Book excerpt: Nanostructures with critical dimensions less than 100nm endow materials with unique and often superior mechanical, electronic, magnetic and optical properties, which are expected to lead to numerous advanced applications. The current nanotechnology roadmap focuses on exploration and prediction of novel properties of materials at the nanoscale, of efficient synthesis and manufacture of nanoscale materials, and of the integration of nanoscale materials into real-world devices and applications. Self assembly, in which complex building blocks are organized into hierarchical structures via noncovalent interactions, has emerged as one of the most promising techniques for the efficient fabrication of nanostructured materials. This proceedings volume focuses on synthesis of novel nanostructured materials via self assembly, the fundamental understanding of self-assembly processes, the unique properties of nanostructured materials, and their potential applications. The volume is a compendium of current discussions of these topics with special emphasis on the synthesis and fabrication of nanostructured materials via self assembly of organic molecules such as surfactants and block copolymers, inorganic and metallic nanoclusters, nanoparticles, nanorods, nanowires, and other building blocks. It also contains reports on the novel properties and applications of nanostructured materials.

Available in PDF, EPUB and Kindle. Book excerpt: Nanotechnology is the creation of useful materials, devices, and systems through the control of matter on the nanometer-length scale. This takes place at the scale of atoms, molecules, and supramolecular structures. In the world of chemistry, the rational design of molecular structures and optimized control of self-assembly conditions have enabled us to control the resultant self-assembled morphologies having 1 to 100-nm dimensions with sing- nanometer precision. This current research trend applying the bottom-up approach to molecules remarkably contrasts with the top-down approach in nanotechnology, in which electronic devices are miniaturizing to smaller than 30 nm. However, even engineers working with state-of-the-art computer te- nology state that maintaining the rate of improvement based on Moore’s law will be the most dif?cult challenge in the next decade. On the other hand, the excellent properties and intelligent functions of a variety of natural materials have inspired polymer and organic chemists to tailor their synthetic organic alternatives by extracting the essential structural elements. In particular, one-dimensional structures in nature with sophis- cated hierarchy, such as myelinated axons in neurons, tendon, protein tubes of tubulin, and spider webs, provide intriguing examples of integrated functions and properties. Against this background, supramolecular self-assembly of one-dimensional architectures like ?bers and tubes from amphiphilic molecules, bio-related molecules, and properly designed self-assembling polymer molecules has - tracted rapidly growing interest.

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.

This book was released on 2008 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In recent years, it was suggested that the performance of nanostructure-based optoelectronic devices, in particular quantum dot-based devices, may be enhanced when the active region of the device consists of dots that are coupled laterally and/or vertically. The electronic coupling between the dots provides a new degree of freedom in engineering the electronic bandstructure of the nanostructures. For example, strong electronic coupling between two dots defines a new entity, known as a quantum dot molecule (QDM). We provide in this thesis a comparative theoretical and experimental study of structures consisting of two layers of vertically coupled InAs/GaAs QDs, grown by molecular beam epitaxy on (001) GaAs substrates, in which the GaAs barrier layer thickness was varied between 4 and 10 nm, thus insuring very strong coupling between the dot layers and the existence of "molecule-like" behavior. Theoretically, to understand the nature of the electronic and optical properties of the self-assembled dots and molecules, we determined the strain distribution in the dots. The strain effects were included via the deformation potential theory in an eight-band k p model to calculate the respective electronic band structures. Our experimental investigations of the optical and structural properties of QDM structures confirm the formation of QDMs with energy splittings that agree well with the results of our calculations.

This book was released on 1998-01-15 with total page 570 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the latest of the “Kirchberg-Proceedings”. The previous 11 International Winterschools on Electronic Properties of Novel Materials, all held in Kirchberg, Austria, were devoted to conducting polymers, high temperature superconductors, fullerenes, and carbon nanotubes. Fullerenes and nanotubes are still in the center of interest, but the topic of the school and the proceedings is molecular nanostructures in general. The organizers have attempted to treat carbon nanostructures as a special case of molecular nanostructures, which also include silicon clusters, gold clusters, vanadium oxide tubes, and many others. The Winterschool provides a platform for reviewing and discussing new developments in the field of molecular nanostructures and their applications. Materials discussed include fullerenes, fullerene-derived structures, carbonaceous nanotubes, non-carbonaceous nanotubes, layer by layer systems, molecular clusters, new phases of carbon, endohedral compounds and related materials. The book aims to give an overview of the current status of fullerenes, carbon-nanotubes and related molecular nanostructures. The majority of the contributions present the latest results of experiments and calculations conducted in the field. However, about a dozen contain some degree of instructional material which even newcomers will benefit from.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Adsorbate-induced modification of semiconductor or metal surfaces creates a nano-scale quantum structure which offers a rich vein of exotic physical phenomena for investigation. Human desire to harness these properties for technological or scientific purposes has led to extensive experimental and theoretical investigations. This dissertation focuses on the ab initio simulations of atomic, electronic, optical, and transport properties of nano-scale systems. The calculated results for indium nanowires on the Si(111) surface identify their atomic structure and reveal a phase transition at low temperature. Transport simulations on the self-assembled monolayer of ferrocenyl-alkanethiolate on Au(111) surface show negative difference resistance, which is in very good agreement with experimental observations. This opens a new opportunity for applications in nanoscale molecular devices.

