Formation of Y2O3 and Y2O3:Eu(III) by Electrodeposition in Organic Electrolyte.

Journal of the Surface Finishing Society of Japan, 1993
Formation of yttrium oxide by electrodeposition was studied in DMF containing YCl3 and a small amount of water, and rectangular pulse electrodeposition technique was applied. Y2O3 was formed during the electrodeposition, and Y2O3:Eu (III) film was formed also in DMF containing YCl3, EuCl3 and a small amount of water.

Facile green preparation of Y2O3 decorated with ZnFe2O4 using citrus limon (L.) osbeck leaf extract for photocatalytic degradation of malachite green

Applied Surface Science Advances
The Y2O3 decorated with ZnFe2O4 was successfully synthesized using Citrus limon (L.) Osbeck leaf extract for the first time. A modification of Y2O3 with ZnFe2O4 nanoparticles was carried out because Y2O3 is stable but has a wide band gap, making it less ...

Recycling of NiTi Shape Memory Alloys: Fundamental and Technological Aspects of a Vacuum Induction Melting Processing Route

Advanced Engineering Materials, EarlyView.
The present study investigates recycling of NiTi shape memory alloys via vacuum induction melting. An ingot was synthesized from elemental Ni and Ti and subjected to three subsequent remelting cycles. Remelting increases process durations and impurity levels and adversely affects microstructures and functional properties.

Current Status and Challenges in Data Collection for Aerospace Coatings Deposited by Plasma Spraying

Advanced Engineering Materials, EarlyView.
An innovative approach has been integrated into the GRENAT project to optimize plasma spraying and coating performance. Raw materials are accelerated and melted in the plasma generated by torches, creating coatings. Monitoring sensors collect process data which are combined with ex situ characterization data.

The effect of precursor composition and sintering additives on the formation of ß-sialon from Al, Si and Al2O3 powders

, 2011
A study was performed to investigate the effect of increasing the Al or Al2O3 precursor content, above the stoichiometric amount, on the formation of β-sialon by pressureless sintering of Al, Si and Al2O3 powders in flowing nitrogen gas.
