Описание: Today there is an increased focus on a considerable reduction of the total energy consumption in the world. As the heating of buildings constitutes a large part of this consumption, the development of highly efficient thermal insulation materials is highly demanded. The most promising class are polymeric nanofoams, which might be producible by using the "Principle Of Supercritical Microemulsion Expansion" (POSME). Within this approach, microemulsions with a high number density of CO2 nano-pools in a polymerizable material (e.g. polyol) are used as templates. Adjusting supercritical conditions, the nucleation of gaseous CO2 during the expansion is avoided, so that each CO2-swollen micelle should ideally grow to a nanopore. However, due to aging phenomena, so far only polyurethane (PU) foams with microcellular pores could be produced applying this approach. In order to improve the properties of the foamable microemulsion template, microemulsions of the type water - CO2 - non-ionic fluorinated surfactant (Capstone(R) FS-3100) were studied in the first part of this thesis as a model system. Small angle neutron scattering (SANS) measurements for the first time revealed the phase inversion from CO2-swollen micelles in water via bicontinuous structures to water-swollen micelles in CO2. Using a scaling description developed for microemulsions of the type water -alkane - CiEj, the temperature dependence of the length scales found in classical and CO2-microemulsions fall on top of each other. Moreover, the partial replacement of CO2 by cyclohexane was found to increase the efficiency of the fluorinated surfactant to form a bicontinuous microemulsion. This efficiency boosting could be correlated with the increase of the bending rigidities κ0, SANS and κNSE determined by SANS and neutron spin echo (NSE). In the second part of this thesis the gained knowledge was successfully used to formulate CO2-in-polyol microemulsions appropriate for the production of nanocellular PU foams. Usi

Описание: The current state of the art of various aspects of micro emulsion systems is reflected in this volume. Major topics discussed include: general background on solubilized systems, phase diagrams and phase equi- libria, bicontinuous microemulsions, Winsor's phases, theories and models of complex self association structures, cry tical behaviour, phase tran- sitions in lyotropic liquid crystals. I hope that this book will serve its intended objective of reflecting our current understanding of microemulsions both in theory and practice, and that it will be useful to researchers, both novices as well as experts, as a valuable reference source. I feel indebted to the people of the Ettore Majorana Centre: the friendly atmosphere of the Erice centre provided a very effective environ- ment to enjoy the company of colleagues and friends during breaks and after sessions, and to discuss problems of mutual interest. The courtesy, efficiency and devotion of the secretarial and technical staff was also appreciated, and greatly contributed to make the Workshop a smoothly run- ning one. The Scientific Secretary Donatella Senatra Department of Physics University of Florence (Italy) v INTRODUCTION The decision to publish. in a more permanent form than heretofore. the Proceedings of the Workshop on "Progress in Microemulsion" of the Inter- national School of Quantum Electronics. which was held in Erice (Italy) from October 26 to November 1st. 1985. under the auspices of the "Ettore Majorana" Centre for Scientific Culture. will prove to be a sound one.

Описание: "Nanotechnology" is now very well known as one of the most important key technologies in science and industry. In the field of material science and engineering, nanoparticles should be unit materials, as well as atoms and molecules, to build ceramics, devices, catalysts, and machines, and the "nanoparticle technology" is thus attracting. This novel technology includes various methodologies for nanoparticles: preparation, surface-modification via chemical and/or physical treatments, immobilization and arrangement on supports or substrates, to achieve high performance for luminescence properties in light emitting devices, and high efficiency for catalytic and photocatalytic reactions in chemical synthesis, chemical decomposition, and artificial photosynthesis, etc. It should be needless to say that the preparation of nanoparticles, having precisely controlled particle size, size distribution, chemical composition, and surface properties, is essentially important to realize "true nanoparticle technology". This book, written by Dr. Dibyendu Ganguli and Dr. Munia Ganguli, deals with the preparation methodologies for inorganic nanoparticles using macro- and microemulsions as "microreactor". There are several differences between these two emulsions, in addition to water droplet size: thermodynamic stability, and fusion-redispersion dynamics of the droplets. The properties of the nanoparticles prepared in these emulsion systems are seriously influenced and controlled by the selection of dynamic and static conditions.
