New insights into structural, optical, electrical and thermoelectric behavior of Na0.5Bi0.5TiO3 single crystals [PDF]

open access: yesScientific Reports
The single crystals of lead-free Na0.5Bi0.5TiO3 were grown using the Czochralski method. The energy gaps determined from X-ray photoelectron spectroscopy (XPS) and optical measurements were approximately 2.92 eV.

Piezoelectric properties of tetragonal single-domain Mn-doped NBT-6 %BT single crystals [PDF]

open access: yesApplied Physics A, 2013
We report a study of properties of Mn-doped NBT-6 %BT single crystals. We show that tetragonal single-domain states can be stabilized by poling along a [001] direction. For carefully prepared crystals, the piezoelectric coefficient $$d_{33}$$

Chap. 6 : Properties of Na 0.5Bi0.5TiO3 and Na0.5Bi0.5 TiO3-based single crystals

open access: yesMaterials and Devices, 2021
Most studies of ferroelectric materials were focused on polycrystalline ceramics. However, it is difficult to improve their properties significantly (particularly piezoelectric one) due to grain/grain boundaries, compositional homogeneity, isotropic ...

Growth of single crystals of 0.75(Na0.5Bi0.5)TiO3-0.25(Sr0.7Ca0.3)TiO3 and characterisation of their electrical properties

open access: yesOpen Ceramics, 2021
Single crystals of 0.75(Na0.5Bi0.5)TiO3-0.25(Sr0.7Ca0.3)TiO3 (NBT-25SCT) were grown by top-seeded solid state crystal growth. X-ray diffraction of a polycrystalline ceramic sample and Raman scattering of a single crystal reveal that rhombohedral symmetry

Direct and indirect air particle cytotoxicity in human alveolar epithelial cells [PDF]

open access: yes, 2014
Air particulate matter has been associated with adverse impact on the respiratory system leading to cytotoxic and proinflammatory effects. The biological mechanisms behind these associations may be initiated by inhaled small size particles, particle ...

Bifurcated polarization rotation in bismuth-based piezoelectrics [PDF]

open access: yes, 2013
ABO3 perovskite-type solid solutions display a large variety of structural and physical properties, which can be tuned by chemical composition or external parameters such as temperature, pressure, strain, electric, or magnetic fields.
