Electrorheological(ER) fluids are of high interest because potentially they can provide simple, quiet, and fast interfaces between electrical controls and mechanical systems. However, a problem with ER fluids to date is that the yield strength is too low for many practical applications. The main dra.....

The present invention relates to the construction of hyperbranched polytriazoles and linear and hyperbranched poly(aroyltriazole)s by Huisgen 1,3-dipolar polycycloaddition. The polymers were prepared by A2 + B3 methodology to avoid self-polymerization during monomer preparation and storage. A new cl.....

Most of the dielectric ceramic compositions consist of three or more different lead-based or non-lead ceramics. These materials and their solid solutions can give high dielectric constants (er>10000) but the disadvantage is large fluctuations in the dielectric constant with increasing or decreasing .....
