In this thesis, Claudia Backes guides the reader through her multidisciplinary research into the non-covalent functionalization of carbon nanotubes in water. Although one of the most remarkable materials of the 21st century, carbon nanotubes often have limited application because of their intrinsically low solubility and polydispersity. The author shows that rational surfactant design is a powerful tool for chemists because it can unmask the key to solubilization and allow us to tailor nanotube surface and optical properties in a fully reversible fashion. Aspects of organic, physical and analytical chemistry, as well as colloidal sciences are covered in this outstanding work which brings us one step closer to exploiting this super-material to its full potential.

This book covers different omics aspects related to the extracellular matrix (ECM), namely specific omics resources focused on the extracellular matrix (e.g., databases, repositories and atlases), quantitative proteomics applied to specific extracellular matrices (e.g. basement membranes), biological processes such as ECM degradation (degradomics), cell-matrix interactions (adhesomes), signaling pathways, biomarker discovery and diseases, and interactomics (extracellular matrix interaction networks including not only protein-protein but also protein-glycosaminoglycan interactions). The volume also includes recent advances in glycomics and glycobioinformatics applied to proteoglycans and glycosaminoglycans, which are key biological players. The use of omics data to build dynamic models of ECM-regulated biological pathways is addressed, together with the requirement to standardize omic data, which is a prerequisite for the FAIR (Findability, Accessibility, Interoperability, and Reusability) guiding principles for scientific data management. This book will be of great interest to a broad readership from beginners to advanced researchers, who are interested in extracellular matrix omics and will inspire future research topics.
My Way to Lithium-Ion Batteries Yoshio Nishi I have been engaged in research and development (R&D) on novel materials for electronic appliances for 40 years since I joined Sony Corporation in 1966. I started my scientific career in Sony as a researcher of zinc-air batteries. After 8 years in R&D on electrochemistry, my research field was shifted against my will to el- troacoustic materials, specifically diaphragm materials for electroacoustic tra- ducers including loudspeakers, headphones, and microphones. My R&D work also extended to cabinet materials for speaker systems. This about-face was uncomfo- able for me at first, but it forced me to devote myself to the investigation of various classes of materials unfamiliar to me, covering pulp and paper, metals (i. e. , Ti, Al, Be), ceramics (B4C, TiN, BN, SiC), carbonaceous materials (carbon fibers, intr- sic carbon, artificial diamond), reinforcing fibers for FRP (carbon fibers, aromatic polyamide fibers, glass fibers, SiC fibers, superdrawn polyethylene fibers), organic polymers (polyamides, polyethylene, polypropylene, polymethylpentene, poly- ides, polysulfones, polyetherimides, polyethersulfones, PET), boards (plywood, particle board), resin composites (bulk molding compounds, resin concretes, arti- cial marble), and so on. I also was engaged in development of piezoelectric lo- speakers employing poly(vinylidene difluoride) (PVdF). The remarkably successful output from my R&D activities in those days were organic polymer whiskers and bacterial cellulose. The former was the first organic whisker in the world disc- ered by M. Iguchi,1 which is composed of polyoxymethylene (POM).

Chemical additives are used to enhance the properties of many industrial products. Since their release into the environment is a potential risk for man and nature, their fate and behavior have been investigated in the framework of the European Union-funded project RISKCYCLE. The results are presented in two volumes, Global Risk-Based Management of Chemical Additives I: Production, Usage and Environmental Occurrence and Global Risk-Based Management of Chemical Additives II: Risk-Based Assessment and Management Strategies. This book is the second of the two volumes and features two main parts. In the first part, experts in the field discuss different models related to the assessment of the potential risks posed by chemical additives and analyze their benefits and drawbacks. In the second part, specific case studies in which the models have been applied are presented and the reliability of the models is evaluated. This volume is an invaluable source of information for scientists and governmental agencies dealing with the risk assessment of chemicals on a global scale.
This book presents an overview of fundamental aspects of surface-based biosensors and techniques for enhancing their detection sensitivity and speed. It focuses on rapid detection using miniaturized sensors and describes the physical principles of nanoscale transducers, surface modifications, microfluidics and reaction engineering, diffusion and kinetics. A key challenge in the field of bioanalytical sensors is the rapid delivery of target biomolecules to the sensing surface. While various nanostructures have shown great promise in sensitive detection, diffusion-limited binding of analyte molecules remains a fundamental problem. Recently, many researchers have put forward novel schemes to overcome this challenge, such as nanopore channels, electrokinetics, and dielectrophoresis, to name but a few. This book provides the readers an up-to-date account on these technological advances.
Fluorescent proteins are intimately connected to research in the life sciences. Tagging of gene products with fluorescent proteins has revolutionized all areas of biosciences, ranging from fundamental biochemistry to clinical oncology, to environmental research. The discovery of the Green Fluorescent Protein, its first, seminal application and the ingenious development of a broad palette of fluorescence proteins of other colours, was consequently recognised with the Nobel Prize for Chemistry in 2008. "Fluorescent Proteins II" highlights the physicochemical and biophysical aspects of fluorescent protein technology beyond imaging. It is tailored to meet the needs of physicists, chemists and biologists who are interested in the fundamental properties of fluorescent proteins, while also focussing on specific applications. The implementations described are cutting-edge studies and exemplify how the physical and chemical properties of fluorescent proteins can stimulate novel findings in life sciences.

