Book Synopsis Macromolecular Structure Evolution of Giant Molecules Via "click" Chemistry by : Hao Su

Available in PDF, EPUB and Kindle. Book excerpt: Physical properties of giant molecules are intimately dependent upon their primary chemical structures and molecular topologies and thus, precise controls of these structures and topologies are an important pursuit in developing new functional materials. In this paper, we report the rational molecular design and cascading "click" synthesis of three types of polyhedral oligomeric silsesquioxane (POSS)-based asymmetric giant gemini surfactants (AGGSs) including (1) consisting of two polymer tails differing in chain lengths and two identical heads, (2) having two distinct functional heads and two similar tails, and (3) possessing two tails of different lengths and two distinct head groups. The syntheses were achieved in a convenient, efficient, and modular way, allowing the precise control and rigorous tuning of both of polymer tail composition and POSS surface chemistry in these AGGSs. The synthetic processes can be rapidly accomplished within about 5 hours and only require non-chromatographic purification. Our study expands the scope of synthetically available giant surfactants along with the route of macromolecular structure evolution of giant molecules inspired by further decreasing the symmetry of POSS-based giant molecules using "click" chemistry.

Book Synopsis Macromolecules by : Hans-Georg Elias
Download or read book Macromolecules written by Hans-Georg Elias and published by Springer Science & Business Media. This book was released on 2013-06-29 with total page 1228 pages. Available in PDF, EPUB and Kindle. Book excerpt: Like so many of its kind, this textbook originated from the requirements of teaching. While lecturing on macromolecular science as a required subject for chemists and materials scientists on the undergraduate, graduate, and postgraduate levels at Swiss Federal Institute of Technology at Zurich (1960-1971), I needed a one-volume textbook which treated the whole field of macromolecular science, from its chemistry and physics to its applications, in a not too elementary manner. This textbook thus intends to bridge the gap between the often oversimplified introductory books and the highly specialized texts and monographs that cover only parts of macromolecular science. This first English edition is based on the third German edition (1975), which is about 40% different from the first German edition (1971), a result of rapid progress in macromolecular science and the less rapid education of the writer. This text intends to survey the whole field of macromolecular science. Its organization results from the following considerations. The chemical structure of macromolecular compounds should be independent of the method of synthesis, at least in the ideal case. Part I is thus concerned with the chemical and physical structure of macro molecules. Properties depend on structure. Solution properties are thus discussed in Part II, solid state properties in Part III. There are other reasons for discussing properties before syntheses: For example, it is difficult to under stand equilibrium polymerization without knowledge of solution thermody of the glass temperature, etc.
Book Synopsis Design, Synthesis and Self-assembly of Giant Molecules with Precisely Controlled Heterogeneities, Including Composition, Functionality, Topology and Sequence by : Wei Zhang
Download or read book Design, Synthesis and Self-assembly of Giant Molecules with Precisely Controlled Heterogeneities, Including Composition, Functionality, Topology and Sequence written by Wei Zhang and published by . This book was released on 2016 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: In biological systems, it is well-known that the activity and function of biomacromolecules are dictated not only by their primary chemical structures, but also by their secondary, tertiary and quaternary hierarchical structures. Achieving similar levels of control in synthetic macromolecules has yet to be demonstrated. In 1960, Feynman raised a fundamental question: "What would the properties of materials be if we could really arrange the atoms the way we want them?" It is difficult to answer this question at truly atomic level. However, by taking the advantage of the unique giant molecular system recently developed by our group, we are trying to answer it at the "nanoatom" length scale in this dissertation. We started with design, syntheses and crystal structure analyses of three series dyads of sphere-plate giant shape amphiphiles with distinct shapes and precise chemical linkages based on C60-triphenylene (sphere-triangle), C60-perylene diimide (sphere-rectangle) and C60-Porphyrin (sphere-square). We then developed a novel synthetic methodology using orthogonal "click" chemistries, strain-promoted azide-alkyne cycloaddition (SPAAC), oxime ligation and thiol-ene click coupling (TECC), for preparing a library of polystyrene (PS)-polyhedral oligomeric silsesquioxane (POSS) giant surfactants with precisely arranged nano-building blocks. The heterogeneity of primary chemical structure can be precisely controlled and is reflected in the self-assembled supramolecular structures in bulk or in solution. The composition (the volume fraction of hydrophilic "nanoatoms") and functionality are the crucial to determine the assembled structures, illustrated by a series of linear configured PSm-(XPOSS)n. The functionality and topology are also found to affect the assembled structures when the volume fractions are identical, demonstrated by several linear and branched PSm-(XPOSS)n giant surfactants. Furthermore, the sequence effect is explored by comparing the self-assembly behaviors of a pair of sequence isomers. In order to step further answering Feynman's inquire, we extend the synthetic method to prepare truly precise "nanoatom" chains or dendrimers with polydispersity Đ equal to 1, which also form varies order supramolecular structures as we tune their primary chemical structures. Our work offers a promising opportunities to manipulate the hierarchical heterogeneities of giant molecules via precise and modular assemblies of various nano-building blocks, and provides a platform for making precise nanostructures that are not only scientific intriguing but also technologically relevant.
Book Synopsis Mega Molecules by : Hans-Georg Elias
Download or read book Mega Molecules written by Hans-Georg Elias and published by Springer. This book was released on 1987-05-25 with total page 202 pages. Available in PDF, EPUB and Kindle. Book excerpt: All life is based on big molecules, scientifically called "mac romolecules". Humans, animals, and plants cease to exist without these structural, reserve, and transport molecules. No life can be propagated without macromolecular DNA and RNA. Without macromolecules, we would only dine on water, sugars, fats, vitamins and salts but had to relinquish meat, eggs, cereals, vegetables, and fruits. We would not live in houses since wood and many stones consist of macromole cules. Without macromolecules, no clothes since all fibers are made from macromolecules. No present-day car could run: All tires are based on macromolecules. Without macromole cules no photographic films, no electronics ... If macromolecules are so important then why is commonly so little known about their roles and why are they so little mentioned in school, if at all? As often in human history, tra dition is important and science makes no exception. Chemis try was established as the chemistry of low molecular weight compounds since these were most easy to investigate, charac terize, and convert. A beautiful tower of thought was erected by the chemical sciences long before the idea of giant mole cules, macromolecules, took hold. There was no space for newcomers in this tower. Even today one can learn about chemistry without hearing a word about macromolecules.

