In article number 2008244, Jorge Gascon and co-workers report complete visible-light photo-thermal CO2 conversion to methane using a new composite catalyst based on Ni nanoparticles supported barium titanate. Under optimal conditions, the photocatalyst displays an outstanding CH4 production rate of 103.7 mmol g−1 h−1 derived from its excellent performance light harvesting properties.

Charged Domain Walls In article number 2300005, Petr S. Bednyakov and Jiří Hlinka observe transient domain structure with multiple superdomains containing bundles of ferroelastic subdomains during the paraelectric to ferroelectric transformation in crystal barium titanate under off-axis electric field. Operando optical microscopy reveals that after retraction phase, superdomain boundaries conve...

This paper presents the utilizing of ferroelectric material on antenna application. There are two different ferroelectric had been used on the proposed antennas which include of Barium Strontium Titanate (BST) and Bismuth Titanate (BiT), suitable for Access Points operating in the WLAN IEEE 802.11 b/g and WiMAX IEEE 802.16 within the range of 2.3 GHz to 2.5 GHz application. BST, which had been ...

Stoichiometric tetragonal Bal-xSrxTiO3 (x = 0.23) nanopowders were prepared by stearic acid gel(SAG) method using barium stearate, strontium stearate, tetrabutyl titanate as Ba, Sr, Ti sourcesand stearic acid as complexing reagent. Thermal analysis including differential thermogravimetric(DTG) and TG, Fourier transform infrared spectrometry (FTIR), X-ray diffraction (XRD) andtransmission electr...

Simple thin-film capacitor stacks were fabricated from sputter-deposited doped barium titanate dielectric films with sputtered Pt and/or Ni electrodes and characterized electrically. Here, we report small signal, low frequency capacitance and parallel resistance data measured as a function of applied DC bias, polarization versus applied electric field strength and DC load/unload experiments. Th...

Barium Titanate BaTiO3 is known for both its electric and magnetic properties. The synthesis and characterization of iron doped barium titanate; BaTi1-xFexO3 (x= 0.005, 0.01, 0.015) was investigated with a view to understand its structural, magnetic and electrical properties. A finest possible sample of Iron doped micro particles of BaTiO3 (BTO) with possible tetragonal structure via a solid-st...

New apparatus and a new process for the sputter deposition of modified barium titanate thin-films were developed. Films were deposited at temperatures up to 900 °C from a Ba₀.96Ca0.04Ti0.82Zr0.18O₃ (BCZTO) target directly onto Si, Ni and Pt surfaces and characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and X-ray photoelectron spectroscopy (XPS). Film texture and cryst...

The effect of reduction and re-oxidation firing on the PTCR properties of Sm-doped barium titanate ceramics was investigated for the application in multilayered PTC thermistors. The lattice parameters a, and c decreases monotonically with increasing oxygen concentration in the re-oxidation atmosphere, which seems to be related with an electrostatic Coulomb interaction between an oxygen vacancy ...

So far, the antibacterial activity of some organic and inorganic compounds has been studied. Barium zirconate titanate [Ba(ZrxTi₁-x)O₃] (x = 0.05) nanoparticle is an example of inorganic materials. In vitro studies have provided evidence for the antibacterial activity of this nanoparticle. In the current study, the nano-powder was synthesized by sol-gel method. X-ray diffraction showed that the...
