The properties of barium titanate (BaTiO3 , BT), such as high dielectric constant and resistivity, allow it to find numerous applications in the field of microelectronics. In this work silicon metal-insulator-semiconductor field effect transistor (MISFET) structures with BaTiO3 thin films (containing La2O3 admixture) acting as gate insulator were investigated. The films were produced by means o...

It is a challenging task for selective hydrogenation of cinnamaldehyde (CAL) to hydrocinnamaldehyde (HCAL) without additional by-product formation. In this work, La2O3 supported high Ni content nanoparticle catalyst was prepared CAL hydrogenation. Meanwhile, Co-La2O3 catalysts were used as reference catalyst. XRD, TEM, STEM-HAADF, XPS, and H2-TPR measurements investigate the physicochemical pro...

An efficient La2O3-catalyzed new route for the carbon-carbon bond formation in particular, symmetrical and unsymmetrical biphenyls has been developed, which proceeds through carbon-carbon coupling reaction of aryl iodides with boronic acids. The reaction provided the desired products in moderate-to-good yields with a wide range of functional group tolerance.

we report on the synthesis, morphology, chemically and structurally of la2o3-co3o4-zro2 nanostructure. the la2o3-co3o4-zro2 nanostructure was synthesized by a method based on the co-precipitation. composite powders have been characterized by xrd (x-ray diffraction), sem (scanning electron microscopy) and bet (brunauer-emmett-teller). x-ray diffraction showed the formation of nano crystalline, l...

Mononuclear La2O3-supported AuIII complexes synthesised from AuIII(CH3)2(C5H7O2) and characterised by X-ray absorption spectroscopy are highly active, stable CO oxidation catalysts at room temperature, demonstrating the importance of the support in stabilizing catalytically active gold species, which need not include zerovalent gold for high activity.

Hydrogen production via steam reforming of biomass derived oxygenates is a promising environmental alternative to the use fossil fuels. The ethanol reaction investigated over Ni and Rh based catalysts supported on ZrO2-La2O3 CeO2-ZrO2-La2O3 mixed oxides, aiming at elucidation role metal support in mechanism. versus shown be highly active more selective with no methane under all conditions studi...

Nanosized composites CeO2–Ag, La2O3–Ag, and TiO2–Ag are a class of nanomaterials suitable for photocatalysis, optical devices, photoelectrochemical elements. Further, nanocomposites with several wt.% silver can be used as creating materials pathogenic virus inactivation pandemic-neutralizing potential. Thus, prospective due to their biological activity. In the present work, were synthesized by ...

Cracking in La(Fe,Si)13-based magnetocaloric materials has been observed to predominantly form around La-rich (La2O3) particles and pose a threat their long-term structural integrity. To understand the formation of these cracks, FIB cross-sectional polishing followed by SEM characterisation was employed study local microstructural evolution after air exposure. Results suggest that volume expans...