This book was released on 2018 with total page 141 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bio-nanotechnology has become a widespread exciting field of research as the basic biological structure of bio-inspired materials and nanotechnology share the common length scale. Bio-nanotechnology, which is mainly based on bio-inspired nanostructured materials, has potential applications in nanomedicine, drug delivery, bio-sensors, and bio-degradable electronic devices. The nanostructures obtained from biomolecules are attractive due to their biocompatibility for molecular recognition, ease of chemical modification, and the ability to scaffold other organic and inorganic materials. Peptide nanostructures formed through the self-assembly process of the basic building block of diphenylalanine show promising applications in biodegradable electronic devices, drug delivery, catalysis agent, waveguide, and frequency converter. This research focusses on the self-assembly process in a dipeptide, L, L diphenylalanine (FF) and exploring its electronic, optical, and magnetic properties. The role of solvents in the self-assembly process of FF is explored by combining density functional theory (DFT) along with experimental characterization techniques such as electron microscopy, Raman scattering, and x-ray diffraction (XRD). One of the objectives of this work was to explore the nonlinear optical (NLO) properties of FF nanostructures via second harmonic generation (SHG). The ratio of the nonlinear optical coefficients was obtained from individual FF nanotubes as a function of the tube diameter and thermal annealing conditions. The ratio of the shear to the longitudinal component (d[subsrcipt 15]/d[subsrcipt33]) of the NLO coefficient increases with the diameter of the tubes. One of the transverse components, d[subsrcipt]31, of the NLO coefficient is found to be negative, and its magnitude with respect to the longitudinal component (d[subsrcipt33]) increases with the tube diameter. Thermal treatment of individual FF tubes has a similar effect as increasing the diameter of the tubes in SHG polarimetry. The functionalization of FF micro-nanostructures (FF-MNS) with nanomaterials was studied. FF-MNS with Ag or Au nanoparticles were explored in surface-enhanced Raman scattering (SERS). Such self-assembled nanostructures provide a natural template for tethering Au and Ag nanoparticles (Nps) due to its fractal surface. The FF-MNS undergo an irreversible phase transition from hexagonal packing (hex) to an orthorhombic (ort) structure at [tilde]150 [degree sign]C. The metal Nps form chains on hex FF-MNS as inferred from transmission electron microscopy images and a uniform non-aggregated distribution in the ort phase. The SERS spectra obtained from R6G bound to FF-MNSs with AuNps show a higher enhancement for the ort phase compared with the hex phase. The experimental results agree well with our calculated Raman spectra of model systems using DFT. Our results indicate that FF-MNS both in the hex and ort phase can be used as substrates for SERS analysis with different metal Nps, opening up a novel class of optically active bio-based substrates. The use of magnetic nanoparticles with biomolecules offers a versatile path for tuning the functionality of the composite material for several applications. The functionalization of FF-MNS with cobalt ferrite (CFO) magnetic nanoparticles was achieved. The interaction between CFO nanoparticles and FF-MNS was investigated by optical spectroscopy, x-ray photoelectron spectroscopy (XPS), and magnetization measurements. The changes in the XPS data from pristine FF-MNS and CFO:FF-MNS are indicative of a charge transfer process from CFO to FF-MNS, changing the electronic states of the Fe[superscript 2+] and Co[superscript 2+] ions. A comparison of the magnetic characterization from CFO nanoparticles and CFO:FF-MNS shows a higher saturation magnetization from the nanocomposite sample, which is attributed to a change in the cationic distribution in CFO upon binding with the peptide. We were further successful in demonstrating the application of FF-MNS as a bio-degradable active layer in an organic light emitting diode (OLED). FF-MNS were functionalized with two blue-emitting conducting polymers: di-octyl-substituted polyfluorene (PF8) and ethyl-hexyl polyfluorene (PF2/6), and used as an active layer in an OLED architecture. A combination of molecular dynamics and experimental characterization techniques reveals a stronger binding mechanism for PF8 compared to PF2/6 with FF-MNS. Biodegradability tests from FF-MNS:PF8 nanocomposite films show more than 80% weight loss in 2 h by enzymatic action compared to PF8 pristine films, which do not degrade. Self-assembled FF-MNS with organic semiconductors open up a new generation of biocompatible and biodegradable materials in organic electronics.
