This book was released on 2013 with total page 59 pages. Available in PDF, EPUB and Kindle. Book excerpt: The self-assembly of individual building blocks with different shapes into close packed ordered structures is prevalent in nature and has drawn much attention of human for long. The close packing of some simple shapes such as sphere and rods has been widely learned and established while the assembly of polyhedral structures is still unsolved and being studied with numerous efforts, of which tetrahedron is one with special interest. However, many previous researches only study the assembly of the building blocks with sizes either too big (tens or hundreds of nanometers) or too small (around one nanometer). Thus, we seek to obtain a size in between by using the newly emerged nano building blocks with precisely defined structures, persistent shapes and outstanding properties, e.g. Polyhedral Oligomeric Silsesquioxane (POSS). We can predict there to be distinctive difference in the self-assembly behavior and structure between the nano-sized molecules and the traditional ones. In this work, two novel claw-like C3v symmetric nano-molecules with different linkages were successfully synthesized by connecting 3 POSS nano-atoms to 1,3,5-Triphenyladmantane. The nano-molecules were carefully designed to ensure they possess enough shape persistent ability and 3-5 nm size, which fills the size gap between traditional small molecules and large colloidal particles. The crystals of the molecules were obtained via solvent evaporation method and the crystal structures would be explored. This work can not only provide us a new way of designing crystals with Nano-sized units but also help us to deepen our understanding of the relationship between molecular structure and crystal structure.

Download or read book Sol Gel Materials written by John D. Wright and published by CRC Press. This book was released on 2018-10-03 with total page 136 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sol-Gel processing methods, first used historically for decorative and constructional materials, were extensively developed in the last century for applications such as glasses, ceramics, catalysts, coatings, composites and fibres. Today they are reaching their full potential, enabling the preparation of new generations of advanced materials not easily accessible by other methods yet using mild, low-energy conditions. The topic is therefore increasingly included in advanced undergraduate, MSc and PhD programmes in the areas of chemistry, physics and materials science. This concise introductory text, written at the advanced undergraduate/first-year postgraduate level, is also suitable as an introduction to the development, mechanisms, chemistry, characterisation methods and applications of the technique. It provides readers with an extensive yet concise grounding in the theory of each area of the subject and details the real and potential applications and the future prospects of sol-gel chemistry.

Book excerpt: ?? Giant molecules are important in our everyday life. But, as pointed out by the authors, they are also associated with a culture. What Bach did with the harpsichord, Kuhn and Flory did with polymers. We owe a lot of thanks to those who now make this music accessible ??Pierre-Gilles de GennesNobel Prize laureate in Physics(Foreword for the 1st Edition, March 1996)This book describes the basic facts, concepts and ideas of polymer physics in simple, yet scientifically accurate, terms. In both scientific and historic contexts, the book shows how the subject of polymers is fascinating, as it is behind most of the wonders of living cell machinery as well as most of the newly developed materials. No mathematics is used in the book beyond modest high school algebra and a bit of freshman calculus, yet very sophisticated concepts are introduced and explained, ranging from scaling and reptations to protein folding and evolution. The new edition includes an extended section on polymer preparation methods, discusses knots formed by molecular filaments, and presents new and updated materials on such contemporary topics as single molecule experiments with DNA or polymer properties of proteins and their roles in biological evolution.

Download or read book Electrochemical Activation of Catalysis written by Costas G. Vayenas and published by Springer Science & Business Media. This book was released on 2007-05-08 with total page 597 pages. Available in PDF, EPUB and Kindle. Book excerpt: I knew nothing of the work of C. G. Vayenas on NEMCA until the early nineties. Then I learned from a paper of his idea (gas interface reactions could be catalyzed electrochemically), which seemed quite marvelous; but I did not understand how it worked. Consequently, I decided to correspond with Professor Vayenas in Patras, Greece, to reach a better understanding of this concept. I think that my early papers (1946, 1947, and 1957), on the relationship between the work function of metal surfaces and electron transfer reactions thereat to particles in solution, held me in good stead to be receptive to what Vayenas told me. As the electrode potential changes, so of course, does the work function at the interface, and gas metal reactions there involve adsorbed particles which have bonding to the surface. Whether electron transfer is complete in such a case, or whether the effect is on the desorption of radicals, the work function determines the strength of their bonding, and if one varies the work function by varying the electrode potential, one can vary the reaction rate at the interface. I got the idea. After that, it has been smooth sailing. Dr. Vayenas wrote a seminal article in Modern Aspects of Electrochemistry, Number 29, and brought the field into the public eye. It has since grown and its usefulness in chemical catalytic reactions has been demonstrated and verified worldwide.
