Nanoflowers activated by ultrasounds help reduce pollution – Journal cover art

Back to Portfolio

Researchers have conducted many different studies on ways to reduce the environmental pollution that is threatening our planet. The scientific community has agreed that photocatalysts are the most effective solution at the moment, since they can eliminate pollution under sunlight exposure.

However, there have been serious limitations to their large-scale application, mainly due to a low efficiency. 

In the article corresponding to this illustration, the authors have synthetized a new film material that is activated by ultrasound waves. This material has a 3D flower-like morphology, and can absorb sunlight and catalyze reactions very efficiently.  

For this journal cover illustration, the client gave me a lot of creative freedom with his article.

After looking at the shape of the nanoflowers described in the article, I came up with the concept of a polluted lake, partially covered by a photocatalytic film on which flowers in the shape of the nanoflowers grow.

In my initial proposal, the polluted area was quite dark and muddy. With the client, we decided to give the image a more positive vibe by having the water more blue and less polluted, and also adding the sun shining in the sky. We also added the chemical formula of the compound on some flowers’ petals, as well as some sound waves which activate the material.

Would you like to collaborate on a cover like this one?
