Electrophosphorescent Materials and Devices

Electrophosphorescent Materials and Devices

Organic LEDs (OLEDs) in mobile displays have been in large-scale production for over a decade and OLED-based televisions are rapidly gaining traction in the marketplace. OLEDs are on the verge of entering the solid-state lighting market in a big way. The OLED technology gives higher color purity and is more efficient than any of the competing technologies. When produced at scale OLEDs are also economical. A key limitation in the development of OLEDs was the efficient conversion of all of the electrical energy put into the device into light. Until the late 1990s the maximum efficiency of OLEDs was limited to 25% (photons/electrons) but this limitation was removed and OLEDs with 100% efficiency were reported in the early 2000s. This advance in OLED technology was driven by the author of this book. He and his collaborators developed electrophosphorescence which is essential in reaching the 100% efficiency that is now commonplace in commercial devices. | Electrophosphorescent Materials and Devices

Mullite Formations Analysis and Applications

Mullite Formations Analysis and Applications

Mullite is the most important crystalline phase in fired products belonging to the Al2O3–SiO2 mullite system such as whiteware articles used in daily life (e. g. low- and high-temperature hard porcelain sanitaryware and structural clay products). Mullite has attracted increasing interest due to its excellent high-temperature strength and creep resistance good chemical and thermal stability low thermal expansion coefficient and good dielectric properties. Mullitization has been a subject of extensive and controversial investigations. This book comprehensively covers the synthesis and six types of phase transformation of mullite. Part I reviews previous research on the synthesis of mullite gels advantages and disadvantages of different chemical routes of synthesis and phase transformation processes. Part II discusses the nature and characterization of spinel and mullite phases and different mechanisms of mullite formation as conjectured by various researchers. Part III deals with the critical analysis of the spinel and mullite phases and evolution of mullite formation routes. Every chapter is accompanied by detailed diagrams and a comprehensive list of references. | Mullite Formations Analysis and Applications

The Theory of Everything Quantum and Relativity is everywhere – A Fermat Universe

The Theory of Everything Quantum and Relativity is everywhere – A Fermat Universe

The book unifies quantum theory and the general theory of relativity. As an unsolved problem for about 100 years and influencing so many fields this is probably of some importance to the scientific community. Examples like Higgs field limit to classical Dirac and Klein–Gordon or Schrödinger cases quantized Schwarzschild Kerr Kerr–Newman objects and the photon are considered for illustration. An interesting explanation for the asymmetry of matter and antimatter in the early universe was found while quantizing the Schwarzschild metric. | The Theory of Everything Quantum and Relativity is everywhere – A Fermat Universe

Physics and Future of Hurricanes

Physics and Future of Hurricanes

This monograph is about hurricanes prompted by a discovery that suggests they will become more powerful with global warming. It provides at a college physics level a basic understanding of hurricanes emphasizing the flow of energy into and out of these storms and as a textbook covers some material that might be taught in meteorology or atmospheric physics courses. The text is centered on a new discovery that is not in any existing textbook. Because of the new discovery the book is of immediate interest to all meteorologists. It turns out that hurricanes as revealed by the new discovery are usefully regarded as a separate phase of matter bringing in characteristic temperature dependences near their transitions. The role of phase change in understanding hurricanes brings in the 20th-century discoveries in theoretical physics relating to critical phenomena with non-intuitive values of the critical exponent β entering the formula P = const (T – Tc)β where P is a characteristic strength parameter or order parameter of the phase of matter appearing at Tc. According to the new discovery on hurricanes it appears that taking the wind velocity as the order parameter P the critical exponent is near 1/3. In a second discovery we find that a small correction to this value is brought in by the complicated physics of the renormalization group that earned K. G. Wilson the Nobel Prize in Physics in 1982. | Physics and Future of Hurricanes

Microbial Infections and Cancer Therapy

Microbial Infections and Cancer Therapy

This book deals with the emerging concept that certain pathogenic bacteria and viruses when infecting people with cancer actively fight tumors allowing their regression. Although such observations go back more than 100 years use of specific bacterial strains or viruses usually genetically modified with known anticancer drugs and their protein/peptide products has gained ground in recent years allowing significant cancer regression in clinical trials with stage III/IV cancer patients or even in pediatric brain tumor patients often without any demonstration of toxicity. It is composed of 12 chapters written by pioneers in microbial biotech and cancer research and covers the emerging roles of various microorganisms and their products in cancer therapy. The book highlights the benefits of using conventional cancer treatments (such as chemo- and radiotherapies) with microbial-based therapies. Such combinatorial therapies have gained particular attention as a strategy to overcome drug resistance and the readers of the book will discover their impact on fundamental research and promising results from clinical trials. | Microbial Infections and Cancer Therapy

Lithium Niobate Nanophotonics

Lithium Niobate Nanophotonics

Photonic integrated circuit (PIC) technology holds great potential for breaking through the bottlenecks in current photonic and optoelectronic networks. Recently a revolution has been witnessed in the field of lithium niobate (LN) photonics. Over the past decade nanoscale LN waveguides with a propagation loss of ~0. 01 dB and a radius of curvature on the level of ~100 μm have been demonstrated. The revolution mainly benefits from two technological advancements the maturity of lithium-niobate-on-insulator (LNOI) technology and the innovation of nanofabrication approaches of high-quality LNOI photonic structures. Using low-loss waveguides and high-quality-factor (high-Q) microresonators produced on the LNOI platform as building blocks various integrated photonic devices have been demonstrated with unprecedented performances. The breakthroughs have reshaped the landscape of the LN industry. This is the first monograph on LN nanophotonics enabled by the LNOI platform. It comprehensively reviews the development of fabrication technology investigations on nonlinear optical processes and demonstrations of electro-optical devices as well as applications in quantum light sources spectroscopy sensing and microwave-to-optical wave conversion. The book begins with an overview of the technological evolution of PICs justifying the motivation for developing LNOI photonics. The next four chapters focus on LNOI photonics. The book concludes with a summary of the milestone achievements discussed in these chapters and provides a future perspective of this area of research. | Lithium Niobate Nanophotonics

Mass Spectrometry

Mass Spectrometry

It is estimated that there are about 10 million organic chemicals known and about 100 000 new organic compounds are produced each year. Some of these new chemicals are made in the laboratory and some are isolated from natural products. The structural determination of these compounds is the job of the chemist. There are several instrumental techniques used to determine the structures of organic compounds. These include NMR UV/visible infrared spectroscopy mass spectrometry and X-ray crystallography. Of all the instrumental techniques listed infrared spectroscopy and mass spectrometry are the two most popular techniques mainly because they tend to be less expensive and give us the most structural information. This book is an introductory text designed to acquaint undergraduate and graduate students with the basic theory and interpretative techniques of mass spectrometry. Much of the material in this text has been used over a period of several years for teaching courses in materials characterization and chemical analysis. It presents the mass spectra of the major classes of organic compounds and correlates the fragmentation pattern of each spectrum with the structural features of the compound it represents. This has been done for hydrocarbons organic acids ketones aldehydes esters anhydrides phenols amines and amides. The text discusses the origin of the fragments techniques innovations and applications in mass spectrometry. It is interspersed with many illustrations examples an adequate but not overwhelming bibliography and problems for students. It will serve as a lecture text for a one-semester course in mass spectrometry or can be used to teach the mass spectra portion of a broader course in material characterization and chemical analysis.
