Lanthanum-doped Bi4Ti3O12 prepared by the soft chemical method: Rietveld analysis and piezoelectric properties
(Elsevier B.V., 2008-03-01)
Bi4-xLaxTi3O12 (BLT) thin films and powders with x ranging from 0 to 0.75 were prepared by the polymeric precursor solution. The effect of lanthanum on the structure of BIT powders was investigated by Rietveld Method. The ...

Piezoelectric biosensors for real-time monitoring of hybridization and detection of hepatitis C virus
(Elsevier B.V., 2004-05-01)
The piezoelectric quartz crystal resonators modified with oligonucleotide probes were used for detection of hepatitis C virus (HCV) in serum. The gold electrodes on either rough or smooth surface crystals were modified ...
Analytical expressions to estimate the effective piezoelectric tensor of a textured polycrystal for any crystal symmetry
(Elsevier Science, 2020-12)
This work introduces a set of analytical expressions that simplifies the procedure of obtaining closed-form formulas to estimate the effective piezoelectric properties of polycrystalline aggregates formed by crystals of ...
