Bismuth Sodium Titanate Based Materials for Piezoelectric Actuators [PDF]

open access: yes, 2015
The ban of lead in many electronic products and the expectation that, sooner or later, this ban will include the currently exempt piezoelectric ceramics based on Lead-Zirconate-Titanate has motivated many research groups to look for lead-free substitutes.

An attempt to obtain Bi_{4}Ti_{3}O_{12}-PVC textured ceramics-polymer composites

open access: yes, 2013
Bi_{4}Ti_{3}O_{12}-PVC composites were fabricated. Ceramics powders of bismuth titanate were prepared by the sol-gel method using bismuth nitrate pentahydrate Bi(NO_{3})_{3} \cdot 5H_{2}O and tetrabutyl titanate Ti(CH_{3}(CH_{2})_{3}O)_{4} as precursors.

Current limiting and negative differential resistance in indium oxide based ceramics [PDF]

open access: yes, 2009
Indium oxide based ceramics with bismuth oxide addition were sintered in air in the temperature range 800-1300 ºC. Current-voltage characteristics of In2O3-Bi2O3 ceramics sintered at different temperatures are weakly nonlinear.

Crystallographic and magnetic identification of secondary phase in orientated Bi5Fe0.5Co0.5Ti3O15 ceramics [PDF]

open access: yes, 2011
Oxide materials which exhibit both ferroelectricity and ferromagnetism are of great interest for sensors and memory applications. Layered bismuth titanates with an Aurivillius structure, (BiFeO3)nBi4Ti3O12, can possess ferroelectric and ferromagnetic

Crystallographic texture in ceramics and metals

open access: yesJournal of Research of the National Institute of Standards and Technology, 2001
Preferred crystallographic orientation, or texture, occurs almost universally, both in natural and man-made systems. Many components and devices in electronic and magnetic systems are fabricated from materials that have crystallographic texture. With the rapidly increasing use of thin film technology, where sharp axisymmetric crystallographic texture ...

Bio-inspired mineral growth on porous spherulitic textured poly(L-lactic acid)/bioactive glass composite scaffolds [PDF]

open access: yes, 2008
It has been shown that texture can strongly influence the adhesion, orientation and proliferation of cells onto the surface of biomaterials. Additionally, it is possible to imprint micrometer level textures throughout the scaffolds by melt compounding ...
