Workshop Suzdal 2007

Sunday, July 22, 2007 to Thursday, July 26, 2007
Suzdal, Russia

The benefit and hazards of the 21st Century are intimately connected to the mesoscale behavior of multi-bodied, molecular systems, both organic and non organic. Conversely it is the less fashionable methodologies which hold the most promise for the accurate analysis and detection of these systems. Of them the most important is Broadband Dielectric Spectroscopy.

Dielectric relaxation plays a fundamental role in the description of observed physical phenomena in polar systems whose properties are governed by the time evolution of molecular dynamics. The Dielectric Spectroscopy technique occupies a special place among numerous modern methods used for physical and chemical analyses of materials since it can investigate the relaxation processes of systems over an extremely wide range of characteristic times (105 s - 10-12 s). Dielectric Spectroscopy is especially sensitive to intermolecular interactions and is able to monitor cooperative processes at the molecular level. It provides a link between the investigation, via molecular spectroscopy, of the properties of the individual constituents of the complex material and the characterization of its bulk properties. The recent successful developments of the Time Domain Dielectric Spectroscopy method and Broadband Dielectric Spectroscopy have radically changed the attitude towards Dielectric Spectroscopy; it is now recognized as an effective investigative tool for research on solids and liquids at macroscopic, microscopic and mesoscopic levels (See Appendix). Given the interdisciplinary nature and current involvement Dielectric Spectroscopy in research and practical applications, this is a most appropriate time to have an international tutorial in this field. This Training Workshop will bring together experts in dielectric spectroscopy, theory of dielectrics, data treatment and the users of dielectric spectroscopy from Eastern, Western and American countries working in different fields of science and engineering to discuss the most recent advances, explore their interrelationships of their research and stimulate future research and developments.

The main purpose of the Training Workshop is to discuss the current issues as well as the applications of Dielectric Spectroscopy in many disciplines. Scientists utilizing Dielectric Spectroscopy in condensed matter physics, colloid chemistry, glass science and engineering, polymer science, rheology, and biophysics will have the opportunity to discuss the critical issues in Nanotechnology, new materials; life sciences, medical physics; Environmental Security; Landmine Detection etc. Participants will confront each other in a congenial manner on their often divergent views and opinions, thus enhancing the knowledge of dielectric phenomena in complex systems.

Other important goals of the tutorial are to identify new area for exploration and the corresponding experiments that will yield supporting evidence for expected and observed physical properties, and to provide to theoreticians and experimentalists the possibility of becoming acquainted with each other's work. The conference presentations will also be focused on how the instrumentation can be adapted to several major industrial fields.

One of the major applications is the development of progressive technologies for production of novel and advanced materials suitable for military needs. Another major application is aimed at the early cancer diagnostic method by comparing the dielectric behavior of normal to malignant cells and tissues. There is a list of the companies, which could benefit from attending this training workshop and taking part in its work and exhibition. Among them such companies as Agilent, Novocontrol, Solarton, etc., who are directly involved in innovative measurement techniques and instruments for dielectric measurements. Specialists in the theory and measurement dielectric properties will be encouraged to participate in the meeting. Original papers, not presented elsewhere concerning, but not restricted to, the following areas will be sought:

• Broadband dielectric spectroscopy
• Time domain dielectric spectroscopy
• Relaxation theory and data treatment in frequency and time domain
• Dielectric relaxation phenomena in polymers and glass forming liquids
• Dielectric properties of Porous and grain materials
• Dielectric properties of Colloid systems (surfactants, micelles, emulsions and microemulsions)
• Dielectric Spectroscopy in Biophysics
• Dielectric Spectroscopy in nano-physics
