      abstract     = {Hollow particles of barium titanate were obtained by a
                      two-step process combining colloidal chemistry and
                      solid-state reaction. BaCO(3) crystals (size ≈1 µm)
                      suspended in a peroxy-Ti(IV) aqueous solution were coated
                      with an amorphous TiO(2) shell using a precipitation
                      process. Calcination of the BaCO(3)@TiO(2) core-shell
                      particles at 700 °C resulted in the formation of BaTiO(3)
                      hollow particles (shell thickness of ≈70 nm) which retain
                      the morphology of the BaCO(3) crystals. Formation of the
                      cavity occurs because out-diffusion of the core phase is
                      much faster than in-diffusion of the shell material. X-ray
                      diffraction (XRD) and Raman spectroscopy indicate that the
                      hollow particles possess a tetragonal ferroelectric
                      structure with axial ratio c/a = 1.005. Piezoresponse force
                      microscopy has shown strong piezoactivity and 180°
                      ferroelectric domains. The process described provides a
                      general route to fabricate hollow ferroelectric structures
                      of several compounds.},