Available in PDF, EPUB and Kindle. Book excerpt: An introduction to the state-of-the-art of the diverse self-assembly systems Self-Assembly: From Surfactants to Nanoparticles provides an effective entry for new researchers into this exciting field while also giving the state of the art assessment of the diverse self-assembling systems for those already engaged in this research. Over the last twenty years, self-assembly has emerged as a distinct science/technology field, going well beyond the classical surfactant and block copolymer molecules, and encompassing much larger and complex molecular, biomolecular and nanoparticle systems. Within its ten chapters, each contributed by pioneers of the respective research topics, the book: Discusses the fundamental physical chemical principles that govern the formation and properties of self-assembled systems Describes important experimental techniques to characterize the properties of self-assembled systems, particularly the nature of molecular organization and structure at the nano, meso or micro scales. Provides the first exhaustive accounting of self-assembly derived from various kinds of biomolecules including peptides, DNA and proteins. Outlines methods of synthesis and functionalization of self-assembled nanoparticles and the further self-assembly of the nanoparticles into one, two or three dimensional materials. Explores numerous potential applications of self-assembled structures including nanomedicine applications of drug delivery, imaging, molecular diagnostics and theranostics, and design of materials to specification such as smart responsive materials and self-healing materials. Highlights the unifying as well as contrasting features of self-assembly, as we move from surfactant molecules to nanoparticles. Written for students and academic and industrial scientists and engineers, by pioneers of the research field, Self-Assembly: From Surfactants to Nanoparticles is a comprehensive resource on diverse self-assembly systems, that is simultaneously introductory as well as the state of the art.
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.

Book Synopsis Concepts of Biology by : Samantha Fowler
Download or read book Concepts of Biology written by Samantha Fowler and published by . This book was released on 2018-01-07 with total page 618 pages. Available in PDF, EPUB and Kindle. Book excerpt: Concepts of Biology is designed for the single-semester introduction to biology course for non-science majors, which for many students is their only college-level science course. As such, this course represents an important opportunity for students to develop the necessary knowledge, tools, and skills to make informed decisions as they continue with their lives. Rather than being mired down with facts and vocabulary, the typical non-science major student needs information presented in a way that is easy to read and understand. Even more importantly, the content should be meaningful. Students do much better when they understand why biology is relevant to their everyday lives. For these reasons, Concepts of Biology is grounded on an evolutionary basis and includes exciting features that highlight careers in the biological sciences and everyday applications of the concepts at hand.We also strive to show the interconnectedness of topics within this extremely broad discipline. In order to meet the needs of today's instructors and students, we maintain the overall organization and coverage found in most syllabi for this course. A strength of Concepts of Biology is that instructors can customize the book, adapting it to the approach that works best in their classroom. Concepts of Biology also includes an innovative art program that incorporates critical thinking and clicker questions to help students understand--and apply--key concepts.

Book Synopsis Macromolecular Chemistry by : A D Jenkins
Download or read book Macromolecular Chemistry written by A D Jenkins and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 474 pages. Available in PDF, EPUB and Kindle. Book excerpt: Specialist Periodical Reports provide systematic and detailed review coverage of progress in the major areas of chemical research. Written by experts in their specialist fields the series creates a unique service for the active research chemist, supplying regular critical in-depth accounts of progress in particular areas of chemistry. For over 80 years the Royal Society of Chemistry and its predecessor, the Chemical Society, have been publishing reports charting developments in chemistry, which originally took the form of Annual Reports. However, by 1967 the whole spectrum of chemistry could no longer be contained within one volume and the series Specialist Periodical Reports was born. The Annual Reports themselves still existed but were divided into two, and subsequently three, volumes covering Inorganic, Organic and Physical Chemistry. For more general coverage of the highlights in chemistry they remain a 'must'. Since that time the SPR series has altered according to the fluctuating degree of activity in various fields of chemistry. Some titles have remained unchanged, while others have altered their emphasis along with their titles; some have been combined under a new name whereas others have had to be discontinued. The current list of Specialist Periodical Reports can be seen on the inside flap of this volume.
