and recreational products. This text focuses on the synergistic relationships among processing, microstructure, and properties of metal matrix composites. An introductory chapter is followed by a chapter each on reinforcements and common matrix materials. A chapter on the very important topic of processing of MMC is then presented. This is followed by a chapter on interfaces in MMCs, their characterization and techniques to obtain interfacial properties. Next there are chapters on monotonic mechanical and physical properties; followed by cyclic fatigue, creep, and wear resistance. We conclude with a chapter on applications of MMCs. The book is well-suited for upper level undergraduate students, graduate students, and as general source of reference on the subject for the professionals in the field.
Metal Catalyzed Reductive C-C Bond Formation : A Departure from Preformed Organometallic Reagents
The prototypical catalytic reductive C–C bond formations, the Fischer-Tropsch reaction [1] and alkene hydroformylation [2], were discovered in 1922 and 1938, respectively [3,4]. These processes, which involve reductive coupling to carbon monoxide, have long been applied to the industrial manufacture of commodity chemicals [5]. Notably, alkene hydroformylation, also known as the oxo-synthesis, has emerged as the largest volume application of homogeneous metal catalysis, accounting for the production of over 7 million metrictons of aldehyde annually. Despite the impact of these prototypical reductive C–C bond formations, this field of research lay fallow for several decades.
Metal Catalyzed Cascade Reactions
Transition metal-catalyzed cascade reactions are an elegant approach to complex molecular scaffolds. Besides their esthetics and increase in structural complexity, they have also become mechanistic challenges for the combination of organometallic elementary steps. As a consequence, cascade reactions have revolutionized synthetic strategies and conceptual thinking. The authors highlight cyclization via carbopalladation and acylpalladation and Heck-pericyclic sequences. They discuss p-allyl palladium-based cascade reactions, Michael-type additions as an entry to transition-metal-promoted cyclizative transformations, and sequential or consecutive palladium-catalyzed processes, and show Pauson-Khand cascades, metal-catalyzed cyclizations of acyclic precursors, as well as cascade and sequential ruthenium-catalyzed transformations. Therefore, the reader finds overview of an exciting and highly dynamic field of a new and innovative methodological concept

Messenger RNA therapeutics
Focuses on the fundamentals and applications of messenger RNA (mRNA)-based therapeutics and discusses the strengths and key challenges of this emerging class of drugs. In the past 30 years, extensive research and technological development in many areas have contributed to the emergence of in vitro transcribed mRNA as a therapeutic that has now reached clinical testing. Formulations that protect the mRNA from nucleases and accelerate its cellular uptake, combined with improvements to the mRNA molecules themselves, have been critical advancements for mRNAs to become viable therapeutics. Though once regarded as a serious impediment, the transient nature of mRNA technology is now considered a major advantage in making mRNA therapies safe and, ultimately, a potential game changer in the field of medicine. This new book in the RNA Technologies series provides a state-of-the-art overview on the emerging field of mRNA therapeutics covering essential strategies for formulation, delivery, and application. It also reviews the promising role in cancer immunotherapy, respiratory diseases, and chronic HBV infection and discusses RNA vaccines in light of the current COVID-19 pandemic. mRNA-based approaches have great potential to revolutionize molecular biology, cell biology, biomedical research, and medicine.
Meshfree Methods for Partial Differential Equations IV
The numerical treatment of partial differential equations with particle methods and meshfree discretization techniques is a very active research field both in the mathematics and engineering community. Due to their independence of a mesh, particle schemes and meshfree methods can deal with large geometric changes of the domain more easily than classical discretization techniques. Furthermore, meshfree methods offer a promising approach for the coupling of particle models to continuous models. This volume of LNCSE is a collection of the proceedings papers of the Fourth International Workshop on Meshfree Methods held in September 2007 in Bonn. The articles address the different meshfree methods (SPH, PUM, GFEM, EFGM, RKPM, etc.) and their application in applied mathematics, physics and engineering. The volume is intended to foster this very active and exciting area of interdisciplinary research and to present recent advances and results in this field.

MEMS/NEMS : (1) Handbook Techniques and Applications Design Methods, (2) Fabrication Techniques, (3) Manufacturing Methods, (4) Sensors and Actuators, (5) Medical Applications and MOEMS
Micro-Electro Mechanical Systems (MEMS) is the integration of mechanical elements, sensors, actuators, and electronics on a common silicon substrate. While the electronics are fabricated using integrated circuit (IC) process sequences (e.g., CMOS, Bipolar, or BICMOS processes),the micromechanical components are fabricated using compatible micromachining processes that selectively etch away parts of the silicon wafer or add new structural layers to form the mechanical and electromechanical devices. MEMS promises to revolutionize nearly every product category by bringing together silicon-based microelectronics with micromachining technology, thereby, making possible the realization of complete systems-on-a-chip.
