The study of nanomaterials in a liquid environment can provide insight to processes and dynamics with applications to energy storage materials, catalysis, nanomaterial growth and biological structures. For these applications we have developed techniques for the use of a dedicated in situ fluid holder in combination with aberration corrected scanning transmission electron microscopy (STEM) and dynamic transmission electron microscopy for imaging nanomaterials at atomic-scale resolution within a fluid layer. The abilities of the in situ fluid holder for STEM have been tested by comparing the SiN window thicknesses to optimize imaging conditions and the use electron energy loss spectroscopy to accurately measure the fluid path length within the cell and provide chemical analysis. The imaging artifacts caused by the high energy scanning electron beam have been investigated to determine the causes of bubbling, contamination and charging within the fluid cell for strategies to mitigate these effects. The use of the DTEM has demonstrated the growth of lead sulfide nanoparticles from a precursor solution by the sample drive laser separate from the imaging electrons. These techniques present the ideal platform for future studies of biological structures and dynamics at physiological conditions under low dose imaging with high temporal and spatial resolution.

This text is a companion volume to Transmission Electron Microscopy: A Textbook for Materials Science by Williams and Carter. The aim is to extend the discussion of certain topics that are either rapidly changing at this time or that would benefit from more detailed discussion than space allowed in the primary text. World-renowned researchers have contributed chapters in their area of expertise, and the editors have carefully prepared these chapters to provide a uniform tone and treatment for this exciting material. The book features an unparalleled collection of color figures showcasing the quality and variety of chemical data that can be obtained from today’s instruments, as well as key pitfalls to avoid. As with the previous TEM text, each chapter contains two sets of questions, one for self assessment and a second more suitable for homework assignments. Throughout the book, the style follows that of Williams & Carter even when the subject matter becomes challenging—the aim is always to make the topic understandable by first-year graduate students and others who are working in the field of Materials Science Topics covered include sources, in-situ experiments, electron diffraction, Digital Micrograph, waves and holography, focal-series reconstruction and direct methods, STEM and tomography, energy-filtered TEM (EFTEM) imaging, and spectrum imaging. The range and depth of material makes this companion volume essential reading for the budding microscopist and a key reference for practicing researchers using these and related techniques.

The goal of this book is to provide a general overview of the rapidly developing field of novel scanning probe microscopy (SPM) techniques for characterization of a wide range of functional materials, including complex oxides, biopolymers, and semiconductors. Many recent advances in condensed matter physics and materials science, including transport mechanisms in carbon nanostructures and the role of disorder on high temperature superconductivity, would have been impossible without SPM. The unique aspect of SPM is its potential for imaging functional properties of materials as opposed to structural characterization by electron microscopy. Examples include electrical transport and magnetic, optical, and electromechanical properties. By bringing together critical reviews by leading researchers on the application of SPM to to the nanoscale characterization of functional materials properties, this book provides insight into fundamental and technological advances and future trends in key areas of nanoscience and nanotechnology.

Chemical Imaging Analysis covers the advancements made over the last 50 years in chemical imaging analysis, including different analytical techniques and the ways they were developed and refined to link the composition and structure of manmade and natural materials at the nano/micro scale to the functional behavior at the macroscopic scale. In a development process that started in the early 1960s, a variety of specialized analytical techniques was developed – or adapted from existing techniques – and these techniques have matured into versatile and powerful tools for visualizing structural and compositional heterogeneity. This text explores that journey, providing a general overview of imaging techniques in diverse fields, including mass spectrometry, optical spectrometry including X-rays, electron microscopy, and beam techniques. Provides comprehensive coverage of analytical techniques used in chemical imaging analysis Explores a variety of specialized techniques Provides a general overview of imaging techniques in diverse fields

The advances and technical improvements of X-ray imaging techniques, taking advantage of X-ray focussing optics and high intensity synchrotron sources, nowadays allow for the use of X-rays to probe the cellular nanoscale. Importantly, X-rays permit thick samples to be imaged without sectioning or slicing. In this work, two macromolecules, namely keratin intermediate filament (IF) proteins and DNA, both essential components of cells, were studied by X-ray techniques. Keratin IF proteins make up an integral part of the cytoskeleton of epithelial cells and form a dense intracellular network of bundles. This network is built from monomers in a hierarchical fashion. Thus, the keratin structure formation spans a large range of length scales from a few nanometres (monomers) to micrometres (networks). Here, keratin was studied at three different scales: i) filaments, ii) bundles and iii) networks. Solution small-angle X-ray scattering revealed distinct structural and organisational characteristics of these highly charged polyelectrolyte filaments, such as increasing radius with increasing salt concentration and spatial accumulation of ions depending on the salt concentration. The results are quantified by employing advanced modelling of keratin IFs by a core cylinder fl anked with Gaussian chains. Scanning micro- diffraction was used to study keratin at the bundle scale. Very different morphologies of keratin bundles were observed at different salt conditions. At the network scale, new imaging approaches and analyses were applied to the study of whole cells. Ptychography and scanning X-ray nano-diffraction imaging were performed on the same cells, allowing for high resolution in real and reciprocal space, thereby revealing the internal structure of these networks. By using a fitting routine based on simulations of IFs packed on a hexagonal lattice, the radius of each fi lament and distance between fi laments were retrieved. In mammalian cells, each nucleus contains 2 nm-thick DNA double helices with a total length of about 2 m. The DNA strands are packed in a highly hierarchical manner into individual chromosomes. DNA was studied in intact cells by visible light microscopy and scanning X-ray nano-diffraction, unveiling the compaction und decompaction of DNA during the cell cycle. Thus, we obtained information on the aggregation state of the nuclear DNA at a real space resolution on the order of few hundreds nm. To exploit to the reciprocal space information, individual diffraction patterns were analysed according to a generalised Porod’s law at a resolution down to 10 nm. We were able to distinguish nucleoli, heterochromatin and euchromatin in the nuclei and follow the compaction and decompaction during the cell division cycle.
