A new type of titanate nanotube (TNT) coating is investigated for exploitation in biosensor applications. The TNT layers were prepared from stable but additive-free sols without applying any binding compounds. The simple, fast spin-coating process was carried out at room temperature, and resulted in well-formed films around 10nm thick. The films are highly transparent as expected from their nan...

Persistent photoconductivity was observed in strontium titanate (SrTiO(3)) single crystals. When exposed to sub-bandgap light (2.9 eV or higher) at room temperature, the free-electron concentration increases by over 2 orders of magnitude. After the light is turned off, the enhanced conductivity persists for several days, with negligible decay. From positron lifetime measurements, the persistent...

Nanomineralogy is the study of Earth and planetary materials at nanoscales, focused on characterizing nanofeatures (like inclusions, exsolution, zonation, coatings, pores) in minerals and rocks, and revealing nanominerals and nanoparticles [1]. With advanced high-resolution analytical scanning electron microscope, we are now capable to characterize solid materials easier and faster down to nano...

Measurements of the strength of magnetoelectric (ME) interactions at microwave and millimeterwave frequencies have been carried out on layered ferrite-piezoelectric oxides. An electric field E applied to the composite produces a mechanical deformation, resulting in a field shift δHE or a frequency shift δfE in the resonance. A stripline structure or a cavity resonator was used. The strength of ...

In this research, the stoichiometric perovskite lead titanate (PbTiO3) nanostructurewas synthesized successfully by the hydrothermal method. The effect of heattreatment of the autoclave and the furnace on the structure of this materialwas investigated. Titanium dioxide (TiO2), titanium tetrachloride (TiCl4) and leadoxide (PbO), lead nitrate (Pb(NO3)2) were used as the ti...

Since lead titanate was ®rst grown in single-crystal form in the 1930s, several independent reports of its linear birefringence have been published. Whilst there is overall qualitative agreement on its behaviour with temperature, the absolute values show some degree of variation. At 298 K they range from ÿ0.009 to ÿ0.013, a relative spread of 40%, whilst at 673 K the discrepancy is even greater...

Piezoelectric principles are widely used to harvest energy in the process of vibrating piezoelectric mass. Different design configurations were studied in the research papers listed. A novel dynamic method of Lead Zirconate Titanate Sensor (PZT) to obtain d33 suitable for the MEMS applications is designed, simulated and analysed results were compared with the fabricated sensor. The Lead Zircona...
