This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Ultrasmall nanoparticles have seen growing interest in several fields such as medicine, optics, and catalysis due to their unique size-dependent properties. Among these are fluorescent core-shell silica nanoparticles synthesized in water known as Cornell prime dots (C' dots), which are composed of a silica core and a poly(ethylene glycol) (PEG) shell. These C' dots are poised to become promising diagnostic and therapeutic tools in medicine, particularly for cancer applications. While spherical C' dots have already been in FDA-approved human clinical trials, exploration has expanded into different topologies of silica nanoparticles such as rings and cages, providing higher aspect ratios and higher surface area to volume ratios. For clinical translation of such nanostructures, quantitative assessments of their size and size dispersity remain parameters for further investigation and are critical to understanding and evaluating their effectiveness and safety in nanomedicine applications. Here, solution small-angle X-ray scattering was employed to characterize 3D structural details of ring-type silica nanostructures and their size and size dispersity. A hollow cylinder model provided consistent structural and dispersity parameters that were supported by transmission electron microscopy investigations.

Book Synopsis Vertical Evaporative Assembly and Double Replication of Unary and Binary Silica Colloidal Crystal Films by : Jennifer Russell
Download or read book Vertical Evaporative Assembly and Double Replication of Unary and Binary Silica Colloidal Crystal Films written by Jennifer Russell and published by . This book was released on 2017 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: As the field of nanomaterials expands, the pursuit of smaller dimensions necessitates the ability to both synthesize nanoscale building blocks and also control their spatial arrangements. In a size regime where dimensions and structure may dictate material properties, colloidal nanoparticles are versatile nanoscale building blocks with the ability to order into diverse periodic arrangements, called colloidal crystals. There have been tremendous advancements in the area of colloidal crystal fabrication over the past few decades, but new syntheses and assembly techniques continue to develop in order to unite scale and desired material structure. In this dissertation, I describe my work from three different projects: silica binary colloidal crystal assembly, the use of colloidal crystal films in template replication synthesis, and silica nanoparticle morphological changes during assembly. In Chapter 1, I introduce colloidal crystals and review synthetic methods for silica colloid synthesis and techniques for their assembly into colloidal crystals. I also discuss template replication synthesis and provide an overview of the projects detailed in the remaining chapters. I will discuss my first project in Chapter 2, in which the phase behavior of 36 nm and 22 nm silica binary colloidal crystal films was mapped over a range of compositions and temperatures in order to optimize AB2-type binary colloidal crystal film growth. While thermodynamic phase diagrams can serve as a guide in selecting binary systems based on size ratios and what phases are energetically favorable, they do not account for the intricacies of experimental non-equilibrium conditions. Therefore, this systematic experimental approach to determining growth conditions was employed. We found that low temperature (30-35C) film growth and a range of excess 22 nm silica produced the largest, most widespread AB2 domains in film samples. I present the phase mapping results and discuss the possible reasons for the deposition conditions-dependent phase behavior and how it might extend to future binary colloidal crystal film studies. In Chapter 3, I describe double replication of silica colloidal crystal films with the use of contracting polymers. I quantify the lattice contraction of several polymer inverse replicates of the silica colloidal crystal films through the extensive use of electron microscopy. I discuss lattice contraction as a function of colloidal template size and also polymer elastic moduli using AFM nanoindentation. It was discovered in this project that polymer inverse opal lattices re-expand upon filling with inorganic oxide sol gels. This finding negates the use of double replication for shrinking periodic structures with these contracting polymers; but the results are still interesting for double replication methodology and presented evidence of the role of surface energy in the polymer contraction/expansion process. Finally, I extended the method to double replication of binary colloidal crystal film templates of silica nanoparticles

Download or read book Nanoparticle Technology Handbook written by Masuo Hosokawa and published by Elsevier. This book was released on 2007-10-19 with total page 645 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanoparticle technology, which handles the preparation, processing, application and characterisation of nanoparticles, is a new and revolutionary technology. It becomes the core of nanotechnology as an extension of the conventional Fine Particle / Powder Technology. Nanoparticle technology plays an important role in the implementation of nanotechnology in many engineering and industrial fields including electronic devices, advanced ceramics, new batteries, engineered catalysts, functional paint and ink, Drug Delivery System, biotechnology, etc.; and makes use of the unique properties of the nanoparticles which are completely different from those of the bulk materials. This new handbook is the first to explain complete aspects of nanoparticles with many application examples showing their advantages and advanced development. There are handbooks which briefly mention the nanosized particles or their related applications, but no handbook describing the complete aspects of nanoparticles has been published so far. The handbook elucidates of the basic properties of nanoparticles and various nanostructural materials with their characterisation methods in the first part. It also introduces more than 40 examples of practical and potential uses of nanoparticles in the later part dealing with applications. It is intended to give readers a clear picture of nanoparticles as well as new ideas or hints on their applications to create new materials or to improve the performance of the advanced functional materials developed with the nanoparticles. * Introduces all aspects of nanoparticle technology, from the fundamentals to applications. * Includes basic information on the preparation through to the characterization of nanoparticles from various viewpoints * Includes information on nanostructures, which play an important role in practical applications.

Download or read book Characterization of Polymer Blends written by Sabu Thomas and published by John Wiley & Sons. This book was released on 2015-02-09 with total page 972 pages. Available in PDF, EPUB and Kindle. Book excerpt: Filling the gap for a reference dedicated to the characterization of polymer blends and their micro and nano morphologies, this book provides comprehensive, systematic coverage in a one-stop, two-volume resource for all those working in the field. Leading researchers from industry and academia, as well as from government and private research institutions around the world summarize recent technical advances in chapters devoted to their individual contributions. In so doing, they examine a wide range of modern characterization techniques, from microscopy and spectroscopy to diffraction, thermal analysis, rheology, mechanical measurements and chromatography. These methods are compared with each other to assist in determining the best solution for both fundamental and applied problems, paying attention to the characterization of nanoscale miscibility and interfaces, both in blends involving copolymers and in immiscible blends. The thermodynamics, miscibility, phase separation, morphology and interfaces in polymer blends are also discussed in light of new insights involving the nanoscopic scale. Finally, the authors detail the processing-morphology-property relationships of polymer blends, as well as the influence of processing on the generation of micro and nano morphologies, and the dependence of these morphologies on the properties of blends. Hot topics such as compatibilization through nanoparticles, miscibility of new biopolymers and nanoscale investigations of interfaces in blends are also addressed. With its application-oriented approach, handpicked selection of topics and expert contributors, this is an outstanding survey for anyone involved in the field of polymer blends for advanced technologies.
