Polyelectrolyte multilayers were self-assembled onto planar glass substrates and midtimode optic fibers . The multilayer thin films deposited on glass substrate
Mechano- electric effect of cement paste was investigated in this paper. As compressive stress was applied on the specimen, an electrical current was observed.
The technology of activation by adding few activators (【1% ) to increase the amount of blends in cement was investigated. The results show that outer activa-ti
