The synthesis, characterization and evidence of magnetostrictive properties of blends between one ionic polyurethane with carboxylic units and magnetostrictive micropowders (Fe78Si9B13), as well as nanopowders (Fe68,5Co10Sm1,5B20) is reported. The incorporation of magnetic particles in the polyurethane matrix lead to a magnetic behavior directly dependent on their density and dimensions. The best response was achieved for the micropowders with the diameter within 100 – 150 μm range. A good behavior was also evidenced for the compact system composed of microparticles with the diameter less than 60 μm.

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
