Ceria and Modified Ceria: A Reusable Catalyst for the Green Synthesis of 2,3-diphenyl Quinoxaline at Room Temperature
Abstract: Simple, highly versatile and efficient synthesis of 2,3-diphenylquinoxalines is achieved from benzil and o-phenylene diamine using ceria and modified ceria as the catalyst. Modification of ceria is done using different weight percentage of zirconia. The catalysts are characterized by XRD, FT-IR, BET surface area, TGA and EDX-SEM. The advantages of this method are short reaction times, milder conditions and easy work-up. The product could be separated from the heterogeneous catalyst …

Improved Photocatalytic Activity for Removal of Methylene Blue Dye from Aqueous Solutions with La2O3-Modified Ceria Heterostructured Binary Oxide Nanocomposite Particles
Abstract: The current study aimed to examine the photocatalytic efficacy of a bimetallic CeO2-La2O3 hetero-NC in comparison to monometallic CeO2 and La2O3 nanoparticles (NPs), utilizing Methylene Blue (MB)as pollutant sample under natural solar and UV irradiation. The coprecipitation method was utilized to produce a bimetallic CeO2-La2O3 hetero-NC. Following this, the nanostructures underwent characterization through various techniques including FT-IR, FE-SEM, XRD, UV Vis- DRS, Raman, and Photoluminescence spectroscopy. The catalytic activity of …

Ce-TZP/Al2O3 Nanocomposites for Biomedical Implants
Abstract: Ceramic materials are widely used for biomedical applications because of their remarkable biological and mechanical properties. Titanium and titanium alloys are widely used for fabrication of dental implants. The foremost disadvantage of titanium is its dark greyish colour, negative delicate tissue states of the gingiva may prompt to compromised aesthetics. Anyway these days Zirconia implants were brought into dental implantology as an option in contrast to titanium implants. Zirconia seems …
