An investigation of the photocatalytic properties of lithium niobate and barium titanate [PDF]

open access: yes, 2012
Efficiency of particulate semiconductors for driving photocatalytic reactions is impractically low due to the recombination of excited carriers and intermediate species at the interface.

Magnetic and electric properties of bismuth ferrite lead titanate ceramics [PDF]

open access: yes, 2010
Solid solutions of multiferroic BiFeO3 doped with ferroelectric PbTiO3 (BFPT) can be prepared by conventional mixed oxide processing to produce a range of polycrystalline ceramics ranging throughout the xBiFeO3 - (1-x)PbTiO3 series. Sintered ceramics are

Heat-to-Electricity Conversion Using Barium Strontium Titanate Multilayer Capacitors. [PDF]

open access: yesAdv Sci (Weinh)
Lead‐free barium strontium titanate multilayer capacitors convert waste heat into electricity via the Olsen electro‐thermodynamic cycle. These capacitors achieve an energy density of 3.7 J cm−3, comparable to the performance of lead‐based ceramics. Their high dielectric strength and broad operating temperature window below 100°C make them practical for

Fotoluminescência em materiais com desordem estrutural Photoluminescence in disordered materials

open access: yesCerâmica, 2004
A grande maioria dos estudos fotoluminescentes foram realizados com materiais cristalinos, cuja emissão ocorre em temperaturas criogênicas, limitando a aplicação destes materiais. Por sua vez, determinados sólidos com alta densidade de defeitos (amorfos),