The two volumes of Handbook of Gas Sensor Materials provide a detailed and comprehensive account of materials for gas sensors, including the properties and relative advantages of various materials. Since these sensors can be applied for the automation of myriad industrial processes, as well as for everyday monitoring of such activities as public safety, engine performance, medical therapeutics, and in many other situations, this handbook is of great value. Gas sensor designers will find a treasure trove of material in these two books.
Since the independent invention of DNA sequencing by Sanger and by
Gilbert 30 years ago, it has grown from a small scale technique
capable of reading several kilobase-pair of sequence per day into
today's multibillion dollar industry. This growth has spurred the
development of new sequencing technologies that do not involve
either electrophoresis or Sanger sequencing chemistries. Sequencing
by Synthesis (SBS) involves multiple parallel micro-sequencing
addition events occurring on a surface, where data from each round
is detected by imaging.
This review series covers trends in modern biotechnology, including all aspects of this interdisciplinary technology, requiring knowledge, methods, and expertise from chemistry, biochemistry, microbiology, genetics, chemical engineering and computer science.

This book shows the availability and potential of the coupled acoustic-gravitational (CAG) field for trace-level biosensing. The proposed detection scheme also allows the evaluation of the kinetics and thermodynamics of the reaction occurring on a single microparticle (MP). This method has wide applicability in important fields, involving not only chemistry but also life, environmental, and medical sciences. The author proposes novel trace-level biosensing based on measurements of the levitation coordinate shift of an MP in the CAG field. The levitation coordinate of the MP in the CAG field is determined by its density and compressibility. The levitation coordinate shift is induced by the binding of gold nanoparticles (AuNPs) to the MP through interparticle reactions. Therefore, the quantity of molecules involved in the reaction can be determined from the levitation coordinate shift. The author demonstrates the zmol level detection for biotin, DNA/RNA, and organic molecules. In addition, the kinetics and thermodynamics are evaluated for various reactions occurring between the MP and AuNP, such as the avidin-biotin reaction, direct hybridization, sandwich hybridization, and aptamer-target complexation. This book provides a new concept based on the CAG field, in which the extent of a reaction is converted into the levitation coordinate shift, that is, "length." The proposed method has many advantages over other methods, e.g., high biocompatibility, high applicability, and short analysis time. In addition, because the apparatus used in this study is inexpensive and easy to miniaturize, this method is useful in important practical fields, such as forensic and environmental science and diagnosis. Thus, this book inspires many researchers to apply the present method to their own fields of interest.
The book starts with an introduction on silicon isotopes and related analytical methods, and explains the mechanisms of silicon isotope fractionation. Silicon isotope distributions in lithosphere, hydrosphere and biosphere are shown based on results from field studies, and silicon isotope relevance for applications are presented.
Channels of nanotubular dimensions exist in a variety of materials (examples are carbon nanotubes and the nanotubular channels of zeolites and zeotypes) and show promise for numerous applications due to their unique properties. One of their most important properties is their capacity to adsorb molecules and these may exist in a variety of phases. "Adsorption and Phase Behaviour in Nanochannels and Nanotubes" provides an excellent review of recent and current work on adsorption on nanometerials. It is an impressive collection of papers dealing with the adsorption and phase behaviour in nanoporous materials from both experimental and theoretical perspectives. "Adsorption and Phase Behaviour in Nanochannels and Nanotubes" focuses on carbon nanotubes as well as zeolites and related materials.
