Book Description
This book deals with the difference electron nanoscope (DEN), whose principles have been invented and realised by the book author. The DEN is based on a smart combination of diffractometric and spectroscopic data and uses a visualisation of three-dimensional difference electron densities (in our case stemming from 3d orbitals) in order to obtain the key quantity involved, the electric field gradient (efg). However, the DEN is no machine, as the title of the book might infer. It is a computer program running on a fast computer system displaying 3D difference electron hyperareas floating in space and the relevant efg as a wire frame model within the unit cell of the sample involved. In this sense, it acts on a sub-nanometer scale (hence the term "nanoscope") and generates images of uncompared symmetrical and physical evidence—and beauty. For the first time, diffractometry and spectroscopy have been integrated for the common synergetic effects that may contribute to a better understanding of electric and magnetic interactions in a crystal. The experimental derivation of the common quantity, the efg, is not confined to iron-containing samples, as the use of Mössbauer spectroscopy might infer, but can also be determined by nuclear quadrupole resonance that is not confined to special nuclides. Hence, the DEN can be applied to a huge multitude of scientifically interesting specimens since the main method involved, diffractometry in a wide sense, has no general limitations at all. So it is a rather universal method, and the monograph might contribute to a wide distribution of the method in the scientific world. Has anyone seen a real orbital before: a real orbital distribution in a crystal unit cell together with its efg tensor ellipsoid? In this book, one can see it.

Book Description
This book deals with the difference electron nanoscope (DEN), whose principles have been invented and realised by the book author. DEN is a software program that displays 3D difference electron hyperareas floating in space and the relevant efg as a wire frame model within the unit cell of the sample involved. For the first time, diffractometry and spectroscopy have been joined to common synergetic effects that may contribute to a better understanding of electric and magnetic interactions in a crystal. The monograph might contribute to a wide distribution of the method in the scientific world.

Book Description
All solids are composed of atoms or molecules and in order to explain their behavior, experiments and theories came forward. Simultaneously, many new materials were synthetically and systematically developed in the laboratories, properties of which needed to be understood before deploying them in various technologies. It is known that there is a strong correlation between structure and properties of materials. Therefore, experiments on solids involve understanding their structure with diffraction techniques using X-rays, electrons or neutrons. The materials may be in different forms like bulk solid, thin films or powders and need to be observed using microscopes. Finally the properties can be correlated to electronic structure which can be deciphered through various spectroscopy techniques. Magnetic measurements give the insight in to electron-electron correlation. The advantages and limitations of the techniques are also spelled out. In other words, this book takes into account the unaddressed needs of students and teachers associated with the experimental methods. Its relevance has increased manifold, as it addresses a wide scope of the topics in concise manner. Such as‚ improving signal-to-noise ratio, cryogenic methods, vacuum science, sources and detectors for electrons, photons (from infra-red to gamma rays), error analysis, statistical handling of data, etc. Please note: This title is co-published with Capital Publishers, New Delhi.

Book Description
In recent years, optical properties of the unique atomic and molecular structures of materials have drawn great scientific interest. Linear optical properties of materials such as metals, metal oxides, magnetic oxides, and organic materials are based on energy transfer and find applications in wastewater treatment, forensic science, biomedical science, photovoltaics, nuclear technology, and LED displays. Nonlinear optical properties of materials are based on the nonlinear medium and find more advanced applications in frequency mixing generations and optical parametric oscillations. This book presents the underlying principles, implementation, and applications of the linear and nonlinear optical properties of materials and has been divided into two parts emphasizing these properties. The first part of the book, Linear Optics, discusses bimetallic nanoparticles in dielectric media and their integration to dye molecules to detect trace amounts of heavy metals at the nanometer level, as well as to enhance luminescence and image contrasts in forensic inspection and biomedical diagnosis. It shows how the integration of bimetallic nanoparticles into a ZnO matrix promotes broadening of the absorption spectrum from the ultraviolet to the visible wavelength. It explains the role of surface adsorption and photocatalytic degradation in dye-removal kinetics by Fe3O4 magnetic nanoparticles under pulsed white light. It also discusses the double-layer shielding tank design to safely store radioactive waste and photon propagation through the multilayer structures of a human tissue model. The second part of the book, Nonlinear Optics, presents general concepts such as electromagnetic theory, nonlinear medium, and wave propagation, as well as more advanced concepts such as second harmonic generation, phase matching, optical parametric interactions, different frequency generation, sum frequency generation, tunable laser, and optical resonant oscillator.

Book Description
Electron Microscopy and Analysis 1997 celebrates the centenary anniversary of the discovery of the electron by J.J. Thomson in Cambridge and the fiftieth anniversary of this distinguished Institute group. The book includes papers on the early history of electron microscopy (from P. Hawkes), the development of the scanning electron microscope at Cambridge (from K. Smith), electron energy loss spectroscopy (from L.M. Brown), imaging methods (from J. Spence), and the future of electron microscopy (from C. Humphreys). Covering a wide range of applications of advanced techniques, it discusses electron imaging, electron energy-loss and x-ray analysis, and scanning probe and electron beam microscopies. This volume is a handy reference for professionals using microscopes in all areas of physics, materials science, metallurgy, and surface science to gain an overview of developments in our understanding of materials microstructure and of advances in microscope interrogation techniques.

Book Description
This book provides fundamental knowledge in the fields of attosecond science and free electron lasers, based on the insight that the further development of both disciplines can greatly benefit from mutual exposure and interaction between the two communities. With respect to the interaction of high intensity lasers with matter, it covers ultrafast lasers, high-harmonic generation, attosecond pulse generation and characterization. Other chapters review strong-field physics, free electron lasers and experimental instrumentation. Written in an easy accessible style, the book is aimed at graduate and postgraduate students so as to support the scientific training of early stage researchers in this emerging field. Special emphasis is placed on the practical approach of building experiments, allowing young researchers to develop a wide range of scientific skills in order to accelerate the development of spectroscopic techniques and their implementation in scientific experiments. The editors are managers of a research network devoted to the education of young scientists, and this book idea is based on a summer school organized by the ATTOFEL network.
