The oils exhibit strong antimicrobial activity and display more potent against bacteria than fungi. Key words: Calycopteris floribunda......
piezoelectric ceramics was prepared by a conventional ceramic sintering technique. The effect of Bi (Mg1/2Ti1/2)O3(BMT) addition on microstructure, piezoelectric, dielectric and ferroelectric properties... kept same values when x≤0.06. The piezoelectric constant d33 increased obviously and the electromechanical coupling factor kp decreased with BMT addition. The excellent piezoelectric properties of d33......
