This thesis presents first observations of superconductivity in one- or two-atomic-scale thin layer materials. The thesis begins with a historical overview of superconductivity and the electronic structure of two-dimensional materials, and mentions that these key ingredients lead to the possibility of the two-dimensional superconductor with high phase-transition temperature and critical magnetic field. Thereafter, the thesis moves its focus onto the implemented experiments, in which mainly two different materials thallium-deposited silicon surfaces and metal-intercalated bilayer graphenes, are used. The study of the first material is the first experimental demonstration of both a gigantic Rashba effect and superconductivity in the materials supposed to be superconductors without spatial inversion symmetry. The study of the latter material is relevant to superconductivity in a bilayer graphene, which was a big experimental challenge for a decade, and has been first achieved by the author. The description of the generic and innovative measurement technique, highly effective in probing electric resistivity of ultra-thin materials unstable in an ambient environment, makes this thesis a valuable source for researchers not only in surface physics but also in nano-materials science and other condensed-matter physics.
Recent studies have shown that novel processing and modeling techniques may be used to create patient-specific prostheses, artificial tissues, and other implants using data obtained from magnetic resonance imaging, computed tomography, or other imaging techniques. For example, customized prostheses may be fabricated that possess suitable features, including geometry, size, and weight, for a given medical condition. Many advances have been made in the development of patient-specific implants in the past decade, yet this information is not readily available to scientists and students. Printed Biomaterials: Novel Processing and Modeling Techniques for Medicine and Surgery provides the biomaterials scientist and engineer, as well as advanced undergraduate or graduate students, with a comprehensive discussion of contemporary medical implant research and development. The development of printed biomaterials is multidisciplinary, and includes concepts traditionally associated with engineering, materials science, medicine, and surgery. This text highlights important topics in these core fields in order to provide the fundamentals necessary to comprehend current processing and modeling technologies and to develop new ones.

This book is available as open access through the Bloomsbury Open Access programme and is available on www.bloomsburycollections.com. This book defines 'nanowares' as the ideas and products arising out of nanotechnology. Koepsell argues that these rapidly developing new technologies demand a new approach to scientific discovery and innovation in our society. He takes established ideas from social philosophy and applies them to the nanoparticle world. In doing so he breaks down the subject into its elemental form and from there we are better able to understand how these elements fit into the construction of a more complex system of products, rules and regulations about these products. Where existing research in the field has tended to focus on potential social harm, Koepsell takes a different approach by looking at ways in which developments in distributed design and fabrication can be harnessed to enable wealth creation by those with good ideas but no access to capital. He argues that the key challenge facing us is the error implicit in current intellectual property regimes and presents new modes of relating inventors to artifacts in this new context. In conclusion he offers contractual models which he believes encourage innovation in nano-media by embracing open source and alternative means of protection for innovators.
This book underscores the essential principles of photocatalysis and provides an update on its scientific foundations, research advances, and current opinions, and interpretations. It consists of an introduction to the concepts that form the backbone of photocatalysis, from the principles of solid-state chemistry and physics to the role of reactive oxidizing species. Having recognised the organic link with chemical kinetics, part of the book describes kinetic concepts as they apply to photocatalysis. The dependence of rate on the reaction conditions and parameters is detailed, the retrospective and prospective aspects of the mechanism of photocatalysis are highlighted, and the adsorption models, photocatalytic rate expressions, and kinetic disguises are examined. This book also discusses the structure, property, and activity relationship of prototypical semiconductor photocatalysts and reviews how to extend their spectral absorption to the visible region to enable the effective use of visible solar spectrum. Lastly, it presents strategies for deriving substantially improved photoactivity from semiconductor materials to support the latest applications and potential trends.

This book surveys the new materials and approaches needed to use nanotechnology to introduce the next generation of advanced lithium batteries, currently the most promising energy storage devices available. It provides an overview of nanotechnology for lithium batteries from basic to applied research in selected high technology areas. The book especially focuses on near-term and future advances in these fields. All contributors to this book are expert researchers on lithium batteries.
This book provides expert coverage of modern and novel aspects of the study of vortex matter, dynamics, and pinning in nanostructured and multi-component superconductors. Vortex matter in superconducting materials is a field of enormous beauty and intellectual challenge, which began with the theoretical prediction of vortices by A. Abrikosov (Nobel Laureate). Vortices, vortex dynamics, and pinning are key features in many of today's human endeavors: from the huge superconducting accelerating magnets and detectors at the Large Hadron Collider at CERN, which opened new windows of knowledge on the universe, to the tiny superconducting transceivers using Rapid Single Flux Quanta, which have opened a revolutionary means of communication. In recent years, two new features have added to the intrinsic beauty and complexity of the subject: nanostructured/nanoengineered superconductors, and the discovery of a range of new materials showing multi-component (multi-gap) superconductivity. In this book, leading researchers survey the most exciting and important recent developments in the field. Topics covered include: the use of scanning Hall probe microscopy to visualize interactions of a single vortex with pinning centers; Magneto-Optical Imaging for investigating what vortex avalanches are, why they appear, and how they can be controlled; and the vortex interactions responsible for the second magnetization peak. Other chapters discuss nanoengineered pinning centers of vortices for improved current-carrying capabilities, current anisotropy in cryomagnetic devices in relation to the pinning landscape, and the new physics associated with the discovery of new superconducting materials with multi-component superconductivity. The book offers something for almost everybody interested in the field: from experimental techniques to visualize vortices and study their dynamics, to a state-of-the-art theoretical microscopic approach to multicomponent superconductivity.

The thesis presents an original and smart way to manipulate liquid and polymeric materials using a "pyro-fluidic platform" which exploits the pyro-electric effect activated onto a ferroelectric crystal. It describes a great variety of functionalities of the pyro-electrohydrodynamic platform, such as droplet self-assembling and dispensing, for manipulating multiphase liquids at the micro- and nanoscale. The thesis demonstrates the feasibility of non-contact self-assembling of liquids in plane (1D) using a micro engineered crystal, improving the dispensing capability and the smart transfer of material between two different planes (2D) and controlling and fabricating three-dimensional structures (3D). The thesis present the fabrication of highly integrated and automated 'lab-on-a-chip' systems based on microfluidics. The pyro-platform presented herein offers the great advantage of enabling the actuation of liquids in contact with a polar dielectric crystal through an electrode-less configuration. The simplicity and flexibility of the method for fabricating 3D polymer microstructures shows the great potential of the pyro-platform functionalities, exploitable in many fields, from optics to biosensing. In particular, this thesis reports the fabrication of optically active elements, such as nanodroplets, microlenses and microstructures, which have many potential applications in photonics. The capability for manipulating the samples of interest in a touch-less modality is very attractive for biological and chemical assays. Besides controlling cell growth and fate, smart micro-elements could deliver optical stimuli from and to cells monitoring their growth in real time, opening interesting perspectives for the realization of optically active scaffolds made of nanoengineered functional elements, thus paving the way to fascinating Optogenesis Studies.

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. |
