Ferroelectric niobates with tetragonal tungsten bronze TTB-type structure have shown great technology interest for application in pyroelectric detectors and piezoelectric transducers, sensor/filter in composite. The synthesis ...

We elucidate the dependence of purity and entanglement of two-photon states generated by spontaneous parametric down-conversion on the parameters of the source, such as crystal length, pump beam divergence, frequency ...

Bi 4Ti 3- xNbxO 12 (BITNb) samples, with × ranging from 0 to 0.40 were obtained using a polymeric precursor solution. Rietveld analyses confirmed that the powders crystallize in an orthorhombic structure free of secondary ...

An experimental study of the Polarization Dependent Loss (PDL) is performed in an Optical Recirculating Loop (RCL). The RCL enables to simulate the transmission through various optical links using just one optical fiber ...

The Polar(®) RS800G3(™) rate monitor was released in the market to replace the Polar(®) S810i(™) , and few studies have assessed that the RR series obtained by this equipment is reliable for analysis of heart rate variability ...

Estudos ambientais envolvendo investigação e mapeamento do meio geológico por meio de métodos geoelétricos apresentam resultados satisfatórios para contaminantes iônicos (chorume) que sugerem eficácia no emprego desses ...
