Available in PDF, EPUB and Kindle. Book excerpt: "The story is told by THE inventor-pioneer-master in the field and is accompanied by amazing illustrations... [it] will become an absolute reference and a best seller in chemistry!" —Alberto Credi "... the great opus on the mechanical bond. A most impressive undertaking!" — Jean-Marie Lehn Congratulations to co-author J. Fraser Stoddart, a 2016 Nobel Laureate in Chemistry. In molecules, the mechanical bond is not shared between atoms—it is a bond that arises when molecular entities become entangled in space. Just as supermolecules are held together by supramolecular interactions, mechanomolecules, such as catenanes and rotaxanes, are maintained by mechanical bonds. This emergent bond endows mechanomolecules with a whole suite of novel properties relating to both form and function. They hold unlimited promise for countless applications, ranging from their presence in molecular devices and electronics to their involvement in remarkably advanced functional materials. The Nature of the Mechanical Bond is a comprehensive review of much of the contemporary literature on the mechanical bond, accessible to newcomers and veterans alike. Topics covered include: Supramolecular, covalent, and statistical approaches to the formation of entanglements that underpin mechanical bonds in molecules and macromolecules Kinetically and thermodynamically controlled strategies for synthesizing mechanomolecules Chemical topology, molecular architectures, polymers, crystals, and materials with mechanical bonds The stereochemistry of the mechanical bond (mechanostereochemistry), including the novel types of dynamic and static isomerism and chirality that emerge in mechanomolecules Artificial molecular switches and machines based on the large-amplitude translational and rotational motions expressed by suitably designed catenanes and rotaxanes. This contemporary and highly interdisciplinary field is summarized in a visually appealing, image-driven format, with more than 800 illustrations covering both fundamental and applied research. The Nature of the Mechanical Bond is a must-read for everyone, from students to experienced researchers, with an interest in chemistry’s latest and most non-canonical bond.

This book was released on 2012 with total page 404 pages. Available in PDF, EPUB and Kindle. Book excerpt: Surface-enhanced Raman scattering (SERS) is a powerful analytical tool and the recent expansion of substrates for SERS measurement broadens its field of applications, including SERS-based immuno-nanosensing. This dissertation describes the optimization and characterization of self-assembled monolayer (SAM) multilayer SERS substrates for improving performance of different types of substrates. SERS substrates derived from metal film on nanostructures were modified with multiple metal films interspaced with SAM dielectric spacers to achieve multilayered SERS substrates. The fundamental concept of this substrate geometry exploited the cumulative effect of the multiple electromagnetic fields and various properties of SAMs to optimize SERS enhancement of multilayer SERS substrates to about 20-fold compared to conventional substrates.

Download or read book Engineering Noble metal Nanoparticles for Sensing and Imaging with Surface enhanced Raman Scattering written by Matthew Rycenga and published by . This book was released on 2011 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: This research investigated the surface-enhanced Raman scattering (SERS) from Ag and Au nanoparticles with an aim to better understand the SERS mechanism and to implement this technique for single-molecule detection and imaging. In addition, SERS was used as a sensitive probe to study molecules confined to a nanoparticle's surface. The first part of this work focused on measuring the SERS from different Ag and Au nanoparticles and determining how their structural and physical properties affect SERS. The effects of shape, size, and Au-Ag composition on SERS are determined using Ag nanocubes, Ag nanospheres, and Au-based nanocages. I also demonstrate several techniques used to study the SERS of single nanoparticles, one at a time, which has provided significant insight into the SERS effect. I then discuss the development of a new and simple way to create large SERS enhancements by taking advantage of the supporting substrate of a nanoparticle. In this technique, simply depositing a single Ag nanocube on a metal substrate can increase its SERS enhancements to levels capable of single-molecule detection. In the second part of this work I used SERS as a molecular probe to understand how glucose molecules interact at a nanocube's surface, and as an optical thermometer to quantify the temperature change at the surface of a Au-based nanocage during the photothermal effect. The nanoparticles were coated with highly ordered self-assembled monolayers (SAMs), and then SERS was used to determine the structural and conformational changes in the SAMs as a result of perturbations from the environment. This allowed me to use SERS to directly probe the molecules on the nanoparticle's surface. In the final part of this work, I used nanocubes and nanospheres in SERS imaging. The resolution, sensitivity, and penetration depth are determined for our Raman microprobe system. In addition, phantoms are used to generate SERS images of three-dimensional microstructures.

Download or read book Electrochemistry of Immobilized Particles and Droplets written by Fritz Scholz and published by Springer Science & Business Media. This book was released on 2005-12-06 with total page 299 pages. Available in PDF, EPUB and Kindle. Book excerpt: Immobilizing particles or droplets on electrodes is a novel and most powerful technique for studying the electrochemical reactions of three-phase systems. It gives access to a wealth of information, ranging from quantitative and phase analysis to thermodynamic and kinetic data of electrode processes. Three-phase electrodes with immobilized droplets provide information on the electrochemistry of redox liquids and of compounds dissolved in inert organic liquids. Such measurements allow the determination of the Gibbs energies of the transfer of cations and anions between immiscible solvents, and thus make it possible to assess the hydrophobicity of ions – a property that is of great importance for pharmaceutical applications, biological studies, and for many fields of chemistry. The monograph gives, for the first time, a comprehensive overview of the results published in more than 300 papers over the last 15 years. The experiments are explained in detail, applications from many different fields are presented, and the theoretical basis of the systems is outlined.
