Electro-optic modulators are among the most important building blocks in optical communication networks. Lithium niobate, for example, has traditionally been widely used to fabricate high-speed due its large Pockels effect. Another material, barium titanate, nominally a 50 times stronger r-parameter and would ordinarily be more attractive material choice such or other applications. In practice,...

Barium-strontium titanate (BST) Ba0.6Sr 0.4 TiO3 and lanthanum-lithium titanate (LLT) La0.5Li0.5TiO3 nanopowders and thin films have been obtained via the modified Pechini route. Polyesterification and complexation processes of gel formation have been examined. Hypothetical models of coordinative polymers formed in sol-gel system have been suggested. It has been shown that BST and LLT solid sol...

The development of new tools and devices to aid in treating cancer is a hot topic in biomedical research. The practice of using heat (hyperthermia) to treat cancerous lesions has a long history dating back to ancient Greece. With deeper knowledge of the factors that cause cancer and the transmissive window of cells and tissues in the near-infrared region of the electromagnetic spectrum, hyperth...

In recent years, the characteristics of ferroelectric barium titanate (BaTiO3) have been studied extensively in materials science. Barium titanate has been widely used for building transducers, capacitors and, as of late, for memory devices. In this context, a precise understanding of the formation of polarization domains during phase transitions within the material is especially important. The...

This work aims to demonstrate the possibility to fabricate ultra-thin polymeric films loaded with an anti-restenotic drug and capable of tunable drug release kinetics for the local treatment of restenosis. Vascular nanopatches are composed of a poly(lactic acid) supporting membrane (thickness: ~250 nm) on which 20 polyelectrolyte bilayers (overall thickness: ~70 nm) are alternatively deposited....

Nowadays various methods are presented for synthesis of barium strontium titanate (BST) nanopowders with different morphology and properties. Each of these (BST)s has got individual characterization that makes it suitable for a special application. Every method has a special quality, causes it to have preference over the other methods. Low processing temperature is a desired point which most of...

Abstract In this study, we prepared a homogeneous fine powder of barium titanate (BaTiO 3 , BT) doped with different concentrations strontium (x = 0, 0.05, 0.125, 0.15, 0.20, and 0.3) having the composition Ba 1-x Sr x TiO (barium titanate, BSr T). XRD patterns Rietveld refinement revealed existence single tetragonal phase structure for BSrxT, 0–20%, cubic BSr30%T. The physical properties pure ...
