Book Description
Scanning Transmission Electron Microscopy is focused on discussing the latest approaches in the recording of high-fidelity quantitative annular dark-field (ADF) data. It showcases the application of machine learning in electron microscopy and the latest advancements in image processing and data interpretation for materials notoriously difficult to analyze using scanning transmission electron microscopy (STEM). It also highlights strategies to record and interpret large electron diffraction datasets for the analysis of nanostructures. This book: Discusses existing approaches for experimental design in the recording of high-fidelity quantitative ADF data Presents the most common types of scintillator-photomultiplier ADF detectors, along with their strengths and weaknesses. Proposes strategies to minimize the introduction of errors from these detectors and avenues for dealing with residual errors Discusses the practice of reliable multiframe imaging, along with the benefits and new experimental opportunities it presents in electron dose or dose-rate management Focuses on supervised and unsupervised machine learning for electron microscopy Discusses open data formats, community-driven software, and data repositories Proposes methods to process information at both global and local scales, and discusses avenues to improve the storage, transfer, analysis, and interpretation of multidimensional datasets Provides the spectrum of possibilities to study materials at the resolution limit by means of new developments in instrumentation Recommends methods for quantitative structural characterization of sensitive nanomaterials using electron diffraction techniques and describes strategies to collect electron diffraction patterns for such materials This book helps academics, researchers, and industry professionals in materials science, chemistry, physics, and related fields to understand and apply computer-science–derived analysis methods to solve problems regarding data analysis and interpretation of materials properties.

Book Description
Research in noble metal nanoparticles has led to exciting progress in a versatile array of applications. For the purpose of better tailoring of nanoparticles activities and understanding the correlation between their structures and properties, control over the composition, shape, size and architecture of bimetallic and multimetallic nanomaterials plays an important role on revealing their new or enhanced functions for potentials application. Advance electron microscopy techniques were used to provide atomic scale insights into the structure-properties of different materials: PtPd, Au-Au 3 Cu, Cu-Pt, AgPd/Pt and AuCu/Pt nanoparticles. The objective of this work is to understand the physical and chemical properties of nanomaterials and describe synthesis, characterization, surface properties and growth mechanism of various bimetallic and multimetallic nanoparticles. The findings have provided us with novel and significant insights into the physical and chemical properties of noble metal nanoparticles. Different synthesis routes allowed us to synthesize bimetallic: Pt-Pd, Au-Au 3 Cu, Cu-Pt and trimetallic: AgPd/Pt, AuCu/Pt, core-shell and alloyed nanoparticles with monodispersed sizes, controlled shapes and tunable surface properties. For example, we have synthesized the polyhedral PtPd core-shell nanoparticles with octahedral, decahedral, and triangular plates. Decahedral PtPd core-shell structures are novel morphologies for this system. For the first time we fabricated that the Au core and Au 3 Cu alloyed shell nanoparticles passivated with CuS2 surface layers and characterized by Cs-corrected scanning transmission electron microscopy. The analysis of the high-resolution micrographs reveals that these nanoparticles have decahedral structure with shell periodicity, and that each of the particles is composed by Au core and Au 3 Cu ordered superlattice alloyed shell surrounded by CuS 2 surface layer. Additionally, we have described both experimental and theoretical methods of synthesis and growth mechanism of highly monodispersed Cu-Pt nanoclusters. The advance electron microscopy of microanalysis allowed us to study the distribution of Cu and Pt with atomistic resolution. The microanalysis revealed that Pt is embedded randomly in the Cu lattice. A novel grand canonical - Langevin dynamics simulation showed the formation of alloy structures in good agreement with the experimental evidence. Finally, we demonstrated the synthesis of AgPd-Pt trimetallic nanoparticles with two different morphologies: multiply twinned core-shell, and hollow particles. We also investigated the growth mechanism of the nanoparticles using grand canonical-Monte Carlo simulations. We found that the Pt regions grow at overpotentials on the AgPd nanoalloys, forming 3D islands at the early stages of the deposition process and presenting very good agreement between the simulated structures and those observed experimentally. Similarly, we also investigated AuCu/Pt core-shell trimetallic nanoparticles, presenting new way to control the nanoparticles morphologies due to the presence of third metal (Pt). Where, we observed the Pt layers are overgrowth on the as prepared AuCu core by Frank-van der Merwe (FM) and Stranski-Krastanov (SK) growth modes. In addition, these nanostructure presents high index facet surfaces with {211} and (321} families, that are highly open structure surfaces and interesting for the catalytic applications. The results of these studies will be useful for the future applications and the design of advanced functional nanomaterials.
