Recycle Performance of Heterogeneous Catalyst Metal Oxides-Based Layered Double Hydroxide for Oxidative Desulfurization Process of 4-methyldibenzothiophene

Bulletin of Chemical Reaction Engineering & Catalysis, 2023
The desulfurization of oil must be resolved as soon as possible due to a variety of issues, including environmental contamination and protection regulations. It was believed that oxidative desulfurization (ODS) was the most promising method.

Experimental Investigation in the Quaternary Systems Ti–Ni–Al–N and Ti–Ni–Al–O [PDF]

Journal of Solid State Chemistry, 2000
The experimental evaluation of phase equilibria in the Ti-Ni-Al-N and Ti-Ni-Al-O phase diagrams are based on alloy samples, which were prepared of elemental powder blends by argon-levitation melting in a Hukin crucible. The experimental investigation employed X-ray powder diffraction, metallography, SEM, and EMPA techniques in the as-cast state as well

Microstructural characterization, oxidation behavior, and properties of a new Al–Cu–Ni–Mn–Si non-BCC high entropy alloy at 600, 700, and 800 °C

Journal of Materials Research and Technology, 2023
Non-BCC high entropy alloys have been created and characterized in their as-cast and oxidized condition. The effect of Si on the microstructures in Al–Cu–Ni–Mn alloy has also been explored. The microstructure remained unaltered by the addition of Si.
