Mechanistic study of soot reduction in Fe-MOFs modified alcohol-based fuel based on optical experiments and BO-GPR predictive modeling.

This research addresses the soot emission challenges of conventional internal combustion engines by incorporating Fe-based metal-organic frameworks (Fe-MOFs) into alcohol-based fuel. In a constant volume combustion chamber, optical diagnostic methods were employed to examine the spray properties, combustion dynamics, and emission profiles of fuel mixtures with Fe-MOFs concentrations of 20 ppm, 40 ppm, and 60 ppm. Additionally, a BO-GPR algorithm was employed to predict emission outcomes.

[Effect of PEG400 on the luminescent Eu(BA)3/SiO2].

Rare earth organic complexes combined with inorganic compounds can enhanced thermal stability, but inorganic compounds matrix has great influence on the luminescence characteristic of rare earth organic complexes. The luminescence characteristic of organic and inorganic compound material was improved by PEG doping in the material. Eu(BA)3/SiO2 and Eu(BA)3/PEG400-SiO2 were synthesized by Sol-Gel method.
