The characteristics of nanoparticles, such as their size, shape, surface morphology, crystal structure, grain boundaries, and composition, can be tuned to match the intended use. Thus, the design of nanostructured materials with a wide range of applications in the engineering, chemistry, physics, ceramics, biotechnology, biomedicine, and environmental fields represents an active area of research. Nanostructured materials are now widely used in research and industry, and their particular properties enable advanced physicochemical, electrical, thermal, catalytic, coloristic, optical, and magnetic applications.The present Special Issue aims to provide a comprehensive overview of original research articles, communications, and reviews that focus on the development, characterization, and/or applications of nanoparticles and their composites.

Polyoxometalates (POMs) are a large and rapidly growing class of early-transition-metal oxide clusters. POMs are formed via acid-involved condensation reactions from monomeric oxometalate units, thus holding a special position (intermediate state) between monomeric oxometalate units and infinite metal oxide frameworks. POMs continue to show remarkable advances and unexpected surprises in both their fundamentals and applications. The chemical compositions (addenda atoms) of POMs are mainly Mo, W, V, Nb, and Ta, and the heteroatoms of POMs are more variable, including P, As, B, Al, Si, Ge, S, and so on. The wide range of chemical composition variability and the large amount of unusual structural types enable POMs to exhibit a large number of different properties, such as rich solution equilibria, significant chemical and thermal stability, strong acidity, and the ability to act as proton-electron sinks due to their fast and reversible proton-coupled redox processes. Based on their intrinsic multifunctional nature, POMs have significant applications in catalysis, medicine, and materials science, etc. POMs not only can be used widely in different disciplines but can also be combined with polymers, oxides, ionic liquids, or carbonaceous supports to construct new and advanced composite (hybrid) materials, which have important, extensive applications in catalysis, electrode materials, electrocatalysis, photocatalysis, and so on.

The use of polymer thin films is currently implemented in almost every aspect of modern life due to their cost-efficiency, lightness, flexibility, and unique physical and chemical properties. The reason for focusing research into polymer thin films is to understand their thermodynamic and kinetic mechanisms, such as interfacial interactions, flow behavior, film formation, relationships between deposition process parameters and the film structure, and other advanced functional properties. Thin polymer film research focuses on a wide range of industrial applications, including energy technologies, optics, sensors, microelectronics, medicine, biotechnology, etc.This Special Issue highlights and discusses studies on the formation of polymer films, their morphological analysis, and their use in various applications, including sensors, antifouling coatings, and coatings for harnessing solar energy. In addition, this Special Issue also includes two review papers on the latest research on polymer-waveguide-based optical sensors and the integration of antifouling and anti-cavitation coatings on propellers.

As an important unit operation, crystallization is a process in which nucleation, growth, agglomeration, and breakage are regulated to produce high-quality crystals and achieve efficient separation as well as purification. Since a crystallization process often presents the characteristics of strong coupling, nonlinearity, and large lagging, it is a challenge to rationally design a robust, well-characterized process to efficiently crystallize and prepare a high-quality crystalline product. The development of process analytical technology that can provide fast and accurate inline or online measurement is of great importance in the design and control of crystallization processes. Simulation technology, e.g., molecular dynamics simulation and hydrodynamics simulation, can provide time- or location-dependent insight into the process on multiple scales. These experimental and simulation tools can greatly help to further investigate crystallization processes. This Special Issue served to provide a platform for researchers to report results and findings in crystallization process technologies, simulation and process analytical technologies, and relevant crystallization studies.

The series Topics in Current Chemistry Collections presents critical reviews from the journal Topics in Current Chemistry organized in topical volumes. The scope of coverage is all areas of chemical science including the interfaces with related disciplines such as biology, medicine and materials science. The goal of each thematic volume is to give the non-specialist reader, whether in academia or industry, a comprehensive insight into an area where new research is emerging which is of interest to a larger scientific audience.Each review within the volume critically surveys one aspect of that topic and places it within the context of the volume as a whole. The most significant developments of the last 5 to 10 years are presented using selected examples to illustrate the principles discussed. The coverage is not intended to be an exhaustive summary of the field or include large quantities of data, but should rather be conceptual, concentrating on the methodological thinking that will allow the non-specialist reader to understand the information presented. Contributions also offer an outlook on potential future developments in the field.Chapters "e;Metal Peptide Conjugates in Cell and Tissue Imaging and Biosensing"e;, "e;Luminescent Metal Complexes as Emerging Tools for Lipid Imaging"e; and "e;Determination and Imaging of Small Biomolecules and Ions Using Ruthenium(II) Complex Based Chemosensors"e; are available open access under a CC BY 4.0 License via link.springer.com.

This book describes a detailed multi-scale approach integrating nano- (active site), meso- (porous catalyst architecture) and macroscale (reactor) efforts, to address the challenges of producing a better epoxidation catalyst. It contains an in-depth study of the design and synthesis of gold nanoparticles and their application as a catalyst for direct gas phase propylene epoxidation. "e;Direct"e; means using only hydrogen and oxygen in one step, which is key for sustainable manufacturing, as opposed to commercialised, more complex production routes requiring multiple steps, or integration with another chemical plant. The insights gained can be used for rational design for stable and selective catalysts for other reactions. It also details the step-by-step process to build an epoxidation reactor system with a focus on safety aspects, which can be used as a guidebook for undergraduate and graduate students in chemical engineering. Beyond heterogeneous catalysis, the new, easily accomplished methodology for synthesising atomically precise nanoparticles is shown to be relevant to electrocatalysis and to healthcare applications, such as anti-microbial surfaces.This book will be of interest to researchers, engineers and experts in the related areas of chemical engineering, chemistry, material science and electrochemistry.
