Relaxor characteristic and phase evolution of complex perovskite barium titanate bismuth zinc titanate ceramics

Creator:

Triamnak, Narit

Abstract:

Relaxor characteristic of the solid solution (1-x)BaTiO₃-(x)Bi(Zn₁/₂Ti₁/₂)O₃ (BTBZT) was investigated in this research. X-ray diffraction technique and Raman spectroscopy revealed the crystal structure of BT-BZT at various compositions. For compositions with x ≤ 0.08, the solid solutions exhibited clear tetragonal symmetry and transitioned to pseudo-cubic symmetry as the content of...

"We are not all one puzzle piece" : youth voice, homelessness, and positive youth development

Creator:

Nott, Brooke Dolenc

Abstract:

Positive youth development posits that all youth possess the capacity to change and grow as they interact with their contexts. That capacity is activated and nurtured by a beneficial ecological environment often unavailable for homeless youth. Only a limited number of studies focus on the positive development and strengths of...
