This book includes the most essential first experiments from the 1960's and reviews the progress made in understanding glass formation with the application of pressure in the last ten years. The systems include amorphous polymers and glass-forming liquids, polypeptides and polymer blends. The thermodynamics of these systems, the relation of the structural relaxation to the chemical specificity, and their present and future potential applications are discussed in detail. The book provides (a) an overview of systems exhibiting glassy behavior in relation to their molecular structure and provides readers with the current state of knowledge on the liquid-to-glass transformation, (b) emphasizes the relation between thermodynamic state and dynamic response and (c) shows that the information on the pressure effects on dynamics can be employed in the design of materials for particular applications. It is meant to serve as an advanced introductory book for scientists and graduate students working or planning to work with dynamics. Several scientific papers dealing with the effects of pressure on dynamics have appeared in leading journals in the fields of physics in the last ten years. The book provides researchers and students new to the field with an overview of the knowledge that has been gained in a coherent and comprehensive way.","brand":"WoB","offers":[{"title":"GB \/ NEW \/ GARDNERS","offer_id":57235712409973,"sku":"NGR9783642266270","price":0.0,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0810\/6996\/5613\/files\/9783642266270.jpg?v=1780072109"},{"product_id":"frohlich-entropy-estimation-and-dielectric-calorimetry-book-jacopo-parravicini-9783032214539","title":"Fröhlich Entropy Estimation and Dielectric Calorimetry","description":"This volume highlights the potential of an experimental approach, which offers a relatively simple and inexpensive alternative to conventional techniques. Its basis is the set of changes of thermodynamic variables that occur when an electric field is applied to an ideal dielectric. If these processes are experimentally measured as a function of temperature, and suitable hypotheses are met, many thermodynamic quantities can be derived from dielectric physical quantities. This enables a shift from standard dielectric thermal analysis to a more targeted dielectric calorimetry.   A central parameter affected by the electric field is the entropy variation known as Fröhlich entropy (FE), introduced by H. Fröhlich. When the imaginary part of the static dielectric function is negligible, far from resonances, FE can be calculated, under the right assumptions, from the real part of the dielectric function. Fröhlich suggested that FE reflects the state of order of the system, making it a useful figure of merit.   Assuming this interpretation, FE values offer insight into the behavior of materials, particularly with respect to temperature, phase stability, transitions, and order–disorder processes. Because the underlying assumptions are weak, the method applies to many physical systems and effectively extends traditional dielectric techniques.   FE estimation has been successfully used across diverse areas of condensed matter physics, including dipolar liquids, liquid and nematic crystals, dipolar glasses, organic molecular crystals, semiconductors, metallic nanoparticles, inorganic disordered ferroelectrics, proteins, and enzymes. This breadth demonstrates its reliability and its significant, still underexplored, potential.","brand":"WoB","offers":[{"title":"- \/ - \/ INTERNAL","offer_id":57272675664245,"sku":null,"price":0.0,"currency_code":"GBP","in_stock":true},{"title":"GB \/ NEW \/ GARDNERS","offer_id":57272675795317,"sku":"NGR9783032214539","price":0.0,"currency_code":"GBP","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0810\/6996\/5613\/files\/9783032214539.jpg?v=1780917757"}],"url":"https:\/\/stage.worldofbooks.com\/en-gb\/collections\/advances-in-dielectrics-book-series.oembed","provider":"World of Books Staging","version":"1.0","type":"link"}
