Available in PDF, EPUB and Kindle. Book excerpt: Colloidal self-assembly promises to be an elegant and efficient route to the bottom-up fabrication of 3-dimensional structures. Programming hierarchical schemes for colloid self-assembly has the potential to widen structural diversity and mimic biological complexity. However, it remains a grand challenge to bridge hierarchies of multiple length- and time-scales associated with the structure and dynamics along complex self-assembly pathways. This thesis employs a variety of computational techniques to address this challenge in silico, programming colloidal self-assembly for structural hierarchy in close connection with contemporary experimental research. In a series of studies, the self-assembly of designer charge-stabilised colloidal magnetic particles into a number of supracolloidal polyhedra for size-selected clusters is demonstrated. The design space supports self-assembled polyhedra of very different morphologies, namely tubular and hollow spheroidal structures, for which the dominant pathways for self-assembly are elucidated, revealing two distinct mechanisms. Here, it is found that for a staged assembly pathway the structure, which derives the strongest energetic stability from the first stage and the weakest from the second stage, is most kinetically accessible. Stemming from these findings, a generic design principle exploiting a hierarchy of interaction strengths is introduced. This design principle is subsequently employed to demonstrate the hierarchical self-assembly of triblock patchy colloidal particles into a variety of colloidal crystals. Furthermore, this design framework exhibits a novel bottom-up route to the fabrication of cubic diamond colloidal crystals, which until recently, have remained elusive.

Available in PDF, EPUB and Kindle. Book excerpt: Self-assembly, the non-dissipative spontaneous formation of structural order spans many length scales, from amphiphilic molecules forming micelles to stars forming galaxies. This thesis mainly deals with systems on the colloidal length scale where the size of a particle is between a nanometer and a micrometer. As such, this thesis focuses on the self-assembly of colloidal particles made in the laboratory forming supracolloidal structures in a capillary and making the link to proteins forming complexes or virus shells. Whereas retrosynthetic analysis gives a handle on how atoms form molecules and subsequently how molecules form even bigger molecules, similar design principles are lacking for assembling micrometer particles. Last decade has witnessed great advances in the synthesis of micrometer particle building blocks. It is currently possible to make colloids anisotropic in shape, or anisotropic in surface properties, so-called patchy particles. Patchy particles show great promise in the design of new building blocks, possibly applicable in novel functional materials. Moreover, patchy particles have also shown to be good models for globular proteins. This thesis discusses mainly two topics using advanced computer simulation techniques. The first part of this thesis deals with the extraction of an effective potential for anisotropic colloidal dumbbell particles interacting through the critical Casimir force. The second part deals with how the kinetics and mechanism of formation of simple colloidal or protein structures are influenced by changing the interaction between or the dynamics of patchy particles.

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: 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 Polymer POSS Nanocomposites and Hybrid Materials written by Susheel Kalia and published by Springer. This book was released on 2018-11-27 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of polymer nanocomposites and hybrid materials with polyhedral oligomeric silsesquioxanes (POSS). Among inorganic nanoparticles, functionalized POSS are unique nano-building blocks that can be used to create a wide variety of hybrid and composite materials, where precise control of nanostructures and properties is required. This book describes the influence of incorporation of POSS moieties into (organic) polymer matrices on the mechanical, thermal and flammability behavior of composites and hybrid organic-inorganic materials. Importantly, POSS-containing materials can be bio-functionalized by linking e.g. peptides and growth factors through appropriate surface modification in order to enhance the haemo-compatibility of cardiovascular devices made of these materials. This volume includes descriptions of synthesis routes of POSS and POSS-containing polymeric materials (e.g. based on polyolefines, epoxy resins and polyurethanes), presentation of POSS’ role as flame retardants and as biocompatible linker, as well as the depiction of decomposition and ageing processes.

Download or read book Flowing Matter written by Federico Toschi and published by Springer Nature. This book was released on 2019-09-25 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: This open access book, published in the Soft and Biological Matter series, presents an introduction to selected research topics in the broad field of flowing matter, including the dynamics of fluids with a complex internal structure -from nematic fluids to soft glasses- as well as active matter and turbulent phenomena. Flowing matter is a subject at the crossroads between physics, mathematics, chemistry, engineering, biology and earth sciences, and relies on a multidisciplinary approach to describe the emergence of the macroscopic behaviours in a system from the coordinated dynamics of its microscopic constituents. Depending on the microscopic interactions, an assembly of molecules or of mesoscopic particles can flow like a simple Newtonian fluid, deform elastically like a solid or behave in a complex manner. When the internal constituents are active, as for biological entities, one generally observes complex large-scale collective motions. Phenomenology is further complicated by the invariable tendency of fluids to display chaos at the large scales or when stirred strongly enough. This volume presents several research topics that address these phenomena encompassing the traditional micro-, meso-, and macro-scales descriptions, and contributes to our understanding of the fundamentals of flowing matter. This book is the legacy of the COST Action MP1305 “Flowing Matter”.
