Book Synopsis Giant Shape Amphiphiles Based on Polyoxometalates (POMs)-polyhedra Oligomeric Silsesquioxane (POSS) Hybrids by : Jing Jiang
Download or read book Giant Shape Amphiphiles Based on Polyoxometalates (POMs)-polyhedra Oligomeric Silsesquioxane (POSS) Hybrids written by Jing Jiang and published by . This book was released on 2013 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The concept of shape amphiphiles was proposed about 10 years ago, describing particles that formed by building blocks with distinct shapes and interactions through chemical bonds. Among various classes of nano building blocks, Polyoxometalates (POMs) and Polyhedra Oligomeric Silsesquioxanes (POSS) are two classes that are ubiquitous in hybrid material research fields with potential applications ranging from biomaterials, catalyst engineering to photovoltaic applications. The shape amphiphiles formed by POMs and POSS through covalent bonds, thus, would be a class of promising hybrid material that possesses outstanding properties from both components. Herein, a prototype of "giant shape amphiphile" with one hydrophobic isobutyl POSS (BPOSS) and one hydrophilic POM (Lindqvist-type hexamolybdate) is studied. We report the molecular design, synthesis strategy, characterization, and thermal analysis studies. Sonogashira coupling is utilized to synthesize the BPOSS-POM hybrids. The hybrids were fully characterized by nuclear magnetic resonance (NMR) spectroscopy, Fourier transform infrared spectroscopy (FT-IR), and matrix-assisted laser desorption ionization time-of-flight (MALDI-TOF) mass spectroscopy. Differential scanning calorimetry (DSC) is used to study the phase transition behavior of this material. And the structure information of single crystal formed by BPOSS-POM will be the focus of the future work.
Book Synopsis Rational Controlled Self-assembly Behavior of Inorganic-organic Hybrids in Solution by : Yang Chu
Download or read book Rational Controlled Self-assembly Behavior of Inorganic-organic Hybrids in Solution written by Yang Chu and published by . This book was released on 2017 with total page 151 pages. Available in PDF, EPUB and Kindle. Book excerpt: In the past several decades, self-assembly of amphiphiles in solutions has attracted great interest of researchers due to their unique properties and applications. Besides the well-explored small-molecule surfactants and block-copolymers, giant surfactants also known as inorganic-organic amphiphilic hybrids have been regarded as a new attractive topic because they contain functional (e.g., catalytic, magnetic, oxidation-reduction redox or biologically active) inorganic nanoparticles/molecular clusters which simultaneously act as surfactant polar head groups. The self-assembly/disassembly can be triggered by different kinds of external stimuli like light, heat, magnetic field or solution polarity. Besides, the morphology and size of the assemblies are also tunable by the experimental conditions and molecular structures. In this dissertation, three representative kinds of hybrids, which include multi-headed giant surfactants based on polystyrene (PS)-polyhedral oligomeric silsesquioxane (POSS) conjugates with different number and topology of POSS heads, triangular shaped PS-POSS hybrids with different length of PS linkers and spiropyran (SP)-polyoxometalate (POM)-alkyl hybrids, are prepared to study the effect of hydrophilic head groups, hydrophobic linkers and change of hydrophobicity on the self-assembly behavior. Dynamic light scattering (DLS) and static light scattering (SLS) are used during the whole process of self-assembly to suggest the size and morphology of the assemblies and electron microscopy and atomic force microscopy confirm the results obtained by light scattering techniques. We found the rational control of the self-assembly behavior of inorganic-organic hybrids in solution can be successfully achieved due to their multiple-responsive property on light, solvent polarity, molecular structures and solution concentration.

Book Synopsis Polymer/POSS Nanocomposites and Hybrid Materials by : Susheel Kalia
Download or read book Polymer/POSS Nanocomposites and Hybrid Materials written by Susheel Kalia and published by Springer. This book was released on 2018-11-27 with total page 462 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an overview of polymer nanocomposites and hybrid materials with polyhedral oligomeric silsesquioxanes (POSS). Among inorganic nanoparticles, functionalized POSS are unique nano-building blocks that can be used to create a wide variety of hybrid and composite materials, where precise control of nanostructures and properties is required. This book describes the influence of incorporation of POSS moieties into (organic) polymer matrices on the mechanical, thermal and flammability behavior of composites and hybrid organic-inorganic materials. Importantly, POSS-containing materials can be bio-functionalized by linking e.g. peptides and growth factors through appropriate surface modification in order to enhance the haemo-compatibility of cardiovascular devices made of these materials. This volume includes descriptions of synthesis routes of POSS and POSS-containing polymeric materials (e.g. based on polyolefines, epoxy resins and polyurethanes), presentation of POSS’ role as flame retardants and as biocompatible linker, as well as the depiction of decomposition and ageing processes.

Available in PDF, EPUB and Kindle. Book excerpt: With the recent advent of nanotechnology, research and development in the area of nanostructured materials has gained unprecedented prominence. Novel materials with potentially exciting new applications are being discovered at a much higher rate than ever before. Innovative tools to fabricate, manipulate, characterize and evaluate such materials are being developed and expanded. To keep pace with this extremely rapid growth, it is necessary to take a breath from time to time, to critically assess the current knowledge and provide thoughts for future developments. This book represents one of these moments, as a number of prominent scientists in nanostructured materials join forces to provide insightful reviews of their areas of expertise, thus offering an overall picture of the state-- the art of the field. Nanostructured materials designate an increasing number of materials with designed shapes, surfaces, structures, pore systems, etc. Nanostructured materials with modified surfaces include those whose surfaces have been altered via such techniques as grafting and tethering of organic or organometallic species, or through various deposition procedures including electro, electroless and vapor deposition, or simple adsorption. These materials find important applications in catalysis, separation and environmental remediation. Materials with patterned surfaces, which are essential for the optoelectronics industry, constitute another important class of surface-modified nanostructured materials. Other materials are considered nanostructured because of their composition and internal organization.

Book Synopsis Supramolecular Amphiphiles by : Xi Zhang
Download or read book Supramolecular Amphiphiles written by Xi Zhang and published by Royal Society of Chemistry. This book was released on 2017-06-15 with total page 183 pages. Available in PDF, EPUB and Kindle. Book excerpt: An amphiphile is a molecule that contains a hydrophilic part and a hydrophobic part, linked by covalent bonding. Supramolecular amphiphiles (supra-amphiphiles) are amphiphiles linked by non-covalent interactions. As they employ non-covalent interactions, these species demonstrate adaptability and reversibility in conformational transformation, making them one of the most important emerging species in supramolecular chemistry. They have proven important in bridging the gap between molecular architecture and functional assembly. This book is written and edited by the current leaders in the topic and contains a foreword from Professor Jean-Marie Lehn, a father of the supramolecular chemistry field. Bringing together supramolecular chemistry and colloidal and interfacial science, the book provides a detailed and systematic introduction to supramolecular amphiphiles. Chapters explain how to employ non-covalent interactions to fabricate supra-amphiphiles. The book opens with an introduction to the history and development of the field, followed by chapters focussing on each type of interaction, including host-guest interaction, electrostatic interaction, charge-transfer interaction, hydrogen bonding and dynamic covalent bonds. This book will be a valuable resource for students new to this field and experienced researchers wanting to explore the wider context of their work.

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.
