This is a recent cover art that I made for the research of Ingrid F Silva and co., which was accepted as a cover for ACS Applied Nano Materials.
The research was about the carbon-nitride compound studied for the catalysis of biodiesel production. Since this compound was the main topic of the study, it was placed in focus and some molecules involved in the reaction were scattered in the background. The yellow liquid represents biodiesel to give the context in general.
