This book was released on 2012-12-06 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains the major portion of the material given at the NATO Advanced Study Institute, held at the University of Strathclyde, Glasgow, UK. , September 6th-18th, 1981. The original idea germin ated in a conversation between the organisers on a cold December night in 1978 in the depths of the Oxfordshire countryside. At that time we felt that the chemical physics of macromolecules in the solid state was running on two parallel tracks, namely structure and dynamics. The contact between the two appeared to be slight. We were also concerned that the degree of srecial knowledge now required for any one technique essentially prevented people from learning the important features of other investigation methods. Consequently, we have attempted to bring together leading authorities on both structural and dynamic properties of solid polymers in the hope that the combination of both types of discussion will be synergistic. The choice of main subjects is our own and we are aware that some areas have been omitted. HOvlever, to be comprehensive would have made an already large volume enormous. Y'Je therefore chose to concentrate on what were, in our opinion, the major areas. Nonetheless, it is apparent that much ori~inal material appears here, especially in those contri butions which are more theoretical in concent, the full experimental iMnlications of which have yet to be investigated.

Download or read book Characterization of the Behaviour of Solution responsive Polymers by Fluorescence written by Michael Andrew Theodore Fowler and published by . This book was released on 2014 with total page 298 pages. Available in PDF, EPUB and Kindle. Book excerpt: Two families of amphiphilic polymers were characterized with respect to their ability to respond to changing solution conditions using steady-state and time-resolved fluorescence. Firstly, a series of 5 sequential amphiphilic polypeptides consisting of hydrophilic and ionizable aspartic acid (Asp) and hydrophobic phenylalanine (Phe) in varying sequence (AspxPhey)n were studied. The effect of pH on the collapse and aggregation behaviour of the samples was investigated using light scattering which determined that the samples became insoluble when the fraction of ionized amino acids decreased below 0.2. Pyrene fluorescence measurments demonstrated that hydrophobic aggregate formation was the cause of this behaviour. The fluorescence and light scattering experiments yielded a detailed description of how pH affects the collapse and aggregation behaviour of amphiphilic polypeptides. Secondly, a series of poly(N-isopropylacrylamide) chains in aqueous solution, varying in length and end-labelled with pyrene (Py2-PNIPAM), were studied with respect to their temperature dependent solubility using turbidimetry, light scattering, and fluorescence. The cloud point temperature (Tc) of the Py2-PNIPAM samples was found to increase with increasing chain length. Steady-state fluorescence spectra yielded the ratio of excimer intensity to that of monomer intensity, or (IE/IM)SS, which reached a maximum at Tc. Time-resolved fluorescence decays were analyzed using Model-Free Analysis (MFA). The MFA yielded the average rate constant of excimer formation k, and the parameters fagg, fdiff and ffree, which reflect the molar fractions of pyrenes that form excimer from pre-formed aggregates, form excimer by diffusion, and do not form excimer, respectively. Increasing the temperature above Tc caused a strong decrease in k and ffree, and a sharp rise in fdiff, which is consistent with the formation of mesoglobules. Increasing the temperature above the dehydration temperature of unlabelled PNIPAM (Tm = 34 oC) caused the distribution of pyrene to stabilize. The third study focused on aqueous mixtures of Py2-PNIPAM and unlabelled PNIPAM, and their ability to mix when the temperature was raised above Tm. Using turbidimetry, separate transitions for Py2-PNIPAM and unlabelled PNIPAM were identified. Steady-state fluorescence of the labelled chains demonstrated separate (IE/IM)SS transitions for the labelled and unlabelled chains as well. The MFA of the time-resolved fluorescence decays yielded no transition in k at Tm, while fagg, fdiff and ffree showed transitions consistent with unlabelled PNIPAM entering the Py2-PNIPAM mesoglobules. This led to the conclusion that the two polymers are able to mix at and above Tm, and that the mesoglobules are not frozen and vitreous. Fourthly, a variety of pyrene-labelled polymers in organic solution were studied using steady-state and time-resolved fluorescence, where the results of Birks' Scheme and the Fluorescence Blob Model (FBM) were compared to the results of the MFA. The MFA was found to be able to faithfully reproduce the results of the other, more established, models. In addition, the MFA allowed the calculation of (IE/IM)SPC, the ratio of excimer to monomer intensity as determined by time-resolved fluorescence, which scaled linearly with both (IE/IM)SS and k. From this it was concluded that the MFA is able to fit the decays of pyrene-labelled polymers with any architecture studied thus far, but also provides an absolute measure of IE/IM which can be reproduced in any lab.

Download or read book Polymer Solutions written by Iwao Teraoka and published by John Wiley & Sons. This book was released on 2004-04-07 with total page 355 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polymer Solutions: An Introduction to Physical Properties offers a fresh, inclusive approach to teaching the fundamentals of physical polymer science. Students, instructors, and professionals in polymer chemistry, analytical chemistry, organic chemistry, engineering, materials, and textiles will find Iwao Teraoka’s text at once accessible and highly detailed in its treatment of the properties of polymers in the solution phase. Teraoka’s purpose in writing Polymer Solutions is twofold: to familiarize the advanced undergraduate and beginning graduate student with basic concepts, theories, models, and experimental techniques for polymer solutions; and to provide a reference for researchers working in the area of polymer solutions as well as those in charge of chromatographic characterization of polymers. The author’s incorporation of recent advances in the instrumentation of size-exclusion chromatography, the method by which polymers are analyzed, renders the text particularly topical. Subjects discussed include: Real, ideal, Gaussian, semirigid, and branched polymer chains Polymer solutions and thermodynamics Static light scattering of a polymer solution Dynamic light scattering and diffusion of polymers Dynamics of dilute and semidilute polymer solutions Study questions at the end of each chapter not only provide students with the opportunity to test their understanding, but also introduce topics relevant to polymer solutions not included in the main text. With over 250 geometrical model diagrams, Polymer Solutions is a necessary reference for students and for scientists pursuing a broader understanding of polymers.
Download or read book Luminescence and the Solid State written by R. C. Ropp and published by Elsevier Science Limited. This book was released on 1991-01-01 with total page 453 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the discovery of the transistor in 1948, the study of the solid state has been burgeoning. Recently, cold fusion and the ceramic superconductor have given cause for excitement. There are two approaches possible to this area of science, namely, that of solid state physics and solid state chemistry, although both overlap extensively. The former is more concerned with electronic states in solids (including electromagnetics) whereas the latter is more concerned with interactions of atoms in solids. The area of solid state physics is well documented, however, there are very few texts which deal with solid state chemistry. Luminescence and the Solid State has been written to fulfil this need. The concepts regarding luminescence and phosphors are unique and have been covered extensively providing a useful reference source for anyone requiring such knowledge as a basis for further study. The discussion on the defect state, which is handled in chapter two, can be applied to many other systems, e.g. ceramic superconductors. The book has extensive, useful equations and figures, the derivations of which are simple and easy to follow. This useful, comprehensive text can be used for self-study and should also prove invaluable in a graduate study as an introduction to the solid state and luminescence.
