Download or read book Crystallization of Nanoscaled Colloids written by Philip G. Born. This book was released on 2013-05-23. Available in PDF, EPUB and Kindle. Book excerpt: This thesis deals with the processes that create ordered assemblies from disordered nanoparticles. Ordered packings of nanoscale particles can exhibit unusual properties. This work investigates the self-assembly of such particles, a process widely employed for the generation of ordered structures, but not yet well understood. In situ methods are used to observe the assembly of sub-micron polymer lattices and sub-10 nm gold particles into crystalline monolayers and aggregates. On the basis of these results, the book develops new models that describe the competition between different influences, such as thermal agitation and directional forces. It suggests necessary criteria that lead to the emergence of order.

Book Synopsis Crystallization and Growth of Colloidal Nanocrystals by : Edson Roberto Leite

Download or read book Crystallization and Growth of Colloidal Nanocrystals written by Edson Roberto Leite. This book was released on 2011-11-17. Available in PDF, EPUB and Kindle. Book excerpt: Since the size, shape, and microstructure of nanocrystalline materials strongly impact physical and chemical properties, the development of new synthetic routes to nanocrystals with controlled composition and morphology is a key objective of the nanomaterials community. This objective is dependent on control of the nucleation and growth mechanisms that occur during the synthetic process, which in turn requires a fundamental understanding of both classical nucleation and growth and non-classical growth processes in nanostructured materials. Recently, a novel growth process called Oriented Attachment (OA) was identified which appears to be a fundamental mechanism during the development of nanoscale materials. OA is a special case of aggregation that provides an important route by which nanocrystals grow, defects are formed, and unique—often symmetry-defying—crystal morphologies can be produced. This growth mechanism involves reversible self-assembly of primary nanocrystals followed by reorientation of the assembled nanoparticles to achieve structural accord at the particle-particle interface, the removal of adsorbates and solvent molecules, and, finally, the irreversible formation of chemical bonds to produce new single crystals, twins, and intergrowths. Crystallization and Growth of Colloidal Nanocrystals provides a current understanding of the mechanisms related to nucleation and growth for use in controlling nanocrystal morphology and physical-chemical properties, and is essential reading for any chemist or materials scientist with an interest in using nanocrystals as building blocks for larger structures. This book provides a compendium for the expert reader as well as an excellent introduction for advanced undergraduate and graduate students seeking a gateway into this dynamic area of research.

Book Synopsis Surface Patterning with Colloidal Monolayers by : Nicolas Vogel

Download or read book Surface Patterning with Colloidal Monolayers written by Nicolas Vogel. This book was released on 2012-12-28. Available in PDF, EPUB and Kindle. Book excerpt: How can the two dimensional crystallization of colloids be used to form highly ordered colloidal monolayers on solid substrates? What application does this have in generating arrays of nanostructures? These questions are addressed in Nicolas Vogel's thesis. Vogel describes a simple preparation method for the formation of uniform colloidal crystals over large areas, which he refines to yield more complex binary and non-close-packed arrangements. These monolayers can be applied to a process termed colloidal lithography which is used to prepare high quality metallic nanostructures with tailored properties defined to suit a variety of applications. Moreover, the author describes a method used to create metallic nanodot arrays with a resolution unprecedented for colloidal lithography methods. The author also outlines methodology to embed nanoparticle arrays into the substrate, which is developed and used to design robust, re-usable biosensor platforms and nanoscale patterns of biomimetic lipid bilayer membranes. The research in this thesis has led to a large number of publications in internationally renowned journals.

Download or read book Colloids for Nano- and Biotechnology written by Zoltán Hórvölgyi. This book was released on 2008-10-01. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains a selection of the papers presented at the 9th Conference on Colloid Chemistry. A colloid chemical approach to nano- and biotechnology was one of the main topics of the meeting held in Siófok, Hungary in October 2007. It was organized by the Hungarian Chemical Society in cooperation with leading Hungarian universities and the Hungarian Academy of Sciences. The contributions demonstrated the progress of the field and supported that "The world of neglected dimensions" should not be neglected at all in modern material sciences and technologies. This volume is intended for professionals dealing with fundamental research or development of industrial applications, who encounter colloids, nanostructures, and interfacial phenomena during their work.
