Available in PDF, EPUB and Kindle. Book excerpt: The synthesis and assembly of anisometric colloids (500 nm to ~2 [mu]m) have attracted recent interest from both a fundamental, as well as a technological standpoint. Computational simulations predict that these building blocks are capable of forming structures considerably more complex than those of their spherical counterparts. At the same time, emerging studies indicate that the resulting assemblies can possess striking properties such as negative refraction, despite the tendency for these materials to exhibit only partial order. In this dissertation, I describe our efforts to understand how specific colloidal features on a single particle level can lead to a significant impact on their selfassembly behavior. One aspect of this work is the synthesis of a class of nonspherical core-shell and hollow particles, which can be directed into new colloidal phases by shape programming alone, by optical manipulation, or by magnetic fields. With these colloids as a platform, a number of unusual structures were then studied under confinement via real-time optical microscopy and videography. Using hard peanut-shaped silica shells, we directly observed a 2D aperiodic 'degenerate crystal', described only in simulations to date. In this phase each of the constituent particle lobes occupies a triangular lattice site, while the dimer axes orient along one of the three underlying crystalline directions. Remarkably, we illustrate that an oblique crystal with orientational order can assemble instead, when hematite-silica core-shell particles with the exact same shape are used. In this case, the canted antiferromagnetism of the core hematite, in conjunction with the hierarchical colloidal microstructure, produces a permanent transverse magnetic dipole in the dimers. This has the effect of introducing attractive dipolar forces to the interparticle potential. We also explored the structures formed by mildly-fused polystyrene-silica asymmetric dimers confined to gap heights intermediate to the in-plane monolayer and the out-ofplane monolayer. The system was found to evolve from a 2D (planar) oblique phase to a quasi-2D rotator, and finally to a 2D (upright) hexagonally-close-packed crystal. These studies highlight the rich phase behavior of complex dispersions, and show promise for diverse colloidal structures to be formed using simple self-assembly approaches to condense the systems.

Download or read book Synthesis and Characterization of Anisotropic Colloidal Particles written by Martin Hoffmann and published by Logos Verlag Berlin. This book was released on 2010 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Anisotropic colloids differ from isotropic particles as they may combine a non-spherical shape with a heterogeneous composition or surface chemistry. These versatile colloids have moved into the focus of various research groups in the fields of chemistry and physics. Hence, preparation pathways for novel model systems and their characterization are challenging aspects in fundamental research and material science. In the first part of this work, the author describes the synthesis and characterization of two colloidal systems with dumbbell-shaped core-shell morphology. The core consists of poly(methyl methacrylate) and poly(styrene). As a special feature, the attached shell layer promotes the change of the particle size and the aspect ratio by simply changing the ionic strength or temperature. Depolarized dynamic light scattering (DDLS) was used to investigate how these stimuli affect the translational and the rotational diffusion in the highly diluted state. The hydrodynamics of the particles could be well described with stick-boundary conditions by using analytical expressions for a double sphere, prolate ellipsoid and cylinder or the shell model, respectively. Electron and scanning force microscopy were applied to image the particle morphology in real space. The second part is devoted to the hydrodynamics of monodisperse, submicron-sized colloidal clusters, which consist of one to four spherical building blocks. The author demonstrates that the shell model is an excellent tool to identify the rotational relaxations which are accessible by DDLS.

This book was released on 2020-11-04 with total page 102 pages. Available in PDF, EPUB and Kindle. Book excerpt: Top-down approaches are currently the main contributor of fabricating microelectronic devices. However, the prohibitive cost of numerous technological steps in these approaches is the main obstacle to further progress. Furthermore, a large number of applications necessitate fabrication of complex and ultra-small devices that cannot be made using these approaches. New approaches based on natural self-assembly of matter need to be developed to allow for fabrication of micro and nanoelectronic devices. Self-assembly of nanostructures is a dynamic field, which explores physics of these structures and new ways to fabricate them. However, the major problem is how to control the properties of the nanostructures resulting from low dimensionality. This book presents recent advances made to address this problem, and fabricate nanostructures using self-assembly.

Available in PDF, EPUB and Kindle. Book excerpt: Noble metal nanoparticles have attracted enormous scientific and technological interest because of their unique optical properties, which are related to surface plasmon resonances. The interest in nanosized metal particles dates back to ancient societies, when metals were used in various forms as decorative elements. From the famous Lycurgus cup, made by the Romans in the 4th century AD, through thousands of stained glasses in churches and cathedrals all over medieval Europe, bright-yellow, green, or red colors have been obtained by a touch of metallic additions during glass blowing. This peculiar interaction of light with nanometals can be widely tuned through the morphology and assembly of nanoparticles, thereby expanding the range of potential applications, from energy and information storage to biomedicine, including novel diagnostic and therapeutic methods. This book compiles recent developments that clearly illustrate the state of the art in this cutting-edge research field. It comprises different review articles written by the teams of Prof. Luis Liz-Marzán, an international leader in chemical nanotechnology who has made seminal contributions to the use of colloid chemistry methods to understand and tailor the growth of metal particles at the nanoscale. Apart from synthesis, the book also describes in detail the plasmonic properties of nanomaterials and illustrates some representative applications. This book will appeal to anyone involved in nanotechnology, nanocrystal growth, nanoplasmonics, and surface-enhanced spectroscopies.

Book excerpt: In this book anisotropic one-dimensional and two-dimensional nanoscale building blocks and their assembly into fascinating and qualitatively new functional structures embracing both hard and soft components are explained. Contributions from leading experts regarding important aspects like synthesis, assembly, properties and applications of the above materials are compiled into a reference book. The anisotropy, i.e. the direction-dependent physical properties, of materials is fascinating and elegant and has sparked the quest for anisotropic materials with useful properties. With such a curiosity, material scientists have ventured into the realm of nanometer length scale and have explored the anisotropic nanoscale building blocks such as metallic and nonmetallic particles as well as organic molecular aggregates. It turns out that the anisotropic nanoscale building blocks, in addition to direction-dependent properties, exhibit dimension and morphology dependence of physical properties. Moreover, ordered arrays of anisotropic nanoscale building blocks furnish novel properties into the resulting system which would be entirely different from the properties of individual ones. Undoubtedly, these promising properties have qualified them as enabling building blocks of 21st century materials science, nanoscience and nanotechnology. Readers will find this book professionally valuable and intellectually stimulating in the rapidly emerging area of anisotropic nanomaterials.
