High-Resolution Electron Microscopy
This book covers both practical and theoretical aspects of atomic resolution transmission electron microscopy. The discovery of the carbon nanotube, the three-dimensional imaging of the ribosome, and the imaging of a single foreign atom inside a thin crystal by energy-filtered transmission electron microscopy have all demonstrated the immense power of this technique. The recent development of aberration-correction devices has brought the spatial resolution of the method below one Angstrom. The emphasis throughout is on a clear presentation of fundamental concepts, and practical advice. The chapters review simple electron optics, phase contrast theory, coherence theory, and imaging theory for thin crystals. The multiple scattering theory is given in full, and the relationship between the various formulations (Bloch-wave, multislice, scattering matrix, Howie–Whelan equations, phase grating etc) is explained. Applications in biology and materials science are covered, with discussions of radiation damage, sample preparation, image processing and super-resolution, electron holography, and aberration correction. The theory of high-angle annular dark field Z-contrast imaging by scanning transmission electron microscopy is given in full. Additional chapters are devoted to electron sources and detectors, fault diagnosis, experimental methods and associated techniques such as channelling effects in X-ray microanalysis, microdiffraction, cathodoluminescence, environmental microscopy and electron energy-loss spectroscopy.

Bioactive silicon nitride: A new therapeutic material for osteoarthropathy
While the reciprocity between bioceramics and living cells is complex, it is principally governed by the implant’s surface chemistry. Consequently, a deeper understanding of the chemical interactions of bioceramics with living tissue could ultimately lead to new therapeutic strategies. However, the physical and chemical principles that govern these interactions remain unclear. The intricacies of this biological synergy are explored within this paper by examining the peculiar surface chemistry of a relatively new bioceramic, silicon nitride (Si

influences cellular signal transduction functions and differentiation mechanisms. In other words, we interpret its reciprocity with living cells in chemical terms. These new findings suggest that Si

Recent Advances in Electron Tomography: TEM and HAADF-STEM Tomography for Materials Science and Semiconductor Applications
Electron tomography is a well-established technique for
three-dimensional structure determination of (almost) amorphous specimens
in life sciences applications. With the recent advances in nanotechnology
and the semiconductor industry, there is also an increasing need for
high-resolution three-dimensional (3D) structural information in physical
sciences. In this article, we evaluate the capabilities and limitations of
transmission electron microscopy (TEM) and high-angle-annular-dark-field
scanning transmission electron microscopy (HAADF-STEM) tomography for the
3D structural characterization of partially crystalline to highly
crystalline materials. Our analysis of catalysts, a hydrogen storage
material, and different semiconductor devices shows that features with a
diameter as small as 1–2 nm can be resolved in three dimensions by
electron tomography. For partially crystalline materials with small single
crystalline domains, bright-field TEM tomography provides reliable 3D
structural information. HAADF-STEM tomography is more versatile and can
also be used for high-resolution 3D imaging of highly crystalline
materials such as semiconductor devices.

Microstructural design of advanced engineering materials
The choice of a material for a certain application is made taking into account its properties.If, for example one would like to produce a table, a hard material is needed to guarantee the stability of the product, but the material should not be too hard so that manufacturing is still as easy as possible - in this simple example wood might be.
