This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "The precise organization of nano-objects into well-defined patterns at surfaces and interfaces is of increasing importance in nanoscience research. Among the existing nanopatterning approaches, molecular self-assembly provides a highly accurate, efficient, and potentially low-cost "bottom-up" route to create complex nano-patterns with immense flexibility in terms of nanoscale building blocks. The structure and functionality of molecular building blocks define the type of interactions that are involved in the formation of the molecular pattern and in the templating process. This Thesis combines the high hierarchical order offered by physisorbed self-assembled molecular networks (SAMNs) and the enhanced stability gained from chemisorbed self-assembled monolayers (SAMs). The result is robust and/or versatile 2D molecular monolayers that can be applied to the template-directed formation of organic and inorganic nanostructures. The first part of this Thesis explores the use of a new tridentate thiol for the formation of SAMs with long-term stability on Au(111). This design is based on a benzene ring substituted with three methylthiol groups in alternation with three alkyl chains. The molecular orientation and long-range order of these SAMs depend on the length of the alkyl chains. Physisorbed SAMN for nanopatterning of gold nanoparticles were prepared using a p-dialkoxybenzene SAMN modified-HOPG substrate. The observed templating effect is based on van der Waals interactions between the alkyl chains of the SAMN and AuNP. The assembly efficiency is greatest when these chains are of similar length.The dynamics of C60 assembly onto SAMs of benzenethiols (BT) and penfluorobenzenthiols (PFBT) were been studied. The electronic properties of these SAMs directly affect the growth kinetic of C60 overlayers. The study of physisorbed [C60]fullerene multicarboxylic acids on an Au (111) substrate identifies the important role of molecule-substrate interactions and the intermolecular hydrogen bonding in the formation of a 2D assembly. The possibility of tuning the molecule-Au interaction was demonstrated using a PFBT-modified Au substrate. The dimensionality of the resulting [C60]fullerene multicarboxylic acids monolayer (1D vs 2D) was shown to depend on the number of malonic acid functionalities present. " --

Download or read book Nanomanufacturing Handbook written by Ahmed Busnaina and published by CRC Press. This book was released on 2017-12-19 with total page 489 pages. Available in PDF, EPUB and Kindle. Book excerpt: Breakthroughs in nanotechnology have been coming at a rapid pace over the past few years. This was fueled by significant worldwide investments by governments and industry. But if these promising young technologies cannot begin to show commercial viability soon, that funding is in danger of disappearing as investors lose their appetites and the economic and scientific promise of nanotechnology may not be realized. Scrutinizing the barriers to commercial scale-up of nanotechnologies, the Nanomanufacturing Handbook presents a broad survey of the research being done to bring nanotechnology out of the laboratory and into the factory. Current research into nanotechnology focuses on the underlying science, but as this forward-looking handbook points out, the immediate need is for research into scale-up, process robustness, and system integration issues. Taking that message to heart, this book collects cutting-edge research from top experts who examine such topics as surface-programmed assembly, fabrication and applications of single-walled carbon nanotubes (SWNTs) including nanoelectronics, manufacturing nanoelectrical contacts, room-temperature nanoimprint and nanocontact technologies, nanocontacts and switch reliability, defects and surface preparation, and other innovative, application-driven initiatives. In addition to these technical issues, the author provides a survey of the current state of nanomanufacturing in the United States—the first of its kind—and coverage also reaches into patenting nanotechnologies as well as regulatory and societal issues. With timely, authoritative coverage accompanied by numerous illustrations, the Nanomanufacturing Handbook clarifies the current challenges facing industrial-scale nanotechnologies and outlines advanced tools and strategies that will help overcome them.

Download or read book Simulation and Control of Dynamic Directed Self assembly of Nanostructures written by Sivaraman Ramaswamy and published by . This book was released on 2015 with total page 117 pages. Available in PDF, EPUB and Kindle. Book excerpt: Self-assembled nanoscale structures are the basis for various technological advancements in functional materials, sensors, and molecular circuits and factories. With significant progress in self-assembly of periodic nanostructures (such as monolayers), the focus is now shifting towards non-periodic structures. Control of various interaction force fields (electrostatic, Van der Waals, etc.) between the nanoparticles and external controls can result in the formation of nanostructures with desired geometry. The aim is to design the nanoparticles and the external actuators such that the desired structure can be self-assembled rapidly with high reliability and avoiding any kinetic trapping that an ill-designed energy landscape might cause. Deterministic dynamic modeling of such self-assembled nanostructures, directed by external fields, through a Master Equation approach, leads to a set of differential equations of such large size that even the most efficient solution algorithms are overwhelmed. Thus, model reduction is a key necessity. This thesis presents a methodological approach and specific algorithms, which generate time-varying, reduced-order models for the description of directed self-assembly of nanoparticles by external fields. The approach is based on Finite State Projection and is adaptive, i.e., it generates reduced-order models that vary over time. The algorithm uses event-detection concepts to determine automatically, during simulation, suitable time points at which the projection space and thus the structure of the reduced-order model change, in such a way that the computational load remains low while the upper bound on the simulation error, resulting from model reduction, is lower than a prescribed maximum limit. The thesis also presents an optimal control strategy that can guide any initial random configuration of nanoparticles to a final structure of desired geometry, in minimum time. It employs a multi-resolution view of the dynamically evolving configurations of nanoparticles, which are described through the simulation methodology described before. External charges, attracting or repelling the nanoparticles, are the controls, whose location and intensity are determined by the optimality conditions of the optimal control strategy. To ensure analytic consistency of the parametric sensitivities, during the computation of the optimal controls, and thus guarantee the optimality of the resulting control policy, a priori determination of enlarged constant projection spaces is shown to be essential. The thesis also presents a series of case studies, which illustrate how the proposed methods can be used to simulate effectively directed self-assembly of an appreciable number of nanoparticles, and reach the desired geometry. These case studies also illuminate several of its features, such as: superiority over a static optimal solution; evasion of kinetic traps; and effective handling of combinatorial complications arising for systems with large-size domains and many particles.

Download or read book Nanoscale Assembly written by Wilhelm T.S. Huck and published by Springer Science & Business Media. This book was released on 2006-07-11 with total page 249 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology has received tremendous interest over the last decade, not only from the scientific community but also from a business perspective and from the general public. Although nanotechnology is still at the largely unexplored frontier of science, it has the potential for extremely exciting technological innovations that will have an enormous impact on areas as diverse as information technology, medicine, energy supply and probably many others. The miniturization of devices and structures will impact the speed of devices and information storage capacity. More importantly, though, nanotechnology should lead to completely new functional devices as nanostructures have fundamentally different physical properties that are governed by quantum effects. When nanometer sized features are fabricated in materials that are currently used in electronic, magnetic, and optical applications, quantum behavior will lead to a set of unprecedented properties. The interactions of nanostructures with biological materials are largely unexplored. Future work in this direction should yield enabling technologies that allows the study and direct manipulation of biological processes at the (sub) cellular level.
