This book was released on 2009-12-16 with total page 245 pages. Available in PDF, EPUB and Kindle. Book excerpt: Themulticomponentnatureofbiologicalmembranesandtheirintra- andextracel- lar interactions make direct investigations on the membrane structure and processes nearly impossible. Clearly, a better understanding of the membrane properties and the mechanisms determining membrane protein functions is crucial to the imp- mentation of biosensors, bioreactors and novel platforms for medical therapy. For this reason, the interest in model systems suitable for the construction and study of complex lipid/protein membrane architectures has increased steadily over the years. The classical portfolio of model membranes used for biophysical and - terfacial studies of lipid (bi)layers and lipid/protein composites includes Langmuir monolayers assembled at the water/air interface, (uni- and multi-lamellar) vesicles in bulk (liposomal) dispersion, bimolecular lipid membranes (BLMs), and various types of solid-supported membranes. All these have speci?c advantages but also suffer from serious drawbacksthat limit their technical applications. Polymer m- branes comprised of entirely synthetic or hybrid (synthetic polymer/biopolymer) block copolymersappeared to be an attractive alternative to the lipid-based models. Generally, the synthetic block copolymer membranes are thicker and more stable and the versatility of polymer chemistry allows the adoption of relevant properties for a wide range of applications. This volume provides a vast overview of the physico-chemical and synthetic - pectsofarti?cial membranes. Numerousmembranemodelsaredescribed, including their properties(i. e. swelling, drying, lateral mobility, stability, electrical conduct- ity, etc. ), advantages, and drawbacks. The potential applications of these models are discussed and supported by real examples. Chapter 1 summarizesmethodsfor the stabilizationof arti?cial lipid membranes.

Book excerpt: This is truly an exciting time to be in the ?eld of polymer science. Advances in polymerization methods are providing polymer scientists with the ability to specify and control polymer composition, structure, architecture, and molecular weight to a degree that was not possible just a decade ago. This, in turn, is resulting in many novel application possibilities of polymers ranging from drug delivery systems and nanolithographyto stimuli-responsivematerials and many others. In addition,many of the application areas of polymers – such as coatings, adhesives, thermoplastics, composites, and personal care – are also taking advantage of the ability to design polymersduringtheir developmentefforts. Not to forget,manyof these applications of polymers involve mixing polymers with solvents, catalysts, colorants, and many other ingredients to prepare a formulated product. However, the tuning of polymer composition and structure as well as polymer formulations to optimize the ?nal performance properties can be challenging, - pecially since in many cases several interacting variables need to be optimized simultaneously. This is where the methodologies and techniques of combinatorial and high-throughput experimentation to synthesize and characterize polymer - braries can be an invaluable approach. Simply put, a polymer library is a collection of multiple polymer samples having a systematic variation in one or more variables related to composition, structure, or process. Various methods and strategies have been explored to ef?ciently prepare a large number of polymer samples and also to screen these samples for key properties of interest.

Download or read book Self Assembled Nanomaterials II written by Toshimi Shimizu and published by Springer Science & Business Media. This book was released on 2008-10-28 with total page 200 pages. 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.

Download or read book Organic Electronics written by Gregor Meller and published by Springer Science & Business Media. This book was released on 2009-11-18 with total page 338 pages. Available in PDF, EPUB and Kindle. Book excerpt: Dear Readers, Since the ground-breaking, Nobel-prize crowned work of Heeger, MacDiarmid, and Shirakawa on molecularly doped polymers and polymers with an alternating bonding structure at the end of the 1970s, the academic and industrial research on hydrocarbon-based semiconducting materials and devices has made encouraging progress. The strengths of semiconducting polymers are currently mainly unfolding in cheap and easily assembled thin ?lm transistors, light emitting diodes, and organic solar cells. The use of so-called “plastic chips” ranges from lightweight, portable devices over large-area applications to gadgets demanding a degree of mechanical ?exibility, which would overstress conventionaldevices based on inorganic,perfect crystals. The ?eld of organic electronics has evolved quite dynamically during the last few years; thus consumer electronics based on molecular semiconductors has gained suf?cient market attractiveness to be launched by the major manufacturers in the recent past. Nonetheless, the numerous challenges related to organic device physics and the physics of ordered and disordered molecular solids are still the subjects of a cont- uing lively debate. The future of organic microelectronics will unavoidably lead to new devi- physical insights and hence to novel compounds and device architectures of - hanced complexity. Thus, the early evolution of predictive models and precise, computationally effective simulation tools for computer-aided analysis and design of promising device prototypes will be of crucial importance.

Download or read book New Frontiers in Polymer Synthesis written by Shiro Kobayashi and published by Springer Science & Business Media. This book was released on 2008-09-26 with total page 196 pages. Available in PDF, EPUB and Kindle. Book excerpt: It is generally accepted that a new material is often developed by ?nding a new synthesis method of reaction or a new reaction catalyst. Historically, a typical example may be referred to as a Ziegler–Natta catalyst, which has allowed large-scale production of petroleum-based polyole?ns since the middle of the 20th century. New polymer synthesis, therefore, will hopefully lead to creation of new polymer materials in the 21st century. This special issue contributed by three groups focuses on recent advances in polymer synthesis methods, which handle the cutting-edge aspects of the advanced technology. The ?rst article by Yokozawa and coworkers contains an overview of the - action control in various condensation polymerizations (polycondensations). Advanced technologies enabled the control of stereochemistry (regio-, g- metrical-, and enantio-selections), chemoselectivity, chain topology, and st- chiometry of monomers, giving a high molecular weight polymer. It has been recognized for a long time, however, that polycondensation is a dif?cult p- cess in controlling the reaction pathway, because the reaction is of step-growth and the reactivity of monomers, oligomers, and polymers are almost the same during the reaction and hence, the molecular weight of polymers and its d- tribution (M /M ) are impossible to regulate. The authors’ group developed w n a new reaction system (chain-growth condensation polymerization), changing the nature of polycondensation from step-growth to chain-growth; namely the propagating chain-end is active, allowing for control of the product molecular weight as well as the distribution.

Download or read book Advanced Computer Simulation Approaches for Soft Matter Sciences III written by Christian Holm and published by Springer. This book was released on 2008-12-30 with total page 248 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Soft matter” is nowadays used to describe an increasingly important class of - terials that encompasses polymers, liquid crystals, molecular assemblies building hierarchical structures, organic-inorganic hybrids, and the whole area of colloidal science. Common to all is that ?uctuations, and thus the thermal energy k T and B entropy, play an important role. “Soft” then means that these materials are in a state of matter that is neither a simple liquid nor a hard solid of the type studied in hard condensed matter, hence sometimes many types of soft matter are also named “c- plex ?uids. ” Soft matter, either of synthetic or biological origin, has been a subject of physical and chemical research since the early ?nding of Staudinger that long chain mo- cules exist. From then on, synthetic chemistry as well as physical characterization underwent an enormous development. One of the outcomes is the abundant pr- ence of polymeric materials in our everyday life. Nowadays, methods developed for synthetic polymers are being more and more applied to biological soft matter. The link between modern biophysics and soft matter physics is quite close in many respects. This also means that the focus of research has moved from simple - mopolymers to more complex structures, such as branched objects, heteropolymers (random copolymers, proteins), polyelectrolytes, amphiphiles and so on.
