This book focuses on the morphology, exine ornamentation and the associated evolutionary trends of crabapple pollen and anatomical developmental patterns. To examine the genetic evolutionary patterns of crabapple pollen traits, we constructed an interval distribution function based on characteristic pollen parameters and used a binary trivariate data matrix (Xi Yi Zi) to reflect the exine ornamentation regularity of the pollen. Our findings should inform the taxonomic status of the genus Malus. Pollen electron micrographs from a total of 26 species and 81 cultivars of Malus were recorded in this book. All 107 figures and 642 scanned pollen images constitute primary data obtained by the authors. The images in this book are clear, three-dimensional, and aesthetically pleasing. They are accompanied with text descriptions and provided a method for the indication of the different types of information that can be expected. This book can provide a reference for scientific researchers, students, and teachers in tertiary institutions that are engaged in research concerning crabapple production.

With respect to chemical applications, surface-launched acoustic wave sensors were originally developed as sensing devices for specific chemical and biological species, but more recently have been applied to the study of thin film and interfacial properties. These devices exploit the phenomenon of piezoelectricity, the instigation of mechanical motion in solids by oscillating electrical fields. This text/reference presents the principles of design and operation of these sensors and explores their traditional and emerging applications with a focus on devices that employ acoustic waves launched and received on the same surface.

The book begins with a review of piezoelectricity and the genesis of acoustic wave devices, and the advent of chemical sensor technology. Subsequent chapters explore acoustic waves in solids and device structure, theory of acoustic wave response, and the various categories of acoustic wave device. The book describes the design of these devices and how they are applied in chemistry for the detection of species present in the gas and liquid phase, as well as the study of thin films placed on the sensor surface. Other topics covered include polymeric glass transitions, polymer properties, biosensor technology, and the development of sensor arrays. Each of the various types of device is examined with a view toward its application in chemistry in general and analytical chemistry in particular.

Presenting the most up-to-date information available on this rapidly evolving technology, and supplemented with scores of helpful illustrations and tables, Surface-Launched Acoustic Wave Sensors draws information from such diverse areas of scientific investigation as acoustic wave physics, applied mathematics, chemistry, electronics, fluid mechanics, materials science, piezoelectricity, and polymer science. The material presented on these topics is both self-consistent and readable for the nonexpert—allowing industrial chemists, graduate students, and undergraduates to gain a deeper understanding of these devices, their designs, and applications.

A focused and accessible presentation of a burgeoning new technology

This book concerns the design, operation, and application of devices capable of generating acoustic waves in the ultrasonic frequency range. The clear emphasis of the text is the study of chemical and/or biochemical systems imposed on the surface of such devices, whether operated in the gas or liquid phase, i.e., on acoustic wave chemical and biological sensors.

The participation in interlaboratory studies and the use of Certified Reference Materials (CRMs) are widely recognised tools for the verification of the accuracy of analytical measurements and they form an integral part of quality control systems used by many laboratories, e.g. in accreditation schemes. As a response to the need to improve the quality of environmental analysis, the European Commission has been active in the past fifteen years, through BCR activity (now renamed Standards, Measurements and Testing Programme) in the organisation of series of interlaboratory studies involving expert laboratories in various analytical fields (inorganic, trace organic and speciation analysis applied to a wide variety of environmental matrices). The BCR and its successor have the task of helping European laboratories to improve the quality of measurements in analytical sectors which are vital for the European Union (biomedical, agriculture, food, environment and industry); these are most often carried out in support of EC regulations, industrial needs, trade, monitoring activities (including environment, agriculture, health and safety) and, more generally, when technical difficulties hamper a good comparability of data among EC laboratories. The collaborative projects carried out so far have placed the BCR in the position of second world CRM producer (after NIST in the USA).

"Interlaboratory Studies and Certification of Reference Materials for Environmental Analysis" gives an account of the importance of reference materials for the quality control of environmental analysis and describes in detail the procedures followed by BCR to prepare environmental reference materials, including aspects related to sampling, stabilization, homogenisation, homogeneity and stability testing, establishment of reference (or certified) values, and use of reference materials. Examples of environmental CRMs produced by BCR within the last 15 years are given, which represent more than 70 CRMs covering different types of materials (plants, biological materials, waters, sediments, soils and sludges, coals, ash and dust materials) certified for a range of chemical parameters (major and trace elements, chemical species, PAHs, PCBs, pesticides and dioxins).

The final section of the book describes how to organise improvement schemes for the evaluation method and/or laboratory performance. Examples of interlaboratory studies (learning scheme, proficiency testing and intercomparison in support to prenormative research) are also given.

For many years, evidence suggested that all solid materials either possessed a periodic crystal structure as proposed by the Braggs or they were amorphous glasses with no long-range order. In the 1970s, Roger Penrose hypothesized structures (Penrose tilings) with long-range order which were not periodic. The existence of a solid phase, known as a quasicrystal, that possessed the structure of a three dimensional Penrose tiling, was demonstrated experimentally in 1984 by Dan Shechtman and colleagues. Shechtman received the 2011 Nobel Prize in Chemistry for his discovery. The discovery and description of quasicrystalline materials provided the first concrete evidence that traditional crystals could be viewed as a subset of a more general category of ordered materials. This book introduces the diversity of structures that are now known to exist in solids through a consideration of quasicrystals (Part I) and the various structures of elemental carbon (Part II) and through an analysis of their relationship to conventional crystal structures. Both quasicrystals and the various allotropes of carbon are excellent examples of how our understanding of the microstructure of solids has progressed over the years beyond the concepts of traditional crystallography.

