ERMR 2006 incorporated invited audio system, technical shows, poster shows, and a pupil paper pageant. on the convention dinner party, Dr. David Carlson of Lord company addressed the convention attendees and gave a stirring speech at the background of ER and MR fluids, in addition to present and destiny functions. a special characteristic of the ERMR meetings is they comprehensively conceal concerns starting from physics to chemistry to engineering purposes of ER and MR fabrics held in a common consultation to reinforce the interplay among the scientists and engineers. The periods in ERMR 2006 have been prepared established into Symposia: a) fabrics and b) purposes. issues coated within the fabrics Symposium incorporated: mechanisms, instruction, and characterization of ER and MR fabrics. themes lined within the purposes Symposium incorporated: ER and MR units, regulate platforms, approach integration, and functions. This constitution used to be applied so as to permit interplay among attending scientists and engineers in either the fabrics Symposium and the purposes Symposium, and to augment the loose circulation of rules, and the capability collaborative examine possibilities.

X. . 5 Ekvlm Figure 3. Field strength dependence of PANOX-430 suspension. Figure 4. Electric field strength dependence of storage modulus of the studied ER suspensions. 3 for the PANOX-430 suspension. What is interesting, both the yield stress value and the maximum strain increased with the electric field strength. What is surprising, at least for this particular suspension, the values of the elastic moduli estimated from the initial slope of the three curves are high and seem to be equal. 4. It can be seen that the differences between the modulus values of the studied fluids are considerably bigger than just the differences of the yield stress values measured dynamically in a classic rheometer.

In contrast to the nanoparticles prepared using the microemulsion technique, which were very uniform, the nanoparticles prepared using conventional precipitation appeared irregular in shape and size due to the uncontrolled nucleation and growth that took place in the bulk aqueous phase. The microemulsion process involves the emulsification of an aqueous phase in an organic solvent. In this type of system, known as a reverse micellar system, the high interfacial tension between the water phase and the oil phase is reduced by the addition of a surfactant and possibly some co-surfactants.