This book describes modern focused ion beam microscopes and techniques and how they can be used to aid materials metrology and as tools for the fabrication of devices that in turn are used in many other aspects of fundamental metrology. Beginning with a description of the currently available instruments including the new addition to the field of plasma-based sources, it then gives an overview of ion solid interactions and how the different types of instrument can be applied. Chapters then describe how these machines can be applied to the field of materials science and device fabrication giving examples of recent and current activity in both these areas.

This volume is a new follow-up volume that complements Dynamic Light Scattering (1993) by the same author. The volume is directed to the recent development in the light scattering technique and to describing a wide spectrum of its applications. Both the theoretical development and utilization are traced by authors who are expert in their fields. Development in static light scattering as applied to simple liquids, polymer solutions, and multi-component polymer mixtures are dealt with. The scattering theory of colloidal dispersions is described and scattering from rod-like polyelectolytes is reviewed. There are chapters on concentrated polymer systems, aggregation phenomena, polymer-polymer interactions, polyelectrolytes in solution. Emphasis is given to more complex systems, for example, ternary polymer systems, complex micellar systems, and block copolymers in the ordered and disordered states. Low-angle light scattering is reviewed, as well as simultaneous static and dynamic light scattering. The determination of particle size distributions and combined chromatographic light scattering techniques are also treated.

Originally published in 1665, Micrographia is the most famous and influential work of English scholar ROBERT HOOKE (1635-1703), a notable member of the Royal Society and the scientist for whom Hooke's Law of elasticity is named. Here, Hooke describes his observations of various household and biological specimens, such as the eye of a fly and the structure of plants, and became the first person to use the term cell in biology, as the cells in plants reminded him of monk's living quarters. In addition to his studies using a microscope, Hooke also discusses the heavenly bodies as visible through a telescope. Students of science and the history of science will find Hooke's early forays into biology and optics a good primer for further learning.

This book illustrates the practical workings of environmental transmission electron microscopy (ETEM) from history and instrument design through to solving practical problems. Aspects of instrument design, performance, and operating procedures are covered, together with common problems and pitfalls of the technique. Not only will a properly operated instrument and a carefully set up experiment provide new insight into your specimen, but the ability to observe the specimen in its natural habitat will be essential to meeting specific design criteria for the development of the next generation of materials. Over the past five decades, transmission electron microscopy (TEM) under environmental conditions relevant to a particular sample has been of increasing interest. Symposia dealing with the topic are now among the best attended at international microscopy conferences. Since typical operating modes for the ETEM require the sample be subjected to a harsh environment consisting of corrosive gases and high temperatures, the challenges of adapting and operating the instrument for observation under dynamic operating conditions are numerous. However, careful consideration of the interaction of the electrons with the gases and sample, as well as the gases with the microscope components, can lead to highly rewarding results. In Controlled Atmosphere Transmission Electron Microscopy, leading experts help you to perform successful experiments using the ETEM, and to interpret and understand the results.

Since its inception, patch-clamp has continued to be widely considered the gold standard method to record ion channel activity.

The electric dipole moment (EDM) challenge measures a non-zero proton EDM value and this book suggests how the challenge can be met. Any measurably large proton EDM would violate the standard model. The method to be employed uses an intense beam of 'frozen spin' protons circulating for hour-long times in a storage ring 'trap'. The smallness of EDMs allows them to test existing theories, but also makes them hard to measure. Such EDM experiments are inexpensive, at least compared to building accelerators of ever-greater energy.

This thesis describes novel approaches and implementation of high-resolution microscopy in the extreme ultraviolet light regime. Using coherent ultrafast laser-generated short wavelength radiation for illuminating samples allows imaging beyond the resolution of visible-light microscopes. Michael Zurch gives a comprehensive overview of the fundamentals and techniques involved, starting from the laser-based frequency conversion scheme and its technical implementation as well as general considerations of diffraction-based imaging at nanoscopic spatial resolution. Experiments on digital in-line holography and coherent diffraction imaging of artificial and biologic specimens are demonstrated and discussed in this book. In the field of biologic imaging, a novel award-winning cell classification scheme and its first experimental application for identifying breast cancer cells are introduced. Finally, this book presents a newly developed technique of generating structured illumination by means of so-called optical vortex beams in the extreme ultraviolet regime and proposes its general usability for super-resolution imaging.

The volume forms a part of the celebrations marking the anniversary of the invention of the telescope. From its Renaissance beginnings to yesterday's Cold War, the essays contributed here throw a spotlight on a number of significant episodes in the continuing adventures of this well-loved instrument, which has played a crucial role in Man's thinking about his position - literally and philosophically - in the universe. Drawn from various conferences held by the Scientific Instrument Commission of the International Union of the History and Philosophy of Science between 2007 and 2009, these papers make a substantial contribution to our current knowledge about this fascinating optical instrument.
